When I add a lumetri effect and make any adjustment my playback turns to white. It's happened before and this specific time it went to white when I tried to add some vignette to my image. Didn't change any other attributes inside Lumetri.
Seems like it's an error with Lumetri? Rather an inconvenient error because I can't make any changes without the image turning to complete white.
Tried nesting to get around it but didn't have any luck.
what are your source properties and your sequence settings? Any chance any of your sources are from a smartphone or a screen recording? If so, the problem may be sources with variable frame rate. Here's how to diagnose and resolve the issue.
