AI Video Upscaler: upscale video to 4K with Topaz Video AI

Drop in a clip, pick 2×, 4× or 8×, and Topaz Video AI rebuilds the detail frame by frame — the upscaler editors run on the desktop, hosted here instead, with nothing to install. Switch on smoother motion and it generates new in-between frames as well.

Upscale factor

A multiplier, not a resolution menu: 2× takes 1080p to 4K, 4× takes 540p there, and 8× is for genuinely small source footage.

40 credits

The upscaled clip opens in a session you can come back to, at the factor you picked.

How it works

How to upscale a video in three steps

  1. Step 1

    Upload your video

    Drop in an MP4, MOV, WebM or M4V up to 100 MB. Phone footage, an old camcorder transfer, a screen capture, a clip a model generated too small — anything that needs more pixels than it has.

  2. Step 2

    Pick 2×, 4× or 8×

    The factor multiplies both sides, so 2× is the 1080p-to-4K step and 8× is for footage that started tiny. Turn on smoother motion as well if the movement stutters rather than just looking soft.

  3. Step 3

    Generate and download

    The finished clip opens in a session that belongs to you, ready to download or to carry into another edit.

What it is for

When a clip has to be bigger than it was shot

Delivering in 4K

A channel that shoots 1080p can still publish at 4K. Upscaling before the export gives the platform's encoder more to work with, and leaves a thumbnail frame with detail in it.

Old and home footage

Camcorder transfers, VHS captures and early phone clips were recorded at a fraction of the resolution a modern screen expects. Upscaling brings them closer to the display they were never made for.

Anime and gameplay

Line art, hard edges and on-screen UI text are the first things a plain resize destroys. The upscale reconstructs those edges rather than blending them, which is the whole difference between a resize and a rebuild.

AI-generated clips

Most video models finish well below 4K and at a modest frame rate. Run the output through here to reach delivery resolution, and interpolate the frames when the motion arrives stuttering.

What makes this different

The desktop upscaler, running online

It runs Topaz Video AI

Not a generic super-resolution filter: this page runs Topaz Video AI — the Proteus v4 model for the upscale, and Apollo v8 when you ask for smoother motion. No install, no licence and no GPU of your own: the run happens on our side and the result lands in your session.

Up to 8× on both sides

The factor applies to width and height at once, so 2× is four times the pixels and 8× is sixty-four. Eight is the ceiling. Pick for where the footage has to land rather than for the biggest number: a source that is already sharp gains little from an extreme factor.

It can add frames, not just pixels

Resolution is only half of why old footage reads as old. Optional frame interpolation generates new frames between the ones you shot, up to 60 fps, so a slow pan moves instead of stepping. It is not something the online upscalers usually offer.

Pay per clip, not per month

Video is priced by the second, so a short clip costs what a short clip should. Every plan includes credits, and they work on any other tool on YouArt.

Questions

AI video upscaler FAQ

What is an AI video upscaler?
It is a tool that raises a video's resolution by reconstructing detail in every frame, instead of stretching the pixels already there. A plain resize just makes the same soft picture bigger; an AI upscaler rebuilds edges and texture as it enlarges, which is why 1080p footage can come back looking closer to something shot at 4K.
Is the video upscaler free?
New accounts arrive with free trial credits, which is enough to upscale a short first clip without paying anything. After that the page runs on credits like the rest of YouArt — every plan includes them, and they are spendable on any other tool here.
Can I upscale a video to 4K?
Yes. The control is a multiplier rather than a resolution menu: 2× takes 1080p to 4K, 4× takes 540p there, and 8× is for footage that started genuinely small. Because the factor applies to both sides, an 8× run has sixty-four times the pixels of the original.
Which model does the upscaling?
Topaz Video AI. Proteus v4 does the upscaling, and Apollo v8 generates the in-between frames when you switch smoother motion on. It runs here as a hosted step, so you do not need the software, a licence or a graphics card, and the finished clip lands in your session.
Can it make the motion smoother?
Yes. Optional frame interpolation generates new frames between the recorded ones, up to 60 fps. Turn it on for choppy pans, old low-frame-rate footage and AI-generated clips that stutter; leave it off when the original cadence is the point, such as material you want to keep at a film-look 24 fps.
What can I upload, and how large can it be?
MP4, MOV, WebM and M4V, up to 100 MB per file. That size ceiling is the limit most people actually meet — if a clip is over it, trim it or export a lighter version first and upscale the section you need.
Will it fix a blurry or heavily compressed video?
It will improve one, within reason. Upscaling reconstructs detail the source implies; it cannot recover something the camera never recorded. Compression blocking, mild softness and low resolution usually read better at the larger size, because the model rebuilds edges instead of enlarging the artefacts — but badly out-of-focus or motion-smeared footage stays damaged, just larger.
What happens to the video I upload?
It is uploaded to your own YouArt account so the run can read it, and the upscaled clip opens in a session only you can see. Nothing is published to the community or anywhere else unless you share it yourself.
