The search size should, for example, be increased if the camera moves quickly and the Track in the neighboring frame is too far away to be located. Again, a brief statement about how 2D Tracking works: The 2D pattern of definitive points in the footage are tracked (followed) over a long time. We’ll cover common problems and troubleshooting tactics for when you’re track isn’t cooperating. I have some footage that I have 3d Camera tracked in AE. During tracking, an attempt is made to locate the tiny image elements saved to keyframes in the following frame of footage within the range defined by the Default Search Size values. The newly created Tracks will not be selected by default. Get familiar with how to shoot, track, and composite. Why Tracks have to be fine-tuned is explained under What are good and bad Tracks?. This has to be corrected, of course. Sean Frangella did a great, 2 part in-depth tutorial on the workflow here. Hence, the color weighting can be used to define the color contrast for the Track very precisely. These are saved as keys and will then be searched for in the neighboring frames within the square associated with them (Default Search Size). Required fields are marked *. If the pixel region belonging to one Track ends, e.g., if it moves out of view, but the Track still jumps to a similar location, you have to trim the Track in the last frame, as described above. Regions with no contrast cannot be tracked. In this case, tracking in reverse wouldn’t make any sense. To clarify: If your perspective view is set to the size of the original footage and Resampling is set to 100%, both sizes will display the monitor’s actual pixel dimensions. Track your shot in After Effects, attach that track to null (since you cant export tracking data directly to lights) 2. Cinema 4D R20's Motion tracker makes it easy to track footage and let you add whatever you want into your video. If a Track was already tracked, it will be re-tracked (if the Auto Update Tracks mode is enabled) after being repositioned (including key generation). Learn how to use Redshift and C4D's Physical Renderer with R20's motion tracker to composite 3D renders onto your video footage. The Minimum Spacing value or an insufficient number of pixel regions found by the algorithm that are good for creating Tracks can, for example, result in fewer Tracks being created. The larger the value, the greater the tolerance. Learn how to use Redshift and C4D's Physical Renderer with R20's motion tracker to composite 3D renders onto your video footage. The 2D Tracking tab’s settings are used to define all Track properties used to track positions of distinctive regions in the footage. You can delete these tracks to avoid unnecessary confusion for the camera reconstruction. This value is also shown as an interactive slider in the Motion Tracker graph (for which the 2D Tracking Acceleration mode must be enabled). At left poor contrast, at right good contrast for the Track. Track paths that are only faulty starting at or up to a certain time in the animation do not have to be deleted completely. Virtual keyframes are colored light blue in the Motion Tracker graph. Very low Error Threshold values will result in Tracks remaining only on homogenous, monotone surfaces, which is no surprise since these types remain practically the same from one frame to the next. Cinema 4D R20’s Motion tracker makes it easy to track footage and let you add whatever you want into your video. If the Track is of no use at all, simply delete it entirely. Note that a reconstruction must be reconstructed after Tracks have been modified! Single-point Tracking. Footage provided by instructor. If this happens, adjust the filter settings accordingly. Those that go entirely astray, like the one at the bottom left in the image above, are faulty and should be deleted. Use these options to switch the pattern and search size representations for User Tracks on or off in the Viewport. The following options are available: Internally, the difference to the previous key (corresponding to the Tracking direction) will be ascertained for each Track at each frame. This filter waits until all other filters have been run and then filters the Tracks that are shorter than the defined length in frames. However, you will always have situations that will require you to manually set Tracks - often in addition to those that were created automatically. Selected Tracks can be deleted by pressing the Del key (to be exact, they will only be hidden and ignored during reconstruction; they can be recalled at any time using the Restore Deleted command). Select Tracker View if the a selected User Track’s footage should be displayed in consideration of the color channel weighting described below. Tracks that lie at a great distance from the camera (horizon, sky, etc.) Now bad Tracks/paths can be corrected or deleted (see also Working interactively with Tracks) before camera reconstruction is started. A brief description about the differences between Automatic Tracking and Manual Tracking: You can use Automatic Tracking and Manual Tracking individually or simultaneously. Once Tracks have been created, they can be modified interactively and individually at any time using the handles at the bottom right of the squares (if they were already tracked they will be re-tracked automatically after being modified). Scaling/moving the footage in the Viewport. The track is solid and runs around 150 frames long. If you take a look at the image above you will see that the pattern size encompasses the small horizontal line of the letter F. If the algorithm tries to locate this pattern in the next frame it can happen that it erroneously identifies the large horizontal line as the Track. Generally speaking, it makes sense to generate a high number of tracks but if