Best AI Video HDR Upscalers for Post Production 2026

Beeble SwitchHDR is the best overall AI HDR upscaler for a color-managed post pipeline; Runway Ruby is the fastest route for 30-second Runway shots, but its $95 Max access floor and unpublished per-run credit rate make it a workflow buy, not a transparent conversion price. LTX wins on unit economics at $0.20 per 1080p second, Topaz wins when restoration and HDR must stay local, and DaVinci Resolve Studio is the finishing layer rather than the reconstruction engine.

Best AI video HDR upscalers: the verdict

Pick Beeble SwitchHDR when a colorist needs control over what the model reconstructs. Pick Runway Ruby when the footage already lives in Runway and clips can stay under 30 seconds. LTX HDR is the clean API choice, Topaz Video is the local restoration choice, and DaVinci Resolve Studio is where the result becomes a defensible master.

The ranking is about the file that reaches post, not the brightest demo. A 16-bit EXR sequence in ACES, the color-management standard used to move images between VFX and grading systems, leaves room to inspect and shape the result. A 10-bit HDR10 or ProRes delivery can be excellent, but it is closer to an output than an editable reconstruction layer.

There is a more important caveat. SDR-to-HDR AI does not recover ground-truth light that the camera discarded. It generates plausible information where highlights clipped or shadows collapsed. Beeble states this plainly: original radiance is gone once it is clipped. That makes review, masking, scopes, and an SDR trim part of the cost, not optional polish.

HDR upscaling and 4K upscaling are different jobs

A larger frame is not a wider dynamic range. Resolution upscaling creates more pixels; HDR reconstruction expands the usable brightness and color representation. One can happen without the other, which is why a generic “4K AI upscaler” list is a poor buying guide for post-production HDR.

Use one evaluation brief across the shortlist. Start with a hypothetical 10-second, 1080p, 8-bit Rec.709 product shot. The window is clipped, a black jacket loses texture in the shadows, and a saturated red package must remain on-brand. The delivery target is a 16-bit ACES EXR handoff for grading, followed by a 4K HDR master and a credible SDR trim.

The before state has three separate defects:

• The 1080p frame needs spatial detail for a 4K timeline.
• The 8-bit SDR source has limited latitude in the highlights and shadows.
• Compression noise and edge ringing may become more visible after either process.

The after state is not “more vivid.” It is a shot that survives motion, scopes, compositing, and a second display format. The bright window needs plausible structure without boiling from frame to frame. Jacket texture must return without turning into crawling synthetic grain. The package color must remain controllable after the transform. The SDR trim must not crush the work back into an unusable image.

The practical order is to lock the edit, remove obvious noise and compression damage, perform any necessary spatial upscale, reconstruct HDR, grade the result, then make and inspect the SDR trim. Reversing the first two image operations can make the HDR model elaborate compression blocks or make a later upscaler sharpen generated highlight texture. There are exceptions, but that is the safer default for the evaluation.

The craft bar

Judge every candidate on five things that a product page cannot decide for your footage:

1. Highlight plausibility: does reconstructed detail obey the scene's light, or does it invent an attractive but wrong sky, sign, or reflection?
2. Shadow behavior: do dark fabrics and hair retain texture without chroma noise, banding, or a waxed surface?
3. Temporal consistency: does the new information hold between frames, especially across camera motion and occlusion?
4. Color pipeline: can the result enter the working color space without an improvised transform or destructive bake-in?
5. Delivery resilience: does the HDR master look intentional on a calibrated display, and does its SDR version remain usable?

1. Beeble SwitchHDR: best overall for controlled HDR reconstruction

Beeble SwitchHDR is the strongest overall choice because it lets a colorist constrain the generated part of the image instead of accepting a full-frame guess. It converts 8-bit SDR footage into 16-bit half-float ACES2065-1 EXR, supplies a Rec.2020/HLG MOV preview, and returns separate highlight and shadow mattes for further work.

That control changes the risk profile. A luminance threshold can isolate the clipped window in the shared brief, while a prompt can describe what belongs in the selected region. Everything outside the mask remains tied to the source, according to Beeble's live SwitchHDR page. The model still reconstructs rather than retrieves lost radiance, but it gives the operator a boundary and editable mattes instead of baking one global interpretation into the shot.

