Little question about CCE and multipass VBR

Hi to all,
sorry if this question's already posted but i haven't find anything with search button.
Well my question is:
I'm using CCE and AviSynth to encode some videos. I'm using some filters (like Convolution3D) so the encoding speed is really slow (6 hours on my Athlon 750MHz). So i would like to know if i can make multipass NOT at one time.. and if this quot;methodquot; offer the same results.
For example:
Making the 1st analyzing pass, then choose quot;multipass VBRquot; and select 1 multipass and launch the encoding. When encoding finished, choose another quot;1 pass vbrquot; and launching again. With this method I can make 2-3 multipass in different days... but.. offer the same quality like 2-3 multipass in one time?
I'm using CCE 2.50.
Thanks in advice, sorry for my bad english

Well i'm new to cce but i'd say not possible, as multipass is a work in progress. If you'd encode 1pass after 1pass it'd be 1pass still, you know what i mean?

Sure this is possible. CCE updates the VAF file with every pass, so it retains the bitrate optimizations between program runs. Just make sure you check quot;use existing VAFquot; for you additional passes.

Also you can generate a second MPV which will operate on alternate passes, so if for any reason you have to abort a pass, you can resume only the last pass.

Thanks to all for the replies!

I'm not following this. Can you detail how you would do that? (I'm sure its not hard but I'm missing it somehow.)

Yes, it is not too hard. You have to edit the project and where output is specified, you have 2 MPV file names to fill in. Just use 2 different names, like lt;somethinggt;_odd and lt;somethinggt;_even. I don't recall the exact field names, but it is explained in more detail on the CCE manual.
