Angle issues

I'm almost ready to render out a project invloving some even/pan crop work.

Essentially what I'm doing is changing the angle and positioning of the event over several keyframes about 1 - 2 seconds apart.

The problem is that this works for the majority of the time, but on some of the changes it's not a smooth transition from one keyframe to the next.

Admitedly 90% of the transitions are smooth as can be, but the remaining 10% jump from one angle to another in the bat of an eye, which completely destroys the effect I'm trying to achieve.

I've checked the settings at, directly before, and directly after the keyframes in question, and everything seems to be fine...

smoothness is set to 100% in all cases, and the appropriate angles, and positions have been set...

I have noticed that if I look at the shape of the dashed setup box, used to position the viewable area, it looks skewed itself, like an angle or rotation is being employed, even though the angle box reads 0.

I've also tried deleting the keyframes where the problem occurs and then rebuilding them, but nothing seems to make a difference.

Any suggestions?

One or more of your keyframes is incorrect, missing or not needed. Your best bet is undock the pan/crop work area then drag it up and away then make it large so you can see better than nudge (the diamond on the smaller timeline) for the key frames where the problem is or add/delete some.

With just a little practive you can get very smooth panning regardless what angle you want. Does takes some practice. See my tutorials #14-15 for how smooth you can do it. You can even pause, slow down, speed up, zoom in and out as you pan.

I think you misunderstand what I'm saying...

I have at least 100 keyframes, and most of them work. I have been able to acheive great, smooth, results for 90% of those keyframed moves, there are just a few towards the end of the event that don't act right.

I never work with event/crop while docked,a nd the window is expanded tot he size of the screen, and I also zoom in on the keyframe timeline to get a good look at what's going on. There is nothing to indicate a problem, except for the skewed appearance of the dashed guide that lets you know what will be viewable at the keframe. Remember that this dashed guide is skewed, slanted even though the angle on the same keyframe is set to zero...So there is obviously a bug issue here, right?

There are no extra keyframes or missing keyframes, or keyframes with incorrect information, yet when I playback or render certain sections still do not cooperate.

I have been able to put a band-aid on the problem by adding keyframes before and sometimes after these problem areas where I changhe the angle to what it should be at the begining or end of the previouis or next keyframe. This way the system seems to correct itself by not doing a rotation and a move at the same time, which is truly peculiar because almost the entire event is full of the same keyframed moves and rotations, and most of them work fine.
