Burn BluRay from timeline hangs

otspbob wrote on 11/16/2007, 7:41 AM

I have the latest build of V8a on a WinXP PC with 3.4gHz Pentium D and 2GB of RAM. I successfully rendered and burned a BluRay disc of a short WMVHD video clip yesterday, so then I tried to do the same with a complete HDV project (except that I chose to render an .iso image without burning). When I left last night, the rendering was about 50% complete after about 5 hours of rendering. This morning, the rendering progress bar was replaced with one that reads "preparing compilation." The "progress" has been stuck at 0% ever since I got here an hour ago. Should I give up and cancel the process? SOMETHING was created and rendered, because the hard drive now has 20 less GBs of space. I would just hate to lose it all if there's a way to salvage it. The destination folder now has an .iso file that shows that it was "modified" a few hours ago (presumably when the render was done), yet the file size is 0kb. I searched the whole PC for any large file that was created in the last two days but found nothing, not even a temporary file. Is the "preparing compilation" hang a known issue?

Under "Preferences/Options settings" you have an assigned temporary files folder.
Look in that folder for any subfolders that begin with a tile ~
I think all the temp files are in that sub-directory along with other directories & files, I don't think you can re-use the files.

OK, this time, instead of burning a BluRay disc of an entire project from the timeline, I tried burning one from a single WMV-HD file of that same project - render only, MPG, 1440x1080 60i, 25mbps, AAC, keep chapter markers. A 4-min. highlight video from a WMV-HD file worked yesterday, so I tried the full 80-min. video today. It rendered in about 3 hours, then went through the "preparing compilation" step in about one hour, then returned to 0% on the "preparing compilation" progress bar, and now (just like last night's project) it's been stuck there for the last two hours. For good measure, I tried the same with a 1-min WMVHD clip with the exact same settings and a few chapter markers, and I watched as it prepared the .iso file perfectly to completion. So the only difference between these two tests is the length of the clip. Can anyone speak to this?

Somehow I didn't realize until just now that by owning V8 Pro, I got 60 days of phone tech support! How awesome is that??? And I got my answer, too. Whatever the estimated size of the rendered file will be, the temporary folder needs to have 4-5 times as much space as that. It's a bug that they're fixing. I had been trying to render a 17GB file to a drive with 45GBs of space - not enough. I went into Preferences and switched the temp folder from the default to a drive with over 100GBs of space. Presto!

I've been putting the assigned ISO file location on a drive other than my assigned temporary directory I have Vegas assigned to write the ISO file to.
It's also faster because building occurs in the temp directory.
My files haven't been that large, only burning dvd's.

Here's an answer and a question...

I had a freezing problem as above on a 75 minute project.
It contains mixed media: SD, M2t direct from camera and various 1080i pre-renders.
It would get about 55% done and simply freeze.

So I pre-rendered the entire movie to a 1080i intermediate and that rendered w/o any problem. (About 6hrs for the 1080i pre-render and 3 1/2 hrs for the Blu-Ray render on a Q6600 with SATA RAID 0 drives).

Now the question; do I lose any HD quality by implementing this pre-render?

I would say that you aren't losing any appreciable quality, but you have lost the time advantage of rendering from the timeline over just using another dedicated Blu-ray authoring program.

Urghhhh... after several hours of rendering a 1h:30mins HDV project into Bluray, Vegas just stopped responding at the very beginning of "Preparing compilation" (after having rendered the video, audio, and completing the first compilation). Why the second comiplation!? Then it just crashed, with the following error message:

When I confirmed the error message with OK, all the prerendered files in my Vegas temp folder were removed.... What could be the reason?

I've checked and there is some 400GB free space in the temporary area, but yes, only some 40 GB on the target partition for the image file (estimated ca. 20GB) - could this be the reason? But my impression from the solution found earlier in this thread was it was the temp and not target area that had to be so much greater...

Or BOTH?

I would appreciate somebody confirming the reason of the BluRay rendering failure before I try another, several hours attemp....TIA.
