 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

 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.
