![]() In our example, we used a Polar Facility map, which is available on the Epic Games Marketplace. Now let’s learn how to use the tracking data in Unreal Engine 4, which is also free. How to use your CamTrackAR data in Unreal Engine 4 Then come up to Render and select Render Animation. When you are happy with your scene, pick the folder it’ll be exported to in this case, it’s exported as a PNG sequence. This means that our 3D render needs to match the height of 1440 plus have extra on the sides to maintain the 16:9 aspect ratio. We changed the resolution to 2560 by 1440 as CamTrackAR records at 1920 by 1440. Lastly, change the Depth to Front to have the video in front of your 3D scene.īefore you export your background, check the Output Properties and make sure everything is correct, including the frame rate. ![]() Select Add Image, change the Background Source to Movie Clip, then open the video file. To do that, go to the Object Data Properties tab and checkmark Background Images. One thing that might be useful is to be able to see your video footage. This will move the camera but maintain the tracking data. It’s unlikely that the camera is positioned correctly You can fix this by adjusting the Delta Transform in the settings on the right. Lastly, select the layer and hit 0 on your keyboard to view the scene from your Camera’s perspective – now, your virtual camera should match the camera’s movements when filming on set. Next, find the take you want and select the. To import the CamTrackAR data go to File > Import > HitFilm AR Tracking Data. Our scene was made using assets from Video Copilot’s Star Pack and Sketchfab for the mountain. Lastly, ensure that “ Enabled Add-ons Only” is ticked.Select Install, then navigate to the CamTrackAR folder.First, navigate to Edit > Preferences > Add-Ons.In order to use CamTrackAR data in Blender for the first time, you’ll need to install a plugin – this only has to be done once: That good solution may bear no relationship to the real world that the data derived from.How to use your CamTrackAR data in Blender Having a low solve error just means the solution found is a good fit to the data you input. At the risk of oversimplification tracking is finding a solution (regression) to a set of mathematical equations. You can’t track distorted plates so either you undistort - or the software undistorts under the hood. ![]() Fusion standalone has a 3d camera tracker and is similar cost to Syntheyes - but considerably less functionality. PFTrack is a nice interface but considerably more expensive. You can build 3d geometry in Nuke so can render out to see if it is working. Nuke non commercial will track so could be used to learn - but you can’t export the solve. It also has good tutorials written by its developer. It is the only affordable option, sadly has a terrible 1990’s interface - but is state of the art and used by professionals. I would suggest either giving up and focusing on some other part of 3D or picking up a copy of Syntheyes. ![]() The non-Blender route is I think going to be much more successful learning path but is going to cost. I think it is possible to use Blender for tacking - but in reality I think it is very difficult to learn tracking with Blender. In fact it is worse than difficult it is a very dark art. Tracking is one of those very difficult things that is made to look easy in tutorials.
