Upscale your entire film to 4K. Scene by scene.
A 90 minute film is too big for one upscaling pass. Melies splits MP4/MOV masters into reviewable chunks, upscales each one with Topaz, lets you compare and retry until every scene looks right, then rebuilds the full movie with your soundtrack.

Why one upscaling pass fails on a full film
Upscalers are built for clips, not movies. Pushing a feature film through a single pass is slow, fragile, and impossible to quality-check.
Providers reject huge files
A 90 minute master runs into upload caps, processing timeouts, and duration limits long before the first frame is enhanced.
One failure restarts everything
If a single pass fails at minute 80, you pay and wait all over again. With chunks, you only retry the part that needs it.
No quality control
Upscalers behave differently on grain, faces, and dark scenes. A movie deserves a review pass on every section, not blind trust.
How the long film workflow works
Four steps from a heavy master file to a finished 4K movie. Chunking is free, and you approve every upscale before it runs.
Upload your film, get a chunk plan
Drop in your master file, up to 25GB in MP4 or MOV with H.264/HEVC video. Melies splits it into 2 to 5 minute chunks at scene-safe points with stream-copy chunking, and extracts the soundtrack for the final rebuild. This step is free.

Upscale chunks with Topaz
Run chunks one at a time or batch the whole film at 2x or 4x. Each chunk shows its exact credit cost up front, priced per second of footage. If an upscale fails, your credits come back automatically.
Each chunk is priced per second, shown before you run it.
Compare attempts and pick the best
Review every chunk in a synced side-by-side player or with the crosshair reveal. Re-upscale anything that does not hold up, compare attempts, and mark the best one. Only the chunks you re-run cost credits.
Re-upscale any chunk and keep the version you prefer.
Rebuild the full movie
Once every chunk has a selected result, one click joins them and remuxes the soundtrack in sync. Download a single 4K master file, ready for delivery.
Chunks are joined into one 4K master file.
Review tools made for picky eyes
Every chunk gets a dedicated comparison player, so you judge the upscale on your footage, not on faith.
Side by side, perfectly synced
A double player keeps both versions frame-aligned while you play, pause, and scrub. Drift is corrected automatically, so what you see is a true comparison.
Crosshair reveal
Both versions stacked on top of each other with a divider that follows your cursor. Sweep across faces, textures, and titles to see exactly what the AI recovered.
Not convinced by a result? Re-upscale the chunk as many times as you want and keep the best attempt. The rest of the film is untouched.
Honest, per-second pricing
Upscaling a movie is real compute, and we price it like one: per second of footage, by output resolution. Uploading and chunking are free. Every chunk shows its exact cost before you run it, and failed upscales are refunded automatically.
| Output resolution | Credits per second | 3 min chunk |
|---|---|---|
| Up to 720p | 1.5 | 270 credits |
| Up to 1080p | 3 | 540 credits |
| Above 1080p, up to 4K | 12 | 2,160 credits |
Output resolution is your source resolution times the scale you pick (2x or 4x). You can start with a single chunk to judge quality before committing to the whole film.
