Motion tracking: matching two tracked elements

Hi all,
In slightly over my head... searched high and low... but I am stuck.
I have two video elements in a composition, both VERY similar, but they don't track perfectly.
What I tried to do was taking the tracking data from one element, and subtracting the tracking from the second element in expressions (to get a delta), and then apply the difference to the anchor point of the element. This did not work... as I expected.
I have two good tracks, but I can't figure out how to get these tracks to work together (they are tracking the exact same point) to match them. Is this a match move problem?
Please help. Thank you.

Thank you Mathias,
I can't stabalize because the shots both pan.
Imagine a dolly shot... moving smoothly though a scene. That is shot A
Imagine a second dolly shot, on the same track, of the same scene. That is shot B
Imagine that the dolly operator could not perfectly dolly the camera for each shot (how could they?).
But they are close.
I can pick the exact same track point on the dolly shot... so that gives me data on each dolly shot.
As you can see, there is nothing to stabalize. Both shots are stable... they just track differently, slightly.
I am not using mocha.... this is a perfect 2D track situation.
I tried vector subtraction in expressions, subtracting tracker A from tracker B... that number should be the difference between the dolly shots, yes?
Now, if I use THAT number to offset one of the shots... that should cause them to realign, yes?
I feel I am close...
I am using the sub(v1,v2) expressions function.
This is probably simple, I'm just being thick headed about it somehow.

Thanks for the reply.
I checked the link that I posted back in post 3 of your thread. It is working with at least Firefox and Chrome.
ATR Premiere Elements Troubleshooting: PE12: Motion Tracking/What To Use To Track Object?
What browser are you using?
The blog post contains significant information related to Premiere Elements 12 Motion Tracking. But, if you cannot access it for some reason, then we will need to troubleshoot via communications in the thread.
SG has asked if you are able to create Motion Tracking effect using one of the graphics included with the program. We will watch for your response to him on that question. Please include in your message to him whether you can obtain your file to track the object using Organizer Tab or Project Assets routes as well as Graphics Tab.
The following is an excerpt from the blog post referenced....
SOLUTION
Various tutorials and online comments have pointed to places other than Graphics Tab where objects can be selected and used to track the moving object in the video when the Motion Tracking workspace is opened in the Expert or Quick workspace.
Organizer Tab, Expert or Quick workspace to access Elements Organizer 12. Cascade Windows and drag a video or photo from Elements Organizer into the yellow track box of Motion Tracking workspace.
Project Assets, Expert workspace. Drag text, video, or photos from opened Project Assets into the yellow track box of Motion Tracking workspace.
Graphics Tab, Expert or Quick workspace. Create a png file (graphic) or prtl file (text) and place it in Clip Arts in the Program Files of the program to have a permanent resource. Then from Graphics Tab, drag the newly created graphic or text object into yellow track box of Motion Tracking workspace.
Thanks.

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.
http://www.youtube.com/watch?v=BwezKN_hFF4
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.

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??

Premier Elements 13 on MAC. trying to use motion tracking. immediately get error "the media file seems to have an invalid entry in the catalog. Please rename it for use."

Anyone resolved this issue? What is the "catalog". All I did was import a file (1080/60) and get started. Everything else seems to work fine.

Assuming you're not shooting in 3D mode, I'm not sure why this is happening.
As long as you're not shooting in 3D mode, this is a standard AVCHD camcorder, which I've done lots of motion tracking with.
Since you manually copied the file from SD card rather than getting the media using Premiere Elements' tools, it is quite possible you grabbed the wrong file. Try this: Plug your camcorder (with SD card in the cam) into your computer via USB and set the camcorder to VTR/play. Then go to Premiere Elements' Add Media/From Flip or Camera and use that tool to get the video from the camera to your computer.
This should resolve your invalid catalog entry issue.

Premiere elements 13 motion tracking does not track

Motion tracking in elements 13 doesn't work

renemikkelsen
The frequency of the Adobe presence in this forum is undefined.
Since you have not been able to define a difference between image to be tracked and tracking object in the cases that worked and did not work, what do you think about the following idea to define you situation in terms of Premiere Elements 12/12.1 vs 13/13.1 Motion Tracking feature.
You could download and install the tryout of 12 from the following web site and compare the performance of your 13 Motion Tracking with 12's with the same object to be tracked and same tracking object. You would not have to uninstall 13 to do this. Just use one program at a time.

I've to match move a filter (like distortion-bulge) o a moving object using motion tracking, but i've nit able to perform it.
(I want to distort an eye in a face that moves it)

Motion tracking in Premiere Elements 7

Is there any way to do a motion track in PRE7? I've seen it used in Final Cut Pro and PPCS4 so was wondering if there was any other way of doing it with out using key framing?

