Best Blu Ray settings for HI DEF with CC

I am producing a show for sat uplink and the affiliates want to have blu ray disc backup. I want to keep the highest possible quality that will play on any blu ray player. I must be able to pass FCC closed captioning in the blu ray copies I send out.

How do I render for DVDArchitect so thay my blu ray disc meets these requirements and the highest possible quality?

Assuming the video you're putting into DVD Architect is of the optimal format and size (1440x1080 MPEG2/M2T) and you aren't putting more on the disc than it can hold (about 2 hours fits on a standard BluRay), the program will automatically give you the highest quality output possible.

In fact, tweaking the settings (such as increasing the bitrate manually) may prove counter-productive.

Just give it great, optimized source video and it will give you a great BluRay disc.

Interesting question. Does he have to do anything special to keep line 21 closed captions when authoring a BD? I remember trying a Vegas plug that helped with thus, but am not recalling the exact name right now.

The WikiPedia article on CC says:

HD DVD and Blu-ray disc media cannot carry Line 21 closed captioning due to the design of High-Definition Multimedia Interface (HDMI) specifications that were designed to replace older analog and digital standards, such as VGA, S-Video, and DVI. Both Blu-ray disc and HD DVD can use either PNG bitmap subtitles or 'advanced subtitles' to carry SDH type subtitling, the latter being an XML based textual format which includes font, styling and positioning information as well as a unicode representation of the text. Advanced subtitling can also include additional media accessibility features such as "descriptive audio".

Actually, to "Wikipedia", CC info can be, and is, carried in the signal. HDMI does not pass through that signal as of yet so that part is correct. But the info *is* there. FOr example if you have a cbale box it has a built in CC decoder. Watch and HD braodcast, turn on CLosed Cpationing and there it is - even with HDMI. The decoding must take pace before the HDMI run to the Monitor/TV

This is a tricky quesiton at the head end because too many people now, and I have seen this in these forums as well, say there is no such thing a Closed Captions anymore because you simply can't do it and/or that DVD's simply never caryy Captioning. The fact still is that, if you plan on doing anything for the United States, it is a law the material broadcast must carry the data. I was one of the people who kept "pushing" Sonic Foundry/Sony to add support - which they finally, sort of/kind of have done.

This question of how to add the CC info is somewhat of an easy one - you add them in Vegas and render out for DVD-A. As long as no re-rendering is done all should be fine. The MainConcept codec, which Vegas uses, has always had the abilty to pass through CC data but for whatever reason Sony never chose to activate that switch until recently.

Try a test - create a new project in Vegas, set it to your specs for your disk. Create some captions and render out using one of the DVD-A templates. Create your DVD-A project and 'render" it. Now bring the resulting m2ts file back into Vegas. If the caption are still there you will see Vegas extract them and they will be "tied" to the video.
