H264 Encoding for Ps3 and Xbox 360 Tests and suggestions

Dear all:

I've purchased a PS3, and, folowing this thread where we discussed encoding possibilities

http://www.dvxuser.com/V6/showthread.php?t=91222

I figured it would be nice if we gatter al useful encoding information for these consumer multimedia machines, in order to achieve the best possible results for output.

Here's what I've got:

Following Bob Gundu's advice, I went with Apple TV encoding preset out of Quicktime pro. While it looked good, it still looked a bit below what I was getting from the native dvcproHD source. SO I tried to up the kb per second to 12000KB per sec. It looked better, but still well bellow the 1080p source. This, however, works.

Then I tried encoding 1080p. Did exactly the same as on the 720p option, only did resize the screen to 1920x 1080. The PS3 says "unsopported format". Bummer. Did it with 12000kb bitrate.

Any H264 output preset from you guys working in 1080?

Haven't tried to up the 720p signal beyond 12000kb. Funny thing is, the H264 Blu rays I have go way beyond 12000 or 18000, for the matter, and they are supposed to be 1080p. How do we get there?

Xbox 360 settings for fellow users could be good, too.
 
Quick update on my tests:

Sony recently released its 1.82 firmware upgrade for the PS3. What this means is that the PS3 is now capable of displaying High quality 1920x1080 h264 files.

Did a quick test, exported a DVCPRO HD 1080p 25 timeline trough Quicktime's H264 encoder, with a variable bit rate average of 18mb, and it played beautifully.

Haven't stretched the encoding to the max, but the bit rate when the video was playing went to a peak of 60mb (!) in certain scenes, and no struggling. Very impressive!

So, PS3 is now a very viable quality display Hub for H264 encoded HD material!

Will continue testing- I will try to up the bit rate to 23 to see what improvements I get.

Do share your experiences!
 
Here's the technical discussion for h.264 playback on PS3

Looks like a lot of issues with ps3 playback unless its level 4.1 or below, 720P, and 2 channel AAC audio in .mp4 container. People still messing around with hex editing files to get more playback options.

And here is microsoft's offical stance on VC-1 and h.264 support in Xbox 360

In case it's too hard to click through each question: .mp4 container only, 4GigaBytes or less, 2channel LE AAC audio, level 4.1 or below, 10 MegaBits per second or less for 1080-30p

I can say with absolute certainty that with the New PS3 firmware you can playback 1080i/p encoded files. I did it, and it plays beautifully. And encoded at an average bitrate of 18mbs.
Encoded from Quicktime export. FIle size limitation I have to check.

UPDATE:

Tried encoding a 1080p 25 file of 32 minutes on 18mb variable bit rate h264. Took about 10 hours to encode on a dual g5 2.7ghz. Results?

Excelent playback on PS3. FIle size 3.9gb
