I've had this issue before, and I fixed it the same way that I may have just fixed it again, but it really isn't acceptable in any case, and I wanted to document it for anyone else having the problem, and see if this is a known thing, and/or if someone has some useful input.
The issue is that when I try and render anything (I mean any thing), and I click the Render button-- it doesn't matter what the output format is or where it's going-- Vegas hangs for around 7 minutes, then will crash, with one exception.
In running this bug down last time, I tried the simplest render I could think of: 15 seconds of generated text, rendered as image sequence-- and this also hung for about 7 minutes, but then rendered. After that, Render suddenly worked as expected-- any video/format.
I have no idea what's getting stuck, but I hooked my CLion debugger up to it while it was hung and I found that it was throwing an exception:
Exception: Exception 0x80000003 encountered at address 0x7ffa97c10860
The same workaround worked this time:
- Create a new project. I don't think settings matter at all.
- Create a new video track.
- Insert generated media (I use Text, and just leave everything default).
- I stretch the generated media out to 15 seconds, but it may not be necessary.
- Render As.. then choose "Image Sequence". I don't believe the format actually matters; I've done both TIFF and PNG.
- Point someplace for the images to go. (I send them to a folder that is emptied to trash every night).
- Hit Render.
- Wait... it will wait a long time, but then suddenly render. Interestingly, it counts the time that it was hung as render time.
After that, the next Render started immediately, and proceeded properly.
