Ridiculous Times For Blu-ray Preparation in Ver. 6

Hey guys,

I decided to finally switch to Sony Vegas so I can natively edit 4K footage captured by my PXW-Z100, and I'm encountering a problem with burning Blu-rays.

I've ensured that the video and audio tracks were 100% compliant (1920x1080 Blu-ray compliant 22mbps AVC files), paired with AC-3 audio. I'm trying to create a BR-DL image, containing just shy of 5 hours of footage. Now, Architect Pro is saying that it is "Preparing compilation", going through all of the footage one by one with an estimated completion time of 78 HOURS! Even my prosumer editor that I was using prior to this produced Blu-rays faster than this.

I've been frantically searching for a solution, and apparently, an MPEG-2 encoded Blu-ray should only take a matter of minutes to prepare (though the MPEG-2 codec is less efficient, space-wise than AVC), but seeing as my footage took long enough to render out in AVC as it is, it would be more sensible to just wait out the 80+ hours for the Blu-ray than to render all of the footage *again* in MPEG-2.

Is there a solution or is DVD Architect Pro just horribly inefficient?

Cheers.

Are you really trying to fit 5 hours of high-def video on a single BluRay disc?

Standard BluRays hold about 2 hours of video. A dual-layer disc holds about twice that.

Your workflow is correct, in that you're providing DVD Architect with optimized video. However, because you're giving it more video than can fit at full resolution onto a disc, you're asking it to re-compress your optimized video -- which kind of nullifies the fact that you've provided it with an optimized video format.

If you give DVD Arch a 2-hour video in that format, it will transcode and spit out your disc in about 30 seconds.

Are you serious? I've never managed to burn any kind of disc in 30 secs, never mind prepare and burn one.

No Steve, is just playing on words. It certainly depends on what you want out of the results.

I have burned Blu-ray exclusively on a server farm with high-power capacity servers and DVDAPro for the last seven years. I always submit compliant streams of Mainconcept Mpg2 video and AC3-Pro or PCM audio. I want output of the highest Blu-ray quality matching Hollywood -
this means - a one hour disc will prepare in about six hours and burn copies in about 40 minutes each.

You're right. It does take a bit longer to actually BURN the disc.

But when I use DVD-ready MPEGs as my source files, DVD Architect transcodes the prepared files in under a minute.

The physical burning of a disc can take a bit longer. But, if your video does not need to be re-encoded or re-compressed, the only thing the program has to do is convert your menus to disc-ready, which in most cases takes only a few seconds.

Fair enough, but this thread is about Blu-rays. Preparing those takes a great deal longer.

But still only a few mins.....as long as the only render for DVDA is the menu/s

PREPARING the folders can be done in a few minutes.
Or, it can take over a day if the media needs to be re-rendered

BURNING the physical media will take the time it takes.
