Rescale Video

Aug 2017

As well as transcoding video, we can rescale video, handy for converting HD to SD or UHD to HD. Rescaling can be done when transcoding, or as a step on its own. Please note, if you want to play video back at a certain size, ffplay can rescale the output video, without destroying the source.

This is how to rescale the video, where you specify the framesize:

ffmpeg -i input.mov -vf scale=320:240 output.mov
