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.

AI Video Upscaler: upscale video to 4K with Topaz Video AI
Drop in a clip, pick 2× or 4×, 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.
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
- Step 1
Upload your video
Drop in an MP4, MOV, WebM or M4V up to 50 MB on Free and Basic, or 200 MB on Pro and above. Phone footage, an old camcorder transfer, a screen capture, a clip a model generated too small — anything that needs more pixels than it has.
- Step 2
Pick 2× or 4×
The factor multiplies both sides, so 2× is the 1080p-to-4K step and 4× is for smaller source footage. Turn on smoother motion as well if the movement stutters rather than just looking soft.
- 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.
Before and after
The same footage, rebuilt at four times the size
A 480 × 270 clip with real compression damage, not a clean frame shrunk down — 4× through Topaz Video AI. Watch the signage and the fruit crates, which is where a plain resize turns to mush. The hard case: a dark handheld phone clip, where sensor noise and compression damage sit on top of each other. Same 4× Topaz Video AI run — watch the guitarist come away from the wall behind him.
What it is for
When a clip has to be bigger than it was shot
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 4× on both sides
The factor applies to width and height at once, so 2× is four times the pixels and 4× is sixteen times. Four 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
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.
