Vegas Pro 21 has been pretty stable since I purchased it about two months ago. Recently it started to freeze more often during the last project. Since I had around 50 to 60 video parts in 4K in there, I thought that the program's capacity was exhausted, although with 32 gigabytes of RAM I still had a lot of room for improvement - over 10 GB - in the project and no more programs at the same time.
Since yesterday the problem has gotten significantly worse. I'm starting to get pretty disappointed now. I started a new project in just 1080p. Vegas 21 now starts to freeze constantly (see screenshot) after I added the first 30, all quite small videos of 5 - 12 MB in size. This now happens every time I add a new video, I've tried several, it's the same for all of them. The videos are not particularly large, only 10 to about 32 MB, but they are all in 2160p! Apparently Vegas can't handle the added video being 2160P!?. However, it initially ran perfectly with around 3 previously added videos in 2160p! Now the screen remains frozen as the screenshot shows. Sometimes the Windows message appears that Vegas is no longer responding, usually I have to close the program using the task manager. What you notice here is that “Microsoft WebView” is always called up under Vegas Pro in the task manager. Maybe this doesn't work well with Vegas Pro 21? Why is this used by Vegas Pro?
My computer requirements are way far above what is necessary for Vegaspro. With previous projects in 4K, working with Vegas has not been a problem, apart from the problem mentioned above.
I find it very disappointing that previous program versions which were also previously saved even don´t work anymore! When I tried to reload Vegas Pro, regardless of whether the computer had been restarted or not, it immediately froze, even though it had worked up to that point and was saved before - I had saved a new version then the problem arose! In the previous project there were already one or two 2160p videos, but they didn't cause a problem at first. I also completely reinstalled Vegas with all additional plugins, which unfortunately doesn't make any difference. I have had all Windows updates checked, which are all up to date.
I'm now very frustrated with this poor performance. Today I spent over 5 hours uninstalling, reinstalling, deleting parts of the program, going back to previous versions of the program and trying to add the videos again, without success. Has anyone here experienced that or an idea what´s going on?