The handoff is the other reason it ranks first. ACES2065-1 is a scene-linear interchange space designed for carrying a wide range of image data between departments. Nuke, Resolve, and Flame can ingest the EXR sequence; the HLG MOV provides a fast display check; the two mattes let the compositor or colorist attenuate the generated regions. That is a post-production package, not only an enhanced video file.

The wall is duration and resolution. A SwitchHDR run accepts up to 240 frames and 1080p. At 24 fps, that is 10 seconds. A 30-second spot therefore needs at least three segments, with extra attention at the boundaries. Four-kilopixel support was still described as coming later in 2026 when the page was checked. For long interviews, concerts, or archive programs, this is a shot workflow rather than a one-click batch remaster.

Pricing is simple enough to model. Creator costs $19 monthly or $16 per month on annual billing and includes 540 credits. Professional costs $75 monthly or $60 per month on annual billing and includes 2,400 credits. Both paid plans include the VFX toolkit and commercial use. SwitchHDR consumes 3 credits per second at 720p and 10 credits per second at 1080p in the live comparison.

A full 10-second 1080p job therefore consumes 100 credits. Creator carries 54 seconds of 1080p HDR conversion per month; Professional carries 240 seconds. At complete allowance use, that is about $0.35 per second on monthly Creator or $0.30 on its annual-effective price. Professional lands at about $0.31 or $0.25. Unused capacity and failed shots raise the accepted-output cost.

Best for: Colorists and VFX teams that need controlled reconstruction and editable mattes.
Standout: Prompted, region-masked SDR-to-HDR with ACES EXR, HLG preview, and separate highlight/shadow mattes.
Pricing: Creator $19 monthly or $16 monthly annual-effective; Professional $75 monthly or $60 monthly annual-effective.
Free trial: No free HDR allowance was stated on the live plan page.

1. 1

   Choose the hardest representative shot

   Use a 10-second or shorter shot with both clipped highlights and weak shadow texture. Keep a brand color, skin tone, or neutral reference in frame so drift is visible.

2. 2

   Constrain the reconstruction

   Set highlight and shadow thresholds before writing a prompt. Ask for the physical content that belongs in the selected region, not a stylistic adjective that could repaint the shot.

3. 3

   Inspect the three deliverables

   Check the HLG preview on an HDR-capable display, import the ACES2065-1 EXR into the grade, and use the mattes to compare reconstructed areas against untouched source pixels.

4. 4

   Stress the result

   Push exposure and saturation farther than the final look, inspect motion frame by frame, then build an SDR trim. Artifacts that survive only at the intended grade can be acceptable; artifacts that break under a modest adjustment are not.

2. Runway Ruby: best for 30-second Runway-native shots

Runway Ruby is the easiest new route from a Runway asset to a professional HDR container, but its missing public unit price keeps it behind Beeble for a budgeted post pipeline. Runway's 21 August announcement says Ruby accepts uploaded or generated SDR clips up to 30 seconds, then delivers 16-bit EXR sequences or 10-bit and 12-bit ProRes and HEVC in BT.2020 using PQ or HLG.

For a studio already using Runway, the advantage is fewer handoffs. A generated shot can stay in the same asset system for review and conversion, and 30 seconds covers a complete commercial shot or several edited inserts without the 10-second segmentation Beeble requires. ProRes and HEVC are practical editorial and delivery options; EXR keeps the high-latitude route open for compositing and grading.

The limitation is commercial, not cosmetic. Ruby is available on Max and Enterprise. The live Runway pricing page lists Ruby's surrounding plan access and says Max includes studio-grade ProRes, image sequences, and HDR generations up to 16-bit, but it does not publish a Ruby credit rate. A buyer can price entry at $95 for a month of Max, yet cannot calculate cost per accepted HDR shot from public information.

That unknown matters when the conversion is the purchase. It matters less when Max already pays for the wider generation workflow. Max includes 9,500 monthly credits, one month of rollover, first access to new models, and the platform's highest listed generation volume. If a creative team already consumes that allowance for image and video work, Ruby can be an incremental production capability. If the team wants only SDR-to-HDR conversion, a $95 access floor plus an unknown draw is hard to approve beside LTX's published rate.

