Zkuste v nastavení Vegasu změnit hodnotu Dynamic RAM Preview na 0 a Maximum Number of renderig threads na 1.

1. Install Vegas to a newly created administrator profile. This will require uninstalling Vegas, creating a new user account, logging off the old user account, logging onto the newly created administrator account, and then installing and activating Vegas on the new administrator account. This allows the software to make the necessary changes needed to the registry.
2. Turn down Dynamic RAM Preview as this will free up memory for other tasks. This can be done by clicking Options > Preferences > Video tab. We recommend setting this value to 64MB for standard definition projects and 100MB for high definition projects.
3. Set the rendering threads to 1 on this same screen as a troubleshooting step.
4. Turning down the number of video thumbnails will also free up memory and is more noticable on larger projects. Click on Options > Preferences > Video tab and set the Show source frame numbers on event thumbnails to "None"
5. Within Windows, Go to Start > Run and type REGEDIT. Once in the registry, go to HKEY_CURRENT_USER\Software\ and find the Sony Media Software (or Sony Creative Software) folder. Right click on that folder and choose Permissions. Make sure Everyone, System, and your Windows username are all listed in the box at the top. If they are not there, add them. Make sure all of those entries have Full Control set to Allow. Click OK, close the registry, and try running the program again.
