@fr0sty Are you sure? Anthony says his AVC is 1920x1080 29.97 fps Interlaced and according to Wikipedia this is part of the Blu-ray specs?

I didn't see the interlaced part... yes, it does support 30fps interlaced.

The video I've been able to produce is acceptable, although still not quite as good due to the recompression and variable bit rate as compared to the original fixed bit rate of 38Mbps. However, it's the audio that I'm most looking for a solution to. The original 6912Kbps LPCM 6 channel audio I would like to preserve. So far the best I've been able to do is 448Kbps 6 channel with CyberLink's Power Director 17 (which still allows Dolby 5.1 encoding, can't believe they removed this in newer releases). So, I'm looking for software that will allow adding subtitles, while allowing me to preserve the best possible video and audio from my original video: 38Mbps; audio: 6912Kbps

Good information in there. Thanks! My video file is a rip from a non copy protected Blu-Ray disc. Just want to add subtitles and reproduce the Blu-Ray at the original quality. Seems like that shouldn't be so difficult. :-)

I still use DVD_A did some Blu-ray in the past (PAL) and it all worked well

Looks like Vegas Pro 19 might be able to do it if one could create a better video template. When I select to create a Blu-ray disc the selection of video templates is limited with maximum bit rate of 16Mbps. However, I see the audio can be Sony Wav64 which allows for the original 48,000Hz, 24 bit, 5.1 PCM audio to be selected for output. Any idea why the video templates don't go above 16 Mpbs, or anyone know of a way to create a template. I only see how to create video templates for rendering to output file, not for Blu-ray burning. Ugh.

I don't think VEGAS or DVDA will support burning 6 channel WAVs, unfortunately. TMPG Authoring Works looks like it does support it, however.

Maybe I think to simple, but as far I understand just a srt.file has to be added to the original bluray (which is not copy protected). So only the original bluray has to be re-authored in DVDA with the added subtitle file. So far I can see there's no need for re-encoding only re-authoring the bluray.

If you want a Blu-ray with basic but good quality 5.1 audio, you can do that using only VEGAS.

Just go to Tools / Burn Disc / Blu-ray Disc, there you can choose Sony AVC/MVC format for video with maximum bitrate up to 16mbps and AC3 5.1 audio with maximum rate of 448kbps or MPEG2 format for video with maximum bit rate up to 25mbps and AC3 5.1 audio with maximum rate of 448 kbps. See my screen recording below.

If you want a Blu-ray with advanced 5.1 audio with maximum quality, you will need to use the correct rendering templates in VEGAS to render the video and Install the free codec Voukoder to render the 5.1 audio. Voukoder for VEGAS can be downloaded from this link: https://www.voukoder.org/forum/thread/783-downloads-instructions/

In VEGAS Pro the Sony AVC/MVC format supports a maximum of 21mbps. MAGIX AVC/AAC format supports a maximum of 240mbps and the MPEG2 format supports a maximum of 80mbps. Voukoder codec supports a maximum of 640kbps for AC3 audio.

After that use professional Blu-ray authoring software to create your Blu-ray. For edits done in VEGAS Pro I recommend DVD Architect. DVD Architect supports Sony AVC/MVC, MAGIX AVC/AAC and MPEG2 formats for video and AC3 Pro for audio. The default for DVD architect is 18mbps for Video but it supports up to 40mbps and 448kbps for audio. See my screen recording below.

To add subtitles to Blu-ray you can create them directly in DVD Architect or if you prefer you can create them in VEGAS or other software and export them in .SUB format which is the format accepted by DVD Architect. In the example video below I created the subtitles in VEGAS and exported them to .SUB format to use in the DVD architect.

So once again I run into the same problem with these solutions. Either the software does the video quality up where I need it (38Mbps) or it does the audio quality up where I need it (24bit PCM 5.1 channel), but not both at the same time. I never dreamed it would be so difficult to take a simple high quality file, add subtitles, and burn it to a Blu-ray disc without losing any video or audio quality. So frustrating.

AFAIK, a multi-channel (poly) WAVE file is not an end-user format. There are other video file formats like MXF that embed PCM audio though.

I don't think VEGAS or DVDA will support burning 6 channel WAVs, unfortunately. TMPG Authoring Works looks like it does support it, however.

YES!!! Thank you! TMPG Authoring Works 6 did exactly what I needed. I was able to export my subtitles from Cyberlink Power Director, and import them into TMPG Authoring. The timing of random subtitles was off for some reason, but I just did a walk through of them making timing adjustments. I was then able to burn my Blu-Ray with lossless video at 35-40Mbps, and lossless audio with the original PCM 24bit 5.1 channel 6.9Mbps intact. It did give me a warning that my total bit rate was over the 45Mbps Blu-ray standard, but it let me do the burn and it played great in my Blu-ray player. I used the display setting while the disc was playing to confirm my video and audio was as expected. Awesome software! Thanks again for the advice!
