Motion tracking help

Hi all, hope everyone had a great Xmas.
I am having an issue with motion tracking and I will try my best to explain my problem as clearly as I can
Here is what I am trying to achieve.
Please visit this youtube video Canon Powershot SX30 IS -140X Moon Zoom Test - YouTube
and this is a still shot I just quickly edited in fireworks to show you the effect I am trying to achieve
http://img845.imageshack.us/img845/3148/motion.png
As you can see in the video, some parts of the moon go out of screen in some shots and the camera also zooms in and out of the moon, so I need the word "Business" and "logo" to increase and decrease in size in proportion with the moons size ( camera zooming in and out ) whilst remaining at the exact point on the moon ( as if the word "business" was built on the surface of the moon )
Which tutorial might help me? or if someone would be kind enough to explain how to do this, it would be greatly appreciated
Thanks in advance

Don't even bother to work with that video. Reshoot it. Next time, use a tripod and make sure the shot is consistently exposed, which at the moment, it is not. You apparently haven't even considered the problems trying to match your AE work with the camera auto iris.
And since he put it so well, I'd also like to quote Bogesian from a different thread, responding to someone who also knew little of AE, and wanted to learn what he or she thought would be a simple trick:
"After Effects is a kitchen. It's not a cookbook. And there is much more to using this metaphor than putting a frozen entrée into the microwave.
You have everything you need, it's just not given to you as a recipe for that specific effect.
The AE help system and the many tutorials that came with After Effects will show you how to animate text.
You will need to learn how to use motion tracking in the same way.
You may need to learn how to use the planar tracking system, Mocha, which is not for the faint of heart.
Like learning to make soufflé, you need the basic tools, fresh ideas, high quality ingredients and sufficient fundamental experience with all of the toolsm, techniques and ingredients. You will fail many times. Once you've discovered certain truths and universal, reliably repeatable steps, anything is possible within the kitchen.
Suggest you invest in ayof the many AE books by Trish and Chris Meyer or visit their website for several hours before you attempt to use the more advanced resources you can easily find online."

Motion 3 - motion tracking help

I am rather new to Apple Motion, so I apologize in advance for any novice comments or inquiries. That being said, I have extensive experience with video shooting/editing/graphics withing the Adobe family products. In this instance however, I am required to use Apple Motion.
My question is simple (I hope). I have a short video that has been motion tracked - selected a definable area on the motion and created keys frames to track the motion. I have then overlayed a graphic of a "dot" to highlight the motion of the initial video. The dot is subsequently matching the motion perfectly and is in sync with the underlying video. My question is this:
How do I add a "tail" effect to the dot - similar to a lens blur - so that the motion of the dot is highlighted a bit more. The concept is the same as having a "tail" on your computer mouse. I thought this would be easy.
More preferably - i would like to attach a paint stroke, as a light trail to the initial motion tracking (instead of the dot + tail). Apple's light trails are much more aesthetically pleasing and look better than the animated dot mentioned above.
In any case, I'm sure the above task is easily accomplished for an experienced Motion user, but alas I am struggling. Thanks in advance for your answers!!!

There is a trail effect in the filters, but I'm not a fan of it. Do do a light streak type of effect, I'd probably utilize the particle emitter.
Create an emitter from your dot (E), and set the speed of your emitter to 0. Match move the emitter to your tracked footage. Use the color over life parameters and birth rate to tweak the emitter and create your "light streak".
Specialcase has a wonderful tutorial that covers exactly what you're trying to do. Here it is:

Behaviors and Motion Tracking help

I just started using Motion today and am having some problems. I am trying to add an angel like halo effect over a head and am having trouble. I imported the clip I want to add the halo to into Motion via the Final Cut timeline. After it opens the clip in Motion I try to use "add behaviors" but it wont work when I click it.. I have the clip selected. I imported the clip into Motion but it's not letting me use behaviors for tracking.. It's also not letting me bring up certain windows like the Inspector. It will only show me the layers/media/audio and timeline windows. Please help. Thanks in advance.

I have no idea why it posted my question three times... I only clicked once.

3D Motion Tracking Error/Crash in progress [Urgent Help Please!]

Hey there!
I'm an video editor and I use 3D Motion Tracking a lot but recently every time I use it, it comes up with an error and says crash in progress,
It never used to do it and I can't seem to find any solutions to fix it.
Computer Specs:
Manufacturer: Toshiba
Model: Notebook
Processor: AMD E1-2100 APU with Radeon(TM) HD Graphics 1.00 GHz
Installed Memory: 4.00 GB (3.45 GB Usable)
System type: 64-bit Operating System, x64-based processor
So here's how I get to the problem. (I'll try provide as much detail as possible)
I import a mp4/avi file into After Effects,
Create a new composition with:
1280 x 720 (16:9)
Frame Rate = 30
Duration = 30 seconds
Resolution = Third
Advanced
Renderer = Classic 3D
(Boxes Underneath all unchecked)
Options:
Shadow Map Resolution = Comp Size
Motion Blur:
Shutter Angle = 180 Degrees
Shutter Phrase = -90 Degrees
Samples Per Frame = 16
Adaptive Sample Limit = 128
   3. Drag the mp4/avi into the composition to use it. (1.21 Seconds Long)
   4. Right click on it and go to Effect > Perspective > 3D Camera Tracker
   5. The 3D Camera Tracker initializes with these settings:
Shot type = Fixed Angle of View
Show Track Points = 3D Solved
Track Point Size = 100.0%
Target Size = 100.0%
   6.   Loads Frames 0% > 100% then as soon as the orange line shows up with Solving camera it shows this,
   and when I click okay it shows this,
   and then finally this,
   and then it crashes. that's the same process every time and it still comes up with this.
   Help would be appreciated !
   Thank you !

