FCPX keyframe help

[diamond3]

I am at the very end of my project and I noticed my clip goes way outside my viewer window in one segment of the video.

I checked the keyframes and there are two of them set at the same location, distortion and scale about 10 minutes apart without any keyframes in between them Somehow my clip is tracking some 12000px outside my viewer/canvas so I can't see the end of it.

Any ideas for a fix? It would take hours if I have to delete every keyframe after it and start over.

If you don't know of a fix, is there a way to move the canvas located in the viewer window so it's not centered? The way it is now, even at 15% zoom, I can't see the end of my tracking where it starts to returns to the second keyframe at the same location as the first.

I'm not sure, but I've had some trouble with weird interpolation between keyframes. Meaning that if you set one keyframe just a few frames after another with some major changes, and then the next one is further down the timeline, the interpolation between those two will be unpredictably strange.

I had set all keyframes to linear interpolation (which is also the default), but this didn't seem to work. What worked for me was setting and unsetting a keyframe a couple of times just next to the one I don't like the interpolation at. I found this workaround on the internet until they fix it.

In your case, this would mean:
- if keyframe 20 is at 04:00:03 and keyframe 21 is at 14:00:03
- create a position keyframe at 04:00:04
- delete said keyframe again and create it again
- repeat a few times (5-10)
- create a position keyframe at 14:00:02
- do the delete and create procedure again.

You can actually see the footage move around even though you are not changing parameters, but merely adding keyframes and deleting them.

Good luck, maybe that actually is the problem.

Is it a linear keyframe or ? But that seems excessive.

I tried creating another keyframe a frame later, midway between the two and nothing changes. The keyframes are several minutes apart, long enough I guess to go clear out of the picture. It's great fun. As I went back to it this morning, I noticed it went 100,000 px out in the x-axis and 40,000+ in the y-axis.

Since that didn't do anything, I went through and deleted all of the distortion key frames and from what I recall, that fixed it. So as I went through applying the adjustments back one buy one, I thought I was clear. That is until I went back and played the first part again and it reset and gave me the same problem.

So, I gave up, turned off all motion and exported the clip. Downloaded a trial of Premiere Pro and completed the project in no time.


Now, for a few gripes about FCPX. I've been really supportive about it and for the most part have enjoyed it. But there seems to be a consistent problem where I'm left scratching my head and wondering why I cant change it. One of them is if you open the video animation window above the timeline, it is beyond reasoning as to why you can't right-click a keyframe and make it linear. It's a guessing game to change the keyframe to linear when you have a tracking history of 20 keyframes in the same location in the viewer window. The option should be like the motion where I can highlight all of the keyframes, right-click, and change all of them to linear.

I was impressed with premiere and how it handled keyframes. I liked the fact that I could select 4 keyframes in the effect editor, move my playhead to my desired location and paste the keyframes onto a clip at that point. I can't do this in FCPX. Paste effects doesn't accomplish this in FCPX or Premiere.

I know it's only one bad experience, but I think I'm going to start watching Premiere Pro tutorials. I feel like I've got a good enough grasp on FCPX and will continue to use it for basic projects, but keyframes and movements will move me to premiere.
