Hoi,

Trying to figure out how to get avconv to concatenate a bunch of .bmps together into a video file.

Here's what I've got so far:

avconv -f image2 -i Capture/%d.bmp -vcodec mpeg4 -r 24 -b:v 20M Capture.mkv

While this does work, the quality is terrible - there are tons of artifacts that are visible, the colours are distorted and everything is blurred.

I've trawled through the documentation for avconv and ffmpeg, but can't find anything that increases the quality.

Any ideas as to how I can get the quality as close to the original bmps as possible?

Thanks for lending me your brains, - Alex
