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.

MOTION TRACKING PROBLEM WITH ADJUSTMENT LAYER

Hi.
I'm trying to blur out a logo on a shoe, but I'm having some difficulty getting the tracker to stick to the logo. Can someone help me, please. Here are the steps I took:
1. I used Tracker to track a logo that I want to blur out.
2. After analyzing the layer, I went back to check the attach point frame by frame The attach point is centred perfectly on the logo on every frame.
3. Then, I added an adjustment layer, and used the pick whip to ensure that the position of the adjustment layer is the same as the attach point position from the tracker.
4. On the adjustment layer, I created an ellipse mask, applied a gaussian blur. But when I do playback, the ellipse mask is all over the place and not sticking to the logo.
Does anyone have an idea as to what I'm doing wrong? Any advice would be appreciated. Thanks, in advance.

To start off I always apply tracking data to a null then parent the null to the layers that should follow the track.
Make sure that you have picked the right target. Make sure that you've picked the right options. You should be using Transform as the track type. You should also do a quick Google search. There are a bunch of tracking tutorials out there.
If your null follows the object then you can parent the adjustment layer to the null. That should do it.

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 Jitter Problem

Using CS3, I am basically trying to replace facial features on individuals in some footage that I have. (replacing mouths, eyes, etc) I have been through numerous tutorials on motion tracking and have it down pretty well. I am tracking motion for both position and rotation, and the motion trackers are pretty dead on. However, after I apply the motion tracking and attempt to to pick whip other layers to this (I have tried numerous ways, nulls, directly to the tracked footage layer, etc...) it is very jittery, it follows the motion trackers just fine, but is very jittery...
I have found a few other with this problem, but no solutions were found. The only solution that I found was a suggestion to Average the null with a long expression that I had no idea how it worked. It there a quick fix for this? My whole 3 minute video is relying on motion tracking and parenting layers to the original footage... PLEASE HELP
also, would Mocha be worth getting, would it solve this issue?

Here's a post that links to some resources for face replacement using motion tracking.
If your only problem is that the motion isn't smooth enough, and you want to remove some of the detail in the motion, you can use the Smoother or the smooth expression method.

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!

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.

How to get Motion Tracking Mode to work?

How do I get "Motion Tracking Mode" to work? I click the icon and nothing happens, its like greyed out.

scouterbsa
Here is my check list for you to review regarding using Motion Tracking Mode in Premiere Elements 10 on Windows 7 64 bit.
1. You need a video and with enough motion in the object in it to track it. Color contrast between the object and its background can be important to success.
I created a DV AVI 4:3 in which I have a circle moving, and I have used a butterfly Clip Art from Premiere Elements 10 to track to track the circle as it moves in the video. In this example, you see the object only at 0 time.
2. Select/highlight the clip on the Timeline. And then click on the Motion Tracking Mode icon above the Timeline.
You should next see the following Motion Tracking dialog asking for a Yes or No to the question "Run
Auto-Analyzer to track moving objects?" Click No.
3. At this point, you will see a bounding box on screen. That bounding box should be placed using the mouse cursor on the object
that is going to be tracked, in this case, the circle. Resize and position the bounding box accordingly.
4. Once you have the bounding box on the object and resized, click on Track Object at the top right of the monitor.
The screenshot below shows only the before clicking Track Object at the top right of the monitor.
When that action is finished the bound box edges will be an orange yellow color. I have skipped over a screenshot
for the latter.
5. With the orangel yellow bounding box in place, next drag the Clip Art (in this case, Butterfly 02) from the Clip Art display area toward and into the orange yellow bounding box frame. The orange yellow bounding box frame will turn blue. That is the first sign of success.
Hit the Enter key of the computer main keyboard and watch the results. The Butterfly should track the circle's
movement in the clip. The duration of the clip and the continuity of the object's motion in the clip can be other factors.
If you do not succeed, try again with a different video clip (one with more movement and color contrast.
The above is a best case scenario. If it is speech bubbles that you are having problems with as well, we will deal with them next.
Right now it seems like you are having problems getting started rather than having a problem with a specific Clip Art that you are
using to track the object in your video.
We will be watching for your results.

Motion 3 - Motion Tracking and Match Move

Hi, I have no problem learning how to use motion tracking or match move because there's plenty of tutorials online. My question is, if let's say i motion tracked a clip to my original clip and half way through the movie an obstacle comes into the position where my motion tracked clip is. How do i make is so the obstacle appears in front of the motion tracked clip?
For example, take apple's motion 3 sample video.

The place where they put the GPS clip, if while the girl is driving she moves her hand in front of the GPS. How would we make it so that her hand appears in front of the GPS not behind it?
Any help would be appreciated,
Thank you

If I am understanding you correctly, it sounds like you are asking how to have an object that is part of the background layer appear in front of an object that you are going to composite in an match-move.
The only way to do that is to duplicate the background layer and move it in front of the layer you are bringing in, then create a mask around the portion of layer you want to keep (in the example you provide - the girl's hand).
You would have to go frame-by-frame and animate the mask to follow her hand - very time consuming but I don't see any other way.

