In another discussion of Auto ripple issues, I came across this thing by testing VP8/10/11/12
Use File / Open to open a folder, and select a folder with many video files. For example, 50 or more. Use CTRL + A to select all and wait for them to be selected.
In the old versions, it's perfect. Instantly and without Vegas freeze.
In versions 17/18 long with occasional freezing.
Here are the examples.
The comparison shows that in VP12 the delays start to be longer.
Can you confirm this behavior?
