How much free, defragmented space is on your C drive?

Are you editing your video on your C drive or to a second hard drive? If to a second hard drive, have you ensured that it is formatted NTFS and not FAT32 (as drives come from the factory)? FA32 drives have a file size limitation that can choke the production of larger video files.

The problem you describe is often caused by a lack of large, free, defragmented chunks of work and write space.

I don't understand some of the questions, but here's what I know:

I rendered the three clips using Sony AVC, template Blu-ray 1920x1080-60, 16Mbps video stream and AC3 for audio.

I don't know what "Match media" is.

I'm using DVDA 5.2 to prepare the Blu-ray disc for burning. It does not attempt to recompress.

The preparation disc is not the C: drive, it's another 1TB drive that has about 600GB of free space. I defraggged it before I started this DVDA session,.

Thanks for the help.

All the drives in my system are formatted as NTFS.

THe machine is about 2 1/2 years old. It's a quad core with 8G of memory.

You assume that since you are writing to a disc that that has to be the cause of the error. How's the free space on the drive with the TEMP folders?(Typically the C drive).

Also, what drive are you writing the DVD prep files to? Also defaults to "C:".

The C: drive has 520GB free.

The DVD Prep files are being written to the e: drive, which has 245 G free.

Anyone?

Here are a few ideas ~

I rendered the three clips using Sony AVC, template Blu-ray 1920x1080-60, 16Mbps video stream and AC3 for audio.

I don't know what "Match media" is.

Choose File/Properties. The line of the Video tab has an option called Template. Look to the far right and you will see a Filmstrip looking icon (Vegas 10) or Folder icon (various other versions). Hover your mouse over the icon and it should say "Match Media Settings."

If you click on this icon, Vegas prompts you to choose a clip that best represents the media in your project. Note it doesn't have to be an actual clip in your project, just a clip that represents the media. After you select a clip, note the template and other variables int he Video tab may change to better match that clip.

I'm using DVDA 5.2 to prepare the Blu-ray disc for burning. It does not attempt to recompress.

If DVD-A does not want to recompress, the chances are good that you have rendered your projects from Vegas in a format that meets the standard for DVD-A without recompression. That sounds like a dumb statement, but it is possible to render from Vegas with recompresion, and then render again from DVD-A with recompression. We want to avoid recompression as much as possible because typically that means a loss of quality.

The preparation disc is not the C: drive, it's another 1TB drive that has about 600GB of free space. I defraggged it before I started this DVDA session,.

After I render from Vegas in a format suitable for DVD-A, my Video and Audio files are not on an external drive. Maybe try moving your rendered files to an internal drive before rendering in DVD-A?

Some Vegas Rendering Suggestions. If you haven't already done so, go back and select "Match Media Settings" in your File/Properties/Video tab. Now choose File/Render As.

Choose Mainconcept MPEG-2 as your Save-As Type. Click the Template box and choose any Blu-Ray template that has an ( = ) sign beside it. That is the template that is best for your video based on the Match Media Settings you indicated and the Mainconcept MPEG-2 Save-As Type. Note if you select other Save-As types, the Templates with the ( = ) equals signs will change.

You can double check the required DVD-A format for your kind of media by going to Help in DVD-A and searching for "Recompression, Avoiding." There is a discussion about what templates and Save-As types to choose in case I have given you some bad direction above.

One other idea. Once you are ready to burn your disk in DVD-A, choose File/Optimize Disk and review the warning messages. That may give you some ideas on where things are failing.

Using the above approach, I am able to burn Blu-ray format disks on DVDs and watch them in my Blu-ray player. I do this because I don't have a Blu-ray burner right now. But that is beside the point because the workflow is the same up to the point of telling DVD-A that I'm using a DVD versus a BD disk. (You may already know this, but you can put your Blu-ray project on a DVD, however a DVD is much smaller than a BD so the project must be small. Not every Blu-ray player will play these disks. My player is new and it plays these disks. Your player may not play them.)

I hope some of that helps and you have success with your disk.

Maybe the tutorial will identify something that you are missing in the render and creation process.

I had a similar issue when I tried to burn my first bd-re. Few minutes of activity then file write error.

For me it turned out that I had to update the firmware in my bluray writer. I was using an LG drive from 2006 with a driver from the same year. The latest firmware update added support for newer bd-re disks. After the firmware update I have had no issues. with DVDA 5.2 and bd-re creation.

Hope this helps.
