Can i skip 1st pass for second time?

[junglemike]

Hi everyone. I have general question.
When i encoding a movie off a dvd - i usually do a two or even 3 encodes. One - is for regualr 1/2 cd-backup (with resolution about 640 and bitrate ~1000kbit or more.) Than i'm doing additional encoding for my palm computer (w/ 480x320 screen , 400mhz cpu), parameters are approx (480x256, 24fps, 200-300kbit, mono audio). And sometimes i also do a third encode for my friend palm (320x320 screen ~150mhz cpu), parameters are: (320x176, 12fps, 100-200kbit/sec, mono audio).

In all these cases - do i have to redo a first pass? (this what i did till now) Or i just can use only one first pass for all 2(3) encodes?

forgot to add, that when i encode for palm - i pre-rotate video with turnright() function. So what do you say?

Yes, you have to redo all first passes, because data passing through encoder changes every time (if you feed the encoder with the same source changing only bitrate you can use the first 1st-pass for all 3, but not in the case you mentioned).

For second question, if your video turns out right, there's nothing to add! I mean, i do not have a palm, but try with and without Turnright(), and see what's the right solution!;)
