When i add rolling titles above a clip with slow motion (the clip under) the video under starts to jiggle, its not smooth. what can this be from. thank you.
- Select the timeline and right click
- Select "Field Options"
- Within "Field Options" you have a choice of None, Interlace Consecutive Frames, Always Deinterlace, Flicker Removal.
Typically you use the last two (Always Deinterlace, Flicker Removal) more than the others.
Try different variations of these options and see if you can't get the flicker to go away-- be sure to render after applying.
