Following the short tutorial here to make a loop in After Effects using time remapping and the loopOut() expression I encountered some odd behaviour. In the tutorial it is mentioned that when this method is used a black frame appears between the loops. To remedy this problem one needs to create a new time remapping keyframe the frame before the last one and then delete the last one. This should give a smooth loop. However, instead of the black frame my frame gets "sheared" as shown below:

Normal frame: enter image description here Sheared frame: enter image description here How can I get a loop using (preferably using loopOut) and not get a sheared frame in the loop? I'm using After Effects CS5.5 on Mountain Lion 10.8.3.

This seems very odd. Are you sure this isn't a problem with the source file? How was the source originally developed? –  AJ Henderson May 31 '13 at 13:36
    
I am applying the time remapping to a pre-comp containing three layers with identical content. The content is a jpeg sequence of 5 frames, looped 10 times (through interpret -> loop). I have three layers, one of them is the main image, the other two are masking the sides of the image with the same content. Playing the pre-comp without time remapping works fine. –  Bart Arondson May 31 '13 at 19:22
    
Any chance you could post the project files somewhere that we could take a look at them. The behavior seems very odd. –  AJ Henderson May 31 '13 at 19:23
    
I've uploaded it here: mediafire.com/?837pzj72hpd5z9r The behaviour seems to revert to a black frame instead of a sheared frame after a restart of AE. However, if I replace the last keyframe in the new session, the sheared frame is present again. –  Bart Arondson May 31 '13 at 20:15
    
Yeah, the black frame is more what I would expect. The shearing is very odd behavior. –  AJ Henderson May 31 '13 at 20:44
