If VEGAS Pro is crashing or behaving strangely, there are many things you can try to troubleshoot it. If the software hangs during rendering then see this post.
1. INSTALL THE LATEST UPDATE
Make sure you are running the latest update of the version of VEGAS Pro that you wish to install, unless you specifically need an earlier release. See "Where can I download VEGAS Pro?"
2. SYSTEM REQUIREMENTS
Check that your computer meets the system requirements. For the latest version of VEGAS Pro, the system requirements are here. Note that VEGAS Pro is only officially supported if it's installed on the same drive as your operating system.
3. DISABLE GPU ACCELERATION
GPU acceleration is often responsible for stability problems in VEGAS. Try turning it off in "Preferences" > "Video" > "GPU acceleration of video processing". You will need to restart VEGAS afterwards:
If you are rendering with the Sony AVC/MVC codec, try turning GPU acceleration off in "Render As" > "Sony AVC/MVC" > "Customize Template" > "Encode mode":
If you are rendering with the MainConcept AVC/MVC codec, try turning GPU acceleration off in "Render As" > "MainConcept AVC/MVC" > "Customize Template" > "Encode mode":
If disabling GPU acceleration solves your problem then try updating or rolling back your graphics card's driver. See the section below.
4. WINDOWS UPDATE
Search for Windows Update on your system. This can be done in the Windows Start menu or by pressing the WINDOWS+Q keys on Windows 8.1 and 10. Let Windows check for updates for the system and install any that are available. Restart your machine to finish the process.
Follow any prompts to reboot, and be patient with the update process, which can take a long time. If you have problems, consult the Windows Update FAQ. For Windows 10 you can use this Windows Update Troubleshooter.
5. DISABLE ANTI-VIRUS SOFTWARE
If you run anti-virus software, or some other utility that scans for adware/spyware, try temporarily disabling the software. You may also add the program executable file (e.g. C:\Program Files\VEGAS\VEGAS Pro 15.0\vegas150.exe) to the exception list for the anti-virus software.
6. CLEAN BOOT
Try a clean boot of your system so Windows will start with a minimal set of drivers and startup programs. See How to perform a clean boot in Windows.
7. REMOVE PERIPHERAL HARDWARE
Try disconnecting USB devices, dongles and other peripherals from the system. If that solves your problem, replace them one by one while testing VEGAS until you find the one that causes the problem. Then try updating or rolling back its driver.
8. UPDATE HARDWARE DRIVERS
Update your system's drivers and firmware from the manufacturer's website(s). Drivers installed by Windows Update can cause problems. In particular, try updating or rolling back your graphics card driver from the manufacturer's website or from the NVIDIA or AMD website. Display Driver Uninstaller can help with a clean uninstall. (more about graphics cards here). Also look for updates to your motherboard's BIOS, chipset software and drivers for your sound card, DVD drive, network adapter and peripherals.
9. RESET VEGAS PRO TO DEFAULT SETTINGS
Reset VEGAS Pro to default settings by pressing CTRL+SHIFT on your keyboard while double-clicking the program's icon to launch it. More information here.
10. DISABLE PLUGINS
Try disabling 3rd-party plugins, especially old ones, by renaming the folders they reside in, or moving them to a location where VEGAS won't find them, or by uninstalling them.
Include OFX plugins which may be in these example locations:
- C:\Program Files\Common Files\OFX
- C:\Program Files\VEGAS\VEGAS Pro 15.0\OFX Video Plug-Ins
- C:\Program Files\VEGAS\VEGAS Pro 14.0\OFX Video Plug-Ins
- C:\Program Files\Sony\Vegas Pro 13.0\OFX Video Plug-Ins
Also include application extensions which may be in these example locations:
- C:\ProgramData\VEGAS Pro\Application Extensions
...Documents\Vegas Application Extensions
If this solves the problem, then re-enable the plugins one by one until you find the culprit.
11. USE VEGAS-FRIENDLY FORMATS
If you have a choice, use source-media formats that work well with VEGAS. For example Sony formats such as XAVC Intra and XDCAM work well with Vegas, and MPEG2 and AVC are well supported. This post lists some formats that don't work well and some converting applications that can be used to transcode media.
12. SET DYNAMIC RAM PREVIEW MAX TO ZERO
Some users have been able to avoid crashes or complete troublesome renders by setting the Dynamic RAM Preview max (MB) value to zero.
Note that if you leave this setting at zero, you will no longer be able to build dynamic RAM previews, and it might adversely affect VEGAS Pro's performance in other ways such as how smoothly your timeline plays.
13. MICROSOFT .NET FRAMEWORK
Try repairing all versions Microsoft .NET Framework on your system.
Go to the Windows Control Panel and open "Programs and Features". Click each version of Microsoft .NET Framework then "Uninstall" then "Repair". Windows 7 users can use the .NET Framework Repair Tool.
If that doesn't help then you can try removing and reinstalling them. You can download .NET Framework installers from here.
See this article for more help and other options for repairing .NET Framework.
Although .NET Framework 3.5 is not required for VEGAS Pro 12, 13, 14 or 15, it might be required for some legacy applications or plugins, but it is not automatically installed with Windows 8, Windows 8.1 or Windows 10. See this article for help installing/enabling it.
14. MICROSOFT VISUAL C++
Try repairing all versions of Microsoft Visual C++ on your system.
