d2Sroba meaning of sample% ?

[churchmouse]

I obviously don't understand something very basic about d2sroba.
I thought that it gave a speed advantage by homing on a quality setting to reach a certain target size of svcd encoding.
I have tried 3.4.0 and 3.3.3. I have default settings. It makes great SVCDs, but as it iterates to find a good Q value, it is encoding the whole movie each time.

The log starts like this
Using CCE version 2.50
--------------------------------------------------------
- Movie length : 01:50:31 (159004 frames, 23.976 fps)
- D2S audio brate : (160 + 0) kbps
- D2S video estim. : 1652 kbps, 2 CDs
- Select Ranges : every 500, select 15 frames
- Sample frames : 159004
--------------------------------------------------------
and indeed it encodes 159004 frames (in this example) every time it tries a new value of Q. I have sample size set at 3% ; I would have thought that it in fact encoded only 3% of the movie each time it evaluates a new Q value.
Is this something to do with the conditional sizing pass? Or do I misunderstand the meaning of sample %?
I have read the faq and quite a few postings.

Its not encoding the whole movie, its sampling the 3% that you specified to find the proper Q. When it samples it should only take between 3-15 minutes depending on what % you requested, if its taking significantly longer than that then there is something terribly wrong. I can normally do a 2 hour movie in an hour and 15 minutes or so.

1% is all I ever use. Its all you need.

Hmm. He is actually encoding the whole movie. I think I saw someone else post the same problem: Number of sample frames equals total frames (159004) - no good. Should only have been about 4770 in your case. I'll try with cce 2.50 myself.

I use CCE 2.5 everyday with no problem. I just don't understand what is happening to churchmouse.

i was having that problem aswell it stopped when i switched to ECC 2.66 and changed sample to 2% but i'm still having other difficulty's @ my pc. at my brothers pc i still have to test but i'm hoping it will work out ;)

how fast will d2sroba be if its a p4 2.66gz compared to 4 pass?

Try v3.4.1 - it computes the number of sample frames itself. A bonus is it doesn't open CCE for that purpose alone anymore. :)

Thanks, the latest version works, and now I am cooking with gas. This is super. Re the previous version, I applied the crc patch to CCE 2.5, in case that is relevant. But who cares, 3.4.1. works like a charm and the churchmouse is tickled pink.
