Two problems I am having:
1. When I add time warp to my clip or nested sequence, the preview clip suddenly appears to be scaled larger if the clip is sitting within a higher resolution sequence. The transformation is not dissimilar to having the "scale to frame size" option checked. The actual speed based time warp effect appears to work fine, so I can workaround this by simply applying this to the clip within a sequence that matches its resolution
2. Motion blur is not working at all...the default settings manual shutter control (shutter angle: 180, samples 5, pixel motion enabled) produces no blurring. I have processed this same file in After Effects CS4 and it works beautifully, but I wanted to try applying the effect directly to edited clips so that the blur effect does not span cuts as it does when I apply it to the entire file
Purely a gues here, but 1 may be working as designed.
I have not used the Motion Blur effect yet.