Go to the Windows Control Panel and open "Programs and Features". Click each version of Microsoft Visual C++ then "Uninstall" then "Repair".
If that doesn't help then you can try removing and reinstalling them. You can download Visual C++ installers from here.
Here are some Visual C++ redistributables associated with various applications. Plugins or other features can sometimes require portions of earlier redistributables.
Visual Studio 2012 Redistributable (x64 and x86):
- VEGAS Pro 13
- VEGAS Movie Studio 13
Visual Studio 2008 Redistributable:
- DVD Architect 5 & 6
- Sound Forge 10 & 11
- ACID Music Studio 10
Visual Studio 2005 Redistributable:
- ACID Pro 7
- CD Architect 5.2
15. UNINSTALL/UPDATE QUICKTIME
Quicktime is no longer installed automatically with VEGAS. VEGAS Pro 14 and later versions now read ProRes formats natively, and some other .MOV files such as those containing H.264 (AVC) video will also be read natively by VEGAS. However many Quicktime formats still require Quicktime. Try uinstalling it if you don't need it, or updating to the latest version from this link. Old versions of Sony Vegas Pro such as 10.0 required Quicktime 7.6.2.
16. COMPATIBILITY MODE
Try running the software in Windows Compatibility Mode. Right click on the program's icon and choose "Properties" > "Compatibility". Check "Run this program in compatibility mode for:" and choose progressively older operating systems.
17. CLEAR TEMPORARY FILES FOLDER
Try clearing your temporary files folder. This involves some risk (read that post in full) and should be one of your last resorts.
18. DISABLE SO4COMPOUNDPLUG (VP15 AVC / XAVC-S)
VEGAS PRO 15 has a new decoder for XAVC-S files and some AVC files. This codec may cause various issues such as slow loading, stuttering playback, and high memory usage leading to a crash. If your footage is opened by this "so4compoundplug" decoder then you can try disabling it. See this post for more information. If that doesn't help then re-enable it for wider format support.
19. DISABLE QSV
If you have an Intel CPU with integrated Intel graphics you may experience crashes or hangs, for example:
- Crash or hang when you click Render As.
- Crash when you play AVC media (decoded by so4compoundplug).
- Hang when you render Intel HEVC.
In such cases, try disabling QSV. In VEGAS Pro 15 build 361 and later, this can be done with Options > Preferences > General > Enable QSV Encoding and Decoding (where available):
In previous versions, you can disable Intel HD graphics in the Windows Device Manager:
Disabling the other (discrete) display adapter (e.g. AMD or NVIDIA) instead, if you have one, may also help, but the computer's performance may suffer.
QSV can also be disabled just for the Intel HEVC renderer, to improve quality (at the expense of speed) and/or stability:
20. REINSTALL VEGAS PRO
If VEGAS Pro still won't start, uninstall it using "Control Panel" > "Programs and Features", reboot your computer, reinstall it, and see if it will start. See Where can I download VEGAS Pro? to find the correct installer.
When VEGAS Pro is uninstalled, some folders and Windows registry entries are left behind. You may have a better chance of success if you do a clean uninstall and reinstall, which will remove these (along with your settings).
For (MAGIX) VEGAS Pro 13 build 543 or later, follow these instructions.
Cleaning your registry (see below) between uninstalling and reinstalling can help clean up remaining redundant entries that could cause problems.
If you have problems uninstalling/reinstalling, troubleshoot with the suggestions in this post.
Check that your computer isn't overheating, especially if your problems occur during rendering. Clean out the vents. Consider opening it up to gently clean dust from the inside. Use laptops on a hard surface that keeps the vents unobsructed (e.g. not a bed, carpet or your knee). There are many PC temperature monitors available. I always have Core Temp running minimised in my task bar. An acceptable CPU temperature depends on the individual system. Mine (see ) cruises at about 50°C and goes up to about 80°C during a tough render.
21. HARDWARE ISSUES
Your stability issues may be caused by failing hardware, in particular memory and storage. Test your computer's RAM for problems and replace any faulty sticks. Test your hard drive for faults. Backup/replace hard drives at the first sign of trouble. If you CPU, GPU or memory are overclocked, try setting them back to the standard speed.
22. SCAN FOR CORRUPT WINDOWS SYSTEM FILES
23. REGISTRY CLEANING
If you have tried all the above steps, you could try cleaning your Windows registry. For this purpose I regularly use Ccleaner free version. Cleaning your registry carries significant risk. It is recommended to take an image-based backup of your system drive first, for example using AOMEI Backupper or Macrium Reflect Free or Acronis True Image. You can also make an image or create a system restore point in Windows. When Ccleaner asks if you want to backup your registry before cleaning, you should! I usually fix all detected issues and then scan for issues again. Further issues are often found the 2nd time. Reboot afterwards.
24. IF YOU STILL NEED HELP
If the above steps do not help you solve the problem, make a forum post and/or support request, including the following information:
- Your system specifications (with reference to step #2, above)
- Exactly which version and build number you are using
- The exact procedure that causes the crash, or the exact symptoms of the problem, and the exact contents of any error messages
- The type of media you are using, if this is relevant. MediaInfo and VEGAS Pro File Properties reports are useful.
- Description of any plugins you are using
- If VEGAS crashes and displays a Problem Reporting Service (PRS) window, send the error report to the support team by this method.
