UPDATED: A quick update that will now allow the script to maintain all of the original tracks within the story. The story will look exactly as it was pre-processing. Thanks Simon Kay<\/a><\/p>\n\n\n\n

Below is a script that I wrote, It goes through all you Story tracks and clips and then processes them into new Scene Takes. Each clip will reside on its own take and it will be shift along the time line to start at frame zero.<\/p>\n\n\n\n

I would use this tool for any long mocap shots that needed to be cut up into a number of smaller moves.<\/p>\n\n\n\n

The Script was a very quick development on my part and will only be effective for Character Tracks. It is not going to provide you with any proper processing for clips that are blending into one and other. The number of clips you have sliced up within your Character Tracks will equal the number of new takes the script will create.<\/p>\n\n\n

This was a very quick test that I did over a lunch one day, there are a number of features that I would like to someday implement as well as making the script none destructive to takes\/clips. I hope this helps speed up your work flow.<\/p>\n\n\n\n
I hope this helps.<\/p>\n
