If the two images overlaid look drastically different, this could cause strain. It also creates an output composition that puts the two views together into a format that is recognized by some stereo viewing method. If you align the left and right images so a specific object in your footage appears in the exact same location when overlapped. This technique is useful if you need to match live footage and add digital elements to that scene. Your convergence point is now located at the depth that matches how far that object was from the camera when you shot your footage (or however far that object is from your virtual cameras). VFX in After Effects CC: An In-depth Guide to Perspective and Generate Visual Effects in Adobe After Effects CC Rating: 4.6 out of 5 4.6 (165 ratings) 7,278 students When our eyes converge on an object, if there is a difference in horizontal position of that object between the left eye’s image and the right, our mind puts the object together into one and our brain thinks the object is a certain distance away (due to parallax). This separation between eyes that provides different perspectives is the key to stereopsis. It takes that value and modifies it as needed. In difference mode, look at the horizontal spacing of the left and right eyes between the closest and farthest object and make sure this is not too extreme. It's necessary to do some sort of calculation to compensate for the dimensions of the footage. It is very difficult to get different perspectives from an image that has already been recorded (though there is research happening in this area). This is the basis of how stereopsis works. Make sure that your depth cues are not giving contradictory information. If you want your focus distance to simply follow your point of interest, use the new command by right-clicking the camera layer in the timeline. LInkedIn Learning: https://www.linkedin.com/learning/instructors/ian-robinson. Otherwise, you can get different shadows or colors in each eye, which can be a cause of visual discomfort. In this session, you’ll learn about the latest tools and techniques to transform your 2D designs into 3D animations as we explore these topics: Audience: Game Developer, Motion Graphics/Visual Effects Artist, Post-Production Professional. With your Stereo 3D composition selected, click the controls layer and lock the Effect Controls panel so it isn't hidden. Avoid introducing an extreme amount of parallax. nor does it actually support 3D objects natively, so this could easily turn into some super complicated proeject where you need to connect and constrain everything with expressions, use elaborate sub-comps with expression linked cameras to "sync" movements and whatnot. Different colored lenses color filter each eye’s view differently. Import your stereoscopic left-eye and right-eye footage items. Red-blue glasses filter out blue on the left eye and red on the right eye. cameraOffset = effect("Stereo 3D Controls")("Stereo SceneDepth"); s3d_controls = stereo_comp.layer("Stereo 3D Controls").effect("Stereo 3D Controls"); converge_to = s3d_controls("Converge To"); convergence_z_offset + length(transform.position, transform.pointOfInterest); The left layer adds the slider value converted into percentage of composition width, and the right layer subtracts it. Setting it back to 0 gets rid of all stereoscopy, and everything is on the plane of the screen. Make sure to lock this viewer. Now you can drag your footage convergence slider to change the convergence plane of your stereoscopic 3D footage, and use the Stereo 3D Controls effect to control the convergence of your 3D elements. For this reason, the Stereo Scene Depth property is measured in % of composition width. Ghosting can happen from things that are out of your control. Stereo Scene Depth (interaxial separation) expression to match Maya cameras: If your cameras are in the wrong location, make sure to verify where the master camera from Maya is in relationship to the left and right. Adobe recommends that if you need to add lights, connect the lights in the left and right compositions via expressions to their counterparts in the master composition. The left eye is presented a view of a scene from some virtual or real camera that shows the left perspective. Once your scene is complete, you can begin to tweak the stereoscopic 3D controls for your scene. Because of the inherent color distortion, it is difficult to see all the colors accurately using anaglyph. It is very difficult and unnatural in real life, so this control—if used improperly—can have very painful results since our eyes and brain are not used to converging much more than allowed by the distance between our eyes. Open up two timelines to simultaneously show your main and either left or right composition. If you select Swap Left-Right in the 3D Glasses effect, it reverses all the convergences. for simple matching of perspective, there is the corner pin effect (and cc power pin)…. Open a new composition viewer, and set one to view your initial scene composition, and one to view your final stereoscopic 3D composition. Post questions and get answers from experts. If there is no blur, our brain thinks that the two are at a similar distance. If you switch to the 3D view and put on your glasses, objects on this convergence plane appear to be on the plane of the TV screen. Changing the Stereo Scene Depth value has the result of making the stereoscopic 3D scene appear to pop out or sink in to the screen more. Usually, it is easiest to have the left and right cameras converge to your master camera's point of interest (default). But most likely it is a display synchronization issue or similar problem with the 3D TV or display device. All of our After Effects Templates are free to download and ready to use in your next video project, under the Mixkit License. Increasing this control spreads the cameras out. If you see any part of the image that only the right eye should be able to see, you know you have a problem. It is usually unnoticed to the average person. If the close object is in the same general direction as the far away object, the close object switches sides of the far away object. 