AI Video Upscaler — FAQ
Upload a low-resolution or compressed video and the AI rebuilds it at 2× or 4× resolution — sharper detail, cleaner edges, better compression. Works on old phone clips, streaming grabs, screen recordings.
Yes. Upscaling costs about 5,000–10,000 tokens per clip depending on length and scale factor. Signed-up users get 10,000 tokens/day free.
MP4, MOV, WebM up to 100MB. Most clips under 30 seconds work well; longer videos take proportionally longer.
A 10-second 720p → 4K upscale typically takes 2–5 minutes. Longer clips and 4× scale can push past 10 minutes. We stream the result back as soon as it's ready.
Topaz Video (the industry-leader, premium quality) and a standard fast upscaler. Pick Topaz for archive footage or anything you'll republish; standard for quick boosts.
2× and 4×. 2× is usually enough to clean up a blurry phone clip; 4× is for taking 480p or 720p sources up to 4K.
The AI hallucinates plausible detail in smooth areas (skin, foliage, etc.) — that's how neural upscalers work. For forensic use cases (legal / CCTV), that's a problem. For creative use, it looks great.
Yes. The audio track is passed through unchanged. Only the video frames are rebuilt.
Yes, to 8K — but the cost and processing time scale with pixels. 4× on an already-4K source is expensive; 2× is usually enough.
Upscaler restores sharpness. For colorization, use our Deoldify tool after upscaling — it's the cleaner pipeline.
No. Input files are deleted immediately after the upscaler fetches them. The upscaled output is kept on our CDN for 24h (7d for paid users).
Yes — POST a video file + scale factor to /v1/video/upscale/. See /api/ for docs.
