Background of issue: I have a new Panasonic 4K video camera that produces its 4K content in h.264 MP4 format (3840×2160). When I use ffmpeg to convert this to the h.265 codec to shrink the file size, I see a couple of errors about a missing key frame and timestamp, but then the file is generated but with serious visual artifacts.
Video from the same camera that is shot natively in just HD (1920x1080 h.264 MP4) quality has no issue when converting via ffmpeg to h.265. Here is the code I used: ffmpeg -i S1000001.MP4 -c:v libx265 -c:a libfdk_aac -crf 28 265-4k.mp4 Here are the errors that I see when I issue the command: [mov,mp4,m4a,3gp,3g2,mj2 @ 0x559875557a40] st: 0 edit list: 1 Missing key frame while searching for timestamp: 3003 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x559875557a40] st: 0 edit list 1 Cannot find an index entry before timestamp: 3003. I've listed the details of the ffmpeg build on my blog: https://wjwoodrow.wordpress.com/2018/04/14/new-camcorder-panasonic-hc-wxf1-but-issue-converting-to-h-265/ I can list them here if that will help. Ffmpeg works fine for converting other HD video, but not the new 4K frame size. -- Sent from: http://www.ffmpeg-archive.org/ _______________________________________________ ffmpeg-user mailing list email@example.com http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
