For videos that I will NOT be encoding in MainConcept, what different bitrates should I use?
For example..as I mentioned a few posts ago, this is what I use when I capture for a video that I do encode "for when I capture, (everything I capture is 2 hrs 30 min - 3 hrs) the bitrate that Im using is Constant Bitrate, 15,000 bitrate, No Bitrate Peak and 720x480"

For a video that is about 2 hrs long and I WILL NOT be encoding it in MC, should I use Variable bitrate, 4,900 bitrate, 5,900 bitrate peak? Does that sound about right?

Yeah, that sounds about right. :)
