Rendering issues (once again)

This is a pretty common problem from what I remember in reading past posts, but unfortunately I've not seen anything that fully explains why Vegas does what it does.

Okay, first, you can see my computer specs in my profile, they are all up to date. I just shot some footage on my Panasonic AG-HMC40P in HD 1060-60i (1920x1080, 29.970 fps) I did a straight render with just a chroma key background as the only efx.

I "Rendered as" first to MainConcept MPEG as an .m2v file: I got Video but no audio!
Then I tried a render as XDCAM EX to an .MP4 file: And I got Audio but no video!
It would almost be amusing if I hadn't spent an hour rendering each one.

I just reinstalled Windows 7, because I didn't like Windows 8, and I also reinstalled Vegas 12, the latest version (Build 394)

Any ideas as to why this is occurring?

Thanks for any advice!
Lee

Leee: soak this in from another thread
Refer to thread Subject: RE: Renders Suddenly Started to Hang Reply by: videoITguy Date: 11/4/2012 4:40:10 PM

TVPC - what the test you completed tells us - is that given your system and the render settings that you used for "Quickie" your system is capable of working. Given the limitations that really huge projects with complex tracks might /or might not become a hassle.

Kill Internet acces by disconnecting your cable, then kill any virus program your running as you truly want your render machine isolated from this stuff. Turn screensaver function off and make sure you have no power plan running that allows drives, or other to sleep or hibernate. Some of that may go down into boot bios - check it!

Now, to Phase 2, Begin to parse up your project into separate saved mini-projects - say take the first 1/3 of the project, delete all events after third to end segment and try to render that into a file of its own. The the next third, and the final third. Make sure you save a backup of original project file, then save the parsed separate projects each, with unique names, and always reboot system before renders.

If your first 1/3 fails, parse that one into smaller chunk projects of say 50% each half - get to point to where you can truly isolate what hangs your original project.

Okay, thanks I'll give that test a try. But I'm still kind of confused. I assumed that this is a codec problem that wouldn't be affected by the length of the video. But, I'll give it a shot!

Just my 2c worth - apologies if this is too basic or you have already done this..

Looked at the MainConcept mpeg template. It appears if you click on the System tab at the bottom, there is a checkbox at the top - you can Save as separate elementary streams. If you check this, you SHOULD get a .m2v file (which does not have audio, obviously), AND a .mpa file. Leave the box unchecked and you SHOULD get a .mpg file, which contains both.
On the Bluray template the Include Audio Stream option (audio tab) is greyed out until you go to the System tab and uncheck the box as above - then you can come back and include audio.
That's all I can think of.

Ron is exactly right-on vis-a-vis the audio channel issue. This kind of interaction with the GUI is really throwing people off the course.

I just wanted to push my earlier post about how to deal with rendering projects - a lot of people are getting stung because they load an hour's worth and wonder why renders do crazy stuff if anything.
