[FFmpeg-user] pixelated video after inserting a logo

[Joana Moll]

you can try adding the original film frame rate before the input and the
desired output frame rate before the output, that should fix it.


*ffmpeg -i  -r 24 video1.avi -vf "movie=md.png [logo]; [in][logo]
overlay=W-w-10:10[out]" **-r 24 ** -b 1400k   outprueba.avi*

good luck!
