I am completely new to After Effects and have just completed my first 15 minute movie in Premier Pro (CS5). This movie is very important to me and encroaching a deadline. I wouldn't reach out with such a beginner question otherwise, so any assistance would be greatly appreciated.
Have Tried -
Please let me know (from the very basic starting point) how you would do this? Is there any way to stop and start the motion track linearly along the timeline in different positions, and apply different effects?
Thank you in advance.
Todd's right; without a basic understanding, it's going to be hard to help you.
However, I can try.
Instead of bringing your whole video into AE. Just copy the clip in Premiere that needs the effect and paste it into a composition in AE. Trim your composition so it's just that clip. Follow whatever tutorial you followed to get your effect done (I'm assuming the Demon Face Warp from VCP) and render your video out of AE. Then simply plop that clip over the original clip in your Premiere timeline.
But seriously, you will save yourself much hassle if you go through all the resources Todd linked to. AE is a pretty powerful and complicated program. It's not something you can learn in a day, so charging forward into it will only cause frustration.
