1238	Overlaying is late for one frame!	ssp43		"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.
