View Full Version : n00b: I can re-use the 1st-pass to redo 2nd-pass with diff filesize?

So I guess I'm too obsessive about this. Even when I was using DivX I would re-encode the entire film if the file was 698MB just to squeeze in an extra 1kbps bitrate. But with DivX, you had to redo both the 1st-pass and 2nd-pass files. Am I correct in saying that this is not the case with Xvid? In other words, I can run a single 1st-pass Xvid then run any number of 2nd-pass Int. runs with different target filesizes until I get it as close to 700MB as possible, right?

Xvid is going to introduce a whole new level of obsessiveness to my process as I can specify the target filesize down to the KB instead of just specifying the bitrate in DivX which will usually change the filesize in steps of 700KB at a time. I already have a dedicated Athlon 2400 encoding machine, but now I might need another one. :)

Yes you can run the second pass as many times as you want, if you're only changing the target filesize! Of course you have to keep the stats file...

Remember that 1 MB = 1024 kB, so you have to multiply your desired size in MB with 1024 to get the size in kB! For your example, 700 MB are 716800 kB!
