Motion tracking: corresponding to the two elements of caterpillars

Hi all

In a little over my head... searched high and low... but I'm stuck.

I have two video elements in a composition, both VERY similar, but they do not follow the perfectly.

What I tried to do was taking an item tracking data and subtracting the follow-up since the second element in the expressions (for a delta), then apply the difference with the anchor point of the element.  It did not work... as I expected.

I have two good tracks, but I can't figure out how to get these titles to work together (they are tracking the same exact point) to match.  Is this a problem of displacement of the match?

Help, please.  Thank you.

No, made no sense. I'm not taking about stabilization far from the shakes or jitter in the shot. I mean to get rid of all the movements of dolly temporarily. Review the tutorial. I first ask (1) stabilize what makes the scene completely static (most don't move no dolly) such as the image progressively moving out of the frame. Then I apply 'move' (2), such that the initial movement is reintroduced, and you are basically in the original shot. (Which I can stabilize (3) in a third stage). You just have to jump (3) and use the path of the layer itself to (1) and the track of the other layer for (2).

I hope this makes it more clear. Just think of stabilization is not as "do the smoother camera movement" but as "applying to the reverse of a movement of caterpillars.  You can use it to smooth out a camera movement, but sometimes it is also logical in other scenarios.

With your expression, you do exactly the same thing, by the way. It says something like

"Movement Tracker A - Motion tracker B + Position.

It's like to stabilize the position in regard to section B (subtract his movement) and move according to A (adding his movement).

    I scanned the two elements of a brother MFC - 240 c printer all-in-one to computer. where can I find documents

    Hello MichelleOZ,

    Items scanned by scanner are stored as Images (usually from the MPEG files) so I would look in the pictures folder. Otherwise if you remember what you call the files when you saved them you could also search for them via Windows Explorer.

    File photo:

    1. open Windows Explorer

    2. look in the folder list on the left side of the Windows Explorer window

    3. Locate the folder of photos

    Search:

    1. open Windows Explorer

    2. place your mouse cursor inside the Windows Explorer search box (upper right side of the Windows Explorer window), and then type the name of the file that you want to search

    3. Windows will now search for the file.

    4. once found, click on the file to open it.

    You are at the mercy of the percent sign. By setting the width of .entry as 100%, you lose the fine adjustment possibility which pixels gives you.

    div.post div.entry, div.entry div.post-chat - fifteen, div.entry, div.post-chat - three div.entry div.page {/ * added div.post-chat - 15 * /}

  • Want to only two elements of the page without a space between them.

    I give a broader and more generic framework to an earlier application seeking a broader response.

    I want two elements on the page without horizontal between space. (Don't ask why!) One is a contant, say ' * ' so I made a single display element. The other is the label of a numeric field that is referenced in the error messages generated by the ARF.

    Call the label LABEL to make this easy. So, I want to see {noformat} * {noformat} LABEL. I don't want to change the label of "* LABEL" because ARF refers to "* LABEL" in error messages. I want to just fix the two elements on the form. This must be something easily done in the APEX, right?

    (For the initial application, see asterisk desire by a label point of page without space between. .)

    Thank you and God bless you,

  • Motion tracking and export

    For work I was in charge of some intuitive ways to effect counter.  Things I would normally do in After Effects, but they would have done as in first CC 2015.  Most of them come down to it, they gave me a first CC 2015 file with videos that have a need for the cover of the inverter or additions to them.  They then gave me still images or videos that contain what is necessary to cover/replace objects in the scene.

    For example, there is a license plate in a shot that must be replaced with a different license plate that they recorded on videotape.  I have hidden opacity the additional cost of the new plate of video and resized so that it matches the plate of cars.  The images of the car has been done with a steady cam so there are several tiny motions.  I went by adjusting the position of the new plate image by image, but still does not seem smooth.  In older versions of first I would have corrected it with the CAP mocha, mask of garbage or exported to AE.  I have not been able to find similar tools for this first CC 2015 and tutorials all seem to point towards AE (as I said, their desired method is not intuitive).

    My other question is much simpler.  What would be recommended for video uncompressed export type?  They asked he be sent as prores 422 or equivalent, and since I was on a PC I can't export it.

    In all that I feel that I'm starting to see more limitations with CC 2015 on my cs6.

    After effects 3D Motion Tracking is certainly the simplest method and the best on this one.  I'm curious as to why someone might stop you from doing the job properly?

    The PC equivalent (actually higher) to ProRes is DNxHD.

  • Need some advice on the form element values?

    Hi all

    I have a problem with the site that I am developing. Its a site of e-commerce for a memorial Masons. For each product/memorial there are several elements, menu drop-down menus and text fields to retrieve the necessary information, there is also a 'total' who, as customers make their choices, the amount of each item is added to this total. My problem is, on the two elements "engraved_designs" and "sandblasted_designs", I need to calculate this amount, but also I need to get the code of the design chosen for back-office reference. I can't use the price and code in the "value" attribute, that you stop the calculation of work function. So, how am I to get the amount to be calculated at the same time as being able to recover the chosen code when you submit the form?

    http://www.milesmemorials.com/product-GH54.html

    It's exactly the same principle.

