Set Motion path to obscure a person's face in a clip

Hi all
Could someone tell me how to set a motion path to obscure a person's face so that they are unrecognizable? And, how do I obscure the face while leaving all else unaffected?
Please help with as much detail as you can.

depend on size of your blurr.. every 5th/10th/20th frame a new keyframe is probably enough..

Powerpoint 2008 on iMac - motion path

Does MS PowerPoint 2008 for iMac supports motion path? MS PowerPoint 2004 for iMac does not.
Please help...
Thank you.
Lsm

PowerPoint 2008 has partial motion path support. PowerPoint will honor any existing motion paths within a presentation. The custom animation feature offers the same pre-set motion paths that exist in Windows.
OpenOffice version 2.40 does display motion paths and lets you edit them.
Each and every time you save the document you have to visit Tools >
Options, check the load and save checkboxes next to "PowerPoint to
OpenOffice.org Impress/OpenOffice.org impress to PowerPoint" It seems to
be about 50/50 whether the file is saved correctly from OpenOffice.
"Correctly" meaning that PowerPoint will honor the motion path. I tried
half a dozen times with various shapes and motion paths. Sometimes it
works. Sometimes not. Wasn't able to figure out the reason or a pattern.
Haven't tried in OpenOffice version 3 beta, jet.
The next version of Microsoft Office will support VBA, and VBA supports motion paths, so maybe next time.

Particular 2.1.1. motion path + obscuration layer

Obscuration layer works fine when i use with particles that are coming from an animated emitter (light with animated path), but not when use the same path as motion path with a still emitter (which is at the same point as the starting point of the motion path). It looks good when i rotate the camera around. The 3d layer is in the middle of the particles, yet it wont obscure.
Am i doing something wrong, or is it just a bug?

Aaargh. *slams fist on the keyboard*
Seems like another one of those "set it to off, then turn it on again and it works fine" behavior Particular is known for.

Unable to set custom speed to motion path on Camera

This is a followup question to "Controlling speed along motion paths"
(Many thanks to Mark Spencer and specialcase for the their excellent insights getting me this far =)
After experimenting with motion paths and realizing they were indeed what I was looking for, I set up my project so that the camera would follow specific paths along 2d images. Everything worked perfectly until I tried to modify the speed along which the camera travels along those paths.
In the motion path, in the speed drop down menu, I can select Constant, Ease in etc.... all the way to Custom, but they work slightly differently than I expected: while before (ie. applying motion curves to objects as opposed to the camera) I was able to getting a diagonal line in the Keyframe Editor where I could modify keyframes using bezier curves to adjust the speed, now, choosing the various speed options appears to change the "Transform.Position.X" and "Transform.Position.Y" curves directly.
When I select "Custom", "Motion path" and Custom Speed" appear in the keyframe menu above the Camera drop down, but its curve appears only as a dotted, completely horizontal line in the graphing window. The "Transform.Position.X" and "Transform.Position.Y" curves also revert to horizontal dotted lines. If I try to add curves to the custom speed line, the X and Y curves remain horizontal and the camera does not move.
Is there some reason I cannot get custom speeds for cameras without losing my motion path data?
Is there some way to work around this?
Thanks again for all of your help,
Tim

I'm not sure if there is some setting I have wrong:
When I try this, while I am able to set keyframes, the motion path data is reset. (ie. the Transform X and Transform Y curves reset to 0).
In the Keyframe Editor, I can make new curves for the X and Y values and for Timing, but the camera does not follow the motion path, it follows the new x and y curves. Trying to get those curves to match the motion path exactly is a large hassle.
This might help:
If I apply the motion path to an shape rather than to the camera, everything works perfectly (the object moves along the motion path, and I am able to set keyframes for the Custom Speed curve with no problems whatsoever). If I then copy the motion path directly from the shape and paste it to the camera layer, the path appears as a red curve (as it should), but the camera does not move.
Is there some way I can upload the motion file so that you can see what exactly is going on?
Thanks again,
Tim

Set up a Motion Path to repeat?

