The following are some general principles to keep in mind. Keep this in mind if you are trying to mix and match live footage with digital elements. 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; }. Two images are displayed on a screen, one image emits horizontally polarized light only, and one emits vertically polarized light only. Set an expression on the X position of the left and right footage layers. for simple matching of perspective, there is the corner pin effect (and cc power pin)…. Anaglyph glasses are the oldest method, and by far the cheapest. 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. 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… Again, the 3D switch essentially adds a third dimension (Z-axis) to a layer. You can work with real footage and integrate 3D elements in After Effects. Trendy Perspective Transitions - Trendy Perspective Transitions contains a set of presets effects that you can use to swap between different media. Normally, cameras are spaced 6.5 cm apart to be similar to eye separation. If you are converging to the camera zoom, add the cameras zoom value to the z offset for the focus distance expression. After Effects does this effect when you select Converge Cameras in the Stereo 3D Controls. Take your motion graphics projects to the next dimension with 3D in After Effects. You can view all MAX content without signing in. It takes that value and modifies it as needed. Expression to set on the Focus Distance property: stereo_comp = comp("YourCompName Stereo 3D"); s3d_controls = stereo_comp.layer("Stereo 3D Controls").effect("Stereo 3D Controls"); converge_to = s3d_controls("Converge To"); convergence_z_offset = s3d_controls(8); converge_to_pos = (converge_to == 1); converge_to_poi = (converge_to == 2); converge_to_zoom = (converge_to == 3);if( converge_to_pos ) { convergence_z_offset; } else if (converge_to_poi) { convergence_z_offset + length(transform.position, transform.pointOfInterest); } else if ( converge_to_zoom ) { convergence_z_offset + cameraOption.zoom; }. When cameras converge, you change the perspective of the view, since the cameras are rotated and thus distortion is introduced. Logo 3D Animated Shape. Turn on the associated 3D mode on your 3D TV. If you wish to favorite sessions, you will need to sign in with your Adobe ID account. No need to use Photoshop, work directly in After Effects! In this comprehensive course you'll learn everything there is to know about working in 3D in After Effects and start adding depth to your compositions in no time. 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 create a light in your main composition, that light isn't used in your Left Eye and Right Eye composition and not in your Stereo 3D composition either. Objects that are aligned turn black. The glasses have polarized lens such that each only lets through light polarized in one direction. Start out by taking any composition that has some 3D layers positioned along the z axis. However, it possible you have to rework any keyframes if you change your output size. 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). If you have keyframed your Convergence Z Offset property, you can set an expression on your focus distance to match the convergence z offset. 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. Using toe-in can give more control, but there are several factors to be aware of when doing this. Add a Slider Control expression control effect to your Stereo 3D Comp composition and name it Footage Convergence. 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. Also take into account correct units as mentioned previously since After Effects operates in units of pixels, not centimeters. Remember to watch the video tutorial and see how Jeff, our Adobe certified instructor, creates this corner … Ones viewing experience can change depending on how big the screen is and how far away the viewer is from the screen. 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). As you can tell, there are many moving parts when working with stereoscopic 3D. Another important depth cue is lens blur. When working with converged cameras, it is very easy to match your focus distance and convergence planes. Matching it might be somewhat difficult. It's pretty simple to edit while previewing the stereoscopic 3D effects that you are changing. Ian Robinson is the creative director for SoftBox Media and a Master trainer specializing in motion graphics and visual effects. In Part 3, you’ll create eye-catching scenes. The workflow currently requires a little bit of manual work. In After Effects, it is much easier to change the convergence point of your stereoscopic 3D camera rig because you can change where the cameras are pointing quite easily. Increasing this value pushes the convergence point away from the camera, so all objects in the scene pop out toward you when you view it on a 3D monitor. This VFX lab will build the foundation of basic knowledge you need to start navigating and using After Effects effectively and efficiently. To preview this effect, change the 3D View property in the 3D Glasses effect to Difference. 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. Set an expression on the 3D Glasses effect's Scene Convergence property to automatically account for this. Option-click the stopwatch for each property in the light and using the pickwhip tool drag it to the associated light property in the main composition. After Effects creates a Left Eye composition and Right Eye composition driven by left and right cameras. It is very difficult to get different perspectives from an image that has already been recorded (though there is research happening in this area). 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. Switching to After Effects 3D. Changing the convergence plane with live footage is as simple as changing the horizontal alignment of the left and right images. Join Alan Demafiles for an in-depth discussion in this video, Use 3D layers for multiplane parallax, part of After Effects CC 2021: Character Animation Essential Training. When working with converged cameras, it is much easier to know how far away your convergence plane is. For the purpose of simplicity, here is the workflow using stereoscopic footage as a background plate. It's necessary to counteract the composition width percentage calculation. But there are some things you can do to make it better. Look through a windshield with water droplets on it at night. 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. After Effects gives you the ability to take advantage of 3D, and in the Ultimate Guide to 3D in After Effects I'm going to show you how! To create a 3D effect based on regular 2D images, the best choice is probably Volumax 6 for After Effects. To understand how much those objects will stick out in either direction relative to the plane, see the section on Stereo scene depth. Think of the convergence plane as an anchor point for the stereoscopic 3D space. Factors that can cause ghosting are hardware synchronization between glasses and monitor, battery power of glasses, dynamic range of the monitor, or refresh rate. 3D Perspective Text Logo Designer It's a free online 3D text editor that makes easy to design perspective letters and words to your 3D logo or banner. With options for softness, bend, length, color and many other properties, the Shadow effect goes far beyond the various shadow tools available inside After Effects. Paintings or games can appear 3D because they obey these rules. Changing your settings under Stereo 3D Controls should update the cameras in your initial scene. Any layer that is at the same distance as that plane from the camera is converged upon. LInkedIn Learning: https://www.linkedin.com/learning/instructors/ian-robinson.
