Yes If you take a soft telecine input, encode it directly to rawvideo or lossless output, you can confirm this. The output is 29.97 (interlaced content) . > When I do 'telecine=pattern=5', I wind up with this > > |<--------------------------1/6s-------------------------->| > [A/a_][A/a_][A/b_][B/b_][B/b_][C/c_][C/c_][C/d_][D/d_][D/d_] 55-telecine > > I have confirmed it by single-frame stepping through test videos. No. Pattern looks correct, but unless you are doing something differently , your timescale is not correct When input is vob, mpeg2-ps or mpeg-es using soft telecine in my test, using telecine=pattern=5 the output frame rate is 74.925 as expected (2.5 * 29.97 = 74.925). This mean RF flags are used, 29.97i output from decoder. Since its 74.925fps, the scale in your diagram for 1/6s is wrong for telecine=pattern=5 Both ffplay and mpv look like they ignore the repeat field flags, the preview is progressive 23.976p -- 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".
