Most programs seem to effectively ignore the pts for a frame shown by ffprobe, because they pay attention to the dts for a frame, which is different from the packet dts but usually the same as the frame pts and the packet pts. This can be seen by looking at the packets and looking for similar sizes:įfprobe -hide_banner -show_entries packet=pts_time,dts_time,size ordered-frames-avicopy.mp4 -select_streams v | lessĬould also make arrays and by doing so sort everything by size so you wouldn't have to search to compare packets to frames, but it's easy to look for two or three packets.

They are the packet dts values, which are different from the frame's pkt_dts values. The pkt_dts_time values are just two more than the original file, but the pts values are now completely different. In another terminal tab, compare the new mp4:įfprobe -hide_banner -show_entries frame=pkt_pts_time,pkt_dts_time,pkt_size,coded_picture_number ordered-frames-avicopy.mp4 -select_streams v | less Step 1, generate a video with numbered frames:įfmpeg -filter_complex 'color=white:160x160:1,drawtext='fontcolor=black:fontsize=96:x=(W-tw)/2+4:y=(H-th)/2+4:text=%'' -preset veryslow -refs 8 -aq-strength 0.5 -threads 1 -crf 20 -frames:v 30 -movflags faststart ordered-frames.mp4įfmpeg -i ordered-frames.mp4 -c copy ordered-frames.aviįfmpeg -i ordered-frames.avi -c copy -movflags faststart ordered-frames-avicopy.mp4įfprobe -hide_banner -show_entries frame=pkt_pts_time,pkt_dts_time,pkt_size,coded_picture_number ordered-frames.mp4 -select_streams v | less
