Quick post. Nothing specific, looking for a discussion. I do know quite a bit about video encoding, and I want to start using AVC instead of DivX and/or MKV for my personal video/movie collection.

Sadly, I don't have "the original copy" for some of these videos, and they are already compressed - i know that converting from one lossy codec to another lossy codec is a BAD thing to do for quality, but I REALLY want my videos to play on PSP, PC and PS3 natively! Plus, AVC is 10 times more advanced than DivX or XviD too :D

So I'm wondering if anyone has any tips or advice in this regard. In particular, I use TMPGEnc 4 Xpress to create my AVC videos for the PSP with the settings below - if anyone has any tips/corrections/optimizations for what I use, let me know what you think is best!

Also, does anyone know of a video file freely downloadable that is really good for comparing video conversion quality and stuff? You know like... something high-def with lots of motion and everything that'd really "stress" codecs quality level and can give a good indication of just how efficient and effective the video format is at certain bitrates. I hope that makes sense.

Oh ONE LAST THING; does anybody know what the FULL FORMAT SUPPORT is for the PSP v5.00 firmware???? I had to guess my AVC encoder settings and trial-and-error to get it to work and don't know if its the best encode! Anyway those TMPGEnc 4 settings are here...

Code:

			MPEG-4 AVC [480 x 272, 25 fps, 2 pass Variable bitrate 1024 kb/s (max. 2048 kb/s)]
 - Profile = Main [other options are Baseline and High]
 - Level = Level 3 [IT GOES UP TO 5.1 WHY CANT THE PSP SUPPORT A HIGHER LEVEL]
 - Size = 480x272 [I want it to be higher but then it the PSP cant play it right.....?]
 - Other = 16:9, 25fps progressive, motion search range 64
 - AVC SPECIFIC = GOP Length at 33; B frame count at 0; Reference grame count at 1; Quantiziations 24/25/27 [I Picture/P Picture/B Picture]; entropy encoding CABAC [better and newer than CAVLC]; and motion estimation subpel mode is quarter pixel.
AAC audio, doesnt matter what it is its VIDEO i'm worried about and AVC only supports AAC audiostream in the same MP4 container anyway.

Thanks in advance guys. While I wait for a reply, I will read the "MPEG-4 AVC/H.264 Information" article and learn more about the technicals, found here. Peace! :)
