[FFmpeg-user] how to change the timecode without new encodig - some ideas and questions

[Götz Reinicke]

Hi,

I do have a bunch of Panasonic EVA1 clips, H.246 MOV and I like to change the timecode to a different value.

Googling gave me some hint:

ffmpeg -i file.MOV -map 0 -map -0:d -vcodec copy -timecode 16:21:08:10 fiel_newTC.MOV

That command runs, but changes somehow the file:

a) The size is slightly smaller, e.g. 246.939.019 vs. 247.060.908 Byte
b) The codec is set to „XAVC Intra“

And e.g. VLC can't play that file and Adobe Premiere imports it as just an audio file.

I'm on macOS 12.3.1 with ffmpeg version 5.0.1

What could be my problem?

	Thanks for any help, hint and suggestion . Regards . Götz
