Hello,
I am using vMix version 28.0.0.42 on Windows. I have several different vMix projects saved.
Here is my workflow:

I open Project 1 and record a session.
I close Project 1 and open Project 2.
I start a new recording in Project 2.
The problem is that, at the beginning of the recording in Project 2, a few frames from the end of the recording in Project 1 appear. It seems like vMix is retaining some video frames or caching content from the previous project, and this is carried over to the next project, even though I have opened a different vMix project file.

Is there a way to fully clear or flush the video buffer/cache when switching between projects, so that no frames from the previous project are present in the new recording?
Are there any settings or best practices to avoid this kind of “frame overlap” between project recordings?
Any advice would be greatly appreciated!

Thank you.

As Tom said -> vMix support.
Have you tried a relaunch of vMix instead of "just" opening the other project.

I have back-to-back live shows, so I can't do what you're suggesting. The issue needs to be resolved.

I agree that this needs to be resolved.
But personal experience. Because we have to deal with Windows program sometimes close and open it again can save the day. I learned it the hard way..

Sure, but if you have to switch from one live broadcast to another and you only have 30 seconds, it becomes problematic.

Blimey, I wouldn't want to be using a different project even if there was a 15 MINUTE gap between broadcasts!

Is there no way you can merge the two projects together?

Unfortunately, the projects are different from one another, and I usually do 10 live broadcasts in a row. Every 30 minutes, I have to switch projects. I tried using a single project, but it becomes very heavy and complex to manage the shortcuts.
