Sony SDDS

[nonkeljef]

I've Momento pal R2.It has 2 audio stream, AC3 and Sony's SDDS (1536 bitrate).Both with an audio delay -80ms.Only the AC3 stream is encoded by Besweet. I also get an rebuild error in scenarist and failed. The resulting DVD video ends up 1.2 GB oversized, exactly the size of SDDS stream.
DVD2DVD doesn't support such streams? Or is there something else i have to configure?

Did you try with DVD2SVCD's internal DVDAuthor instead of Scenarist?

Works fine with DTS.........but I must say I haven't encountered SDDS so not actually much help there.

@ralphthedog

DTS just works great for me too.
I tried also to rebuild with dvdauthor and dvdlab pro trial,final size 1.2 GB oversized, exactly the size of the SDDS stream.

Hi,

I've never heard of SDDS, so I doubt very much that D2S supports it. Given that it has such a high bitrate, just stick with AC3. Keeping an audio track with a bitrate of that magnitude would occupy a significant amount of space on the disc, worsening video quality considerably.

Thanks Bob,

SDDS is a special DTS stream developped by Sony. It's also the first time i encountered this on a DVD. It has twice the bitrate of DTS.
The sound is realy outstanding.

Is it a 1536 kbps DTS track?
Could you check if my "delaycut.exe" tool is able to manage it?
I'll appreciate your feedback..

Just checking the really obvious @nonkeljef..........you have lowered the max. bitrate on the bitrate tab so that all your streams combined are less than 10Mbps?

@jsoto
Dvdshrink is till now the only prog that recognizes this stream as SDDS; all the others name it DTS.

@ralphthedog

No, i didn't do anything. I let DVD2DVD do the usual thing (main movie
1 subtitle stream ,2 audio streams AC and SDDS) with or without DSroba
same result. The SDDS stream is extracted but not encoded by Besweet although it has an audio delay -80ms. So i guess the bitrate of the video stream is calculated without that dts stream and when it comes to muxing, its takes that stream too. Sorry i can't post any logfile
because i deleted eveything.

@nonkeljef, not adjusting the Max. bitrate could be a good reason why the authoring stage would fail, might be worth lowering it so your video+audio bitrates are less than 10,000 and give it another go (even lower if your using Scenarist.....8500?).

I wouldn't worry about Besweet, it does not adjust DTS audio delays, it's allowed for at the authoring stage (using DVDAuthor anyway).

@nonkeljef,
Thanks for the test.
