Export/convert HD ProRes 422 to MKV
Hi All,
Strange situation here: I need to output a feature film from FCP (ProRes 422 1080p23.98) to a h.264 720p .mkv file. The most widely used tool I’ve found for converting to mkv is HandBrake, but HB doesn’t seem to read ProRes files. Here is the workflow I’ve tried so far:1. Export (1080p or 720p 23.98) ProRes 422 reference movie from FCP
2. Convert to 720p23.98 h.264 .mov file in Compressor
3. Convert to 720p23.98 h.264 .mkv in HandBrakeThe video looks fine, despite the additional transcode (although I’d prefer to just re-wrap the .mov as .mkv), but the audio is out of sync every time. I have also tried converting the ProRes to h.264 in Episode Pro, then continuing with HandBrake, with the same results.
Any thoughts? Thanks for your help!

Right.[Joe Bender] “1. Export (1080p or 720p 23.98) ProRes 422 reference movie from FCP

Avoid H264 or any non production codec.
Transcode (QT is enough) to 8/10b Uncompressed, then to HandBrake.
To get the same results going the H264/Handbrake way, you need to be an expert on that code and on HandBrake operation.

Ok, that makes sense, I’ll give it a try. Many thanks!
