Upscale any clip up to 4K
Upload the clip, press one button and get it back four times bigger, frame by frame. For AI-generated clips, old footage or anything shot on a phone.
- Model: Topaz AI
- 4× upscale, up to 4096px wide
- Takes a few minutes
- Works with a clip from your history too
We take you into the app: that’s where you upload the file and find the result in your history.
The same clip, before and after
Drag the curtain to see the difference on the same frame.
Left: the original clip, 320×180. Right: the same clip upscaled 4× with this tool (1280×720), re-compressed for the web.
Detail the clip wasn’t showing
Topaz AI doesn’t stretch the picture: it rebuilds every frame at four times the resolution. Edges, text and faces come out cleaner than with an ordinary resize.
- Width and height grow 4×
- The aspect ratio stays the same
- You end up with an MP4 ready to post
Get generated clips out of 720p
Plenty of video models generate at 480p or 720p. Run the clip through the upscaler before posting and it holds up on a big screen too.
- Take the clip straight from your Viralio history
- No more downloading and re-uploading
- Start the upscale and close the page
Unlimited from the Studio plan up
On Studio and Business, 4K upscaling doesn’t use credits. You get up to 2 upscales running at once and a fair-use limit of 40 a day.
- 1.5 credits per clip on the other plans
- If the upscale fails, you don’t pay
- The upscaled clip stays in your history

What people ask about 4K video upscaling
How long can the clip be?
It works with clips up to 40 seconds, in MP4, MOV or WEBM. If yours is longer, trim it first.
Does the clip really come out in 4K?
The upscale is 4×, up to 4096px wide. A 720p or 1080p clip reaches 4K. A very small clip still grows 4×, but it won’t reach 4K.
How much does it cost?
1.5 credits per clip. On the Studio and Business plans it’s unlimited, with up to 2 upscales running at once and 40 a day.
How long does it take?
A few minutes, depending on the length of the clip. You can close the page — the clip shows up in your history when it’s done.
Do I pay if the upscale fails?
No. Credits come off only once the upscaled clip is saved to your account.
Can I upscale a clip generated on Viralio?
Yes. In the app you choose “From history” and take the clip straight away, without downloading and re-uploading it.
