    Speeding up clip on timeline introduces more footage...

    Hi everyone, I have a small issue here. I am trying to speed up a 15 minute clip on the timeline. The problem I am having is when I speed it up, say to like 500%, it introduces parts of the clip that I originally cut out.. I have to go through and re edit the sequence/end of the clip that is sped up to remove what I do not want. How can I anchor the beginning and end of the clip and speed up only the cut footage that is already there? Thank you!

    You'll have to shorten the shot.

    If you think carefully about it, you can't simply 'anchor the beginning and end of the clip and speed up only the cut footage that is already there' Imagine your clip is like a length of elastic - shorten it (as the other reply suggests) and it'll run faster. Lengthen it and it'll run more slowly and you'll lose some frames unless you trim it out and lengthen it.

    It sounds like you want to use the selection in the timeline to create a shorter clip that runs at 5 times normal speed, and will therefore be 20% of the duration?

    So either use a timewarp:trim to fill effect and trim the clip to 20% of it's length.

    OR alt+match frame the timeline clip to load it into the source window with your mark in and out intact. Then use the source motion effect editor to create a new clip at 500% speed, remove the old clip and cut the motion effect one into your timeline.