these lie too closely together they will require an unnecessarily large amount of render time without offering noticeably better results for the camera reconstruction. HI. Selected user Tracks will normally be displayed using pattern and search size (the differently-sized squares). Tracks should also be present at those locations at which you want to insert 3D objects. You would then create the Track at frame 98 and track forwards from this point on. A Track can be assigned a unique name by double-clicking on it. a look at the Motion Tracker in Cinema 4d Here, Sam shows how you can track the footage, clean up the tracking data, and remove the errors that can impede a good track. Note also the Footage Display and Tracker Display options (see above), which can be used to see what a Track sees in conjunction with the defined color weighting. Generally speaking, Tracks that lie close together often have similar paths. Note that you can define negative values. Cinema 4D R20's Motion tracker makes it easy to track footage and let you add whatever you want into your video. The small square represents the pattern size: a tiny piece of bitmap saved to a given key. The regions are marked by the small squares in the image above. This doesn’t always work completely, which means you will have to delete these Tracks and their paths manually. If nothing is selected, all User This is done as follows within the temporal range defined in the Footage tab’s menu: Normally, it is recommended that the Manual Track button be used because it tracks in both directions (temporally). This option enables or disables virtual keyframes for selected Tracks. However, under other circumstances more Tracks can also be created (e.g., if a very low Number of Tracks value is entered). This setting can be used to change the color weighting of selected Tracks. If not, the Track must be adjusted frame-by-frame until the tracking is correct or the left key is no longer seen in the footage. The aim is to follow and save the 2D position change of a Track as long as possible in order to reconstruct the three-dimensional scenery in a subsequent step. Details about color weighting can be found under Preferences: Weighting Red/Green/Blue. With a little luck, the Motion Tracker will now follow this key. If you have footage that, for example, has a round marker (or small spheres), the Circle option should be selected. Tracks that jump to other positions or shift in relation to the underlying footage are also faulty. Learn how to use Redshift and . @redshift3d used for custom made shaders inside @maxonc4d rendered with #redshift3d experimenting with a wireframe cloak reveal too. The footage can be moved by pressing Alt+MMB and dragging. Since the camera movement and the graininess of the footage make it almost impossible to locate the exact pixel values, this threshold value can be used to allow for a certain deviation within which search patterns will be viewed as being identical. If this happens, keys can be added manually. The number of Tracks created and their dispersion can be controlled using the Number of Tracks and Minimum Spacing settings described above. These settings represent the pattern and search size of the Tracks and can be modified interactively in the Attribute Manager or in the Viewport. Folders can be created to organize the User Tracks. We'll cover common problems and troubleshooting tactics for when you're track isn't cooperating. Cross-shaped pixel regions are well-suited for tracking because they offer many, easily tracked corner points. The same applies to reflexions (a.k.a. The following properties are shown in the list for each Track. These can be modified by clicking/ double-clicking. Default Pattern and Search Size measure the scaled footage in pixels. Cinema 4D has the Motion Tracker, an easy to use tool for tracking footage. Track paths that are similar and lie parallel to neighboring paths are generally better paths. For example, red is perceived three times brighter than blue for a constant light. This setting defines the minimum distance (in pixels) that Tracks should have to neighboring Tracks (some Tracks might end up being placed closer together during 2D Tracking). However, it can sometimes be useful to track in only one direction, for example if you have a User Tracks whose pixel pattern doesn’t appear until frame 98. Copy paste your position data from that null to light object. 1. Now take a look at the red Tracks on the lamp at the right of the desk. A successful reconstruction of a 3D camera or an object depends for the most part on proper creation of Tracks.

These can be scaled individually using the handles at the bottom right corner (Tracks that were already tracked will be tracked again). Normally, a User Track is created by creating a key and tracking it. When working with a small number of manually created tracks, make sure that these do not start and end simultaneously. The total number of Tracks that are created can differ from this value. This can make it easier for the algorithm to identify Tracks for fast and smooth camera movements since the search region will most likely lie somewhat closer to the next assumed Track position. This will create the virtual point cloud in which the software will calculate the interpretation and relationships between each point, making it possible for a virtual camera location to be generated. Now let’s look at the green Tracks: you will see that these lie at clearly definable, high-contrast positions - such as corners - that remain constant in 3D space. Learn how to use Redshift and C4D's Physical Renderer with R20's motion tracker to composite 3D renders onto your video footage. Imagine you want to track a red marker on a white background. Around each User Track you will see 2 squares - one small, one