from another forum. In the future…..
In the bin with the stills, display them in script view.
Select all of the stills.
Press the “Go 10 Frames Forward” key however many times you need to get the amount of handle you want. For example, if you want 1 second of handle, press the key 3 times.
Mark in.
Press the “Go 10 Frames Forward” key however may times are required for the duration of each still. For example, if you want each still to be one second long, press the key 3 times.
Mark out.
Your stills have in and out marks leaving handles. If you want individual lengths of time for each still, then this won’t help you at all, and you’ll have to do each one individually.