Every Runway tier was checked on 22 August 2026. Free is $0 with 125 one-time credits. Standard is $15 monthly or $12 per month effective on a $144 annual bill, with 625 monthly credits. Pro is $35 monthly or $28 per month effective on a $336 annual bill, with 2,250 monthly credits. Max is $95 monthly or $76 per month effective on a $912 annual bill, with 9,500 monthly credits. Enterprise is custom-priced with custom credits, team controls, SSO, analytics, onboarding, and priority support. Ruby itself begins only at Max.

The practical failure mode is treating bit depth as proof of source truth. A 16-bit container can carry more range and withstand stronger processing, but Ruby still has to synthesize what an 8-bit source clipped. Inspect specular highlights, faces crossing bright backgrounds, branded color, and any effect that depends on exact plate fidelity. A beautiful EXR is not automatically a faithful plate.

Best for: Teams that generate, review, and finish short assets inside Runway.
Standout: Up to 30-second conversion with EXR, ProRes, or HEVC delivery choices in a single creative workspace.
Pricing: Ruby requires Max at $95 monthly or $76 monthly annual-effective, or custom Enterprise terms.
Free trial: No; Ruby is listed for Max and Enterprise.

The wider Runway pricing breakdown explains how its shared credit pool, billing cadence, and Max rollover affect the rest of a creative operation. The HDR decision should sit inside that budget, not beside it as a free extra.

3. LTX HDR: best API and transparent per-second cost

LTX HDR is the best choice when a pipeline needs a callable endpoint and finance needs a rate that can be multiplied before work starts. The asynchronous v2/video-to-video-hdr endpoint accepts SDR video and returns a ZIP of per-frame EXR images for grading or HDR rendering.

The price is public and resolution-based. LTX charges $0.20 per input second up to 1080p, $0.40 up to 1440p, and $0.80 up to 4K. A 30-second source costs $6, $12, or $24 at those tiers before storage, transfer, orchestration, and review. That makes a bid estimate easy to build and a usage dashboard easy to reconcile.

Request caps create the operational cost. At 24 fps, one request holds about 7 seconds up to 1080p, 4 seconds up to 1440p, or 2 seconds up to 4K. A 10-second 1080p shot therefore costs $2 but needs at least two requests. A 30-second 4K shot costs $24 and needs at least 15 requests. Shot boundaries, retries, polling, ZIP handling, EXR storage, and reassembly become engineering work even when the model rate looks small.

The endpoint preserves input resolution. That is important: LTX's “HDR Upscale” name refers to dynamic range, not a spatial jump from 1080p to 4K. If the source is soft, resolve that defect in a separate stage. The clean design is useful because it stops one black-box operation from making two unrelated image decisions, but it also means another tool may be required.

LTX still labeled the HDR route beta on the live vendor pages. Beta is not a synonym for unusable; it is a procurement and reliability flag. A production integration needs retry logic, response validation, storage lifecycle rules, version pinning where available, and a manual escape hatch. The same test shot should be kept as a regression asset whenever the endpoint changes.

Best for: Productized pipelines, render queues, and studios that need usage-based billing.
Standout: A direct asynchronous HDR API with per-second prices at three input-resolution tiers.
Pricing: $0.20/sec up to 1080p, $0.40/sec up to 1440p, $0.80/sec up to 4K; enterprise terms are available through sales.
Free trial: No free HDR allowance was stated in the live documentation.

For builders, this is the same distinction that separates an impressive model from an operable system: the call price is only one line. Queueing, auditability, asset retention, and human approval decide whether the pipeline survives Monday morning. The broader AI video generator comparison helps choose the upstream source before this finishing stage.

4. Topaz Video: best local restoration plus HDR

Topaz Video is the best local choice when the source needs denoise, artifact repair, spatial upscaling, and HDR treatment before it reaches the grade. Its model set includes Proteus, Iris, Nyx, Rhea, restoration and interpolation options, plus the Hyperion and Hyperion 2 SDR-to-HDR family.

