Audio Wav with TC to audio mxf op-atom
Posted: Thu Apr 27, 2023 8:30 pm
Hello,
I am trying to convert audio wave files into mxf opatom audio files with Ffastrans. And convert the timecode to 29.97DF standart.
The conversion works fine, but the timecode part it is a problem.
1) FFastrans picks up the file as a 25 fps framerate, even though it is 29.97 NDF.
2) Using the %start_tc% variable, it picks up a tc that is a little bit off from what it reads in Avid or Davinci. Both Avid and Davinci reads the TC exactly the same!
here is what comes out of FFastrans
I am trying to figure it out, using %info_exiftool% and %info_mediainfo% but the closest I got from a tc with this information was at "Duration String3", but it is HH:MM:SS:MILISSECOND.
How can I get ffastrans to match the TC showed on Davinci? Is there somewhere else I could look into?
I've tested with several other files, and the behavior is similar. Always off by a few frames!
Can you help me steer in the right direction ?!
Thanks guys!
