I added a Mask: From File filter to a clip, then selected “custom file” for the file and pointed it at a png of a gradient. I then keyframed the threshold of the mask in order to create a drop-down effect.
However, after I saved and then reopened the project, the mask filter doesn’t seem to be doing anything.
Despite the fact that the filter still claims to be pointing to the file.
If I then go File → Custom and reselect the file, it works as expected again. (at least until I reopen the project.)
Here is the example project in question
