Hello, can someone tell me what these lines mean and how to remove them?
It could be an unserialized plugin/effect/etc or a Grid Effect. You should be able to tell by looking at the Timeline to see if any effect(s) is applied. Then toggling off/on the effect(s) to see if it removes the grid.
Thanks for your help. I have found the effect that has caused this, it is the flicker free effect. I still need the effect but withought the grid lines. do you have any tip?
You'll have to head over to the developer's Website to see how you can have the grid removed since this looks like a licensing issue.
Great, thanks again for your help!