3D Glasses effect Scene Convergence property expression, try {                cameraOffset = effect("Stereo 3D Controls")("Stereo SceneDepth");                if( effect("Stereo 3D Controls")("Converge Cameras") == false ) {                                     value - cameraOffset;                } else {                                     value;                } } catch (e) {                value; }. In short, the concept is simple: create a left camera view and a right camera view of some 3D scene, and render them out. For the purpose of simplicity, here is the workflow using stereoscopic footage as a background plate. When cameras converge, you change the perspective of the view, since the cameras are rotated and thus distortion is introduced. One can clearly see this phenomenon as our eyes focus on different objects and our retinas blur the out-of-focus objects in the background. However, the camera and objects can have their own agendas in some instances, but a few tricks can change a seemingly uncontrollable camera animation into pure, cool cinematography… If you look through only one eye, you lose your stereopsis depth cue. A good thing to remember is that normally our eyes are about 6 to 6.5 cm apart. 1. However, don't this when using converged cameras. Start out by taking any composition that has some 3D layers positioned along the z axis. Stereopsis, being the most powerful depth cue, is no exception. Make sure that your Magnification Ratio in the viewer is set to 100%. This effect is strange, but experiencing it helps to understand how important these depth cues are and how important it is to make sure that they are all in alignment and agree. Here are a few methods. Objects that are aligned turn black. When you capture live stereoscopic video, you almost never want your camera rig to have a toe-in. The reverse could be the case if for example you are trying to put a stereoscopic video (like a TV screen replacement) into a virtual stereoscopic scene and the convergence of the scene needs to be different than the convergence of the footage. But depending on the camera size, it can vary (especially if the body of the camera is wider and it is not possible to place the cameras that close together). However, it possible you have to rework any keyframes if you change your output size. Make sure to replace. A wide-angle lens gives you more perspective depth cue information than a telephoto lens, for example. You can test this phenomenon by closing your right eye. Lights do not transfer into the precompositions with collapsed transformations. I had never tried the 3D Camera Tracker in my life. To have the best composite possible (and least painful), make sure to match the convergence plane of your 3D elements with that of your stereo footage. Therefore, there is much more opportunity for them to not be aligned, providing contradictory depth cues and causing eyestrain or brain pain. Home / Articles / Adobe After Effects / Building 3D Objects in Adobe After Effects CS5 . Here is a parody of the topic that shows a very unconventional method used by Jonathan Post: http://www.jonathanpost.com/. Great! All of the controls necessary for stereoscopic 3D are in two effects on this layer. Check your camera zoom; wide-angle lenses cause more distortion if your cameras are converging (. In this case, you can easily contradict your occlusion and stereoscopic 3D depth cues to give an interesting illusion. You should not see the black areas move back and forth—only the separation of the objects in front or behind them. Think of the convergence plane as an anchor point for the stereoscopic 3D space. At this point, you can go back to your starting composition and modify your camera position, depth of field, placement of layers, or anything else about the scene. Also make sure that the Units property in the 3D Glasses effect is set to % Of Source to match the units of Stereo Scene Depth in the Stereo 3D Controls effect; otherwise, an additional calculation is necessary. To understand how much those objects will stick out in either direction relative to the plane, see the section on Stereo scene depth. 3D glasses change the convergence of both together. In general, use your stereo footage as a background plate, and then composite your 3D elements on top of it. Normally, cameras are spaced 6.5 cm apart to be similar to eye separation. Objects that are converged upon appear to reside on the surface of the screen that is being viewed. Perspective Surface Logo 26130557 Videohive - Free Download After Effects TemplatesAfter Effects Version CC++ | No Plugin | 1920x1080 | 146 MBFEATURES:Customize Control LayerDrag and … In real life, one can mess around with our surroundings in intelligent ways to create optical illusions. Conceptually it makes sense; each object in the left and right image has a different horizontal offset depending on their depth due to parallax. After Effects creates a Left Eye composition and Right Eye composition driven by left and right cameras. When editing with stereoscopic 3D, it is usually invaluable to be able to see what exactly is happening and how the parameters you are changing affects your stereoscopic 3D rig. Change the 3D View property in the 3D Glasses effect to match one that your 3D TV supports: either Stereo Pair (Side By Side), Over Under, or Interlaced Upper L Lower R. Create a new composition viewer for your stereoscopic 3D scene, and drag it out of the After Effects frame onto the 3D TV. Just as you can create other 3D objects in After Effects, you can create 3D text. Working in broadcast for over 20 years with such clients as Discovery Channel, National Geographic International and PBS, he’s seen the definition of broadcast evolve first hand. Usually, you want your focus to match the convergence plane of the cameras. Feel free to add in any custom text or descriptions onto your card, as well. Remember to watch the video tutorial and see how Jeff, our Adobe certified instructor, creates this corner … Also, stereopsis can be added to any 3D composition in After Effects. No need to use Photoshop, work directly in After Effects! Everything farther away from the camera than that object appears to be pushed deeper in the screen. If you happen to have a 3D TV accessible, follow these steps to see your composition and edit in stereoscopic 3D live. Polarized glasses work on a simple principle. Make sure to lock those views so that they do not switch. Our brain interprets this as a depth cue without us realizing it. Make sure that your composition dimensions exactly match the resolution of the 3D TV. This is actually what 360 videos look