How do I motion track a facehugger?

Hi guys, girls, anyone else,
I've made video footage of me shaking around like I have a facehugger on me. I also have a facehugger model in maya. I've heard about motion tracker software and I'm happy to incorporate it, so anyway I was wondering if anyone had any quick tips or advice on getting the facehugger composited correctly onto my face. I was thinking about first attaching the facehugger to a model head and then painting it green to remove in AE later. My main reason for thinking this was that (as well as a front shot) i have a side view shot of me being attacked by it, so in the side shot i don't the legs furthest away showing...
I'm a total newbie to after effects so any help would be appreciated
Thanks
Rory

That's not an easy task, especially for someone just starting out. It involves motion tracking, possibly 3D camera tracking, bringing the motion of the camera into Maya and occluding any parts of the mask that would be hidden by your face, then composite the two together. This is not something that can be covered in a single post. This would be more like a 10 page white paper. Basically, you track the face, import the tracking data into Maya, mimic the lighting in the shot in Maya, and then overlay your rendered mask with your footage.
First, you must get very familiar with AE Basics. Go through as much as you can. Then you need to read up and watch tutorials on motion tracking in AE and Mocha. There are lots of Mocha tutorials on the Imagineer site. You need to learn all about how Mocha tracking integrates with AE, how to track, how to mask or do roto. You'll also need to learn a lot about After Effects motion tracking to understand the process . Once you get a handle on that you can start doing some basic compositing. Look at tutorials like this one on Face Replacement or this one on eye replacement. Those should get you started.
Get to the point where you can do something like either one of the last two tutorials and then start poking around the Maya forums to learn how to insert a head in your mask and render only the front side (facing the camera view), add motion tracking data from AE or Mocha, or any of a dozen other tracking programs, to Maya, and then you'll be ready to start working on your actual project. I'd guess 10 to 20 hours minimum of research and experimentation and you will be ready start on your project. If a client came to me with this kind of project I would tell them it would take about two days in post per 10 seconds of footage to pull off a believable shot like the one I think you want to do. VFX of this kind are not and never will be a simple 1 click 1 plug-in solution.

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.

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.

How do I motion track just like the Plugin CameraTracker 1.0?

On the plugin CameraTracker, it automatically detects points that can be motion tracked, and it does it very well. What got me thinking, is that it also carries on tracking when a tracking point goes out of screen.
Here's an example:
I am using CameraTracker. As you see, this is the beginning of the clip, and what happens in this scene, is that the camera just fly towards the jungle.
If you see "Hehe", there's a green cross, and that is where the "Hehe" is tracked to. That red box is the null object.
Okay, so when the camera is flying towards the jungle, it passes that green point. And as it passes, it does not stuff the "Hehe". That "Hehe" stays in place as if it was in this Minecraft world.
It says in place, even though the cross has gone out of place.
BUT, if I use the Adobe After Effects built in motion tracking, and just want to select that point where the "Hehe" is, and I begin tracking, it goes pass then green cross, then that tracking box goes everywhere.
How do I do this so it's like CameraTracker? I want to do this using the default After Effects Motion Tracker.
If you cannot understand what I'm trying to explain, let me know what part you don't understand.
thanks.

Could you give me an example of "where you stop the track then move the track point to another spot in the image", using my picture?
What's the difference between CS6 Camera Tracker, and CS6 Motion Tracker?
And for the Camera Tracker plugin, I can only seem to track ONE part. If you see the image, the words are like in one part of the scene. If i were to put a word in a tree, it would look stuffed up. The word wouldn't be tracked onto the tree. It would be tracked on the sand instead.

How to I motion track between changing scenes

Hi i want to motion track heads on to people but the camera keeps changing back and forth scenes. i would like to do this in motion, but i do have FCPX and Adobe After Effects if there is a way to do it there.

