For most short-form video work in 2026, OpusClip is the best AI video upscaler to reach for when the goal is to sharpen a blurry or low-resolution clip inside the same workflow where the clip is cut, captioned and posted. Topaz Video is the pick for pure upscaling quality and control, DaVinci Resolve Studio for upscaling inside a professional timeline, Runway for upscaling alongside generative video, CapCut for a free desktop option, Media.io for a quick browser upscale, HitPaw VikPea for 4K and 8K targets, and Video2X for a free open-source route. We ranked eight tools by the job each does best, then by price, free-tier limits and how clearly each vendor documents what it does.

Updated October 29, 2026. We make OpusClip, so we rank it first for the job named above, and we say plainly where dedicated upscalers may be stronger on pure quality. Every fact about every tool below comes from that tool's own pricing page, docs or help center, read on October 29, 2026. We did not run hands-on tests of the competing tools.

1. OpusClip: Best for upscaling and sharpening a clip inside the workflow where it is also clipped, captioned and posted

OpusClip's Upscale feature uses AI to make blurry or low-resolution footage sharper, clearer and higher definition, with no editing experience required. It lives in the Quick Start menu next to the rest of the product: add a video by YouTube link, file upload or Google Drive import, review the preview, click Upscale, then download the result from the History tab. The same account, which includes the AI video editor, is where long videos become short clips with a Virality Score from 0 to 99, where animated captions are added in 20+ languages, and where clips are posted to YouTube Shorts, TikTok and Instagram Reels. That is the case for ranking it first here: one place to sharpen soft footage and then ship it. Our Unblur Video tool page walks through the flow, and the Upscale help article has the rules.

The limits come straight from the help center. Videos up to 5 minutes long are supported. Upscaled videos stay available in the History tab for 7 days. The Upscale button shows the base credit cost before processing starts (the help center's example is 23 credits). On Pro, Max and Business, 4K upscaling adds 11 credits per 10-second block, rounded up, on top of that base cost; a 30-second video adds 33 credits and a 45-second video adds 55. The help center's plan table shows Upscale on Pro, Max and Business and not on Free or Starter. The public pricing page lists Free ($0, 60 credits a month, watermark, no editing), Starter ($15 a month, monthly billing only, 150 credits), Pro ($29 a month, or $14.50 a month billed annually, 300 credits that roll over for 2 months) and a custom Business plan; Max is named in the Upscale docs but is not shown on that page.

The honest limitations: we did not find an output resolution for the base upscale or a model name in the help center, and the tool page says the tool cannot invent detail that was never captured, so a badly out-of-focus shot will look better but not in focus. The 5-minute cap and the credit cost per run make it a poor fit for upscaling a feature-length archive. OpusClip is also not a dedicated upscaler with per-model controls, and dedicated tools such as Topaz Video may well give stronger results on difficult footage; we have not compared outputs. Choose it if the footage is a clip of 5 minutes or less that needs to look sharper before it is captioned, reframed and posted. Skip it if the job is restoring long archival footage or tuning a specific enhancement model.

2. Topaz Video: Best for the highest-control, local AI upscaling on Mac and Windows

Topaz Video is a dedicated desktop app for AI video enhancement. Topaz's product page describes upscaling old or low-resolution video to 4K and beyond, reducing noise and blur, deinterlacing, restoring archival footage, stabilizing and creating slow motion or interpolated frames. The pricing page lists more than a dozen named models for Topaz Video, including Starlight, Proteus, Iris, Artemis and Gaia, plus cloud access to the Starlight Sharp, HQ and Fast models. It runs on Mac and Windows, either standalone or as a plugin, and the page lists After Effects and DaVinci Resolve among the host apps.

On price, the pricing page lists Topaz Video at $59 a month (the page has an annual and monthly toggle, so confirm the billing term) with unlimited local rendering and 25 monthly cloud credits that expire at the end of each month. Topaz Studio, which bundles Topaz Video with its photo and image apps, is listed at $69 a month or $399 a year with 300 monthly cloud video credits, and a Topaz for Web video plan is listed at $19 a month (down from $29 in a limited-time offer) with 200 cloud video credits. The page also states that the plans include limited commercial use, defined as personal and commercial use for organizations under $1M USD in annual revenue. We did not find a free plan or free trial on the pages we read, so check the current terms.

