Despite being completely invisible to the viewer if done correctly, matchmoving is one of the most important parts of the film and television visual effects pipeline. Almost every TV programme or movie today has some form of CG element placed into real-world footage, so having a good working knowledge of a matchmoving software package can only be beneficial for your work and your CV.

MatchMover is Autodesk’s straightforward and cost-effective camera-tracking application. Here, I’ll show you how to create invisible effects with this software. First, load your file sequence: Locate your image sequence, and select the first image: I always like to manually track a scene for much more accurate results, but MatchMover comes with some pretty decent automatic settings, which, if you’re lucky, will give you a matchmove good enough not to need changes or tweaks.

Depending on how long your image sequence is, and the number augodesk tracks that are being created, an automatic track can take a couple of minutes. The longest part of the process is the solving for camera option, because this takes all the information from everything in the scene and creates a virtual camera that should mimic the movements of the matchmpver camera on the set.

Once this process is finished, you should have a scene with a fair number of green tracks, and maybe some yellow ones, following various points in your environment. The colours indicate the quality of the tracking, where green indicates good and yellow fair.

Red indicates bad tracking. Any red tracks should be deleted. Navigating in MatchMover’s 3D mode is not as easy or as fluid as other 3D software packages. To examine your 3D tracking, you have options to pan, dolly, orbit and roll.

When orbiting the camera, the 3D view automatically orbits around the selected 3D object, point cloud, or camera. As you navigate around your 3D scene, you should be able to recognise the different elements of your scene made up from the blue cones. Through this view you should see the blue cones stick to parts of your environment and follow the movement of the camera.

Once you’re happy that your automatic track has tutorila successful, you can go on to render and export the tracked image sequence and camera data to a file format you can open in your favoured 3D animation tutorizl compositing program. Some scenes are filmed with markers to provide a selection of places throughout the scene to add manual tracks.

Your cursor will change to a crosshair while in the workspace. As you hold down and click the desired area to add your track to, you can use the magnifier window to help precisely position the location of the new point.

Then release the mouse button to create the track point. This will create a window with a label, Track After the point-tracking process is complete, its trajectory line will appear in your scene.

Depending on how successful the placement of the track was, the line will either appear green, yellow or possibly red, or with segments of all three colours.

As with automatic tracking, you’re aiming for a full green line throughout the entire scene. However, if there are little segments of yellow, these can usually be left in without affecting the overall matchmove too much, as long as the track. You can correct yellow and red segments of a sliding track by manually adjusting the point positions where the track has drifted significantly, then re-running the tracking process.

How to create camera tracks with MatchMover | Creative Bloq

It only takes one bad track to completely throw off the accuracy of your scene. Go to a frame in which the track drifts, then click and hold the tracking point in the workspace and move it in the direction that will improve the tracking. Continue to use the magnifier window that appears around the point to help you adjust the point’s position. When you release the mouse button, MatchMover will clear the end of the trajectory, which will need to be tracked forwards or backwards once more for MatchMover to calculate a new trajectory for the track.

Name your file and select the format you require. The export options for Maya give you a default setting that exports your cameras, 3D points and the distortion grid, but these can be unticked if you don’t want them.

Since you haven’t selected what you want to export in your scene, you’ll need to change the Points option to All Tracks That Match. If you’re exporting a manual track, you’ll notice that you only have hard tracks to export, but options for hard and soft tracks can also remain ticked. You can export good, fair or bad tracks. If you’re exporting an automatic track, but you haven’t already deleted any red 2D tracks, untick this option.

Finally, you want the option of Animate to affect your camera and not your tugorial. Click Save and import into Maya to see your results, ready to add your CG elements.