Here's another ask of you Paul.
I've also seen a tutorial on a guy adding a glow to a wedding shot that he had. It was a shot of some of the grooms party in a church I think and also a shot of the grooms party outside the church. The tutorial showed how to bring up the whites on certain areas of the images to glow out the whites and have them shine through ... if you know what I mean.
I forgot to bookmark the tutorial so just wondered if you knew (again) where it may have been from. A big ask I know but I thought I'd try just in case.

Premiere Elements 9 Motion Tracking Auto to Manual

I seem to be having a problem where I can't switch back over to manual motion tracking.
Okay, so I started up the program and one of my clips required motion tracking. So I added it and a box poped up if I wanted it to be auto motion tracking I said yes, to see how it would do. Of course it wasn't to great at tracking the object so I turned it off then back on it went straight to auto without asking I thought "maybe it is the clip?" so I tried it on a different clip straight to auto again no popup. I then thought "Perhaps a new project?" Same result. "Turn the program off and on?" You guessed it same result so how do I turn it to manual motion tracking?
Much Obliged

Sorry that replacing the Asset did not work.
By "loop" I meant when a setting cannot be undone, and regardless of the setting, reverts to a previous setting.
As I have not used Motion Tracking in PrE (I use AE for this type of work), I do not know what the next troubleshooting steps would be. I know that Steve Grisetti and Neale, both have used it, so maybe they will have a next step for you.
Good luck,

Motion Tracking - Match Move

It's yet not possible to send a clip from FCPX timeline directly to Motion 5.
If I want to use "Analyze Motion" and "Match Move" everything must be done manually, what is a pain in the ???.
No workflow at all.
Does someone has a workaround, if I want e.g. to make a Title "Match Move" to a previously "Analyzed Motion" of a clip directly from FCPX's timeline?

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??

Why don't I see a dialogue box when I click on Motion Tracking?

My project's working fine, and I'd like to add a Motion Tracking effect. When I click on the MT icon, nothing happens. I've tried Auto Analyzing the clip first; no difference.
PreEl 10, Win 8.1, i7 16GB.
Thanks for any help!

Dave
I have not finalized all the details. I am double checking and triple checking between Premiere Elements 10 and 12 on Windows 7 64 bit and Premiere Elements 10 and 12 on Windows 8.1 64 bit.
The first rounds revealed the following
a. Your video is 1920 x 1080 @ 29.97 interlaced frames per second with Scan Order = Top Field First. The video compression is probably AVCHD, and the file extension is definitely .mts. Based on that information, I am setting all projects to the project preset
NTSC
AVCHD
Full HD1080i30
b. When I import your video into Premiere Elements 12 Windows, the Motion Tracking icon above the Timeline immediately "lights up". (There is no colored line over the Timeline content.) With the clip definitely selected, if I now click on the Motion Tracking icon, I get the Motion Tracking dialog to which I click "No". In the Motion Tracking Mode, I click on Add Object to get a bounding box that I position for the Object (dog) in the video. Then I click on Track Object. After the program does that, I get a orange/yellow frame around the select object in the video. When I drag a clip art from Clip Arts into the screen and near the orange/yellow frame, the orange/yellow frame turns blue.
c. When I hit the Enter key to place the keyframes and get the best possible preview, 99.9999% of the time, the clip art tracks the dog in Windows 7 64 bit. But, when I go through the whole business in Windows 8.1 64 bit, everything is the same as in Windows 7 64 bit counterpart, BUT the Clip Art is not tracking the dog.
That is what is taking the time to define.
Three focus points, I am not sure in or out factors
1. First time around in Premiere Elements 10 Windows 8.1 64 bit Motion Tracking, there were two notifications of Activation processes being done related to Motion Tracking. So, I would ask "Are you working with Internet connection On?"
2. Are you setting the project preset to match the properties of the source file that you are using in the Motion Tracking feature?
3. Motion Tracking feature is in 10 and 12, but never in 11. Supposedly, 12 Motion Tracking is an improvement over 10. So far I have not seen evidence of that here.
Nonetheless, you seem to be stopped by the Track Object after Add Object and placing the clip art, and have not gotten to these end results yet that I am describing where the clip art tracks or does not track the object. Is that correct?
There is not a great amount of motion in the clip and the color contrasts are not pronounced. I have tried different clip art files with different colors. So far, same result.
More later.

Motion Tracking Ping pong ball

I'm superimposing a ping pong ball into live footage of a match but with the actions acting the hitting.
What do people think is the best way to do this?
I was thinking maybe its best to put the 'ball' under a null, motion track the null and animate the ball underneath for scaling and position.
Maybe motion tracking isn't an option and I should just animate the ball movements?
Has anyone done this or may have any possible suggestions?
Thanks!
SG

Make your life easy, hand-animate it. Pingpong is a fast game, resulting in lots of motionblurred elements and it will be a nightmare to track. You'll waste a lot of time on fixing a poor track that you could have spent refining your animation to begin with....

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.