Hi,
I have a project where I would like to have a motion path repeat until a specific point in time. Is there a way to specify this rather than copying and pasting until I want it to end? Thank you,
-Zack

Yes, you need to set the "After Last Keyframe" option in the keyframe editor.
-View the parameter(s) you want to repeat in the Keyframe Editor.
-In the Keyframe editor, to the right of the Keyframes is the animation menu, select After Last Keyframe and then set to repeat.
for more details, look here at the section titled "Parts of the Keyframe Editor"

CP5 - W7 - QUESTION - Motion paths, send project to other person.

Hi Me and my college work with the same CP files.
We have an internal flow
01-Preproduction
02-Post production
03-Ready for export
04-Exported and approved
I am responsible for the preproduction, creating animations and recording stuff
My college is responsible for cleaning and smoothing errors and edit text.
During the preproduction I create custom motion paths
When my colluege open the"moved" project files the animation works but he can not see my paths... it seems that my paths have been compiled to be a part of the project, and are no longer editable.
When working in a projectfile nothing should be compiled in to the project, everything should be editable. that is the reason to send a project file and not a compiled version to someone.
So what I want: I think that paths should be included in the project as editable paths when moving a project.
And I want to know if it is my lack of competence, a bug or an undeveloped feature that makes the paths compile into the project upon move.
Best Regards // Daniel

Hi Lilybiri,
It was lack of knowledge that led me to post this.
Actually, after reading your post and entering my colleges computer to investigate I found what the problem was...
He had the obect locked. Of course he could not see anything, because you can not even select a locked object.
Thank you for answering eaven the stupidest questions from my side.
Actually I think this whole tread should be deleted because it creates more confusion than knowledge for readers.

Using Light as Motion Path for Trapcode Particular

Hi,
I am trying to make an animation for a project, but I cannot figure out some things. I am trying to create the effect that a person is throwing money out the back of a car. I have the live shot of the person in the car, but I cannot get the money to behave how I want it to. I am trying to use the Trapcode Particular, but I can't get the particles to follow any motion path. When I set the settings to motion path, it prompts me to create a light. I create a light, but can't figure out how to make that light have an actual path rather than simply being a spot light. Please help! I'm sorry if I don't make any sense, please ask me to clarify if you need it.

Because you are doing it all wrong! If you wanted to use the Motion Path option in the Air physics model, your light would have to be exactly named like that - Motion Path 01. It's not what you want, though. I'm 100% certain of that. You are looking to create a conventional light emitter, which is a whole different thing. For that, your light should be named Emitter (or whatever other prefix you define in the plug-ins Options/ Settings panel). Then you must set the emitter type to Light. If you use spot lights and want your money to emit directionally, you need to set the emitter to Directional as well. Apart from that, Particular will use the light's color, cone angle and intensity to colorize and eject the particles. After that, you can animate the light in 3D space to whatever you need it to do.

Tween or Motion path for blank keynote with animated stars?

I create star particle effect from this tutorial: http://www.schoolofflash.com/2008/03/flash-cs3-particle-effect/ and got help from this discussion: http://forums.adobe.com/message/5518425 in order to get what I wanted. My code is:
var starsArray:Array = new Array();
var myTimer:Timer = new Timer(50);
myTimer.addEventListener(TimerEvent.TIMER, addStars);
myTimer.start();
addEventListener(Event.ENTER_FRAME, moveStars);
function addStars(e:TimerEvent):void
          var star:Stars = new Stars();
          star.x = stage.stageWidth / 2;
          star.y = stage.stageHeight / 2;
          star.alpha = Math.random() * .8 + .2;
          star.scaleX = star.scaleY = Math.random() * .8 + .2;
          star.xMovement = Math.random() * 10 - 5;
          star.yMovement = Math.random() * 10 - 5;
          starsArray.push(star);
          addChild(star);
          star.cacheAsBitmap = true;
function moveStars(e:Event):void
          for each (var star:MovieClip in starsArray)
                    star.x += star.xMovement;
                    star.y += star.yMovement;
                    star.alpha -= .01;
                    star.scaleX = star.scaleY -= .01;
                    if (star.scaleX <= 0)
                              kill(star);
function kill(star:MovieClip):void
          starsArray.splice(starsArray.indexOf(star), 1);
          removeChild(star);
However, I wanted to move the star particles around. The problem is that the star isn't on the screen, but is called in the actions in the blank keynote. I don't know what I should do next to get the result. I looked up online for tweens and motion paths but all i see is that they required the star to be right on the screen, I think? I also heard something about the compiled clip but I don't know how I should go about creating one and using it to move around the stars while it's animated with all the actionscript. All I wanted is for the star particles to float around the screen (on a path that I can draw out if possible).....

