FilmRiot posted a lengthy "test video" online last month that goes into more detail about a somewhat atypical app for mobile filmmakers. CamTrackAR is a 3D tracker for Apple's iOS devices.
At first glance you might think, what the hell am I supposed to do with a 3D tracker on my smartphone, but FilmRiot shows in great detail where the advantages over a tracker can be found in compositing.
Basically, there are two: Firstly, the tracking data can be used directly in the iPhone if the device is already being used as the main camera. is already used as the main camera. And secondly, the biggest advantage in our eyes:
You can use the app to walk through a scene before shooting and set virtual tracking points by touch gesture. If you then shoot your clips through the same lens, the app already knows the tracking points it is supposed to follow very precisely - and can match them even more correctly with its "predefined spatial understanding". At least that is the theory.
For further processing, the tracking data can then be exported to Blender or Hitfilm. And those who own the purchase version can also export to After Effects.
FilmRiot describes the workflow with After Effects in detail in his video, so that even newcomers to the subject can get a good idea of how such an "app tracker" can be used profitably for their own projects.
Whether the results are better in the end than, for example, the Blender Tracker, which is already known to be very good, is difficult to judge. We assume heretically that the export to Blender is perhaps also possible free of charge, because here you might get similar results for free anyway.
But we don't know anything at first, and it doesn't seem to cost anything to try it out. However, anyone who wants to use the tracker sensibly currently pays 5 dollars a month or 30 dollars once.
