Hello world and hello ffmpeg-user list! We have roughly 30TB of v210 (uncompressed 8 bit 4:2:2 PAL) Quicktime mov video files, created when digitizing tape. We would like to transcode these to FFV1/MKV for archival purposes.
However, when I’m doing a transcode like this: ffmpeg -i input_file -map 0 -dn -c:v ffv1 -level 3 -g 1 -slicecrc 1 -slices 16 -c:a copy output_file.mkv …. I lose the time code stream (and from what I understand, it’s better not to). How can I retain it? * the command is from https://amiaopensource.github.io/ffmprovisr/#create_FFV1_mkv * below is the output of ffmpeg -i input_file.mov Stream #0:0[0x1](eng): Video: rawvideo (2vuy / 0x79757632), uyvy422(smpte170m/bt470bg/bt709, top coded first (swapped)), 720x576, 165888 kb/s, SAR 16:15 DAR 4:3, 25 fps, 25 tbr, 25 tbn (default) Metadata: creation_time : 2023-08-03T15:09:19.000000Z handler_name : ?Apple Video Media Handler vendor_id : KeyG encoder : Uncompressed 8-bit 4:2:2 timecode : 10:43:59:02 Side data: Frame cropping: 8/9/0/0 Stream #0:1[0x2](eng): Audio: pcm_s16le (sowt / 0x74776F73), 48000 Hz, stereo, s16, 1536 kb/s (default) Metadata: creation_time : 2023-08-03T15:09:19.000000Z handler_name : ?Apple Sound Media Handler vendor_id : [0][0][0][0] timecode : 10:43:59:02 Stream #0:2[0x3](eng): Data: none (tmcd / 0x64636D74), 0 kb/s (default) Metadata: creation_time : 2023-08-03T15:09:19.000000Z handler_name : Time Code Media Handler reel_name : 696_komp_fits_komp_52_betasp timecode : 10:43:59:02 Stream #0:3[0x4](eng): Subtitle: eia_608 (cc_dec) (c608 / 0x38303663) (default) Metadata: creation_time : 2023-08-03T15:09:19.000000Z handler_name : ?Closed Caption Media Handler _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
