The value of two pass is in maximizing quality in a limited size / bitrate. If you are at liberty to increase bitrate then one pass will be fine. If size is not an issue use a single pass with vqscale instead of vbitrate. > > after deinterlacing and before any crop or scale. > > It's a matter of taste.

Once you've scaled I imagine deinterlacing will not work. I could be wrong though. For me interlacing looks horrible on a monitor. Deinterlacing with pp=lb the only negative effect I've noticed is slight softening. Anyway, if you deinterlace do it first was my point. So Derek, pick a short bit of video and experiment. There is no One True Way to treat video, try the various options, keep notes, read this list and mplayer-users and build your own scripts that do it your way.
