I ran a 1080i59.94 capture today (directly to FFV1 with no dropped frames :] ) and everything was great but the MP4 looks pretty trashy. I noticed that there's logic for setting the profile, and that appears to work as MediaInfo reads the profile as 4.2. That should be enough to make the quality nice, but bitrate ends up being just over 2Mbps, which is definitely not enough for HD. Here's the mediainfo dump

I know we can't use CRF because we're off x264. Is it maybe worthwhile to just define a target bitrate for HD files to avoid this? I can give that a shot.
