Can FFmpeg convert from ArriRaw MXF sources?
Is FFmpeg capable of transcoding from ArriaRaw to h.264?

Not directly, Ari needs to be debarred first at least.
Does that mean using ArriRaw computer or Resolve? Is there no process under the FFmpeg umbrella?

AFAICT currently you have to use either the arriraw converter from Arri or Resolve/Premier. Is there a particular reason you can't use the Arri converter? z!

Arri’s converter is command line and multi-platform, so it may well coordinate nicely with FFmpeg.

arri's cmd line exporter doesn't mention piping possibility https://www.arri.com/en/learn-help/learn-help-camera-system/tools/arriraw-co... On Sun, Feb 17, 2019 at 5:59 PM Carl Zwanzig <cpz@tuunq.com> wrote:

Is there a command to tell FFMpeg to read LTC from a specific audio track?
Updating this question: is FFProbe able to read and report LTC recorded onto a specific audio track? What we've got are MP4 production files, some from A-Cam, some from B-Cam, each with TC, but which were not (or could not) be jam synced. So to create sync the production crew used an external TC generator and recorded it to A1 of both cameras. So our goal: ignore the camera-generated TC track, and use the A1-recorded LTC as the basis of our sync in post. Premiere Pro, for whatever reason, was unable to read the LTC off audio track, in spite of having a number of options for it. Resolve was able to read it, so we know it's valid and functioning, but using Resolve for this many files: manually importing, reading, then reporting the TC is not an efficient way of working. We're hoping there's something in the world of FFMpeg / FFProbe might be able to help here.

I do not know about that ....but would it help if you made a second file - now with Tc in it meaning you have a file dog.mp4 w ltc tc in audio and you know it starts w tc of 07:00:00:00 so do a ffmpeg -i dog.mp4 -codec copy -/timecode/ 07:00:00:00 dog_wtc.mp4 MP4s and MOVs store only the TC of the first frame, as a literal frame count, along with the framerate. The consuming app converts that frame count back to a TC string using the framerate -timecode hh:mm:ssSEPff Specify Timecode for writing. SEP is ’:’ for non drop timecode and ’;’ (or ’.’) for drop.

de-Bayered? Thanks..
Arri’s converter is command line and multi-platform, so it may well coordinate nicely with FFmpeg. That’s just the command line tool though. They do have an SDK, but you need to apply become a partner to get access.
Also, raw files from camera sensors in general aren’t just decoded, they’re rendered to a colorspace. Wouldn’t you want to review the original (for grading, etc) before doing anything with it using ffmpeg?
