After the last two posts (found here<\/a> and here<\/a>), I was able to quickly create a script that would scale all selected takes within a scene to a specific frame length.<\/p>\n

This could be handy if data needed to blend or needed to conform to a specific length for game play.<\/p>\n

The script is easy enough to use, just execute it within your scene then select the takes you wish it to be applied on and type within the python console\u00a0 ScaleTakes(length).<\/p>\n

ie:\u00a0ScaleTakes(15) will scale all selected takes to 15 frames.<\/p>\n

As a bonus all layers on the take will be merged together, the clip will be moved to start on frame zero (if it did not already) and your time line length will be adjusted to fit the new length.<\/p>\n

I hope this post does two things;
\n1. Shows how having a library of functions at your disposal can speed up your scripting
\n2. Gives you a new toy\/tool to play with.<\/p>\n
As always, I hope this helps.<\/p>\n