The limitation is fit, not quality. Topaz Video is a separate app with its own export step, so it adds a stage before captioning and posting. Its pricing page also notes that the Starlight Sharp, HQ and Fast models are not supported locally on Mac and AMD GPUs, so those run through cloud credits. Choose it if upscaling quality and model control matter more than workflow speed, for example for restoration, archival footage or client deliverables. Skip it if the footage is a short social clip that will be captioned and posted straight away.

3. DaVinci Resolve Studio: Best for upscaling inside a full editing, color and finishing suite

DaVinci Resolve's Super Scale is part of the DaVinci AI Neural Engine in the paid Studio edition. Blackmagic Design's Studio page describes Super Scale as high quality image uprezzing that creates 4K and 8K images from HD sources, alongside tools such as face recognition, speed warp retiming, de-interlacing, magic mask and smart reframe. It suits editors who already cut, grade and finish in Resolve and want upscaling inside the same timeline, rather than a round trip to another app.

Blackmagic's site lists a free version of DaVinci Resolve (editing and finishing up to 60 fps at resolutions as high as Ultra HD 3840 by 2160, in 8-bit formats) and DaVinci Resolve Studio at $236 (shown as reduced from $295 on the day we checked). Blackmagic's page describes many AI Neural Engine features as exclusive to Studio, and its main page lists the Neural Engine under Studio, so the free edition should not be assumed to include Super Scale.

The limitation is the learning curve and the scope: Resolve is a full non-linear editor, color and audio suite, which is more than a one-off upscale needs, and the page we read does not describe Super Scale's controls or limits in detail. Choose it if the work already lives in Resolve or a professional editing pipeline. Skip it if the job is a quick fix on a single clip, where a full editing suite is more weight than the task needs.

4. Runway: Best for upscaling alongside AI video generation

Runway is an AI video and image platform built around generative models, and its pricing page lists upscaling as part of the paid plans. Standard lists 4K upscaling, and the Pro and Max plans list "Unlimited 4K video upscaling" along with a Topaz AI Upscale entry. It suits teams that already generate or transform footage in Runway and want to bring the results up to 4K without leaving the platform.

Runway's pricing page lists a Free plan with 125 one-time credits, Standard at $12 a month billed annually (the page shows $15 on the monthly toggle) with 625 credits a month and no watermarks, Pro at $28 a month billed annually with 2,250 credits, and Max at $76 a month billed annually with 9,500 credits that roll over for one month. The page lists 4K upscaling on Standard rather than on Free.

The limitation is that Runway is priced and built around generation credits, so a team that only needs to sharpen existing footage is paying for a much larger platform. We also did not find an input length limit or an output specification for upscaling on the pricing page. Choose it if generation and upscaling happen in the same project. Skip it if the need is purely to clean up recorded footage.

5. CapCut: Best for a free desktop upscale to HD, UHD or 4K

CapCut's AI video upscaler page describes an upscale workflow inside CapCut Desktop: import a clip, open Video, then Basic, then Enhance quality, and choose HD, UHD or 4K as the target before exporting. Imports can come from the device, cloud, Google Drive or Dropbox. It suits creators who already edit in CapCut and want one more step in the same editor.

The page offers a free download of CapCut Desktop, and it tells readers to check the latest product terms to confirm feature availability for their region and app version. It does not state a price for the upscaling step, so see the pricing page before assuming the feature is free on every plan. CapCut's own FAQ is candid that the visible improvement depends heavily on the condition of the source footage and recommends previewing before export.

The limitation is that the workflow is desktop-based, so it does not suit browser-only or phone-only setups, and the page does not document a maximum length or credit cost. Choose it if the edit is already in CapCut Desktop. Skip it if a browser-based tool or a published limit sheet is needed.