large. Cinema 4D R20's Motion tracker makes it easy to track footage and let you add whatever you want into your video. lens reflexes), specular highlights, etc. These can be selected and deleted prior to starting reconstruction. These are, however, crossing points. A new Tracking will be created immediately. The right Track on the floor lamp was tracked perfectly by Cinema 4D but, as already mentioned above, this is a crossing point that changes according to the perpsective from which it is viewed and should therefore not be used. Tracks can be created automatically and/or manually at any point within the footage. I export my file with cinema 4d exporter and save the .c4d project. Here the Track with the color of the Color Filter selected below will be marked. Then he jumps to CINEMA 4D to model, texture, and light the product. are rarely useful because no useful parallaxes can be observed. If the Track is moved to a different time, it will again be placed on the bottom right corner of the area if the Shift key is used (at least if you move it to the general vicinity). Listed user tracks can also appear in the Object Tracker’s Tracker tab menu. If you want to track them, select the ones you want to track and click on the Auto Track button (or select the corresponding command from the context menu). Paths that are extremely shaky like the ones at the center are often faulty (but not always, e.g., if the camera’s movement is shaky, the paths will also be shaky; however, very shaky camera movements are generally quite rare). Here you can define the number of Tracks that the algorithm should create per frame. If Resampling is set to 50%, both search sizes will be twice as large as the monitor’s pixel dimensions. Tracks selected in the list can be deleted by pressing the Del/ Backspace key. If enough of these types of Tracks are present and cover a large area, the algorithm can create a correspondingly more precise camera reconstruction. The Tracks list contains a list of all User Tracks that were created (multiple selection possible) that correspond to Tracks selected in the Viewport. The, Move the footage in the Motion Tracker view, Move the Track directly in the view with the mouse. My next @skillshare course is on #motiontracking in #cinema4d. Furthermore, they also represent easily identifiable objects that can be tracked manually at other times in the footage, if necessary (if the algorithm fails to do so itself). However, this is not necessary if the quality is o.k. If this difference is greater than the threshold value defined here, a virtual keyframe will be created. This filter is similar to the Maximum Acceleration filter described above but it does not view each individual Track separately but in conjunction with neighboring Tracks. This name will also appear in the Attribute Manager for the 3D feature associated with it after the 3D reconstruction. This course is for beginners and advanced users alike. When a user track is created, the sizes defined in the Options tab will initially be used. We’ll cover common problems and troubleshooting tactics for when you’re track isn’t cooperating. This is exactly what these two settings define. Virtual keyframes help with tracking by automatically adding new keys to the tracked section according to the settings below (contrary to manually-created keyframes - which are permanent - these virtual keyframes are dependent on the virtual keyframe settings, among other things, and can therefore change). This means that the number of Tracks can be kept fairly constant. Get familiar with how to shoot, track, and composite. If the, Tracks that do not lie exclusively on a single plane are important (e.g., not all on the table top). These are not non-modifiable points in 3D space but are effects that change according to the perspective from which they are viewed. Here the pattern shape can be modified. .. In the image above, the Track was positioned on the left key and tracked. After these have been created, the superfluous Tracks can be deleted manually or via the Mask function. This course is for beginners and advanced users alike. Cons: Needs a clear contrast point to be … 3D Tracking , Matchmoving, Camera Tracking.... What does it all mean exactly ? Your email address will not be published. With the introduction of Cinema 4D R20, the direction to be tracked per key can be defined (even subsequently), i.e., the direction can change multiple times for a single Track - of course only if desired. This is one of the most important Motion Tracking functions. We'll cover common problems and troubleshooting tactics for when you're track isn't cooperating. Why not? Clicking on this button will create a series of Tracks that are dispersed as evenly as possible, including a keyframe at the current point in the animation. Otherwise you will have to do some fine-tuning by adding Tracks manually or by deleting bad Tracks that were created automatically (see also What are good and bad Tracks?). Fewer but good Tracks offer better results. When I open the .c4d file in cinema and play it back it will play fine. Learn how to use Redshift and C4D's Physical Renderer with R20's motion tracker to composite 3D renders onto your video footage. The Track will then be continued (you may have to trim again right before this key if a faulty path was tracked). Get familiar with how to shoot, track, and composite. The default filters and their values are already optimized for best results. If the pattern size lies exactly on the circular shape, it doesn’t matter if the background changes (which would on the other hand be the case with a square pattern size, meaning that the pattern might not be found). Their Track paths only have to be trimmed starting at or to the faulty point. However, it can happen that the virutual