I’m adding a 3-Way CC to clips in FCP and rendering them out. When done for the night I shut done computer and then open the next day only to find the 3-Way filter no longer attached to clips. 99% sure I save project before shutting down at night. Where could the problem be?
Check your autosave vault and see if the latest project has the filter(s) applied. If not, your probably did something wrong. Although, it’s kind of hard to mess up applying a filter to a clip.
