I've never experienced this before, but after applying Time Warp to a layer of footage ("Sequence-A" let's call it), and then removing that footage sequence from my timeline, a static image from Sequence-A remains when the preview playhead reaches another layer of footage in the timeline ("Sequence-B"). Sequence-A and Sequence-B share no files.
Even after deleting Sequence-A from my project item list altogether, the static image that derived from it remains, again, only on Sequence-B which has a Time Warp effect on it as well. I tried removing Sequence-B's Time Warp, but nope, the static image remains. When exporting, the static image does not show up however; thankfully.
Does anyone know what might be going on? Is this a bug, or some bizarre setting that I accidentally toggled? I've used Time Warp quite a bit and have never encountered this issue. Thanks!
EDIT: Here's where things get really weird -- attempting to flee this ghost image, I thought I'd re-composite the whole scene in a fresh file -- I create a new blank AE project file, create a new comp and there it is again! There are no files in this new project and the image remains. What is going on?! Ugh.
Cleaned my cache and that solved it. Mystery crisis averted.
thanks for sharing. the forum is a good place to help yourself.
