Does anyone have a method for finding the best bitrate/resolution for Xvid or lavc with mencoder.
The only tool I have seen for linux that has a compressibility check comparable to Gordian Knot's is tuxrip, does anyone know what it does? (btw I ran a compressibilty check with lavc and xvid selected and they came out identical? does this make sense?)
What is the significance of the bitrate of the first pass of an Xvid encode? Is it supposed to be the limit of the codec? Should I use that as a guidline to set the bitrate for the second pass?
lavc makes you set the bitrate on both passes or it defaults to 800, So if Xvid's first pass will help me find the sweetspot how should I do it with lavc.
On a sidenote has anyone played with the autoaspect option for lavc? You don't have to scale the Movie at all allowing you to preserve the full original resolution. The downside of this is MPlayer is the only player that will play it back at the correct aspect ratio (this includes Xbox Media Center which uses Mplayer).
