speed change in timeline?

[Thaxter Clavemarlton]

You need to adjust the speed of your clips BEFORE they are edited to the timeline.
But you can solve this problem afterwards by adjusting the matching “original” clip(s), then editing these newly adjusted clips to replace the one(s) on your timeline.

On the timeline: Put the cursor on the FIRST FRAME of the clip you want to Slo-Mo or Fast-Mo.
But do NOT double-click IT into the viewer, but hit CMD-OPT-F (Match Frame to Source File) … this loads a ‘temporary’ copy of the real “original” so a “match-frame” appears in the Viewer.

Then, adjust the speed of the clip in the Viewer (Cmd-J) to any percent you want.

Next, on the timeline, use REPLACE to change-out the regular-speed clip with the newly speed-adjusted version.

Your other clips will all stay in place.

Thanks, that cmd-opt-F will be handy…

That’s a great tip. Thanks.

Also if you have your ‘slomo’ clip in a track of it’s own on the TL, and lock all the others.

Another thing you can do that won’t move anything else in your timeline is to use the “Fit To Fill” function. For example, let’s say you have 3 seconds of footage that you want to fill a gap in your timeline that is 7 seconds long. You want it slowed down but you also want all of those 3 seconds in there and figuring out the math is a pain in the butt. Here’s what you do:

At the beginning of your 7 second gap in the timeline, place the 3 second clip. At the first frame of the 7 second gap, set an in point. Go to the end of the 7 second gap and set an out point. In the timeline, double click on your 3 second clip so it appears in the Viewer. Then, drag it from the Viewer window to the Canvas window and into the Fit To Fill box. Viola! The clip is slowed so the 3 seconds of footage fit perfectly into the 7 second gap and nothing else in the timeline moves.
