When fps varies you of course can't accurately predict the framerate before you start, so the FPS handed off to x264 is an estimate. There is a patch in the dev forum to pass through this info on second passes to correct the bitrate for the actual fps, but I haven't gotten around to testing it and prepping it for checking into the SVN since, really, HB is transitioning more and more to single-pass quality encodes instead of choosing arbitrary bitrates.
I'm hoping to establish some amount of demand for encodes with targeted bitrates / file size. In my situation, I am always targeting a bitrate to fit a particular storage medium, and from what I see in the wild, so are a lot of others.ExDeus wrote:Arbitrary bitrates will still often be necessary as long as storage media have specific constraints. I don't want to keep everything on a spinning disk, so I burn to DVD (spin on demand). I will always be targeting 1/4-DVD (1.07-1.09GB) per episode when backing up 1hr TV shows. That's a common sweet spot to balance quality and size. A look at the encodes out in the wild --- torrents, newsgroups, etc. --- shows that 1/2- or 1-CD encodes are common for standard def encodes, and 1/4- or 1/2-DVD encodes are common for high def.
You're the expert on where HB itself is heading, I'm just saying community demand is still very much alive for target bitrates. Anything you can do to support them will always be appreciated.