Try rendering an image sequence from your original footage then load that into AE and Camera Track the image sequence. Use the AME to or AE to render a JPEG or PNG image sequence:
It's important to know that some footage cannot be Camera Tracked. In order for camera tracking to work there must be a significant amount of fixed geometry in the scene. For example, if you have a shot of open water like this it cannot be Camera Tracked:
This shot also cannot be camera tracked successfully because most of the frame is moving:
If transcoding or converting the shot to an image sequence does not fix the problem and you don't get a frame rate mis match warning then you could have possibly not given enough memory to other applications in you memory and multi processor settings. Keep memory allocation for other apps in even numbers and make sure that you have not starved the dynamic link server that does camera tracking. If you have the memory 4GB to other apps is absolutely the minimum. If you only have 4GB then give 2 to AE and 2 to other apps.

Help with Motion Tracking and Masking?

Hi. First and probably only post here. I've got a bit of an issue....
I'm trying to create "snapshots" in my video that are created from masks which are then motion tracked and remain stationary. Here's a video of what i'm talking about... http://www.youtube.com/watch?v=9OhVAduuJc8
The problem I'm running into is that after i motion track the layer, select a null object as the target, duplicate the video layer, mask the object, freeze frame, and pair it to a null layer, the object does not remain stationary as the ones in the video do. Instead it moves WITH the null object and I cant figure out why. I've gotten a tutorial from the guy who made the video, however it's private so i don't know if you guys will be able to see it. http://www.youtube.com/watch?v=zY0QLrMCcGM
Either way, i followed the tutorial exactly and still to no avail. Are my settings messed up or what exactly is going on? Ive successfully done this project before but now that i'm using CS5, i'm running into these issues. If anyone has any advice i'd gladly try it out and return with the results.
Thanks so much for trying to help me out.

Yeah the null is still moving. Will freezing it lock the mask into place while still allowing the footage to play through? And how would i go about "freezing the null"?
I just dont understand how this person does it in the tutorial, and the mask remains in place. I know you probably can't watch the tutorial cause the user has it set as private, but as far i know his mask stays in place, but uses the null (while still moving) as a tracking device to keep the mask from floating out of control as the camera moves through the shot.
Sorry if I'm making this rather confusing. It's difficult to explain.
Maybe it might be easier to explain how you would obtain the result from the video I've posted? Keep in mind I dont have CameraTracker.

Need Help With Motion Track/Camera Tracking

I've been trying for several days to motion track 2 seconds worth of footage but I cannot get it. I've tried the AE motion track, 3D Camera Tracker, Mocha Pro, Camera Tracker from the Foundry, Boujou (could be user error with that though, cause I had never used it before), but I cannot get this shot figured out. Test - YouTube here is a link to the footage, I'm trying to track from frame 183-235 (where the guy is kneeling down in front of the box holding dynamite and everything is black and red)
Any help would be great, all I want to do is have an image attached to one of the boards in the background so it doesn't move.
Thanks!

Wow you have boujou? Thats awesome $10k, anyway looks like mocha should be fine for this as I don't see a ton of camera movement in that shot where you want to track. Do you know how to use mocha? If not there are tuts while working on that scene. Here's a few http://cgi.tutsplus.com/articles/advanced-motion-tracking-with-mocha-ae--ae-15231 and for various tracker apps including the built in one http://cgi.tutsplus.com/articles/26-tracking-and-matchmoving-tutorials--ae-7394

Need help with Motion Tracking-button in After Effects CS6

Hello I just bought After Effects cs6 and wanted to try ''motion tracking'' but I just can't push the motion tracking button. Is there anyone who can help me with that problem?
Responses are highly appreciated!

In order for the motion tracking buttons to become highlighted, you first need to select the clip you'd like to track in the timeline:

Help with linking a layer to motion tracked video

Not sure of the best way to describe this. I have a video with shadow in it which only moves slightly when camera pans a little.
Ive created a static image and removed the shadow in photoshop although could have probably done that using the clone stamp in AE.
However, the problem I have is that when the photoshop image is imported and I create the mask around the image where my shadow is on the video, the image is not tracked or linked to the video... How do I link it to the motion tracked video so that it moves with the video ?

