Hi, I'm dabbling in transcoding flvs (e.g., from YouTube) to mp4s (for uploading to a service (Snapfish) which doesn't support flv. I'm doing something like this:
ffmpeg -i example.flv example.mp4 I find that the above command line reduces the size of the video to about a third of the original, but at the cost of egregious degradation of the video quality. If I use the 'sameq' option: ffmpeg -sameq -i example.flv example.mp4 the resulting video seems to retain the quality, but now the file size is increased by a factor of four (I've only tested one file so far - the original flv was about 20MB, the first mp4 was about 8MB, and the second about 80MB). Why is this, and is there a happy medium, i.e., a way to keep the size roughly constant, but to retain quality?
