Hi to all having the black clip syndrome.. I found something that may work for you. If at all, you have any special characters in either the folder names or the file names of your video clips, you will have the black clip issue.
The guy who handed off the videos for me to grade had a folder name with an * and an è. I changed those out. I then proceeded:
Go to my media pool under the media section in Resolve.
Test right+click and changing the parent directory. Update the name of the folder changed and voila!
The clip is updated.
I selected all the remaining clips and did the same.
It then didn’t work for two additional clips, but can you guess why? One of those clips had a “é” in the name and the other had another “é” and “&” symbol. It likes to replace the “é” with a question mark in resolve — a little clue maybe?
The folder name change is updated by “Change the parent diretory”.
The file name change is updated by adding those clips back in to the media pool and then adding the clip back in the timeline. The two I had problems with automatically received their correct grading magically.
Hope this “resolves” pun intended, your issues with the black clips!
