BDAV multiplexing/authoring (PS3 upscaling)

[sebhag]

Ok, i thought this is gonna be easy, but failed to find any information on this...

I'm trying to backup an entire DVD boxset to a single BD-R, BUT i still want my PS3 to upscale the video as if it's played from DVD.

This seemed easier than it actually is coz the PS3 does only upscale SD content from DVD or BDAV but NOT from BDMV/AVCHD. My initial thought was to just author a massive DVD project with 25GB of content and just burn the image to BD-R, but (surprise, suprise) the PS3 recognises the media type rather than the folder structure and assumes it's a data disc.

Upscaling and re-encoding for BDMV obviously defeats the object so BDAV seemed the solution since PS3 firmware 2.40+ supports upscaling of BDAV (not BDMV though).

So.. i thought great, just use tsMuxeR and convert BDMV to BDAV but to my surprise there's no such tool available other than various consumer authoring tools like Nero which will probably re-encode the video too.

Has anybody got some information on BDAV folder and file structure, specifically info.bdav? Or knows of a BDAV authoring tool that doesn't re-encode?

Thanks.

I'd also be glad if I can get some BDAV samples or more about files/structures. It won't be that hard to implement it in multiAVCHD when no-menu option is used and I guess it will help with playback from SDHC cards.

Hi Deank, glad someone else is showing an interrest and it'd be great if you could add BDAV as an option.

Here's (http://www.mediafire.com/file/hmyomifczmm/PowerProducer-BDAV.rar) a pretty little BDAV example. :) Original video (test.vob) is PAL mpeg2 interlaced with ac3 at 192kbps. There are three versions all created with PowerProducer. One with no chapter points or playlists, one with one added chapter and another one with one added chapter and the same title repeated three times in a playlist.

I'll upload some examples from Nero and MovieFactory if i get a chance, although one is worse than the other.

Hope this helps...

Ok, here's (http://www.mediafire.com/file/dgwtnyjyjem/BD_DiscRecorder-BDAV.rar) another one from Ulead's BD DiscRecorder.

Can't seem to get a BDAV output from latest Nero Vision (only BDMV) but maybe someone else can. According to their website BDAV authoring is not supported in the trial version.

Both, BD DiscRecorder and PowerProducer re-encode the video although it's BDAV compliant. BD DiscRecorder has an option to not re-encode compliant streams but only passes through the ac-3 audio. PowerProducer also re-encodes the audio.

Anybody know how to create a BDAV disc with Nero? And which version?
