Good morning, been working on a sizable project and had Sony Vegas Pro 11 crash.
I have autosave selected,and actually manually save about every five to Ten minutes.
I restarted program and it loads and opens... But the program freezes about 10 seconds after opening. Before all this started happening, I had imported a Camtasia MP4 file into Vegas... Which seemed to reap havoc with Sony Vegas operation, I went into computer and removed the MP4 file, but sorry to say this project still opens and freezes. I also tried opening a Vegas backup file..no go also The deadline is coming near to complete the project in a few days, so your input would be helpful thank you.

what other formats are on your timeline?

and what is your timeline properties?

Good morning Leslie, thanks for your prompt response...

AVC 1920x1080 MTS. Files ..... Downloaded from my Canon HFG 40...

Hi; have you tried to disable GPU preview?

Turn off timeline and program media video thumbnails. Transcode your screen capture using Handbrake. Open a different project to see if the program still freezes.

A good practice is to set the number of rendering threads to the number of logical cores visible by your system, and turning off Dynamic RAM preview if formats are causing instability. If you really are running into stability issues, turn your rendering threads to 1.

As other people have suggested, turn off any GPU acceleration in versions 11 and later if you're running into stability issues.

One option to try is to re-render your imported video into something else. I've personally had issues like this with video and images where Vegas for some odd strange crazy insane reason has an issue with a file and re-rendering the video into another format or image into a .png from a jpeg fixed the crashing. Also copy and paste your .veg file to another drive, I've had that fix a similar crashing before as well.

Turned off GPU acceleration.. For the moment this seems to be working ! Thank you all for your help!!

I'm glad to help you :-)
