This cam writes Mp4 without a QuickTime timecode track, but it does write ’something’ that ’should’ be (about) correct. (It’s a known issue it’s off by one or two frames when slaved.)
ffprobe -v error -print_format json -show_format -show_streams /Users/bouke/Downloads/Sony\ FX3/PRIVATE/M4ROOT/CLIP/20240227_C6917.MP4 Partial return: { "index": 2, "codec_type": "data", "codec_tag_string": "rtmd", "codec_tag": "0x646d7472", "id": "0x3", "r_frame_rate": "0/0", "avg_frame_rate": "0/0", "time_base": "1/30000", "start_pts": 0, "start_time": "0.000000", "duration_ts": 1261260, "duration": "42.042000", "bit_rate": "4664775", "nb_frames": "1260", "disposition": { "default": 1, "dub": 0, "original": 0, "comment": 0, "lyrics": 0, "karaoke": 0, "forced": 0, "hearing_impaired": 0, "visual_impaired": 0, "clean_effects": 0, "attached_pic": 0, "timed_thumbnails": 0, "captions": 0, "descriptions": 0, "metadata": 0, "dependent": 0, "still_image": 0 }, "tags": { "creation_time": "2024-02-27T10:22:27.000000Z", "language": "und", "handler_name": "Timed Metadata Media Handler", "timecode": "05:37:06:19" } } Now, where is this TC stored? I cannot find it using a HEX editor. And, more important, FCP, Avid MC and Resolve interpret the “timecode” as Drop frame, where there is no indication of that in FFmpeg / FFprobe. Can anyone shed a light on this? thx, Bouke _______________________________________________ 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".
