Tween 2 Keys

Tween 2 Keys is an Adobe Flash plugin that will help you convert the selected tween to keyframes on two's. This is useful when you're animating on two's and you want to use tweens.

Tweens are always on one's, and it looks odd to have an animation go back and forth between one's and two's, but converting a tween to two's manually is very tedious and prone to error.

To use this command, select the starting and ending keyframe of the tween and run the command. It converts the selected frames to keyframes, then clears every other keyframe.

Because it is clearing keyframes there is the potential to accidentally clear a keyframe you wanted to keep, so use with caution and don't forget to save! It will not clear the last keyframe in the selection, even if it is on one's.

This command can take a while to do its job if you a lot of frames and/or layers selected. It was intended for short segments of character animation, but if you have some long tweens (like camera moves or panning BG's) then it's probably best to do one layer at a time to prevent Flash from running out of memory.
