Turn blurry, low-resolution footage into sharp HD. Upload an MP4 or MOV clip up to 15 seconds and let AI rebuild the detail frame by frame — audio preserved, processed in the cloud.
3 credits / second of footage · up to 15 seconds per run · failed jobs refund automatically
Real examples — same frame, magnified to the same size
Crops shown at each file's own pixel density, identical encode settings on both sides. Nothing is sharpened on one side.

Drop in an MP4 or MOV — up to 100 MB and 15 seconds per run. The file uploads straight from your browser to storage, so clips start fast.
Flat 3 credits per second of footage, and the exact total for your clip is shown before you confirm — no surprises. The AI renders a 1080p-class result and keeps your audio.
AI rebuilds detail frame by frame in the cloud — a short clip comes back in well under a minute. Preview the result in the player, download the MP4, and find it in your history for 30 days.
You pay for the length of your video, nothing else. Credits come from the same packs as every sparkpix tool ($9.99 for 350 credits), and a failed job refunds in full — automatically.
| Video length | Credits | Approx. price |
|---|---|---|
| 5 seconds | 15 credits | ~$0.43 |
| 10 seconds | 30 credits | ~$0.86 |
| 15 seconds (max) | 45 credits | ~$1.29 |
Clips shot on older phones at 360p or 480p look soft on today’s screens. Upscaling them to 1080p — about 3× for a 360p source — restores enough detail to share them without the blur.
Video that went through messaging apps or repeated re-uploads arrives crushed. AI enhancement recovers edges and texture the compression threw away.
Low-res source material sharpened toward HD helps meet platform quality bars — YouTube, client deliverables, course platforms — without reshooting.
Captures recorded at low resolution to save disk space can be upscaled afterward for publishing, keeping text and UI edges legible.
Scaling video up in an editor stretches the pixels you already have. This runs FlashVSR, a video super-resolution model that rebuilds detail frame by frame — which is why the crop above gets back hair strands and leaf edges instead of a larger blur.
Output is about 2.1 megapixels with the aspect ratio preserved and both edges rounded to a multiple of 16. A 16:9 clip lands at 1920×1088 whatever it started as, so a 360p source gains about 3× and a 720p source about 1.5×.
The audio track passes through untouched and a 24fps clip comes back 24fps at the same length. Only the resolution changes, so the result drops back into an edit without resyncing anything.
A short clip finished in about 25 seconds on the current backend (measured September 2026). Failed jobs are never charged, and the credits return to your balance automatically.

The 15-second cap is ours, not the model's — it keeps a single run predictable in both wait and cost. Longer footage is enhanced clip by clip.
Need 4K output rather than 1080p, or a tool built around longer clips? videoenhancer.app is a dedicated AI video enhancer: super-resolution up to 4K, with a 5-second free trial before you pay for anything.
Pricing is 3 credits per second of video, seconds rounded up. A 5-second clip costs 15 credits (~$0.43 on the $9.99 / 350-credit pack), a 10-second clip 30 credits (~$0.86), and a full 15-second clip 45 credits (~$1.29). The exact cost for your clip is shown before you confirm, and failed jobs refund automatically.
MP4 and MOV files up to 100 MB and up to 15 seconds per run — trim or split longer footage and enhance it clip by clip. The output is always an MP4 with your original audio track preserved. Videos already measuring 1440 px or more on the long edge are rejected before any charge, because the output budget would give them nothing.
The output is a fixed pixel budget of about 2.1 megapixels, not a fixed multiplier — the aspect ratio is preserved and both edges are rounded to a multiple of 16. In practice a 16:9 clip comes back at 1920×1088 whatever it went in as, so a 640×360 source is upscaled about 3× and a 1280×720 source about 1.5×. Measured examples: 320×180 → 1920×1088, 1280×720 → 1920×1088, and a 1152×1664 portrait → 1200×1744. It is built for making low-res footage sharp, not for generating 4K — for 4K photo upscaling, use our free HD image upscaler.
Fast — measured at about 25 seconds for a short clip on the current backend. A full 15-second clip takes longer but is normally a couple of minutes, not the 3–5 it used to be before the September 2026 backend change. You can leave the tab open while it runs; the job continues in the cloud either way and the result is saved to your history.
The video you upload is deleted from our storage within 3 days. The upscaled result is stored in your history for 30 days so you can re-download it, then it is removed as well.
Yes to both. The audio track is carried through untouched and the frame rate is preserved — a 24fps clip comes back 24fps, same duration. Only the resolution changes, so the result drops straight back into an edit without resyncing anything.
Different thing entirely. Premiere, Final Cut or ffmpeg stretch the pixels you already have, so a 360p clip blown up to 1080p is the same blur at a larger size. This runs FlashVSR, a video super-resolution model that reconstructs detail frame by frame — hair strands, leaf edges and fabric texture come back rather than being interpolated. The before/after above is the same frame at the same display size, so the difference you can see is the difference in real detail.
Credits are only kept for successful jobs. If processing fails — including videos rejected by the provider’s content filter — the charge is refunded to your balance automatically.
