"error occurred reason could not be determined"

Vegas Pro 9.0: (!)
"An error occurred while creating the media file MC1d.mp4.
The reason for the error could not be determined."

what does this mean? I'm rendering a 49 minute long file using MainConcept AVC. The shorter tests on the same material & codec worked fine. Any hints on what this means?

(some material was on an external USB drive- I'm wondering if that drive is the culprit)

EDIT: Well, it's repeatable. I tried again, and after another 4 hours, I got the same thing: another incomplete mp4 file exactly 4,947,654,334 bytes long, and Vegas halting with the above error message.

Are you using a FAT32 disk for the temp files or the output file?

(2^32) - 1 = 4 294 967 295

You can't make a file bigger than Gb in a FAT32 partition.

Thanks for the response. All the drives currently on the system are NTFS. I was wondering about the 4GB limit too, but the output file size went significantly above that limit. It is about 4.60 GB when it quits.

I recall a discussion about running out of RAM memory in some cases, but the process seems to hover around 750 MB in the Windows Task Manager, going up and down but never exceeding 800 MB, so that seems ok also.

Has anyone seen this "reason could not be determined" type of error? Shouldn't the program at least be able to tell me what module was active at the time of the fault, whatever it was?

I had the same problem. After one week reporting to SCS they confirmed that it exists with MainConcept AVC.
My tests showed:
Either render to <4GB (also on NTFS !!!) or without audio.

Ah-hah! That's good to know. I'm rendering it in smaller chunks now, which is working. Is there some document somewhere that lists all the currently-known issues with Vegas 9e? (I wasted a full day of trying to render the full thing, each time took about 5 hours to reach the failure point.)

Dream On !!! :-)

Please note the grin. I meant that in jest, only.

This is something, (I'm sure ! ) many of us have wished for.

Makes perfect logical sense too.

From our viewpoint anyway.

I'm not sure SCS would see it that way.
