idct=5 and DVD-RB

[jcclow]

Is it possible to use this with DVD-RB? I would imagine you can add it to the Filter Editor section, but how would this affect enabling MPEG2Source("Source",idct=7) under the AVISynth options?

Thanks!

You can't add this under Filter Editor because the MEP2Source (and Trim) commmand have custom arguments for each .avs. So you can't just insert the same command into all the scripts.

So, how can you use a different idct? There are 2 ways.


If you use a multi-file search and replace program (I like the freeware InfoRapid Search & Replace) you can:

Turn ON idct=7 in DVD-RB, use 3-click mode
Prepare
Search and replace idct=7 with idct=5 (or whatever) in your .avs files.
Test it to make sure you didn't break anything then continue with encoding.


If you don't want to or can't use a multi-file search replace, you can:


Turn OFF idct=7 in DVD-RB, use 3-click mode
Prepare
Open your .d2v files in a text editor and change:
iDCT_Algorithm=2
to
iDCT_Algorithm=5 (or whatever)

Test it to make sure you didn't break anything then continue with encoding.

I'll give that a try and post my results.

I'm really curious if there's that big of a speed difference using idct=5 and my 3.0 P4 HT. I endoded "Last Samurai" (7.4gb) last night with 4 passes in DVD-RB (CCE 2.67) and the encoding portion took 200 minutes and I was averging about 3.1. Anyone have an factual info on this?
