Cant figure this one out. Images attached Can't Post
When I place a speed change to 50% on the last clip on V2 it expands the clip (as it should) but the 2nd Color clip on V1 along with all the other clips after the 2nd clip push over to the right the same amount as the clip on v2 is expanded.

I have to lock track V1 to prevent that whole track from shifting to the right. I can't understand this to save my life!

Welcome to the vagaries of slow motion in Final Cut Pro. Locking down the track is one way to do it, but you have to be careful because your audio can go out of sync. Fit-To-Fill is one way to get around this, but you can't predict what the percentage will be. My kludgy way of doing it is to have a very small sequence that is positioned so I can drag clips to it for quick speed changes and then drag it back again:

http://tinyurl.com/298hnx

The following is one technique that seems to be more work than its worth. Its from Andrew Balis' article about mastering match-frame editing on KenStone.net:

http://www.kenstone.net/fcp_homepage/matchframe_balis.html

Using Match Frame to do Slow or Fast Motion Without Rippling the Timeline:

Let's say you need to speed up or slow down a clip, but you want more control than doing it in the timeline. When constant speed effects are done in the Timeline, the duration of the clip changes, and the Timeline clips to the right of the affected clip will shift left or right depending on whether slowing down or speeding up. Sometimes this is what you want, other times it isn't. Here's another way to do it using Match Frame.

1. Locate the clip in the Timeline to do a speed change, and move the playhead anywhere over this clip.

2. Press F to open the Browser original into the Viewer.

3. Go to Modify > Speed (Command/J).

4. Modify speed as desired. So far, this is not affecting the clip in the Timeline as that will happen in the next steps.

5. To keep the Timeline clip at the same duration with the new speed change, start out by making the Timeline window active and press X to mark the clip.

6. Set a new in or out point in the Viewer as desired.

7. Drag this clip from the Viewer to the Canvas and drop on Overwrite. This adds the speed change to the Timeline.

8. One last step to take, correct the Browser clip back to normal speed. Although the correct clip is in the Timeline, we've altered the Browser clip so that each time its called up, its speed will have already been affected. To change the Browser clip to normal speed, click in the Viewer window to make it active, go to Modify > Speed and change it back to 100%.

I can't figure it out, either. Pain in the ass...can't find any explanation in manual, so I just put the clip I want to modify on my top video track (which I keep clear of anything else just for this purpose), lock all the other video and audio tracks, make the modification, and then unlock everything and move the clip to my desired position on a lower track.

The one thing I picked up from the manual that might avoid this is to open the clip in the viewer and set in and out points. On the timeline, set in and out points for the space you want the clip to occupy. Then drag the clip from the viewer to the canvas window and drop on fit to fill.

Well it just doesn't make any sense. Why should changing the speed of one clip on a different track push unrelated clips on other tracks over?

Thanks for the response Joel, I'm still trying to figure out what it is your saying.

By changing the speed the clip either gets shorter or longer. Slow it down and the in and out points of the clip don't change, the clip gets longer. Anything that is downstream gets pushed toward the end. Make the clip faster and it becomes shorter, moving everything after it closer to the start.

Thanks Joel, I understand all of that. And that's how it should work for anything on that same track. However, my question is: Why should a speed change to a clip affect other unrelated clips on other tracks? I could see it having an effect if other clips on other tracks were linked to the clip that has the speed change. but that's not the case in my example. Changing the speed of that one clip on the top video track shouldn't affect the entire sequence, iMHO.

I guess there are some things that Premiere Pro did get right, and this was one of them.

Actually, Ron, it does make sense in some cases in that, when you have clips layered on tracks (such as superimposed text or graphics), you don't want just one track to shift. Then your text/graphics will end up in the wrong place.

Still, it would be nice if there was some toggle that lets you choose between slipping all tracks or just the one track that your clip is on...without having to lock all of the other tracks.

Okay, I can accept that, I'm sure the programers probably know more about it then me, and maybe that is what Joel was trying to tell me. Sometimes.... well once or twice in my lifetime I've been peg-headed and think I "know it all" but most of the time.... I do know it all!! Wink

No, the programmers are idiots for not making the slo mo more like premiere or vegas...This has been an issue forever and they still haven't addressed it... They suck.

And as for variable speed clips - don't get me started...