keyframes can shift from their original, manually defined footage position. Animate 3D objects with tracked footage Search Add animated 3D objects to tracked footage in Adobe After Effects and use the Fracture object and plain effector to easily animate text using Maxon Cinema 4D Lite, included with After Effects. This can be slightly irritating because the search and pattern sizes will be displayed with different sizes, depending on the Resampling value defined. The footage will then be shown as a grayscale: Tracks can be best followed in regions with large contrast, e.g., black-to-white transitions (see next image). Creating a Background Object in Cinema 4D is a great way of making sure that the footage is tracking correctly in Cinema 4D To get the 3D camera and solid data into Cinema 4D, go to the After Effects File>Export>Maxon Cinema 4D Exporter. These three buttons are used to track the User Tracks. Singled out examples of bad Track paths (the filtering was purposely reduced for this example). Tracks whose position jumps wildly from frame to frame have a greater velocity and are often (but not always - see below) faulty. Generally speaking, the best Tracks are those that can be precisely followed (tracked) over a long period of time and also represent a definite position in 3D space. As you can see, the Track starts to shift at frame 2 and finally comes to rest over the center key. Therefore, it doesn’t make sense to create thousands of tightly clustered Tracks. 3. Cinema 4D R20’s Motion tracker makes it easy to track footage and let you add whatever you want into your video. After reconstruction, manually created Tracks will be displayed as separate Null objects in the Object Manager. New Tracking will be created for the selected Tracks (see also ). However, it can sometimes be useful to track in only one direction, for example if you have created Tracks at frame 76 because the pattern on which they are based doesn’t appear until this point. Enabled=circular; disabled=quadratic. Use these three buttons to track the selected Auto Tracks (or it will create some, if none have been created, yet). Imagine the camera moving to the right: these points do not define a definite point of reference in 3D space - they change according to the perspective and are therefore useless. We’ll cover common problems and troubleshooting tactics for when you’re track isn’t cooperating. On the other hand, and depending on the footage, the filters can be too aggressive and filter out too many Tracks so that barely any are left. Your email address will not be published. If this option is enabled, the region encompassed by the Default Search Size will be moved slightly forward to its expected position in accordance with the Track’s (past) direction of movement. The smaller the value, the less modification that will be allowed compared to the previous frame and the more virtual keyframes will be created and vice-versa. Here you can switch between Square and Round User Tracks. Among other things, this will help you position the objects more precisely. Info: Disable this option to make the Track modifiable again. Tracks are small regions of footage that can be found again in the previous or following frames of the footage. After 2D tracking has been completed, each Track’s path through the animation will be displayed. Just playing around with some #c4d motion tracking. Using The Foundry Camera Tracker, you will track and solve some footage, resulting in an After Effects camera and reference nulls being created. In the Color Filter selection menu you can select from the following options: Default Pattern Size [3..10001] Default Search Size [5..10001]. Try using Automatic Tracking first and if a good camera re-construction is produced, fine. Learn practical tips and tricks for the entire process for motion tracking with Cinema 4D and After Effects. Color Filter Filter.Red [-200..200%] Filter.Green [-200..200%] Filter.Blue [-200..200%]. Cinema 4D’s Object Tracker can quickly rebuild the motion of the camera along with any number of objects in the scene, bridging the 2D and 3D worlds. Get familiar with how to shoot, track, and composite. If an Auto Track subsequently disappears it means that it was filtered (see Filter). These can be made visible by setting, If strong motion blur is used, it may be necessary to increase the, Tracks on objects that are obscured temporarily in the footage can be continued when they reappear (if the Track is selected prior to the object being obscured, right-click on the position and select, Right-click on the desired position in the Viewport and select. See more ideas about motion, cinema 4d, cinema 4d tutorial. This is useful, for example, if you want to create Tracks at specific location. Learn how to use Redshift and C4D's Physical Renderer with R20's motion tracker to composite 3D renders onto your video footage. Use a Track ONLY for a single pixel pattern (the Track can, of course, use multiple keys for a specific range of footage)! Details for both sizes can be found here. After this course, you’ll be able to go film, track and render out a composited shot with your own footage. Use as many as possible that also overlap temporally. Why not 100%, 0%, 0%? Get familiar with how to shoot, track, and composite. The solution in this case: simply drag the Track back over the left key in frame 2. In previous versions of Cinema 4D, only the combined brightness of all 3 color channels was taken into consideration. Enable this option if you are happy with a User Track and want to protect it from being accidentally modified (moved, deleted, etc.). The assignment is made according to the Object Tracker’s list of Tracks (Tracker tab). In particular if most other Tracks’ paths are more harmonious, like the ones on the keyboard in our example.