I'm not sure what you mean by "changing back and forth scenes", does it cut between scenes or pan back and forth? Since we can't see your footage, it's hard to give specifics, but here are some ideas:
-Break the shot up. Use in and out selections and anlyze in sections.
-Use the offset track option. After you track a "good" section, when the tracker fail (or you stop it) check the Offset checkbox in the Inspector. then find something that has similar horizontal or vertical movement from your subject, which should be at about the same distance as your subject, repostion the tracker and continue to analyze.
I would really suggest reviewing the documentation on using the tracker. If you can be more specfic about your shot, or post a sample, we might be able to give you better suggestions.

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 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."

How to use a webcam with Labview8,Vision 8 in motion tracking?

I have a webcam and Labview 8, Vision Assistant Module 8, NI IMAQ for USB Cameras. What I concern is how to use a webcam in motion tracking? Should I just use Vision assistant or use it in combination with Labview? Do I need any other support?

4,
Thanks for your post. Vision Assistant is a good software package to prototype your system, but it does not give you access to all Vision methods. LabVIEW is much more powerful allowing full access to Vision. You may want to use Vision Assistant to play with the algorithms (you can use your mouse to set regions of interest, etc) and then once you find the methods and parameters that work, implement the code in LabVIEW.

How to motion track footage onto other footage

not sure if my title is worded right but I have footage of a bus driving by with an advertisement on the side.. I want to take some footage I have of myself and put it on the bus advertisement in the other footage using motion tracking.

Any normal corner pin tutorial will explain it and in fact one of the basic tutorials for mocha AE covers tracking a poster onto a London city bus...

Is there a good motion tracking plug-in for FCP-X?

The question is in the headline: Is there a good motion tracking plug-in for FCP-X?
You know, like when I want to blur out, say, a license plate number on a moving car.
I know of no plug-ins for FCP-X that will do this. Surely there's one out there.
And since you can't just export a sequence to Motion (like you could in FCP 7), how would one achieve this in FCP-X?

R&B wrote:
… And since you can't just export a sequence to Motion …
instead of selecting a clip or sequence in FCPX, you set the in/out points in the Export/Send it to Compressor dialog.
the exported mov can be tracked in Motion5 …-
aaaand finally re-imported into FCPX.
… not exactly as convenient as in the old FC/p , but the tracker in M5 offers, imho as a hobbyist, superb results.-

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.

Motion tracking in PE12

How can I only get text to show during motion tracking? - I don't want the animation which is included!
Best regards...

SG
On what Premiere Elements version?
I am talking specifically about your second option for this Premiere Elements 12 Motion Tracking question....
The other option is to create the title BEFORE you do your set up your Motion Tracking, and then just drag it from the Project Assets panel onto your Track Object.
I see no opportunity to get to Project Assets to get at the title/text without shutting down the Motion Tracking workspace. But, if you insist it can be done, we will give it another look with Premiere Elements 12 on Windows 7 64 bit.
One alternative that does work (that you did not mention) was
a. create a text title
b. save the text as a .prtl file
c. place the saved .prtl file in the path
Local Disc C
Program Files
Adobe
Adobe Premiere Elements 12
Clip Arts
Common
and in the Common Folder place a folder named something like My Text, with My Text Folder containing the .prtl file.
That My Text category and the text file in it will show up in Graphics from which you can drag the text to the screen at the appropriate prompt in Motion Tracking scheme. In this approach, the text becomes a permanent and reusable resource under the Graphics Tab.

There is no motion tracking position selection box.

Hi. I'm using a Mac. 10.8.5. I opened the new AE 2014. I make a new composition 1280 by 720. I open a short clip. I play it through once. I go to animations and select "Track Motion" I select "Track Motion" in the "Tracker" box on the bottom right on the AE program. No motion tracking boxes appear on my clip. I cannot select a point for tracking. Please, how can I fix this?

Thanks. I was almost ready to uninstall it and re-download it when I noticed I might be using the older AE CC which had it's icon on my dash board instead of the newer AE 2014. So I opened the newer one from applications and everything works fine. Thanks you for your assistance.
