Vegas 9.0a flatlining all M4A audio renders

2G wrote on 7/30/2009, 7:51 PM
I upgraded to 9.0a today. Now when I render any segment with an M4A (iTunes purchase) audio track, the render flatlines. And about half the time, after trying a render, no audio will play at all until I shut down Vegas and restart.

I even tried shutting down the system and doing a cold reboot just to be sure it wasn't some artifact left in memory causing the problem. Same thing.

Has anyone else seen this problem?

If the iTunes songs have DRM they are not compatible with Vegas. Make sure they are the DRM free version.

Burn them to a CD and rip from there.
This always works for me.

I know the difference between DRM m4p and m4a files. DRM files will not even drop on the timeline and never have. These were working projects in 9.0.

So I download and install a fixpack to Vegas and it breaks everything that was working five minutes earlier, and your recommendation is to change my process and start burning CDs. Am I supposed to go back and burn CDs for every song on every project that was working perfectly fine in Vegas 9.0? Amazing....

Maybe it's just me... but my first thought was that perhaps Sony ought to fix the defect that was introduced in 9.0a.

Another suggestion is to do what I did... blow away 9.0a and do a complete reinstall of 9.0. I can now render successfully.

2G, if you've been following this forum lately, you know that there have been a number of issues with the 9.0a release and you may have found another one.
I suggested burning to a CD if they were DRM files, not as a fix for your problem.
I'm at work right now but when I get home, I'll see if my 9.0a on my machine likes iTunes songs or not and let you know.

You didn't say what format you tried rendering to so I tried AVI, MPEG, WMV, MOV and MP4.
The only two that flatlined the audio were a 640x480 iPod template and a QT MOV encoded with the 3 Mbps Video template.
No custom templates were used, only the stock ones.

I am having what I believe is a similar issue with imported MP4 files. (h.264 video, aac audio at 64kbps)

If there is no existing .sfk file, 9.0a hangs trying to make one (the "generating peaks" thing stays at 0%). If there is an existing .sfk file created by an earlier version of Vegas, the import of the MP4 superficially "works" but the audio often doesn't play, renders to silence, etc. The video works fine.

After seeing this thread I'm going to try running the MP4 through ffmpeg with -vcodec copy and -acodec something else - anything else. mp3 would probably work.

...except that ffmpeg can't encode to mp3, only decode. dang.
