OK question of the day..What was the main difference of 2 pass (aka VBR) and CBR 1 pass constant...Was it suppose to just give you a nice looking smaller file? The key point being smaller file compare to a nice looking constant 1 pass or is there a quality difference. I can encode 2 pass 960 X (16 mod) (1080p source) at 4000 mb with NO frame drops what so ever. Where as I can do the same thing with CBR at 4500 mb and both play drop free in Mplayer with-in MKV container (xvid video/ AC3/DTS audio). Is that .5 mb doing anything for the quality?

The resolution I was talking about was this:
1280 x 720 = 16:9 or 1.85 use 4000mb 2 pass and 960 X adjusted ratio (16 mod) You have to do the 960 X (16 Mod) for 16:9 (i.e 1920X1080 or 1280X720) or it will drop frames all over the place.
I'm up to 90 or so HD encodes (mkv container) and was just trying to remember what was the big difference between 2 pass and 1 pass encoding other then size. I can go to 4500 MB with CBR and no drop rates compared with 4000 mb VBR with no drop rates.

My Transformers encode was a failure. For some reason, xvid4psp seemed to freeze up during the muxing. The program was responsive, but didn't seem to be making any progress on the encode. Due to other reasons, I had to restart the machine, and the file I wound up with was a finished, working avi file that was only slightly smaller than the original (almost 10 gigs). Nonetheless, XBMC choked on it big time, and dvdplayer could not play the file at all (instant freeze).
This could be due to a bad encode, but everything checks out with the original and encoded files (this was an x264 HD-DVD rip). I used the exact settings given by SokinSan, which I had success with on a previous 720P rip.
Any ideas as to why this encode failed? Others here seem to have had no issues with 1080P conversions.

ryecatcher... I use MEgui for my encodes...did a reencode of Transformers 1080p about 2 weeks ago.. came out real nice with no drops in Mplayer. use 4500mb CBR Xvid keep the digital audio and if you want place it in a MKV wrapper when you do it.
I just tested a dual encode of Mission impossible II one encode with 2 pass Xvid 4000mb DTS and AC3 wrapped in MKV and 1 pass CBR 4500mb DTS and AC3 wrapped in MKV. Source was 1080P HD-DVD rip. Both were resized to 1280 X 528 (16 mod) The 2 pass encode dropped about 21 frame at one location in the film the same place with CBR and a higher bitrate stayed less CPU intensive and no frame drops with Mplayer.. So I think the 2 pass might be too much for the XBOX. SO this would be my revision of the table:
1280 x 720 = 16:9 or 1.85 use CBR 4500MB and 960 X adjusted ratio (16 mod)
1280 x 544 = 2.35:1 use CBR 4500MB keep ratio
1280 x 528 = 2.42:1 use CBR 4500MB keep ratio

I have two 720p blu-ray rips that I'm trying to re-encode, but every time I try to open a file within XviD4PSP, it just hangs, with the little progress window saying "caching..."
Any ideas?
