Xvid max bitrate

how high can you go with xvid.. im starting to use 865mb cd sizes (for dvd).. i was lookin at a bitrate calc and i saw that if i was to do this one movie it would be pushing 1900 for video and thats with an ac3... is there a limit? and if no are ther any downsides to going that high? thanks :)

With unrestricted profile i believe you can go over 10000kbit.

Its not so much the bitrate with standalones as it is the bitrate spikes. Most can handle 4000kbps no problem, including my ESS based standalone, but XVID is real bad to have spikes where one frame is 5-10 times the average frame size, which will cause the player to hiccup and continue playing. I run a single pass encode at a quant of 2, open up the resulting file in DRFanalyzer, look for frame sizes in excess of 80000b and note them. I then run a second encode at a quant of 2, but setting zones for those high bitrate/spiked areas at a lower quant...usually a quant of 3 is sufficient, but I have had to go as low as a quant of 4 for certain scenes. Its not a method for the lazy thats for sure, especially since DRFanalyzer only sets a line for the highest frame and the rest you have to guesstimate the frame size visually. But it works for me and thats what I intend to do until they fix XVID.
