Can I change a video resolution (say, from 640x480 to 320x240)?


At ubuntuforums there's a thread talking about avidemux, I did a search in the wiki for "resolution" but I found nothing about how to change it. Does anyone use it?

ffmpeg Install ffmpeg

Sorry to write the same againg, but ffmpeg can do this easily too

ffmpeg -i input.mpeg -s 320x240 output.mpeg

There are felt one million additional options to change the output format. These can also be combined

ffmpeg -i input.mp4 -s 320x240 output.mpeg

Thanks! I did a search for "resolution", but I see now it's called "size" in the ffmpeg manual! =) – Tom Brito Oct 10 '11 at 18:44
It's indeed a pain to read the lengthy ffmpeg documentation, mainly because you can do so much with this brilliant tool (you almost forget it has no GUI) ;) – Takkat Oct 10 '11 at 18:47
It has winFF, but it don't work so well.. – Tom Brito Oct 11 '11 at 13:07
