Limited Success: HDV to playable Blu-Ray - Page 3 - Blu-ray Forum

phloyd · 02-21-2007, 11:35 PM

I have been experimenting with a number of broadcast streams and have found a couple of 'barriers' to compatibility with DVDit.

Bitrate: If the bitrate header is too high, DVDit will transcode the video, even if it is not the real peak bitrate. This can be fixed using Restream. An example is that HDNet Movies sets the bitrate header to 65 but that is not the real bitrate.

GOP Length: I gather that the GOP length should be no more than 24 frames for progressive and 30 frames for interlaced data on a BD. It is not clear where DVDit Pro HD draws the line but it is apparent that my ABC and NBC local broadcasts (28 frames in a GOP) and Showtime, Starz and Universal HD (29 frames in a GOP) are not acceptable to DVDit and it will transcode these streams. It is not clear to me how to get around this since I don't think it can be done without some additional I frames so some level of recoding is needed.

As a followup, I found that the VideoRedo tool has a function to reduce the GOP length on writing.

For PS and Elemental output, this can be accessed in the Options on the Save dialogue box.

I found that for Showtime HD data, the GOP of 29 frames could be fixed by setting a maximum of 17 frames. This resulted in one extra I frame being added per GOP. So it takes some time to recode that frame for every GOP - but I think it is worth it since it is not a complete transcoding.

Procoder Express has various encoding options depending on how you navigate the dialog boxes: you should be able to do MPEG2-HD at 1440x1080 with full control over other settings if you get to the right place. I'm looking into this now and will be testing output compatibility with Adobe CS3.

I have been on v6.3 [Build 631b04a] since late March 07. It is updated enough to recognize NFTS filesystems on volumes other than "C". I also use the "PS3 patch" so they play there as well as on my Sony BDP-S1. [The latter is a special version of the "MonteCarlo.dll" file]......

I have successfully burned a BD-RE disk and played it back on a Samsung BDP-1000 quite a few times now.

I used a Sony BWU-100 (with latest firmware update), and Cyberlink PowerProducer 3.7 and 4.1.

The Samsung BDP-1000 also has the latest firmware update.

Hope this is helpful,

So....does your PowerProducer 4.1 project have menus (BDMV) or just projects without menus (BDAV)? I'd moved on to DVDit Pro HD and haven't kept up on Cyberlink updates.
