  • using Time Remap with an animation – problems

    Posted by Brian Tetamore on September 6, 2006 at 4:40 pm

    Okay, I’m stuck. I am taking an Animation, 720 x 480, Millions, FPS 29.97 and using Time Remap in AE 6.5 to reverse it at the end to go back to the beginning. It’s a building fly through and we want to go in and them come back out. The AE 6.5 comp settings are 720×480, DV/D1 NTSC 29.97 fps.

    I’m making a movie using, Best/Full/low fields and the 8Bit Uncompressed codec.

    When you view the resulting QT movie every third set of three frames the interlacing gets messed up. It’s as if the upper field is many pixels shifted to the left horizontally from the lower fields. Then next few frames are fine, and then the problem appears again. Of course, when viewed in FCP and finally on DVD it looks like stuttering movements.

    On a second test, I used the same comp with the Time Remap only selected NO FIELDS. The resulting QT movie looks fine until you reach every 5/6th frame. It’s as if it copies the previous frame and there in no (camera) movement. The original animation starts at one location and constantly moves through the building and then comes to a stop in the new room. There are no oddities in the original animation.

    In the past, all I could do was just “time reverse” the layer and butt it up against the normal layer. I could not use Time Remap to adjust and soften the speed.

    Any thoughts? Am I missing something?

    I stepped through the original AE comp where the animation layer with Time Remap is applied. Every 6th frame is like a hold frame or a copy of the previous frame. It’s plays like the camera stops, and then starts moving again for the next five frames.

    Trying to nail this down.

    Any takers?