Each star is created in the addStars function. Its position is set in the first two lines:
     star.x = stage.stageWidth / 2;
     star.y = stage.stageHeight / 2;
So, to move each star to a new location when it appears on the stage, you'll need to change the x and y property values for each star. One simple way to do that is to use that same Math.random() function.
Try changing those first two line to:
          star.x = Math.random() * stage.stageWidth;
          star.y = Math.random() * stage.stageHeight;

Sometimes Circles -- Sometimes Bowen Knots: Motion paths made in Illustrator

I am doing a very meticulous animation in after effects CS6. To execute this project I made all paths in illustrator CS6. Think of the shape as being the Earth, and the motion path as being Earth’s orbit around the sun. I parented the shape (the shape that will follow the motion path; Earth) with a null object, the shape parented by a null object will then be parented by another null object (the path I created in illustrator CS6, at this point I paste the shape (motion path; Earth’s orbit) into Transform: Position.
The problem:
Some motion paths go around the originally made circle, in a perfect cyclical motion. This is what I want. Some motion paths go around the four paths in a square direction, resembling the command symbol on a mac keyboard, also know as the Bowen knot. I do not want this.
My questions:
How do I make every motion path (the perfect circle I made in Illustrator) to function cohesively and dissimilar to the original circle, and not like the command symbol? Why is the conversion doing this to some, but not all shapes?
Best,
Chris

Everyone – thank you to all who responded.
A personal thank you to Rick for spending time and executing a visual explanation.
It turns out my video wasn't published originally, if you need more information click: http://www.dailymotion.com/video/x1dba60_a-letter-1_creation
To answer your questions: the Earth's orbit refrence is a simile.
I understand the process seems irrational; I being with illustrator because I’m trying to find the exact angle to the center point, in addition to the size of the circle. In other words, a circle has four points, turn the circle the correct amount of degrees and one point starts on the center point (the black dot), the other half ends on the colored dot. The only way I know how to do that is by using a plug-in with illustrator (to get the angle from the colored dot to the center point, and the size of the circle), an analog of this plug-in is not offered in after effects.
My original question: why when I paste the circles (that are already made in illustrator) into the null: position in after effects, some give me a perfect circle, some give me a Bowen knot? I appreciate the suggestions about only in after effects, unfortunately the circle paths were already made in illustrator.
Best,
Chris

Motion path handles disappeared

I've been working in After Effects for a little while now and am having some of my motion path handles not appear when they should. I'm working on a slideshow and they seem to appear for all of my other pictures. What I do is go in between the start and end point of a path and move my picture away from the main (straight) motion path I created which usually creates a new keyframe on my timeline and inserts a point on my motion path with two handles I can adjust to make the path curved. This time it just creates the point on the motion path and keyframe, but doesn't allow me to make the path curved. It's really strange and has happened to me before. The way I solved it earlier was to remove the point where it wasn't working and insert a new one, and it would magically turn on, but that doesn't seem to work now.
I've only been able to find one other person that had a similar problem online, which was solved by going to view---->view options and enabling 'view handles'. This didn't solve my problem so I figured I would ask on here. Thanks in advance for the help.

That worked, although it's a few extra steps that I shouldn't have to take (and haven't prior to this). I held down alt by mistake at first and it only gave me one handle, but if I just tap alt and then click--->drag away from the point, it does provide me with a handle in each direction, which is what I was ultimately needing. Here is a screenshot of that layer although it's pretty standard.
When I selected a keyframe that was in between the beginning and end of the motion path, pressed G, and then hit alt it does exactly what I want it to, but usually it adds the handles automatically, and want it to always. This extra step is very annoying because I'm dealing with a lot of motion paths and plan to in the future as well.

Exporting or saving AE motion paths

Hello all,
A slightly odd request, and I have a feeling it's not going to be possible, but... is there a way to export or save motion paths out of AE? Just like bringing vectors in from Illustrator, but in reverse.
I have a very large comp which I'm moving a camera around. I'd like to take the camera's motion path into illustrator or photoshop and create artwork based on the shape, so that when I bring it back in and add it to the comp it fits the camera's movement perfectly. I know I should probably have doe it the right way round to start with, but the cmera move is/was based on too many variables to lock it down at that stage in the project.
Any help/suggestions greatly appreciated.
Thanks.

