BluRay bit rate

Mark-VanNostrand wrote on 6/29/2022, 8:33 AM

Old question, one that always seems to have an answer with a caveat. Is there a way to create a BluRay in DVD Architect (v5 or higher) with a total bit rate greater than 28?

Using Premiere Pro, rendering mpeg2 for BluRay, using 96/24 audio stream— DVDA won’t permit a total bit rate greater than 28. It says the ceiling is 40– but after 28, it will always recompress— which defeats the purpose. Total bit rate of 28 is still far, far better than DVD— but the allure of 36-40 total bit rate is strong.

Is there a secret button I’m forgetting to push? Thoughts appreciated.

There is still a market for physical media out there, and it’s unfortunate there are no professional products (except prohibitively expensive ones) left to do this. DVDA had such potential to be that product, then they ended the product. It’s still not bad at all, but is falling behind the current technology rapidly.

Are you rendering the video/audio as one mpeg file? I just rendered a video mpeg only at min 30 and max 40 bitrate and DVDA accepted it fine. It is best to render audio and video as separate files.

I render as separate files. And the only way it will accept creating the BluRay ISO is if I ensure the combined video and audio bit rates of each element (media files, menu, etc) are under 28. Note that I don’t use Vegas, but Premiere Pro to render into mpeg2.

What platform are you using to render? Can you share the step by step flow that you have success with? Thanks.

I use Vegas Pro v19 with Mainconcept MPEG encoding. I set it for VBR with 30 minimum and 40 maximum. Mediainfo reports it as being a bitrate of 30.1 with a max of 40. DVDA reports it as being 30.48 with no recompression required.

@Mark-VanNostrand @DMT3 Is there a reason you are both rendering to mpeg-2 and not mpeg-4/AVC/H264?

I like MPEG, it renders much faster and gives me all of the quality I need.

I would like to use mpeg4/h.264, but DVDA does not accept it rendered from Premiere Pro— in my attempts. I recall reading something about DVDA requiring Vegas rendering for the higher bit rates (above 28) and also for h.264. Can’t swear to that, though.

Eric- what platform and rendering have you used for this?

For the video stream I render an AVC video stream from Vegas Movie Studio 17 Platinum using either:

MAGIX AVC/AAC MP4 - Blu-ray 1920x1080 50i with Encode mode Mainconcept AVC. The default has Max bps 40,000,000 Average 25,000,000. My personal preference is to customise this to CBR 20,000,000, or

Sony AVC/MVC - Blu-ray 1920x1080-50i with the bitrate customised to 21,999,616 (max). This figure is a max figure and my render average is usually around 18,000,000.

Both give good results and accepted by DVDA7.

Good info, thanks to both of you. For whatever reason, I am neither able to exceed a bit rate of 28,000,000, nor able to use h.264 mpeg4. Am not unhappy with the uncompressed video and audio results I get at combined 27,999,998— it is quite nice. But the source footage would support much higher bit rates.

Thanks again, have a great week.

@Mark-VanNostrand If you are producing burnt discs these threads may be a worthwhile read:

Eric- thanks, more good info. It does seem that this bit rate dilemma still has a cloud of confusion surrounding it. If the one post is correct, and BluRay can only be “pressed” to the higher bit rates, but not “burned”, then this could a futile exercise.

Regardless, appreciate the responses. Will continue to experiment— heck it took a lot of experimenting to achieve a >23,000,000 96/24 BluRay without recompression. And the demand for physical media— though still out there, is still fading.

Cheers all.
