Whenever I first run Sony Vegas and load into a project, I am able to use the pan/crop tool and any sort of effect I want very smoothly and the program runs just fine. However, after running Sony Vegas for about 5-10 minutes, it starts to slow down significantly, especially when I'm saving my work. The pan/crop tool will start to run at 10 fps and doing any sort of key-frame work becomes extremely tedious because of how slow everything is running. I did some troubleshooting and found that saving my work multiple times is what is causing the majority of the lag. I've gotten into the habit of saving so often because of how often Sony Vegas crashes. I'm using Sony Vegas Pro 15.0. Some other things to note:
- It doesn't matter how big the project is for the lag to happen. I tested saving multiple times on a project with a 7 second video clip and it was just as bad as the test with a 3 minute project with multiple effects and layers.
- Once this happens on one project, the lag carries over onto other projects if I don't restart Vegas.
- Vegas runs perfectly fine once I restart it.
- My GPU and CPU temperatures are fine while it's happening.
I have tried to solve it by doing the following:
- Disabling so4 compound reader
- Enabling Multi Stream Render
- Disabling GPU acceleration
- Setting CPU priority to high in task manager
- Turning off thumbnails
- Reducing preview quality
Some PC specs:
- gtx 1080 GPU
- AMD Ryzen 7 1700 8-Core 3.0GHz
- 16 GB of RAM
- Windows 10 version 1803
Just to be clear again, I'm not talking about the preview window lagging. I'm talking about using any sort of editing tool, such as pan/crop, key-framing brightness, etc.
