## How to resize a video to make it smaller with FFmpeg

ffmpeg -i sd.mp4 -s 320x280 -c:a copy lq.mp4


'-c' is short for -codec, ':a' specifies audio stream(s), 'copy' specifies the copy codec, which copies the stream(s) (in this case audio) without reencoding. Basically the audio streams will pass through. This is common when you are only manipulating the video stream. – jimhark Feb 5 '16 at 23:27
