Hi!
I try to overlay the same scaled frame on each frame of my video:
ffmpeg -i Video.m2v -vf "split [out1] [out2]; [out2] scale=iw/4:ih/4
[patch1]; [out1] [patch1] overlay=20:50 [out]" -target pal-dvd -y
Video_new.m2v
And I see that overlaying is late for one frame!
Log-file and screenshots of frames in attachment.
You can take any video with quick frame change and you will see.