like before being implemented in a compatible player. Remember that it is the relationship between the objects in the scene that matters; compare the horizontal separation of the closest object to the farthest. As first discussed, you have access to so many more variables than in real life. AFTER EFFECTS - AE_Project_0323 This cool presentation uses 3D perspective to show your footage. Make sure that your convergence point is somewhere predictable and not far off in the distance or very close to the camera where your eyes would go cross-eyed. Therefore, there is a high likeliness to introduce confusing depth cues that are contradictory and cause pain when viewing. Just define the input Perspective area with 4 Selection points, then the output Perspective area with 4 … Home and Away. If your eyes cannot converge or it is painful to see the image you might try these solutions: Move farther away from the viewing screen when looking through your 3D glasses. But more often than not, inconsistencies in the digital realm are considered unnatural and can even cause eyestrain or brain pain. I was able to make some basic perspective typography. Again, the 3D switch essentially adds a third dimension (Z-axis) to a layer. It's pretty simple to edit while previewing the stereoscopic 3D effects that you are changing. A cool way to enhance the look and feel of your TV shows, commercials, trailers, teasers, corporate presentations, business slideshows, promotions, and events videos. If two objects are roughly the same size in our field of view, and one is occluded by or is occluding another object, our brain infers that one of those objects is in front of the other. Finally, arguably the most powerful depth cue is stereopsis. Anaglyph glasses are the oldest method, and by far the cheapest. That way, if you change the size of your stereo composition, the stereoscopic calculation remains unchanged relative to the new size. Also take into account correct units as mentioned previously since After Effects operates in units of pixels, not centimeters. With parallel cameras, you can still see your focus distance or point of interest and you can see how this lines up with the perceived convergence point in your final output using the difference mode technique as described earlier. Now, if you switch to your stereo 3D view, you should see your 3D elements composited with your stereoscopic 3D footage. Matching it might be somewhat difficult. Objects in perspective, occlusion, and relative size are good indicators of depth. They use a stylish combination of effects to reveal your media. Especially with the new and improved Camera Lens Blur effect and related features in After Effects CS5.5. Likewise, you can tie the convergence point to the zoom to automatically keep the convergence the same while doing a perspective shift (changing the field of view of the camera while doing a dolly in). The course shows you how to select the right images and resolutions, how to use masks and layers to build the composition in Photoshop, and how to animate the camera and light the scene in After Effects. But depending on the camera size, it can vary (especially if the body of the camera is wider and it is not possible to place the cameras that close together). No further changes are required in your main composition. To preview this effect, change the 3D View property in the 3D Glasses effect to Difference. When two objects appear in the same location horizontally in both the left and right frame, the objects' distance from the camera indicates the plane of convergence. Sometimes it happens when there are sharp contrasts of color and the glasses are not able to entirely block out that image from the incorrect eye. Take your motion graphics projects to the next dimension with 3D in After Effects. From the course: Motion Control 3D: Bringing Photos to Life in Three Dimensions with After Effects and Photoshop CC Start my 1-month free trial Buy this course ($34.99 * ) To get any sort of realistic scene, you usually want to add depth of field, though usually it is subtle unless you are using a telephoto or macro lens. AE doesn't have interactive 3D grids and magnetic snapping of that sort. Stereoscopy is a digital technique for allowing our brain to see stereopsis by tricking it. Some TVs use no glasses at all, such as those from Alioscopy. If you import cameras (or nulls) from Maya and they are not lining up with the stereo rig camera positions, try adding the following expression to the interaxial separation (Stereo Scene Depth property) to handle the conversion to After Effects units. With parallel cameras, it is more difficult, and a little bit of eyeballing is required (See the section on ETLAT and previewing convergence plane with parallel cameras for more information). However if you bob your head from side to side with that eye still closed, you can get a sense of depth again. Look through a windshield with water droplets on it at night. But it is useful to change it to camera position (plus, for example, the focus distance as an offset) when trying to match convergence point and depth of field. No longer do the perspectives of the left and right cameras line up exactly. Our brain already knows how big those objects should be in relationship to one another. This problem is usually an issue with the way the display is showing your content. When dealing with parallel cameras, it is difficult to tell how deep in the scene the convergence plane is. Changing the camera field of view changes the perspective of the scene. Keep this in mind if you are trying to mix and match live footage with digital elements. Set an expression on the Convergence Z Offset property to match the focus distance of the camera. Expression to set on the left-eye footage layer's X Position property: Expression to set on the right-eye footage layer's X Position property: You can’t change the stereoscopic scene depth of footage after you've shot it. If you are converging to the camera zoom, add the cameras zoom value to the z offset for the focus distance expression. Optical illusions like the Ames Room, the Infinite Staircase, or tilt-shift photography are all examples of how depth cues can be manipulated and our brains tricked. Background layer is cut out and the composition in Stereo are about 6 to 6.5 cm apart they are with. This same exercise on an object that is touched by the depth field.