Beginners Q: Motion tracking - Cannot move trackpoint

Hi all,
this seems to be simple: start motion tracking, move your trackpoint to the correct place that needs to be tracked.
Problem: I see the trackpoint, but cannot move it to its place.
The only way to do that, is to close AE, reopen AE & reopen the project, and continu moving the trackpoint.
This is only possible to do so for a few frames, then the trackpoint is fixed again, and moving is not possible anymore.
This topic seems not to be found on the internet, so I suspect a bug maybe.
Please help, it's driving me nuts...
any help is welcome...

VERY often, I cannot move object with the mouse cursor like text objects for instance.
Is there anything I can do??

Hi thx for replying,
If I remember well, the error message was a general OpenGl one.
I did have the error message not that often unfortunately.
Graphic card is updated to latest version.
It's very annoying I cannot drag&drop after a while...

Motion Tracking Won't Track Swim

I have a video clip of my son racing at a swim meet and I am trying to use the motion tracking feature but, I can't get it to follow him after he dives and during the race. I want to be able to highlight which one he is. Help?!

christelh
What version of Premiere Elements and on what computer operating system is it running?
What are you using as the tracking object?
Please supply more details and then I will customize a reply for what you want to do for the program that you have.
The following is a video tutorial demo'd with Premiere Elements 12.

Same principle with Premiere Elements 13/13.1, however users have been reporting problems with the feature in this version.
Looking forward to your details to help us help you.

Motion Tracking always 'wonders off'

I don't use after affects much as i do mostly website stuff. Sorry if this question may be simple/dumb, but i cant for the life of me figure it out ...
I have a video that I do tracking on.... simple x/y tracking... My workflow is: I usually like to do it manually frame by frame and use the assistance of the motion tracker to help me move something. i correct and move the tracker 'squares' sometimes as needed if the tracker is off, and then apply it to an image to move it. The funky thing is the whole motion tracking animation wonders off sometimes... I have this problem often and am not sure if i am setting the motion tracking correctly (like the 2 'boxes' that setup the inital tracking or the options). I think it is probably cause the center point of the tracking wonders off as i look back on it. But i thought it would/should always be centered in the middle of the inside box just as a reference. Didnt know it actually can move itself throughout the tracking ... I just want it to basically do simple tracking of the box to help me out without that point moving all over the place, and me having to maybe correct it for each frame....
Here is an attached file if you want to take a look at what Im possibly doing wrong.
Layer 63 is the layer i decided to track (blah sorry theres so much stuff) and i want to apply it to Layer 62, as you can see the animation wonders off. Not sure how to control the tracking.

There are some suggestions for correcting a drifting track that "wanders off" here: "Correct a motion track".
But first you really want to be sure that you've selected a good feature region (the area enclosed by the inner box). There are some suggestions for doing that here: "Motion tracking workflow".
There are some tutorials that walk you through the best practices for motion tracking here: "Motion tracking overview and resources".

Motion tracking issues

I am doing a rather difficult (for a beginner) sky replacement on a panning shot.
My first issue regards rotation. I've selected position and rotation for my tracking points, but after applying them to my sky layer, it becomes flipped upside down (rotated 190 degrees) and also out of position. Correcting the position is as easy as selecting all the position keyframes and dragging it to the correct starting point, but for rotation this doesn't work (it sets everything to one value). I want the first keyframe to be 0 degrees and for it to follow on from there with the tracking.
Secondly, because the camera pans quite far, I need to change the tracking points midway through as there are no two points I can use that are in the entire shot. Similar to the first problem, I find that when I do this it resets the position of the sky layer, sending it out of place and upside-down. I guess what I'm looking for is a way to apply the motion tracking to the sky layer without losing its initial position or rotation (or any other value for that matter).
Thanks!

Thanks a lot, I do have mocha but have never used it as I'm still in the early learning stage of AE. I'll watch through a couple mocha tutorials though and see where that gets me.
Regarding the matte, I was intending not to use one as there is so much foliage detail it seemed impossible to key the sky out effectively. Instead I was just going to multiply the sky layer and apply a gradient. I've attached screenshots showing the start and end of the shot, before and after I've done my best on it. If you know a better way I can do it, I'd be very grateful.
Cheers.

Motion Tracking - Match Move, getting messy edges around superimposed video

(Motion 3.0.2)
I'm using the "Match Motion" menu option under "Motion Tracking" - "Add Behavior" to superimpose a video over a flat screen in the shot. This is working great except for one issue. Around the edges of the super imposed video there is a flickering light that persists. NOTE: The flat screen does display a basic white graphic on it and initially it seemed as though this was leaking through. However, I'm not convinced this is the case as I've stretched the four corners well beyond the underlying white screen and the problem persists.
Pretty sure I went through the proper steps, i.e analyze etc. and the superimposed video does play fine, just the edges are not very clean.
Any feedback would be appreciated.

Thanks, I did set the "Render" to "Best", hit Analyze again, saved the file, went back to my FCP project which contained the file/clip, had to render again.....but got the same results, might be a touch improved, can't really tell. Maybe I'll start over and just cover the entire flat screen tv w/ the video to ensure that none of the white image from the tv seeps around the edges??
