How to Convert ProRes to MP4

Apple ProRes is the professional video codec used in Final Cut Pro, DaVinci Resolve, and high-end editing pipelines. ProRes files are large (often 5–20× larger than equivalent H.264) but offer near-lossless quality for editing. Converting ProRes to MP4 with H.264 dramatically reduces file size for sharing without visible quality loss for typical viewing.

Step-by-step instructions

  1. 1

    Upload your ProRes file

    Select your .mov file with ProRes inside. Common ProRes variants: ProRes 422 Proxy (smallest), 422 LT, 422 Standard, 422 HQ, 4444 (alpha channel). All convert cleanly to MP4.

  2. 2

    Choose MP4 as output and quality

    Select MP4. For social media and YouTube, CRF 22 is excellent. For broadcast delivery, CRF 18. For Vimeo Plus uploads, CRF 17–18 preserves quality margin for the platform's recompression.

  3. 3

    Download and share

    The MP4 is 5–20× smaller than the ProRes source while looking nearly identical on standard displays. Upload to YouTube, Vimeo, or send via email.

Why convert PRORES to MP4?

ProRes is for editing; H.264 MP4 is for delivery. Converting at the end of post-production reduces file size by 90% with imperceptible quality loss.

Frequently asked questions

FFmpeg command for ProRes to MP4?
`ffmpeg -i input.mov -c:v libx264 -crf 18 -preset slow -c:a aac -b:a 320k -movflags +faststart output.mp4`. Use `-preset slow` for better compression at the same quality (slower encoding).
Will I lose quality?
Visually negligible at CRF 18. ProRes preserves more detail than H.264 can represent at any bitrate, but for typical viewing (computer screens, phones, TVs), the difference is invisible. ProRes is for editing; H.264 is for delivery.
What about ProRes 4444 with alpha?
Alpha channel cannot be preserved in standard MP4. For alpha-channel video delivery, use ProRes 4444 (uncompressed) or VP9 with alpha in WebM. MP4 outputs without alpha — flatten transparency to a solid background or keyframe.
