Convert Video to ProRes 422 MOV
Create edit-friendly ProRes 422 intermediates locally in your browser — named Proxy/LT/422/HQ tiers, optional downscale, and uncompressed PCM audio. Nothing is uploaded.
About this tool
Use this when you need a real editing intermediate instead of a small delivery file. The output is always a QuickTime .mov encoded as Apple ProRes 422-family video with 10-bit 4:2:2 pixels and an editor-friendly vendor tag. That makes the file easy for NLEs to scrub, trim, grade, and re-export.
A typical default run takes a camera or phone clip, chooses 422 — default general editing tier, leaves Resolution cap at Source size, and writes 16-bit PCM audio. For example, a 128×128 MP4 test clip becomes a .mov whose video stream identifies as apcn (plain ProRes 422), uses yuv422p10le, and keeps uncompressed PCM audio.
ProRes is intentionally large. Plain ProRes 422 is roughly 147 Mbps at 1080p29.97 — about 18 MB per second before audio. Choose Proxy or a lower Resolution cap for offline edits, quick review files, or anything long. The page runs locally in the browser; the CLI/chat path caps input at 32 MiB and output at 128 MiB to avoid surprise memory use.
Limits and edge cases
- This is for ProRes 422 (
proxy,lt,standard,hq). It does not create ProRes 4444, 4444 XQ, ProRes RAW, alpha-channel intermediates, or web-delivery H.264/WebM files. - Resolution cap only downscales. Selecting 1080p for a 720p source leaves it at 720p instead of inventing pixels.
- Browser previews usually cannot play ProRes. Download the
.movand open it in an editor, media inspector, orffprobe. - Converting to ProRes does not restore detail, dynamic range, or color information that was not present in the source.
FAQ
Which ProRes tier should I pick?
Use 422 for general editing. Pick Proxy when you want small offline files, LT when storage matters but you still want a nicer intermediate, and HQ when the clip will be graded heavily or re-encoded several times.
Why is the MOV much larger than my MP4?
ProRes is an intra-frame editing codec: every frame carries enough information to be decoded and scrubbed independently. That makes timeline work smooth, but it trades compression efficiency for editability. Use the Proxy tier or a lower resolution cap if size matters.
Can browsers play the output directly?
Usually no. Most browsers do not decode ProRes even though the file is a standard .mov. The page provides a download; open the result in Final Cut Pro, Premiere Pro, DaVinci Resolve, Avid, QuickTime-compatible tools, or inspect it with ffprobe.
Does this improve the visual quality of my source video?
No. ProRes preserves quality well during editing and repeated exports, but it cannot recover detail lost to a compressed source. It is best used before an editing or grading step, not as a magic quality enhancer.
