When tracking there are two (main things) that you need to be concerned with in tracking. While there are many variables that need to be taken into account, when shooting there are two things that you should keep in mind. First off, contrast, 99% of all tracking software uses contrast in the luminance channel (brightness) to determine a point and where it ...

I assume these are home made motion markers in order to track the motion of the head in the shot. This is useful for adding other objects (or images) to the object, therefore the technique is called object tracking. Note: The example given is only useful for 2d tracking, because most 3d solvers needs a minumium of 8 tracking markers around the object (in ...

I come from a Hollywood visual effects background, and I was a matchmove lead for a couple of shows. For the above process mentioned, Vfx facilities do it all the time. Like Poor mentioned, it is very labour, skill and time intensive. Unfortunately, in almost all cases if you see the actor in the shot without a tracking suit, and if we need to track / ...

What Kim Burgaard said is very true. The vocalist has a lot of control over how their voice is recorded. As I'm a much inferior vocalist to those I record, it can be difficult teaching them this technique, as you just want to get a good take. So what I end up doing is have the vocalist scream. Well, I ask them to warm up and hit the loudest levels they can. ...

Davinci Resolve lite is free, and it contains an excellent motion tracker. By combining the motion tracker with a power window, and adding a color correction (to darken everything outside of the power window), you should be able to achieve the results you're after very quickly. For tutorials on Davinci Resolve, search youtube for Alexis Van Hurkman. He ...

Unfortunately, this requires motion tracking and there isn't much out there that can handle it for free. (As Jason Conrad pointed out, DaVinci Resolve Lite can.) Motion tracking is pretty elaborate because it has to use complex computer vision systems to identify objects within the image and track where they move from frame to frame. After Effects is ...

And as there's always at least two ways to do things in After Effects, another option to Professor Sparkles' one is to parent the layers to the one you're zooming in on. Parenting a layer means that it is connected to its child layers such that any transformation you apply to the parent affects the child (but transformations to the child do not affect the ...

Thats simple, pre-comp what you have right now and create a camera layer. Then make you composition layer 3D. The look of you layer will not change unless you add lights or rotate the camera. Then you can pan around and zoom in your picture with the camera. Thats how you do every sort of zooming e.g. camera animation in after effects. Animating the scale of ...

Select your camera, locators (if exported), and anything else from Nuke. Group them all together with ctrl+g and modify that group as a whole. You can scale uniformly (but not independent axes), rotate, and translate. Often one trick is to snap the pivot point of the group to a specific reference point (hold down d and v then drag to the reference point, ...

In After Effects CC, masks can be made into tracking masks. Right click the mask and you should see a context menu with Tracking Mask. Select it and the mask can be tracked to the video it is applied to. The Adobe page about it is here. This will track the video but the mask will be a rigid shape. If you want the points inside the mask to track individual ...

Here's one way to do it. I'll assume you have basic motion tracking knowledge already for the sake of brevity. AfterEffects Turn on 3D space for your footage layer. Track the player in your footage. I'm going to guess that you'll have to do a lot of this by hand, but there's not really a faster way to track a player like this. Apply the track to a Null, ...

I would suggest as a starting point to use Corner Pin Tracking, found on the tracking panel of AE. Track each side of the sunglasses separately and when done, you should have two solids that move with the area of the glasses. Add a mask to each one, and rotoscope the actual shape of the glasses. I think this would be easier than rotoscoping from scratch. ...

A few things to try: Make sure your camera footage is at the same frames per second as your comp. Instead of selecting a single track point, try drawing a lassoo around several points. You'll get a target plane instead. Make sure it's facing the right way (if it's not - redraw your lassoo around some different points). Open the Advanced triangle in the ...

High-end sports productions have cameras that can pan, tilt, and zoom their way to tracking a golf ball when driven 300+ yards off a tee. Such systems are well beyond the budgets of typical user groups. A system called SoloShot costs less than $1000, and might have the spatial resolution needed for your application. Recording in 4K gives you a 2:1 punch-...

I take it you are looking for Motion Tracking. Unfortunately, Premiere Pro doesn't have that capability. You'd have to set keyframes for the animation manually, which can be a pain if it needs to be accurate. If you need to do automated Motion Tracking, you could switch to After Effects which comes with that capability (see link above).

You could do it in real life by attaching a transmitter to the ball and having a robotic pan/tilt tripod head track the movement. If you're shooting 4K, your budget's probably in line with something like soloshot. Or, of course, you could pay a cam-op. Taking the time (or paying someone) to track it in Mocha or AE will end up being more expensive than ...

With these kinds of things, I suggest not even using a green screen in the first place, especially one that is in an app and casts a green glow on the actors hands or body and picks up on reflections. Its much easier to have, instead, either a green piece of paper (which honestly will not really work in daylight in terms of the key but will at least give you ...

Trackers never hurt and there's almost no reason not to use them, but there's no substitute for pre-production and field testing. The only failure is failure to plan. Ideally your markers would be high contrast, however you can place darker green markers on a green screen which can be entirely keyed out if the artist doesn't need them, but will still be ...

Select the motion keyframes & copy. Now create a new mask on the layer on which you have the stroke effect, any old mask shape will do. Set its mode to none. Now select the mask's Mask Path property and paste. The mask can now be used to provide the path for the stroke effect (it's the first property in the stroke effect). You have to directly select the ...

Not sure how to do this with the stroke effect. But you can use a particle generator set the movement and physics to 0 and link the particle source to the trackpoint. This will generate a stroke of particles, and if you ramp up the amount of particles you can make a solid line.

I agree with the two previous answers: You'll need paid motion-tracking software such as After Effects. I wanted to add that in addition to tracking the X-Y position in the frame, you will most likely need to track the "rotation" of the 2 eyes as well. That is, a horizontal rectangular mask will work for the eyes of a person facing forward with his/her ...

You can use Lightworks (multi-plattform) for that or alternatively iMovie. Both offer either masking and or cropping. One of the most basic features in a video editor. Just watch one of the dozens of beginner tutorials for the tool that fits you the most. When you go with the cropping approach you just duplicate the video layer and crop each layer down to ...

Sounds like you need to track the camera in 3D. If you're using CS6 then the best thing for tracking the camera in 3D is the 3D camera tracker (who'da thunk it). To fire it up Choose Animation > Track Camera, or choose Track Camera from the layer context menu, or choose Effect > Perspective > 3D Camera Tracker, or (because there's always 3 ways to ...

I found a tutorial which uses Mocha for After Effects to accomplish my task exactly. Here is the link to the tutorial: http://www.imagineersystems.com/videos/mocha-ae-paste-mocha-shapes-to-after-effects-mask-channel/view

Singing with an microphone, both live and recorded, can be improved with a little technique. Compression cannot compensate for clipping and, as you point out, some singers have an incredible dynamic range. If you look closely at vocalists who regularly perform with microphones, you will notice they either move the microphone or the head to increase the ...
