How To Use A Camera In After Effects

How to Use 3D Camera Tracker in Later Furnishings on Mac

Jun 17, 2022• Proven solutions

Whether you are an aspiring director or a habitation movie maker, Adobe Afterward Effects's camera tracking is 1 of the exceptional functions. The 3D camera tracking in Later on Furnishings on Mac helps track objects within a specified video prune to add various 3D elements. The ideal use of motion tracking can finer transform live-footage into the stuff of engaging high-tech footage. Without farther ado, let'south understand the tracking camera in After Effects in detail as follows.

Role 1: What'southward 3D Camera Tracking?

You can perform 3D camera tracking in After Effects with its inbuilt 3D Camera tracker. In full general terms, the lucifer-moving or motion tracking describes alive-action cameras' simulation process and their related perspectives via After Effects or similar software. The 3D motility tracking is typical of special effects on different feature films and commercials, including character animation. The 3D camera tracking in Afterwards Effects is to simulate the intricate moves of a live-footage photographic camera across all three axes.

The 3D camera tracker's effect helps analyze unlike sequences of video to extract 3D scene data and camera motion. It further allows us to blended the 3D elements over 2nd elements correctly.

The side by side section volition cover the After Effects photographic camera tracking tutorial in terms of a 3D camera tracker.

Office 2: How to Use the 3D Camera Tracker in After Effects on Mac?

Given below is a full-fledge Adobe Subsequently Effects photographic camera tracking tutorial with the assistance of 3D Photographic camera Tracker.

Step ane: Launch After Furnishings on Mac

Download Later on Furnishings on Mac and fix the projection. So select Composition > New Composition. Gear up the width as 1280 and tiptop as 720 in the Composition Settings window. Ready the Duration to 12 seconds and Frame Rate to 25 to ostend with the OK push button.

Step 2: Import Media File

Select the paradigm sequence and go to File > Import > File. Turn on the JPEG sequence option in the Import File window and striking the OK push.

Afterward selecting the paradigm sequence in the Projection window, open the Interpret Footage window and set the frame charge per unit to 25 to confirm.

Then, elevate and drop the paradigm sequence in the limerick bar every bit shown beneath.

Step three: Open Track Camera

Select Animation > Track Camera.

Step 4: Analyze the Footage

After you open the tracking camera, it starts analyzing the background footage in two steps.

Step 5: Add together 3D Camera Tracking in Afterward Effects

After the analysis process ends, increase the value of Track Point Size in the 3D camera tracker issue.

Step vi: Select Track Points

Now, you are required to select unlike track points to generate a dummy 3D plane/aught. Please select at least 4 of them, as shown in the image beneath.

Step 7: Get the Naught Object

Correct-click the selected points and hit the Create Zilch and Camera button.

Now, you have the nil object and 3D camera in the timeline. The null object acts every bit a placeholder to stick with the footage and follow the camera.

Pace 8: Export 3D Camera Tracker Data

Y'all can consign this 3D Photographic camera Tracker data to various applications equally follows.

• Select File > Consign > Maxon Cinema 4D Exporter.
• Select among the Extrude or Text pick in the Text Exporting dialog box.

• Once you proper name and relieve the file, open it in a 3D application.

Part three: Common 3D Photographic camera Tracker Problems in After Effects

Later agreement how to track camera After Effects, information technology'south time to discuss their standard troubleshooting, which you faced or may face up in the time to come while operating the software. And then it's better to deal with them now!

• Fix the 3D Camera Tracker

If you get to come across the error as "3D Camera Tracker: Layer size must match the composition and use default transform", fix information technology at present as follows.

Y'all are first required to note the size of the image sequence or video clip. Then, select the prune and right-click Pre-Etch. Use the Settings provided in the Pre-Compose window. Hit the OK push to confirm.

At present, go to Composition > Composition Settings and ready the size to the same as you lot noted earlier. Click and drib-downwards and select Reset under Transform if yous take already set it to the Fit to Composition.

So select the prune > Effect Controls > 3D Photographic camera Tracker to make it work once again.

• Ready the Analysis Solve Failed Mistake

It occurs when Adobe After Effects camera tracking fails. Sometimes yous also get to detect Background Changes and Multiple Camera Angle in the video sequence.

So, what practice you lot need to resolve the issue? You demand to trim the video with a change in Camera Angle, Video Frame, or Background.

You tin can trim video till the beginning change. Then, play the video and check if you see only ane camera angle and no change in the background.

Go to Furnishings Control > 3D Photographic camera Tracker and delete the previously added effect to the clip.

Then move to the right and under the Tracker menu, click on the Camera Tracker.

The outcome will resolve now, and you will start to clarify the video for 3D tracking points. You can hover over the tracked points as well.

• No Depth from a Tripod Pan Solve

The error "no depth from a tripod pan solve" will bear witness at the target icon'due south bottom. It happens fifty-fifty if the track points are at equal distance from the photographic camera and of the same size.

Well, it's not a situation to freak out! Information technology's all done due to the absence of the parallax consequence. This effect commonly comes to notice when static objects seem to be moving at different speeds from different distances. Similarly, the 3D Photographic camera tracker uses this outcome to figure out an object'south reach from one some other.

The panning movement occurs when the camera doesn't motion across the scene very much. It's the reason the 3D tracker says that it can't derive in-depth data due to the absence of parallax effects in the shot.

Instead of freaking out, you can either use a 2D motion tracker or attach objects to "flat" track points. It will link other layers to the movement of the photographic camera, and the upshot will resolve.

Conclusion

And then, this is all nearly 3D camera tracking in After Effects on Mac. We discussed the ultimate tutorial with regards to using the 3D photographic camera tracker and post-obit the right path. Also, in that location are mutual troubleshooting issues with the solutions discussed in the last section.
