And there is an easier way if you are still on 6:
1) Match Frame your in point
2) apply speed change to master clip in viewer
3) Replace edit
4) Change speed back to 100% in Viewer for later use of Master Clip at normal speed
voilà , no ripple in version 6
and if you do a source match frame (cmd – opt – F) instead of a match frame, you don’t have to change the speed back as your master clip is unaffected.
Hope this helps