Hiya
Yeah one below.. What you will see is the photoshop file, then the null layer followed by the original footage. In effect I need the photoshop image to track the movement of the camera as when I currently play the video, when the camera moves it looks as though a chunk of grass (the mask) is moving different from the rest of the scene.

I am trying to use motion tracking to have text follow a section of the background.The text box follows the motion path, but the text just sits there. What am I doing wrong?

I am trying to use motion tracking to have text follow a section of the background.The text box follows the motion path, but the text just sits there. What am I doing wrong?

Motion basically looks at the the source footage and it's timing (in the timing section of the Inspector) when analyzing for tracking. Filters are basically ignored by the tracker. Retiming actions, like time re-mapping, or retiming behaviors that are applied before the tracker should be used by the tracker. Did you change the timing after doing the tracking? If so this would also require you to re-track the shot. Understanding that you found a workaround, describing the effects you applied would help to explain why you ran into problems.
Cheers!

Motion tracking effect mask not working

I've no trouble with normal motion tracking, adding clip art to it and having the clip art track, etc. But according to the help in PE8, effects masks are also supposed to be able to be used. According to help:
You can also apply Effects Mask in the Motion Tracking mode.
1. Select a clip in the Timeline or Sceneline.
2. Select the clip, and click to enable the Motion Tracking mode.
3. Select any one of the tracked objects (shown by a yellow frame).
4. Select Edit > Effects.
5. Drag the effect you want to apply onto the tracked object on the Monitor panel.
The Effects Mask is applied automatically and the mask moves with the moving object. If you apply multiple effects to the clip, all the effects use the same mask.
I've done that and I get a mask but it does not move with the tracked object. Any hints?

Problem with motion tracking

I have Premiere Elements 12 64 bit on a windows 8 machine. I am trying to use the motion tracking feature. I am able to select an object to track and the resulting yellow rectangle follows the object as it moves through the scene. The problem I have occurs when I try to attach a graphic to the item being tracked; the graphic will not anchor itself to the yellow rectangle when dragged onto it, the rectangle does not turn blue. It appears the graphic is added as a static layer and does not follow the object. I have tried it using various video formats with the same result.

Thanks for the demo. Very helpful.
I am still not sure if it is the lack of contrast that is not giving you the best results. I tried to use a model with a light gray object to be tracked against a light blue background. Or, if it is those speech bubbles in contrast to other graphic types that are creating problems.
But, it is more than that. You did not see that yellow/orange box turn blue when you approached it with the speech bubble.
I found essentially one on one tracking when I used other than speech bubbles. But, whether speech bubbles or not, my yellow/orange box turned blue with the approach of the speech bubble or other graphic.
Here is what I would like you to try
a. Repeat what you did, but do not use the speech bubble. Use one of the other graphics under Graphics, maybe the carrot.
b. Repeat what you did , but use as source an object with more contrast against its background.
The main thing we have to work on is getting the yellow/orange to blue change as an indicator of what is supposed to be happening. Also, just back tracking to correct is not enough. If a try does not work, start with newly imported files to avoid any unexpected variables until we work out the situation.
Thanks.

Motion Tracking Problem

Hi im am very new to After Effects Cs4 and i am trying to do some simple motion tracking on some of my videos. When i try to place my track points on a high contrast spot and the click anylize my track does not stay in place and just pounces around the video. I have tried everything to fix this but just cant figure it out. If any one can help please leave a responce.
Thank You.

In CS4 a version of Mocha AE is already included. I would prefer this, if the
AE tracker fails on your shot.
Here are some video tutorials to get startet:

Also, I highly recommend to use Mocha in combination with my MochaImport tool.

Continue motion tracking

I did motion tracking and have a target layer attached to the motion tracking and it the target is masked. It is working great. I corrected some of the keyframes in the motion tracking and really fine tuned it.
Now, I would like to continue the same motion tracking with the same target for the rest of the clip. Can I continue the tracking? I notice that if put the playhead where I want it to continue and I go to the tracker panel and click on track motion, the tracking that I've already done comes undone and is no longer working.
Is there an easy way to continue the tracking where it left off? If that is not possible, is it possible to use the same target and do more motion tracking with another motion tracker?

I think you're hitting the wrong switch. When you open up the tracking (you have to do it in the layer view, of course), you should be able to use the Analyze Forward button for the tracker.
Here's a boatload of helpful information on Motion Tracking.

Probably Stupid question, but - how to remove motion tracking from a clip?

I've been playing around with the motion tracking feature, and think I may have come up with a way to make it work to highlight my now infamous "football"
However, I need to delete the motion tracking effect (s) that I've added to the clip so that I can start fresh. I cannot for the life of me figure out how to delete it!
This may be a very elemental question - and I apologize, but I cannot find the answer. I just cannot delete the original yellow tracking boxes -
Thanks in advance for your help!
Kim

To remove the Motion Tracking, just delete the graphic you attached to it. There's no need to remove the Tracking Object itself.
Although you can if you'd like. Just click to select the clip and then click on the Motion Tracking tool. Then right-click on the blue or yellow squares and select Delete.
