Burning BluRay Image Errors

jrazz wrote on 5/27/2008, 6:59 PM

So far I have attempted to burn footage to a BluRay Disc utilizing Vegas pro 8.0b's timeline burn to bluray feature. It failed over 8 times and sometimes it would give an error message that gave an exception but the majority of the time it gave an error that had no details as it occurred unexpectedly according to Vegas.

This would occur at different times during the process. Sometimes it would ocurr during the rendering, sometimes during the compilation, sometimes during the preparing image. So, there was no way to say it was a certain portion of the timeline that caused this problem. I also tried this on 2 systems with the same sets of errors being displayed. I also found that I did have an event that I placed a duplicate above the event with the opacity set to 60% and with Velvet Matter FX applied to the event below (this caused only one core to be utilized and often ended the encode prematurely for some reason by just shutting down Vegas- although, the encode to mpeg-2 DVD Architect Wide Screen template worked just fine). So I removed the opacity and the effect (one at a time until the problem was gone).

I tried with errors 3 different ways with a 1440x1080x32 29.97i timeline: 1. I had the original edit on the timeline and attempted to make a BluRay disc. 2. I encoded utlizing smart render to encode to M2T and then attempted a BluRay disc. 3. I encoded out to Cineform avi and encountered an error while attempting a BluRay disc.

So, one error gave me a hint. In the error code it mentioned the audio and the wav format (I think the Sony Wav 64 is the default audio for BluRay authoring from the timeline). So, I changed it to Dolby AC3 and burned the disc from Cineform Avi without issue.

I don't know if anybody else has encountered this issue but if you have, try changing your audio to Dolby.

Also, why so many steps in producing BluRay? If I already have a perfectly acceptable M2T file, why must it render again? Then compile then image then burn? Why can't the rendering be skipped?

j razz,

Good point about the audio. I know that stereo vs surround can also be an issue when rendering out as well.

But your comment, "Also, why so many steps in producing BluRay? If I already have a perfectly acceptable M2T file, why must it render again? Then compile then image then burn? Why can't the rendering be skipped?" raises some issues for me as well.

The toolbar workflow "Burn Disc - Blu-Ray Disc . . ." gives me a render, compile, image, burn. I wind up with my *.m2t timeline files (residing on D) disappearing into these intermediate steps and emerging on my J drive as an *.iso. BTW, the PS3 plays my DVD+R HD burns beautifully.

I wonder, where do those intermediate files reside? Do they accumulate? Do I need to clean them up over time?

If I intend to go to a Blu-Ray burner and media if and when Sony offers Blu-Ray authoring, should I assume that I should render out an *.m2t file and stash it away so that I could then combine with other such and author a genuine, menu-driven Blu-Ray disc down the road?

Sorry I haven't (can't) answered your question. But I think we're both scratching our heads over this timeline burn workflow.

I haven't tried it from the timeline with a BR disc, but burning HD-BR on a standard DVD I only get re-renders from the m2t when there is an effect, a disslove or other transistion. Otherwise, I get a message in the preview window during the preparation of something to the effect "Re-render not needed".

I'm limiting edits to cuts, crossfades, and cut to black. No other video FX et al applied, although I've had to boost the audio via "normalize." I still don't get the workflow not the file generation in prep for the ^.iso.

The MPEG audio contained in an HDV .M2T file is not a recognized audio format for Blu-Ray discs. However, the MPEG2 video portion of an HDV file is completely Blu-Ray compatible.

I use Encore to author Blu-Ray discs. I edit HDV in Vegas and will often just smart render the final product to a finished HDV file. I then render the audio out of Vegas as a .WAV file if it's a stereo project in either 16 or 24 bits depending on the desired audio quality or .AC3 if I'm working in 5.1. I then use VideoReDo to demux the HDV file into separate .M2V and .MPA components. I just delete the .MPA file. I then take the .M2V and the .WAV or .AC3 files into Encore and author it up. Works great.

This probably won't help, but I'll tell you what's worked for me. Granted, the BDs I've burned so far have all been test discs with running times of around 10-15 minutes, but it may help a little. Basically, I'm taking AVCHD footage from my camera (Canon HF100) and performing a few rudimentary edits (dissolves, cuts, adding titles, etc. - nothing terribly fancy.) When I choose Burn Disc, I use the MainConcept MPEG-2 encoder set to the Blu-ray 1920x1080-60i, 25 Mbps video stream template. For audio, I used PCM (WAV64 - 16/48.) All of the test discs have played fine in my 1st Gen Panasonic BD player (I'm using a BD-RE - just in case) and the footage looks great. I was afraid that going to MPEG-2 might introduce some artifacts, but there were none that I could see.

I'm looking forward to the June updates, which should give us real BD authoring in DVD-A and (probably) support for 1920x1080 AVC encodes.
