Here's your "proof", and why Paul's succinct "perfect" answer was indeed correct The blend filter in your example, combined (n-1) with (n). This messed up the timestamps if you -map the output node of blend suggested earlier such as [D2] - they don't match the "holes" or the missing ones in [C] . Ie. they are not "complementary" . I was looking for a -vf setpts expression to fix and offset the timestamps, or somehow "assume" the [H] branch timestamps, because those are the ones that are complementary and "fit". But it turns out that it's much easier - the input timestamps from blend filter take on the first node. Originally it was [G][H] ; [H][G] makes blend take H's timestamps (Sorry about the long line, I have a problem with "^" split in windows with -filter_complex) ffmpeg -i 23.976p_framenumber.mp4 -filter_complex "telecine=pattern=5,split[A][B],[A]select='not(eq(mod(n+1\,5)\,3))'[C],[B]split[E][F],[E]select='eq(mod(n+1\,5)\,2)',datascope=size=1920x1080:x=45:y=340:mode=color2[G],[F]select='eq(mod(n+1\,5)\,3)'[H],[H][G]blend=all_mode=average,split[D][D2], [C][D]interleave[out]" -map [out] -c:v libx264 -crf 20 testout2.mkv -map [D2] -c:v libx264 -crf 20 testD2pts.mkv -y -- Sent from: http://www.ffmpeg-archive.org/ _______________________________________________ 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".
