Freshly installed 2020 version, and the moment a .mov is inserted to the timeline the program freezes. Works with all other formats, and the .mov plays otherwise in any media player installed. Cannot find a path so far to stop the freeze.
It is a Windows computer. In all prior versions I have had no issue with the .mov format. The files play fine in all players installed. And they will load to the timeline, then promptly freeze the program. Not a hard lock, just frozen. The error is shown as "Low level exception mpeg importer". I`d love to use the newer program for it`s improved features, but without a solution/update I may have to toss it into the ocean.
I'm having a similar issue. Imported HEVC video loads, but preview screen goes black with any attempt to scroll through or play the video. When the preview locks up the entire program becomes sluggish and remains so until manually shutting down the background process in task manager (otherwise background process keeps running even when the window is no longer visible). Do you have MediaInfo? You can use that to at least see the codec embedded within the .mov. It's usually the video stream codec itself rather than the file container that causes problems.
