Hello, We would like to transcode v210 (uncompressed 8 bit 4:2:2 PAL) Quicktime mov video files to FFV1/MKV for archival purposes.
ffmpeg crops these files, using Quicktime's CLAP atom (clean aperture value). We would like to preserve the full 720 pixel width. How can I do that? I'm using this standard command: ffmpeg -i input_file -map 0 -dn -c:v ffv1 -level 3 -g 1 -slicecrc 1 -slices 16 -c:a copy output_file.mkv FYI MediaInfo reports this about the original Quicktime file: Width : 720 pixels Clean aperture width : 703 pixels Height : 576 pixels Clean aperture height : 576 pixels Display aspect ratio : 4:3 Clean aperture display aspect ratio : 4:3 and this about the resulting MKV: Width : 702 pixels Height : 576 pixels Display aspect ratio : 4:3 The files were created using Final Cut Pro 7 and an Aja Kona card. Sample file: https://videolooper.de/696trim.mov Strangely enough, HandBrake doesn’t crop when using their FFV1 preset. _______________________________________________ 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".
