AI Video Upscaler & Relight — Push any clip to crisp 4K and re-light the scene in a single pass. Fixes soft focus, noise and flat lighting without a reshoot.

What AI Video Upscaler & Relight does

4K Upscale & Relight repairs footage you thought was unusable. The upscaler reconstructs detail rather than interpolating pixels, so faces, textures and fine patterns survive the scale-up. The relight pass then rebuilds the lighting of the scene — re-key a face, add a rim light, warm up a cold interior, or balance a shot where the window blew out.

Key features

  • Detail-reconstructing upscale from 720p or 1080p to 4K
  • Temporal noise reduction that removes grain without smearing motion
  • Relight engine with key, fill, rim and ambient controls
  • Deblur for soft focus and mild motion blur
  • Batch processing for whole folders of archive footage
  • Preserves the original frame rate and audio track

How it works

  1. Upload your clip or point the tool at a folder.
  2. Choose the target resolution and let the upscaler analyse the source.
  3. Adjust the lighting with the relight controls, or accept the automatic correction.
  4. Render and compare against the original before you commit.

Who it is for

Editors rescuing archive footage, brands upscaling older ad creative for new placements, and archivists restoring family or historical video.

Why teams choose AI Video Upscaler & Relight

Most AI video tools optimise for a single impressive demo. AI Video Upscaler & Relight is built for repeatable output — the same settings produce the same quality on the hundredth export as on the first, and everything you create stays editable. That matters when a campaign needs twenty variants, when a client asks for one more revision, or when a series has to look consistent across a whole season of work.

It also fits into the rest of the OpenFilmo pipeline. Assets you create here can be finished with our other tools, and your brand kit carries through automatically so nothing leaves the studio off-brand. Commercial use is included on every paid plan, exports are watermark-free, and nothing you make is locked to a format you cannot change later. Start with a single render, or compare the plans on our pricing page.

Frequently asked questions about AI Video Upscaler & Relight

Can it fix genuinely out-of-focus footage?

It improves soft focus substantially, but detail that was never captured cannot be fully invented. Results are strongest on compressed or low-resolution sources.

Does it work on vertical video?

Yes. Any aspect ratio is supported.

Will it change my colours?

The upscale pass is colour-neutral. Only the relight pass changes lighting, and that is entirely under your control.

How large a file can I process?

Individual clips up to 10 GB, with batch mode for longer archives.
