Can you tell me which settings could significantly effect the size of a file? Significant being 100MB or more approx. in this case. I know most settings will either try to compress more or take longer :) If you read the MeGUI profiles thread you'll have a better idea what I'm talking about - not bumping it anymore.

I changed HQ-SLOW:

- 1000kbps
- 8 Ref frames
- No Fast P-Skip = Checked
- RDO and Bidirectional for B-Frames = Checked (All B-Frame options now checked)

Using the HQ-SLOW profile at 950kbps produced a good size file (about 40mb larger than same settings at 900kbps) with room for the audio. Is there something fishy perhaps happening in the encoding between 950kbps and 1000kbps o_O

Are you using 2-pass?

Yep, and the default HQ-SLOW profile plus the changes I listed above

did you use automated encoding or the one click mode? Those would result in an automatic bitrate adjustment at some point so whatever you put into the bitrate field would have no meaning.

I'm using automated 2pass, turbo=cheked, no checkmark in lossless, 1000kbps

What's the difference between 2-pass and automated 2-pass? Automated sounds like you don't have to trigger the second pass.

SoulHunter rocks btw :)

Using Flat16 on one computer and V2 on the other produced 778MB (Flat16) and 600MB (V2) with identical settings.

:cool:

[qutoe]What's the difference between 2-pass and automated 2-pass? Automated sounds like you don't have to trigger the second pass.[/quote]That's exactly right.. but then there's the auto-mode.. that's when you press the auto-encoding (or whatnot) button in the main gui and get to enter a desired filesize, and add additional streams to be muxed. Pressing queue means you're using the manual mode.

I think I'm going to try turning off trellis and using mixed 5 ref again. According to some people it was causing large file sizes.

But you checked the quality? I can produce a 50mb file with identical setings than you. This mean absolutely nothing.

Yeah Soulhunter's looks amazing! What it means is his matrix compresses better then Flat16.

Hehe, thanks... ^_^

Maybe I should put the AVC CQMs in my sign as well!?


Bye

there are different avc matrices from soulhunter!

my comparison showed me that soulhunter v2 gave me better results on the clip i tested than v1 (and it was indeed better than default flat)

read about my comparison here (http://forum.doom9.org/showthread.php?t=102006)
