so you turn on the volocity envelope, but then how do you make it freeze...I'll play around with it, but let me know if you can be more specific on how to do this.
At the point where you want it to freeze, add two points. Leave the first one at 100% and make the second one 0% (right click and choose Set To... and type in 0)
Another way is to take a snapshot of the frame and add it to the timeline at the end of the clip for as long as you want it to pause. That way you can add FX if you want (pan/crop, etc.). To get the snapshot, just put the cursor on the frame you want (shows up in preview window) and hit the little save icon above the preview window. Then select the format and location to save it to. Then load it into the media bin and move it to the timeline. Hope this helps.