6. Media.io: Best for a quick browser-based enhance with no install

Media.io's AI Video Enhancer runs in the browser. Its page describes upscaling low-resolution footage (240p, 360p, 480p or 720p) toward 4K, with 2x and 4x options, plus noise reduction and sharpening in a single pass. The upload panel lists MP4 and MOV support, a maximum duration of 5 minutes, and a resolution range with a minimum of 960 by 960 and a maximum of 2160 by 2160. The page says the tool supports up to 4K output.

Media.io's FAQ says new users get complimentary credits, that referrals earn extra free credits, and that higher-resolution enhancement consumes more credits. Its pricing page shows a Free tier with 3 daily check-in credits, and the paid prices did not load as readable text when we fetched the page, so see the pricing page for current plans.

The limitation is the input ceiling: the 5-minute cap and the input resolution range on the upload panel rule out long recordings and some already-high-resolution sources. Choose it if a single short clip needs a quick fix and no software install is wanted. Skip it if the footage is long or very large.

7. HitPaw VikPea: Best for upscaling 480p to 1080p footage toward 4K or 8K

HitPaw VikPea is a video enhancement app. HitPaw's product page describes upscaling 480p, 720p and 1080p videos to 4K or 8K, removing noise, fixing blurry or over-compressed video, smoothing shaky footage and boosting frame rates up to 60 fps. It lists downloads for Windows and Mac, an online version, and iPhone, iPad and Android apps, supports formats including MP4, MOV, MKV, AVI, FLV and WMV, and mentions cloud-accelerated rendering and a video enhancer API.

The page shows "Try It Free" and "Buy Now" buttons and a discount banner, but the plan prices did not appear in the page text we could read, so see the pricing page for current plans and for what the free trial includes. We could not verify output limits or watermark rules from the sources we read.

The limitation is the verification gap: the 8K claim is HitPaw's own marketing, and without published length limits or trial terms the practical ceiling is unclear. Choose it if the target is a 4K or 8K deliverable from older HD footage and a standalone app is acceptable. Skip it if pricing and trial terms need to be known in advance.

8. Video2X: Best for a free, open-source upscaler for people comfortable with a technical install

Video2X is an open-source project for machine-learning video super resolution and frame interpolation. Its README describes version 6.0 as a complete rewrite in C and C++ with a Windows GUI and installer and Linux packages, using Real-ESRGAN, Real-CUGAN and Anime4K v4 for upscaling and RIFE for frame interpolation. It is released under the GNU AGPL version 3, and the README lists no price.

The README also lists hardware requirements: a CPU with AVX2 support and a GPU that supports Vulkan. It is the only fully free route in this list, which is why it appears here for readers searching for a free AI video enhancer for 4K, but it comes with no vendor support and no cloud option.

The limitation is setup and tuning: choosing a model, scale factor and GPU settings is left to the user, and the README gives no input length limit or guaranteed output resolution. Choose it if cost is the main constraint and a technical install is fine. Skip it if a hosted tool, support or a one-click flow matters.

How we compared these tools

We built this list from each vendor's own pages on October 29, 2026: OpusClip's help center and tool page, Topaz Labs' pricing and product pages, Blackmagic Design's DaVinci Resolve pages, Runway's pricing page, CapCut's upscaler page, Media.io's enhancer and pricing pages, HitPaw's product page and the Video2X README on GitHub. We looked at what each tool does for upscaling, how it is priced, what the free tier includes, input limits, where it runs (browser, desktop or cloud) and how clearly the vendor documents all of that.

We did not run hands-on tests of the competing tools, and we did not compare output quality between them, so this is a comparison of published specifications and pricing, not a quality benchmark. Where a price or limit was not readable on a vendor page, we say "see the pricing page" instead of guessing. Dedicated upscalers, Topaz Video in particular, may produce better results than any all-in-one product on hard footage; if quality is the only criterion, test two or three of these on the same clip.