That breadth earns Topaz a place that the HDR-only services cannot take. The shared 1080p brief may need compression cleanup and a spatial 4K upscale before any dynamic-range reconstruction. Topaz can keep those operations in one desktop application, with previews and unlimited local rendering. Confidential footage can remain on the workstation rather than moving through another cloud service.

The critical limitation is workflow placement. Topaz's SDR-to-HDR documentation says the feature is not available in its After Effects or DaVinci Resolve plugins. Its cloud-rendering documentation also excludes SDR-to-HDR. Hyperion work therefore happens locally in the standalone Topaz app, followed by another export and import. That roundtrip is manageable for selected shots; it is a burden when a timeline changes hourly.

Personal has three billing routes. It costs $59 month-to-month, $39 per month with a 12-month commitment billed monthly, or $299 prepaid annually, equal to $25 per month effective. The annual prepay saves $169 against paying $39 for 12 committed months. Personal includes unlimited local rendering, 25 monthly cloud credits, the listed SDR-to-HDR models, and commercial use for organizations under $1 million in annual revenue.

Pro costs $74 per month on a 12-month commitment billed monthly, or $699 prepaid annually, equal to $58 per month effective. It adds supported local Starlight variants, seat management, 100 monthly cloud credits, and full commercial use. The live page did not show a true month-to-month Pro tier. Starlight local support also has hardware qualifications, so procurement should match the exact GPU and operating system before buying Pro for those models.

Topaz's local economics improve with volume, but “unlimited” describes software rendering, not free compute. GPU depreciation, electricity, storage, operator attention, and render queue delay remain. A studio with idle capable hardware can treat that capacity differently from a producer who must buy a workstation for one restoration job.

Best for: Editors restoring soft, noisy, compressed, or archival footage on local hardware.
Standout: Multiple restoration and spatial-upscale models plus Hyperion SDR-to-HDR in one desktop app.
Pricing: Personal $59 monthly, $39 monthly on a 12-month commitment, or $299 annually; Pro $74 monthly on a 12-month commitment or $699 annually.
Free trial: The live pricing page did not state the HDR export allowance for a trial.

5. DaVinci Resolve Studio: best finishing system, not automatic recovery

DaVinci Resolve Studio is the tool that makes an HDR result deliverable, but it should not be mistaken for the same kind of generative SDR-to-HDR model as Ruby, SwitchHDR, LTX, or Hyperion. Resolve combines editing, color, VFX, audio, scopes, metadata, and mastering in one color-managed environment.

The free edition costs $0 and supports work up to 60 fps at Ultra HD 3840 x 2160, including HDR grading. Resolve Studio 21 costs $295 once. Studio adds professional 10-bit formats, work up to 120 fps and 32K, HDR10+ and Dolby Vision grading and rendering, HDR scopes, AI UltraNR, SuperScale, and de-interlacing. Advanced Dolby Vision trim controls require a separate Dolby license.

SuperScale is the AI upscaler in the conventional resolution sense. Blackmagic describes it as high-quality image uprezzing that can create 4K and 8K images from HD sources. It is not documented as reconstructing missing HDR radiance. Resolve can transform, grade, tone-map, and master an SDR image into an HDR container, but a color transform cannot retrieve clipped camera information on its own.

That distinction makes Resolve the fifth “upscaler” but the first finishing purchase. Beeble and LTX return EXR sequences designed to enter a grade. Ruby can return EXR or professional video formats. Topaz needs a roundtrip back into the timeline. Resolve supplies the scopes, color-management decisions, shot matching, metadata, and SDR trim that turn those intermediate assets into a deliverable.

The wall is expertise. A node tree, correct input transform, HDR working space, calibrated monitoring path, and delivery metadata can all be configured badly. Studio's $295 license is cheap beside a failed master, but the software does not replace a colorist's judgment or a calibrated display. For a team without that capability, budget a finishing partner instead of treating the license as the whole cost.

Best for: Color-managed finishing, validation, and HDR/SDR delivery.
Standout: SuperScale, HDR scopes, HDR10+/Dolby Vision support, and the complete post timeline.
Pricing: DaVinci Resolve Free $0; DaVinci Resolve Studio 21 $295 one time.
Free trial: The Free edition is permanent, but it does not include the complete Studio toolset.

