Hello!

Recently switched from Mp4 to HEVC. This dramatically reduced CPU and GPU overhead, and the files are smaller which is nice. Render times dropped by about 25% which has been a HUGE help.

However some of the files (especially in lists) are behaving strangely.

If I have a list of HEVC video files and I change from one to another on the list (by hand, script, or auto play next) the video will not display. The sound is fine, but the video is black.

If I simply click manually on the file, it will suddenly appear and function normally (about 95% of the time). Just needs a single click AFTER it's already selected.

I have about 8 lists, and this bug affects all of them, so I need to manually re click and changed video files.

If I change video files on a list (without the second click), save vmix, close and restart it, all of the files Display correctly (till I change them again).

On rare occasion re-clicking the file does not work. In those instances saving and restarting usually does.

Not sure what causes it, but it's added a significant layer of complexity to production. I have to cherk every video in a list, and click it if it's blank. If I'm changing videos by script, I need to re-click them by hand as well.

Anyone have any thoughts?

Nick
