Muxing with Streamclip because Toast does a poor job
on Mar 27, 2009 at 4:54:10 pm

Hi All,
I am preparing a BD-5 of a project that is about 15 minutes shot on Varicam.
I have made good H264 and ac3 files. I'm trying to use streamclip to mux it so I can make the disc.
I have Toast 9 but it muxes poorly and the results are unusable.
From what I read toast 10 is no better.
I prefer to stay in H264 because I can use lower data rate safer on BD5.
So I'm trying Streamclip.

In streamclip I open the H264, sound is there from the ac3 file and it all plays well.
All the convert to options (i want to go to TS) are grey.
I'm probably missing something simple, but I'm stumped.
Any suggestions?
Any other program that can mux this without forking over the $600 upgrade that gets me to Adobe Encore?
Otherwise anyone out there who can mux it for me?
I'll pay some reasonable amount.


Thanks,
Kevin

BD has very tight requirements for H264 (AVC) -- it's nothing like encoding an mpeg2. Chances are your streams are not up to spec and will not be muxable.

Hi Max,
Thanks for that hint.
Sounds like I won't likely succeed in my H264 quest.
Is there somewhere I can read up on the requirement for the H264 file?
Or failing that, is there anywhere I can go for a bare bones no menu autoplay Blu-Ray from my 15 minute DVCPro File?
I'll try theMPEG2, but my experience was if I got a data rate low enough to play from a BD5, the quality was not great.

Thanks,
Kevin

BD H264 requirements are in the BD spec book, but you're not likely to get a hold of it. You either have to outsource to specialized BD AVC encoder (Cinema Craft, Blu-code, Cinevision or Nexcode) or an encoder with "legal" presets like Inlet's Fathom. You can also use X264 which is free and does a very good job. Do a search on how to configure it for BD.

Hi Max,
Thanks for the info, I'll check out x264.
Also experimenting to see how high a data rate I can put MPEG2 on BD5.

Thanks,
Kevin
