I’ve been inserting motion graphics using mocha Pro 2019.5, into to clips that had up to 13 monitors. My system was to take the BG plate, apply mocha Pro, track the shot and then insert a motion graphic file into one monitor. To save tracks, I found that I could import the original file rather than have the insert on the layer below.
When I updated to 2020 that system broke. The inserted screens were black. When I opened up the effect editor / mocha interface and pointed the Insert Clip back to the .mov file, I got an error that that file type was not supported. I tried to import that file again and all the .mov files were greyed out and not selectable. I removed the file filter from the selection window (to accept all file types), and got the same error when selecting the .mov file.
Is this a bug or a change in the program?
When I went back to 2019.5 my imported files showed up.
