What clearing cache does in Vegas Pro 22
Vegas Pro 22 stores temporary files — preview images, rendered clips, and project data — in a cache folder to speed up playback and editing. Over time this folder grows large and can slow down your system or cause the program to behave unpredictably. Clearing the cache removes these temporary files without affecting your actual project files or settings.
You should clear cache when Vegas Pro 22 runs slowly, when playback stutters, when effects previews take too long to load, or when you notice the program using unusual amounts of disk space. A full cache can also cause crashes when you open older projects or switch between different video formats.
Key Takeaways
- Vegas Pro 22 stores temporary preview and rendering files in a cache folder that grows over time and can slow the program down.
- You clear cache through the Edit menu under Preferences, then Disk Cache, without needing to restart the program.
- Clearing cache removes only temporary files — your projects, media, and settings remain untouched.
- The cache folder rebuilds automatically the next time you open a project, so clearing it regularly is safe and has no lasting side effects.
How to access the cache settings in Vegas Pro 22
Open Vegas Pro 22 and go to the Edit menu at the top of the window. Click Preferences near the bottom of the menu. A new window will open with a list of categories on the left side.
Look for Disk Cache in that list and click it. You will see options for cache location and size. This is where you can clear the cache or change where Vegas Pro 22 stores temporary files.
Clearing the cache with one click
In the Disk Cache window, you will see a button labeled Clear Cache or Empty Cache depending on your exact version. Click this button. Vegas Pro 22 will delete all temporary files in the cache folder when ready.
The program does not need to restart. You can keep working on your project right away. The cache folder will start rebuilding the next time you play back video or explore effects, so you may notice a brief pause the first time you preview something after clearing.
Where Vegas Pro 22 stores cache files on your computer
By default, Vegas Pro 22 stores cache files in a folder buried inside your user account. On Windows, this is usually C:\Users\[Your Username]\AppData\Local\MAGIX\Vegas Pro 22.0\cache. You do not need to navigate there manually — the Preferences window handles it for you.
If you want to move the cache to a different drive (for example, to a faster SSD or an external drive with more space), you can change the cache location in the same Disk Cache window. Click the folder icon next to the cache path and choose a new location. This is useful if your main drive is running out of space.
How much disk space cache typically uses
Cache size depends on how long your projects are and how many effects you preview. A typical project might use 500 MB to 2 GB of cache. Very long projects with heavy effects can use 5 GB or more. Vegas Pro 22 lets you set a maximum cache size in the Preferences window — once it hits that limit, the program deletes the oldest temporary files to make room for new ones.
If you are working with 4K video or complex effects, you may want to increase the maximum cache size so Vegas Pro 22 does not delete previews you still need. If disk space is tight, you can lower the limit and clear cache more often.
When to clear cache versus when to leave it alone
Clear cache when the program feels sluggish, when you finish a large project and want to free up disk space, or when you are switching between very different types of projects (like moving from 1080p to 4K). You can also clear cache monthly as routine maintenance.
You do not need to clear cache before closing Vegas Pro 22 for the day — the program manages it automatically. Do not clear cache in the middle of working on a project if you are actively previewing effects, because you will lose those previews and have to render them again.
Troubleshooting cache problems
If clearing cache does not fix slowness or crashes, the problem may be elsewhere. Check that your hard drive has at least 10 to 20 percent free space — Vegas Pro 22 needs room to write new cache files. If your drive is nearly full, move media files or projects to an external drive or delete files you no longer need.
If crashes continue after clearing cache, try moving the cache folder to a different drive. Right-click the cache folder in File Explorer, select Properties, and check how many files are in it — if there are thousands of corrupted files, moving the cache location can sometimes fix the problem. You can also reinstall Vegas Pro 22 if cache corruption persists, though this is rarely necessary.
Frequently Asked Questions
Will clearing cache delete my projects or media files?
No. Cache contains only temporary preview and rendering files. Your actual project files (.veg files), media files (video, audio, images), and all your settings remain untouched. Clearing cache is completely safe.
How often should I clear cache?
Once a month during normal use is reasonable. If you work on very long projects or use heavy effects, clear cache every two weeks. If disk space is tight, clear it weekly. There is no downside to clearing cache frequently.
Why is my cache folder so large?
Long projects with many effects previews generate large cache files. 4K video also creates bigger previews than 1080p. If cache grows beyond what you set as the maximum size, Vegas Pro 22 automatically deletes old files, so it should not grow indefinitely unless the maximum is set very high.
Can I delete the cache folder manually from File Explorer?
Yes, but using the Preferences window is safer because it closes any files Vegas Pro 22 is using. If you delete the folder manually while the program is open, you may cause crashes. Always clear cache through Edit > Preferences > Disk Cache instead.
What if I do not see a Clear Cache button?
Older versions of Vegas Pro 22 may label it differently or place it in a slightly different menu location. Check under Edit > Preferences > Video, or look for any option mentioning "temporary files" or "disk space". If you cannot find it, restarting Vegas Pro 22 and trying again usually works.