The budget consequence: price the accepted master, not the transform

The cheapest model call is not the cheapest approved HDR shot. The first-project software floor for a new buyer, using one 30-second 1080p source and adding a $295 Resolve Studio license, is $301 with LTX, $314 with one month of Beeble Creator, $354 with one month of Topaz Personal, or $390 with one month of Runway Max.

Those totals are deliberately narrow. LTX includes $6 of model usage. Beeble, Topaz, and Runway include one entry month, not a per-shot charge. None includes tax, source preparation, uploads, EXR storage, local compute, failed runs, colorist time, quality control, or delivery. Ruby's unknown credit rate also means its $390 is an access floor rather than a completed-output quote.

The fixed-workflow comparison is starker. Topaz Personal prepaid annually plus Resolve Studio costs $594 in year one. Runway Max prepaid annually plus Resolve Studio costs $1,207, a $613 difference. That does not prove Topaz is better value for a Runway studio, because Max also funds generation, review, models, storage, and other creative work. It proves that Ruby should not inherit the entire Max value proposition when HDR is the only requested outcome.

Use accepted-master cost as the budget line: software access plus usage plus compute plus operator and colorist time, divided by approved shots. If five submitted conversions produce one usable master, multiplying the model's per-second price by source duration understates the outcome cost by a factor of five before labor.

The decision rule that flips the purchase

Choose LTX while low, irregular volume and automation matter more than interactive control. Its 1080p usage reaches Topaz Personal's $299 annual price at 1,495 seconds, about 24.9 minutes. Above that volume, Topaz's unlimited local rendering can win if hardware and operator capacity already exist. Choose Beeble when one avoided repair pass repays its premium over LTX. Choose Ruby when the team already earns value from Max and the 30-second cap removes segmentation work.

This is the handoff premium: the extra amount worth paying when a tool delivers the right files, controls, and review artifacts for the next department. It is the only coined concept this comparison needs. A cheap transform that arrives in the wrong container, without masks, or with undocumented credit burn can cost more downstream than the premium it saved.

Who should pick what

A colorist should pick Beeble; a Runway studio should pick Ruby; an engineering-led pipeline should pick LTX; a restoration desk should pick Topaz; every serious delivery owner should keep Resolve in the chain. The flip comes from the constraint that is hardest to change later.

Pick Beeble SwitchHDR when the shot contains clipped regions that need selective reconstruction, when ACES EXR is the expected handoff, and when prompt plus mask control can prevent a destructive full-frame guess. Skip it for long-form batch work unless the production is already organized shot by shot.

Pick Runway Ruby when assets are generated or reviewed in Runway, a 30-second single pass removes operational friction, and Max already earns its $95 monthly place in the budget. Skip it when finance needs a public per-conversion rate or when HDR is the only Runway capability being purchased.

Pick LTX HDR when software submits jobs, variable usage is preferable to a seat, and the pipeline can handle asynchronous polling, EXR ZIPs, short requests, and retries. Skip it when an editor needs interactive regional control rather than an API job.

Pick Topaz Video when the source first needs denoise, de-artifacting, face work, or spatial upscaling, and when confidential footage should stay local. Skip it if the extra standalone roundtrip will break a fast-changing editorial schedule.

Pick DaVinci Resolve Studio when the team owns the master. It is also the fallback when generative HDR creates uncertainty: a skilled colorist can decide that a conservative grade of the SDR source is more truthful than an invented highlight.

How these tools were picked

The five tools were selected for distinct professional jobs, then verified against live vendor pages on 22 August 2026. No product was represented as hands-on tested. The evaluation used documented inputs, outputs, controls, price, caps, color-pipeline fit, and the operational wall a buyer hits after the demo.

The field was narrowed by four questions:

• Does the tool reconstruct dynamic range, spatial resolution, or both?
• What file and color space reach the next department?
• Can a human constrain the generated region, or only accept the output?
• Is the cost a seat, a credit pool, local compute, or a measurable per-second call?

Five products match the current ranking leader's count, but each receives a complete buying block instead of a feature blurb. Generic 4K enhancers without a documented HDR role were cut. Native HDR generators were also cut when they did not solve conversion of an existing SDR source.

