Clip underneath "Essential Graphic" is frozen

[Dan McKinney]

I do real estate video and I open each house tour with a graphic from the "Essential Graphics" panel over a drone video. Always works, except in this ONE video I'm working with.

If I overlay the graphic on the drone video, the video clip renders as frozen, just a single frame. All the other clips in the video, shot with my Lumix GH4, work as expected under the same graphic. Only the clips from my Mavic 2 freeze under the graphic! I don't get it.

I ended up using VLC to convert the Mavic video clips in question - although the conversion simply consisted of saving them to new file names, still H.265 videos, same frame rate, same size. Looks to be identical settings, unless I'm missing something.

What would have caused this kind of beahvior?

Try deleting your cache files... be sure to drop a clip onto the timeline before you drop the graphic...

• Start PP from it's normal desktop icon (IE: don't open from a project file link).
• Close the Open/Home screen (and you will be in PP without a project open).
• Go into Edit/Preferences/Media Cache (Mac users adjust menu name)
• Then Press: Remove Media Cache Files: and Delete...
• Select: Delete all media cache files from the system and OK
• Close PP - It will create any needed cache files on the fly as you edit.

That did it, and it makes sense to me, too. Somehow. I had a feeling it had to do with caches, but didn't quite know how to approach it. With the old cache gone, now the original Mavic clip renders /  previews just fine.

Thanks - such a simply fix!