    $engraved2 = explode (' #', $_POST ['engraved_designs2']);

  • How to get the control to one of the text element?

    Dear people,
    I have two items of text to say TEXT_ITEM5 and TEXT_ITEM6.both values entered in the text elements must be equal.else that an error message should be displayed and two items of text should be cleared.so that I wrote the following code in WHEN BUTTON the shutter as.
    If :block3.text_item5 <> :block3.text_item6 then
              c:=show_alert('ALERT21');
               :block3.text_item6:=null;
              :block3.text_item5:=null;
                       raise form_trigger_failure;
    end if;
    Its almost works well, but after having erased the text in the two elements of the control text should go back to TEXT_ITEM5. I even tried GO_ITEM but is not working properly.pls help me with suggestions.


    Regarding
    Vids

    Hello

    If the value of two text element should be equal so why give the possibility to enter 2 text boxes? Enter 1 text and WHEN-VALIDATE-ITEM trigger of this element, assign the value to the other text element. And if you still need the old way, then you must write the GO_ITEM integrated before the RAISE FORM_TRIGGER_FAILURE statement.

     IF :BLOCK3.TEXT_ITEM5 != :BLOCK3.TEXT_ITEM6 THEN
       C := SHOW_ALERT('ALERT21');
       :BLOCK3.TEXT_ITEM6 := NULL;
       :BLOCK3.TEXT_ITEM5 := NULL;
       GO_ITEM('BLOCK3.TEXT_ITEM5');
       RAISE FORM_TRIGGER_FAILURE;
    end if;

  • Drag the item over the other elements

    I have a canvas where I drop from several textarea. As I move things moved around, they hang out or drag under the other items previously ignored. The last point of fall passes on all the elements previously ignored. The sooner the ignored items disappear below. The question is: How do the point I'm always dragging display above the other elements?

    Here's a quick example. Drag and drop the two items in the list to the canvas. Then drag the two elements around. The second element that you drag and drop will always overlap the first item when you drag. The first item will always appear below. It is a problem because if you have a mouse until eventlistener on the first point, it will be called, but won't run correctly function, at least with regard to the update of the display and resizing of the dragged item (height, width, backgroundColor, etc.). I think it's a bug.

  • Is it possible to use the motion tracking to add nice looking titles or titles of movement (not only the ridiculous info bubbles)? Or better yet, is it possible to integrate tracking movement with your own bunk graphics? (using first 14 elements)

    Issue of title

    Yes of course. (I even show you how to do in my book 'Cool Tricks & hot tips for first Elements 14'.)

    Just make sure that whatever graphic you want to use is already in your project assets before you begin your Motion Tracking.

    Once you are in the Motion Tracking Workspace, the active panel of the project appears at the top right of the interface, and you can drag any graphic, video or title pre-created on your path of Motion.

  • Dance of the Rotoscoping in After Effects with motion tracking?

    Hello!

    How can I copy the movements of real popular dance to a video into a cartoon character using rotoscoping/masking/motion tracking in AE?

    Example:

    Neytiri dance rotoscoping/animation at the beginning still very rough - YouTube

    Tracking and Rotoscoping in After Effects: dance-2014 Jayant Sharma - YouTube

    Thanks in advance!

    in the Express.ypH you have provided there is 2 things and none of them is the cartoon character who is drawn on a video:

    • * the first is a 3D CGI that mimics the movements of dances from the dancing and I think that this has been done from observation. certainly NOT the Rotoscoping.
    • * the second example is a dancing man - a video cutting cutting - perhaps he was dancing in front of a greenscreen, we do not know but is not a caricature but a cutting of a video which has been applied some effects to make it more graphic but still, it's a video and I think that one who was cut by using matte procedure (picture effect) after the dancer was shot in front of a green screen. the face attached to the dancer is a follow-up on the face and securing its position and rotation of the information from tracking data so it will match. This is called the track or the movement of the game and it is a skill that requires time and patience to learn. but it is sometimes easier than rotoscoping. the two can be combined together to make life easier for the ROTO. but it's advanced things.

    On rotoscoping as an Art to cut out an Image of a video (not picture on it):

    There are several ways to make rotoscoping (cutting of the motion picture), and they all need a lot of practice and patience. There is no way to do it easily and it is a skill that takes time to penetrate. different types of techniques are described here: https://www.fxguide.com/featured/the-art-of-roto-2011/

    draw on top of a video (without cutting) is animated rotoscoping and can be done in Photoshop. some do it with "Chronology of Animation Frame" and others with "timeline of the video.

    The main workflow is the following:

    1. you import your video in photoshop

    2. create a timeline of this video

    3. do frame-by-frame on top of the video

    4. export the sequence as a new video

    more on the process of these Roto technical animation can be found in this post.

    Re: rotoscoping techniques: Animation video vs Timeline -there are links and information in the post of different examples. the post is a work in the making. I tried to treat it as an article, but new to the Forum (in terms of contributing content) carried out, once a user posts a comment on my comment - I can't access (which makes sense)

  • two elements that have the same source

    Hi guys,.

    I am trying to use the display on a Google Map plugin location. As I had this plugin requires two elements that have the same source:
