[FFmpeg-user] Captured video is not smooth (Solved but Lip Sync Occur)

[mohamed hefny]

Hello Carl,
 
Thank you very much for your help. Motion is smooth now after using the following command (Removing +ilme+ildct) and Replacing (-Top 1 with -vf yadif=0:1):
 
ffmpeg -f dshow -i video="Decklink Video Capture (2)":audio="Decklink Audio Capture (2)" -y -s 720x576 -r 25 -aspect "4:3" -pix_fmt yuv420p -flags +cgop -vf yadif=0:1 -sc_threshold 1000000000 -g 12 -bf 2 -flags2 +sgop -vcodec mpeg2video -b:v 2800K -maxrate 2800K -minrate 2800K -bufsize 2000k -crf 23 -acodec mp2 -ab 128K -metadata service_provider="MHEFNY" "c:\\outx.m2t" 
 
But the audio is out of sync by about 0.3 Sec, Is it possible to overcome that lip sync.
 
 
Thank you in advance 
Mohamed Hefny

If you mean "combing", the effect shown by interlaced
video, there are several de-interlacing filters in
FFmpeg, yadif is recommended.
(Don't use ildct and ilme on de-interlaced input.)
