I stumbled upon a great AE expression that couldn’t have come at a better time. Originally from MaxX at Motion-Graphics-Exchange, this little sucker can take out any pesky double frames in your footage. Just add this expression to a time remapping and voila!

f= timeToFrames();
p = Math.floor(f/1);
framesToTime(p*1.25)

This one is set to take out every 5th frame, if you want to change which frame to take out, just mess around with the multiplier in the last line. Works like magic, and just made my life oh so much easier. Thanks MaxX!