How to choose

• If the clip is headed for social posts: pick the tool that sits in the same workflow as captions, reframing and posting. That is the OpusClip case, for clips up to 5 minutes on Pro, Max or Business.
• If quality and control come first: a dedicated upscaler such as Topaz Video or HitPaw VikPea gives a separate app and more model choice, at the cost of an extra export step.
• If the work already lives in an editor: DaVinci Resolve Studio and CapCut Desktop both put the upscale step inside the timeline.
• If generation is part of the project: Runway lists 4K upscaling on its paid plans next to its generative models.
• If cost is the constraint: Video2X is open source, CapCut Desktop is a free download, and Media.io has a free tier with daily credits. Check each tool's current terms.
• If the source is very poor: every vendor here is careful to say results depend on the source. Treat an upscale as an improvement to a usable clip, not a rescue for unusable footage.

Red flags to watch for

• Resolution claims with no source caveat. A page that promises 8K from any input is overselling. VEED's own video enhancer page, for example, states that footage not filmed at 4K cannot be turned into true 4K, and that its enhancer adjusts settings such as brightness and sharpness.
• Watermarks on free exports. Always preview a free export before committing a workflow to it.
• Credits that expire or scale with length. Topaz's monthly cloud credits do not roll over, and OpusClip's 4K step adds 11 credits per 10-second block, so a long clip costs more than a short one. Read the credit rules before batching.
• Short input caps. OpusClip Upscale and Media.io both state a 5-minute maximum.
• Short download windows. OpusClip keeps upscaled videos in History for 7 days, so download promptly.
• No manual override. One-click tools hide model and scale choices; if a result looks plastic or over-smoothed, there may be nothing to tune.
• Confusing export with upscaling. OpusClip's help center states that its 4K export is not upscaling and only applies when the source is genuinely 4K.

Frequently asked questions

What is the best AI video upscaler?

It depends on the job. For sharpening a short clip inside the workflow where it is also clipped, captioned and posted, we rank OpusClip first (we make it). For dedicated, high-control upscaling on Mac and Windows, Topaz Video is the specialist in this list. DaVinci Resolve Studio suits upscaling inside a professional timeline, and Runway suits teams that also generate footage. We did not test output quality across tools, so test two or three on the same clip.

How do I unblur a video?

Run it through an AI upscaler or enhancer. In OpusClip, open Upscale from the Quick Start menu, add the video by YouTube link, upload or Google Drive, click Upscale, then download the result from the History tab. See the Unblur Video page for the steps. AI can make soft or compressed footage noticeably sharper, but it cannot fully recover a shot that was badly out of focus.

Is there a free AI video enhancer for 4K?

There are free routes, with limits. CapCut Desktop is a free download whose upscaler offers HD, UHD and 4K targets, Video2X is free open-source software under AGPLv3, and Media.io lists a free tier with daily check-in credits. OpusClip's Upscale is not on the free or Starter plans. Check each vendor's current terms for watermarks, credits and regional availability.

How do I upscale a video to 4K online?

Browser-based options include Media.io, which lists MP4 and MOV input up to 5 minutes and output up to 4K, and OpusClip, which runs in the browser and offers a 4K option on Pro, Max and Business for videos up to 5 minutes. In OpusClip the 4K step adds 11 credits per 10-second block (rounded up) on top of the base cost shown on the Upscale button.

Can AI upscaling add detail that was never in the footage?

Not reliably. AI upscalers infer plausible detail from existing frames. OpusClip's tool page says Upscale cannot invent detail that was never captured, and CapCut's page says the visible improvement depends heavily on the condition of the source. Previewing before exporting is the safest habit.

Is OpusClip's 4K export the same as upscaling?

No. OpusClip's help center says 4K export only activates when the uploaded source is genuinely 4K (3840 by 2160) and is not upscaling. Upscale is a separate feature in the Quick Start menu.

Which OpusClip plans include Upscale?

The Upscale help article lists Pro, Max and Business, and not Free or Starter. The public pricing page lists Free, Starter, Pro and Business, so see the pricing page and the help article for the current plan names.
