Doing 1st pass then doing 2ndpass at a later time.. How?

[duckdown]

Hi folks, had a question..

Let's say I have a 10 minute high resolution mpeg file, and I wanted to load it into VDubMod and do the 1st pass on it, but then do the 2nd pass on it at another time.. How do I do this?

I tried encoding the clip as "Two Pass - 1st pass" and un-checking "Discard first pass" and it creates a .avi file of the 1st pass, but when I load that 1passed .avi file into VDubMod and select "Two Pass - 2nd pass" mode and try to resize it down to the appropriate size, it actually creates a BIGGER .avi file and does NOT resize it down to the size I selected

Can someone tell me what the proper process is here? Thanks in advance!!

Xvid creates a statistics file in 1st pass (encoding type / more / stats filename). That and the source are the only things you need for the 2nd pass. Keeping the 1st pass AVI is not necessary.

However any filtering, resizing, cropping etc. must absolutely be identical in both passes.

Thanks for the response so far.. But for example, lets say I have 3 video clips that make up one entire show.

part01.mpg
part01.d2v
part01.avs
part01.stats
part02.mpg
part02.d2v
part02.avs
part02.stats
part03.mpg
part03.d2v
part03.avs
part03.stats


Now all 3 of these parts have had the first pass completed on them, but now, how do I combine ALL THREE segments into one solid stretch of video to do the final 2nd pass on them?

ie: not doing an individual 2nd pass on each clip but loading all 3 completed segments and doing the complete 2nd pass on all 3 pieces?

I tried opening part01.avs then "Appending segments" to add part02.avs and part03.avs but Append Segment is GREYED OUT

I am so close but am stuck.. Any advice would be great

Thanks alot!

Why not just have one AVS for all of them?

[duckdown]

I just tried making a new .d2v file, with all 3 pieces combined, and made a single .avs file for the new .d2v .. and the full show loads into vdubmod properly, but when I try to encode it, it just complains about stats file not found.

I only see a place to specify ONE stats file so even if I specified part01.stats , that is only good for the first segment of the show

Please help

You must do both 1st and 2nd pass on the identical source material. That means you have to run both passes on the combined source file. You cannot simply reuse the existing stats files.

However any filtering, resizing, cropping etc. must absolutely be identical in both passes.

It's good advice for newbies, but you can easily substitute a faster deinterlacer, denoiser, etc as long as they're fairly similar. First pass is already pretty imprecise anyway. Resizing and cropping definitely change things, though.

hello
you could create a new avs script to join them
just try

a=directshowsource=("C:\part01.avs)
b=directshowsource=("C:\part02.avs)
c=directshowsource=("C:\part03.avs)
return(a+b+c)

in a new avs script and try searching for mkvextract GUI to take out the audio it will also take out subtitles and video that can be put together by an app like VirtualDubMod
