track motion versus event pan/crop

Ivan Lietaert wrote on 9/17/2007, 9:26 PM
I want a pan to start slowly , gain speed, and slow down again at target spot. I guess this is possible in track motion, under Keyframe type. Keyframe type is not present under 'event pan/crop'. As I want to put several still pictures with this effect on one timeline, I thought 'event pan/crop' would be the obvious choice. Not?

do an "event motion" search, there are a few recent threads that may help answer your question.

If I understood your question correctly, here is how to do what you want to do with pan and crop.
1. Set the event (still photo) for a long period...e.g. 15-20 seconds..
2. For the slow panning area, set the time between keysframes at a long period...e.g. 5 seconds.
3. For the fast panning area...set the time between keyframes at a shorter period...e.g. 3 seconds.
4. For the last slow panning area...again set the time between keyframes for a long period again.

Try this and let me know if it works.

Here would be a good start, it helped me a lot!!

Did you every get your tracking problem solved? What did you do to solve it?

Well, yes and no. Track motion allows fine tuning in terms of speed, but the keyframes are linked to the timeline, and cannot be linked to the picture, so if I move your picture around on the timeline, I can start all over.

Hmm, I don't have it in front of me right now, I could have sworn that the the keyframe markers would ripple with event if you enabled ripple for "All tracks, Markers, and Regions". I know I have done track motion before and was able to have the keyframe markers stick to the event even when I moved things around. Otherwise, it would be a pretty worthless feature, don't you think?

You are right. It works. Thanks for teaching me this.
Can you explain how to create a slow start, speeding up, and slowing down (exponentially) near the target place?

I've done something similar, Ivan, using Pan. I can't tell, did you choose to go with track motion or pan?

With pan, I took the approach Icdrdan described, spacing my keyframes (in the pan tool) to do this:
(a) I copied the initial keyframe and pasted it a few seconds off -> no movement
(b) I then inserted another keyframe a few seconds later, and at that point had zoomed in
(c) I then inserted another keyframe a few seconds later (by default it was the same, iirc, but you could always copy the second and paste it) -> holds the zoomed shot

etc

I'm still new to this, haven't tried keyframe movements with Track Motion. I've used Track Motion to frame my entire track to fit 16:9, knowing that all the events are 4:3.

Well, in track motion, you can do it, and the keyframes stick with the picture, so you can move the on the timeline if necessary. The advantage of track motion is that there you can select different types of keyframes (slow, fast, smooth....). The definition of these types in the help section is rather cryptic, and the result is rather ambiguous. I would like somebody to clarify these options in a better way. I've been experimenting with them, and see barely a difference myself.

I've used the track motion options, but only when I wanted something to happen instantly (as in turn off smoothing).

I think I would go with dogwalker's approach, that is, add multiple keyframe markers to force whatever speed you want for the movement. I bet you could get the effect you want with only a few markers.

The settings for linear, fast, slow, smooth, sharp, and hold apply to the timing from one keyframe to the next. Linear means that each frame will have the same amount of movement. Fast means that there will be more movement at first, then less and less as the next keyframe is approached. Slow is the opposite with little movement at first, then increasing speed. Smooth means that it starts out gradual, gets faster, then slows down to gradual again. Sharp i'm not sure about. Hold means no movement at all until the next keyframe, then a sudden jump.

The smoothness percentage refers to spatial positioning in the frame and the path the movement takes, and not the speed with which the movement happens.

Thanks, Chien, this really helped.

You're welcome, LOL.

I posted it because you didn't seem to see the link to it that I posted earlier.