Copy&Paste works both ways... Motion paths can be pasted as masks and even as paths in PS and AI. Just make sure to set your clipboard options in AI to AICB, not PDF...

Motion path changes gets larger when copied to Shape Position parameter

Hello There,
Richard Gerard has been helpful, and well as other people.
I have sorta figured out how get a stroke to follow a motion path.
I (so far) am unable to get a shape to follow the same motion path.
My shape is a small ellipse commonly known as a circle!
I have seen this post - http://forums.creativecow.net/thread/2/959085, which is interesting,
but does not work. My shape layer consists of name, "Blue Circle", and two properties below that:
Contents and Transform. If i copy the path into the Transform-Position property the path is about 2
times bigger than the path I want to use, and does not start at the correct spot.
After reviewing the post above - I added a "path" to the ellipse in the "Contents" area, I can see the path, it is the correct size,
but the circle does not follow this path. If I try to copy this path to one of the position properties, no dice,
the path completely displaces the shape to the wrong coordinates.
I must be missing something basic here, but have yet to find out.
Any tips will help.
Thanks,
eholz1

The position path is offset because your Black Solid with the mask isn't in the default position. Both Anchor Point and Position must be reset. Parenting can also foul this up. Here's how to fix it.
First of all, before you copy and paste the path remove parenting and return the solid with the mask to it's default position by resetting Anchoe Point and Position. Now when you paste the path to your Blue Ball it will exactly match the path on the solid layer. Once the path is set you can redo the parenting and reposition the layers but you must include the blue ball. If it were me I'd create a null and make that the parent of the Black Solid, the Blue Ball, and the Map. Now you can animate the position of the null to scroll across the map and the blue ball will follow.
To match the timing of the stroke to the blue ball you simply drag out the right most diamond keyframe on the blue ball position until it matches the last position of the stroke.. That's all there is it. Your timeline should look something like this:
One last question. You have a non-standard composition size. It may not render correctly. What is the reason for the odd size. NTSC D1 Widescreen should be 872 X 486, It's acceptable to also have a comp that's 872 X 480. MPEG compression requires an even number of pixels so your 853 dimension is very likely to cause problems or be automatically resized to a standard frame size.

Custom speed not working in motion path behaviour of emitter

I am trying ot make a custom speed motion path along an open spline. Any amount of adjusting of keyframes and percentages produce no movement at all along the path. The emitter is stuck at the beginning of the path. All the other speed options work except for custom, in the motion path behaviour. What's going on here?

What's going on is a little complex.
When you first add a Motion Path and select Custom Speed, you get a "default" 0% - 100% over the life of the behavior [basically the same as Constant]. If you try to add keyframes in between, it can mess things up pretty good. The results you get can be unexpected.
If you "clear" the automatic default keyframing, then the Custom speed stays at 0% (there are no keyframes). If you move the playhead and change the Custom parameter, nothing "takes" since no original keyframe is set.
In order to make a Custom Speed on a path, you need to first, clear the default keyframing (on the right edge of the column, click on the disclosure triangle and select Reset Parameter). Then, set the position you want your object to start at and Set a keyframe. Then you can advance the playhead and move the Custom Speed control to position the object on the path.

Eleastic Easing Motion Path ?

Can anyone point me out how to set an Elastic or Bouncing movement to a motion Path? The only options I see are basic Ease In and Out . I would also like to have Ease In AND Out on the same movement. THanks in advance.

It's quite easy. I have a tutorial on how to do this at Filmmakingwebinars.com, in the 5-Step Tutorial section. More info than I'm willing to type here in a forum. But it's based on the ocillate parameter behavior, and some tricks it can do.

How can I create responsive motion path animation

I have an animate file that contains many amimations and one motion path animation. All animation elements of the animate file are responsive with the exception of the motion path animation which is not for some reason. Why does the motion path animation not repsonsive even though it is L, T, W, H coordinates are set as percentages?
Thanks

Hi, evetsrelfel-
There's no way to make motion paths responsive at the moment - we limit them to pixel-based animations.
Thanks,
