[FFmpeg-user] How to add zoom in effect to a video?

[Alfredo Aiello]

Hi,
yes, the scale filter avoid the shaky effect when I have an input image, 
but with an input video, problem is the same.

I red your suggest in this ticket https://trac.ffmpeg.org/ticket/4298.
In a comment, slhck suggests to use ffplay instead.
