Vegas Pro 9, still having problems with AVCHD rendering at 1080i…
I have a Sony SR-11 video camera. It shoots at 1920x1080i in AVCHD.
In Vegas 8, I couldn’t even render to 1920x1080i…it would start working…and instead of rendering, the estimated time would go up and up and it would never finish. I could render to 720p fine…but 1080i AVCHD was out of the question.
Now onto Vegas 9…and things are improving, if only slightly. Now it renders at 1080i perfect. For a 3 minute video it took about 6 minutes on my quadcore. When I go to watch the video it appears perfectly fine…until we get to the end. On my popcorn hour it gets to the end with about 5 seconds left…and the video freezes while the audio continues. Then when the audio is done, the video finishes in silence. On the PS3 it was a little different. Again it played fine most of the way through…but with about 30 seconds left, the video started to stutter and lose audio sync. It played the whole way through without actually freezing, but the end was messed up. This happened with two different rendered files.
To make matters more confusing, I just tried them on the PC using Haali and CoreAVC, and they played fine all the way through to the end. Only strange thing was skipping around. If I skipped to the end with less than 10 seconds left, I got no audio. I skipped to 11 seconds left, and I got audio the rest of the way. What the heck?
Again, I’m rendering to the AVCHD 1920x1080i60 default profile. This is the 32-bit version on XP. I’d love to be able and work on all the family video I have from the last year or so…but I’m not putting in the effort until I know the files are being rendered properly. Any ideas?
Thanks in advance!

The .veg file I was using was created in Vegas Pro 8…so just for the heck of it I started a brand new timeline and did a new render…and so far it seems to work great. I don’t want to re-edit my son’s 1st birthday video…but if it works, then it’s worth it.
Gonna try with a much longer video and see how that renders. Thanks!

Tried a 7 minute render on a fresh timeline, couple transitions, nothing fancy. Rendered without an error, but once again, the video froze up with about 15 seconds left while the audio continued.

Are you using v9 or v9a?
vp9a corrects some rendering errors with avchd

Hi Norman. Initially I was on 9.0…but I upgraded to 9.0a, and the results are identical. The fact that it can render without crashing the program is good, but still not all there.
I need to do a test, but I think this only happens with clips that are longer than a few minutes. I did a test with a short clip…maybe 1 min, and it was fine. So that makes me wonder if it’s a memory problem, where these longer clips are making it choke at the end. When I get a chance I’ll do a test in 30 second intervals and see what I can find.
The one thing I haven’t been able to determine though, is can anyone else render to 1080i AVCHD successfully?

Can you run diagnostics on your RAM and swap file (hdd)?

Dunno. All my renders so far are to .avi and Internet 30p

I have rendered several projects to 1080i and 1080 30p with no problem on a I7 with 6gb. with vegas 9a. My problem was burning to dvd or blu ray and found I had to slow the dvd burn to 8x and 2x on the blu ray

I can run diagnostics on that stuff….but I don’t think my machine is the problem. Been running fine for a very long time. If there’s anything wrong, it’s with how Vegas handles my memory.

Nathan, Vegas has been handling your memory fine for a very long time; yet now all of a sudden it goes belly-up…but nothing has changed with your machine?
You can do what you want, but why not just give F12 a whirl? Your memory is probably just 100% fine…but then you will know.

Just a recap on the vegas problems I’m having.
I have been successfully rendering to 720p AVC/mp4s for vimeo with zero problems. The only time I have problems are rendering to AVCHD at 1920x1080i in an m2ts container (this is a default profile in Vegas 9). In Vegas 8, the program would full on crash. In Vegas 9, it renders successfully, but the resulting file is not playing back well in several players (one of which is a PS3, which is very disconcerting). Even playing it back through software on my PC, there is odd artifacting at the end of the file.
I’ll check out the memory though. What do I do with F12?

Since you have 6gb of ram, I assume you’re using 64-bit Vegas? I’m running 3gb of ram on 32-bit vegas on Win XP.
I can successfully render, but the resulting file is not playing back correctly.
