Help with Fusion Blue rectangle effect after merge!
Hello! new here posting, but I've been lurking and researching some. I've come across this pesky problem with the fusion section after trying to merge two distinct video files. I select both videos in the Edit section -with their corresponding audio, I then right click and choose 'New Fusion Clip...'. Then in the Fusion section, I get this ambulating blue rectangle. only one of the video files shows but not the background one. That's the one that has been turned into the blue rectangle.
One is .mov and the other .mp4; I know that resolve can co-mingle these two file types, so I don't believe it to be the problem.
Any insight as to what I may be doing wrong? or a setting I need to toggle/adjust maybe?
I should note that the video clips are different lengths.
Thank y'all!! I have provided screencaps to better show my dilemma.