No active PartnerStack partner fits professional AI HDR post-production closely enough to deserve a place. Adding a phone, CRM, training, or web tool would make the ranking less useful, so none was inserted. Monetization follows relevance; trust comes first.

The ones to avoid for professional EXR and ACES work

Avoid Aiarty Video Enhancer and UniFab HDR Upconverter AI when the required handoff is a 16-bit EXR sequence in ACES. Both can suit consumer HDR delivery, but their live pages document a different endpoint.

Aiarty Video Enhancer

Aiarty Video Enhancer 3.7 combines 4K enhancement with SDR 8-bit to HDR 10-bit conversion, three look modes, and an HDR strength slider. Its product page labels HDR experimental. Standard was $79 per year during the live promotion, while Lifetime was $165. The free trial processes up to 120 seconds, adds a watermark, and does not support batch export.

That package is appealing for a creator who wants an inexpensive local 10-bit HDR result. It is not the pick for the shared VFX brief because the verified product and pricing pages did not document 16-bit EXR or ACES output. Use it for a compatible HDR delivery after checking the target display; do not promise an editable scene-linear handoff it does not advertise.

UniFab HDR Upconverter AI

UniFab HDR Upconverter AI converts Rec.709 SDR to 10-bit HDR10 or Dolby Vision, supports DCI-P3 and Rec.2020, and can run locally or through FabCloud. The individual lifetime module was $129.99, while UniFab All-In-One lifetime was $429.99 on the checked page. Its documented modes reach 4K and make sense for streaming, home-theater, and direct HDR deliverables.

The same boundary applies. The verified pages did not document 16-bit EXR or ACES output. Pick UniFab when HDR10 or Dolby Vision is the finish. Skip it when a compositor needs scene-linear frames, mattes, and latitude for a heavier grade.

The Monday move

Next Monday, approve one hard shot and a $25 usage ceiling before anyone annualizes a plan. Use the same source, the same target color pipeline, and the same review checklist. Do not start with a showreel-friendly landscape; choose the shot most likely to expose temporal, highlight, shadow, and brand-color failures.

1. 1

   Lock the source and target

   Select a 10-second or shorter 1080p, 8-bit Rec.709 shot. Write down the desired intermediate, preferably ACES EXR for this evaluation, the HDR delivery format, and the required SDR trim.

2. 2

   Run two routes, not five

   Use the decision guide to choose the specialist front-runner and one contrasting route. A colorist might compare Beeble with LTX; a Runway team might compare Ruby with Beeble; a restoration desk might compare Topaz with a conservative Resolve grade.

3. 3

   Review beyond the beauty frame

   Inspect the whole motion sequence, waveform, parade, vectorscope, and highlight/shadow mattes where available. Push the grade, return it to target, then inspect the SDR trim on a separate display path.

4. 4

   Record accepted-master cost

   Log software access, credits or seconds, compute time, operator time, colorist time, retries, storage, and final approval. Annualize only after that sheet shows which handoff reduced work rather than moved it.

The best result may be a hybrid: Topaz cleans and upscales, Beeble reconstructs selected dynamic range, and Resolve grades and masters. It may also be a restrained Resolve finish with no generative HDR at all. The Monday decision is not which model makes the most dramatic frame; it is which workflow produces a reviewable master without hiding cost or synthetic detail.

For teams evaluating broader AI editing behavior before finishing, the Gemini Omni Flash video-editing analysis covers the upstream question: whether the model is making an editable change or merely returning another generated asset.

Frequently asked questions

Which AI video upscaler is the best?

Beeble SwitchHDR is the best overall choice for controlled professional HDR reconstruction because it supplies ACES EXR, masks, prompts, a preview, and editable mattes. Topaz Video is better when the main problem is local denoise, restoration, and spatial upscaling before HDR.

Is AI 4K upscaling worth it?

AI 4K upscaling is worth it when low spatial resolution is the visible defect and the output reduces manual repair enough to justify compute and review. It does not create HDR latitude, so evaluate resolution and dynamic range as separate stages.

Can you use AI to upscale video quality?

Yes. AI can reconstruct spatial detail, reduce noise, interpolate frames, or generate plausible HDR information. Professional use still requires temporal review, scopes, a color-managed handoff, and an SDR trim because generated detail is not recovered camera truth.
