I'm having some issues with the bad tv effect in final cut x ver. 10.2.1.
I've set out three keyframes on the timeline to make it go from 0% to 100% back to 0% within about 5 frames. The thing is that nothing happens, the effect doesn't appear. It just kind of shakes a little. What am i doing wrong?
I believe the behavior that you are seeing is that it doesn't stay at 100% long enough to really show you the effect. Try using 4 keyframes. 0 to 100, then 100 for 5 seconds, then 100 to 0 (so 0, 100, 100, 0). Set the distance between the two 100% keyframes for as long as you want the maximum effect to happen.
