Shoot on your iPhone with CamTrackAR and then build a 3D scene in Motion automatically.
It's not an attention-grabbing headline, but this is big news for Apple Pro App users. We hinted back in January of this year that having media and the tracking data from CamTrackAR would open up many different creative possibilities for those who use the Apple Pro Apps.
Well, we are very pleased to say that FXHome has now issued an update to CamTrackAR that supports Apple's Motion!
So what does it do and how does it work? The main point here is that to get items into a pre-shot scene normally requires tracking with an editing or VFX app, with or without a third-party plugin.
Footage shot with CamTrackAR completley bypasses this step by generating a Motion project (Er, hang on is this the first instance of a Motion project being made on an iPhone?) that consists of a 3D scene with a camera and the original footage.
Any extra layers such as text or a 3D object will then get placed in the 3D scene and move as if they were there when the footage was shot.
The example below took about two minutes to build, including shooting the scene, transferring the files by AirDrop, opening the Motion project and adding the 3D text. It is that quick!
The slight twitches in the video are due to me forgetting to turn off the autofocus, but a pretty good track nevertheless in seconds. In the screengrab below, you can see the keyframes that have been set automatically by the CamTrackAR Motion project export.
This won't work on footage that hasn't been shot on CamTrackAR and your phone needs to qualify, certainly an iPhone X works, but you might get better tracks with a LiDAR phone.
The new version of CamTrackAR is free to download on the Apple App Store. This version allows you to shoot, export the tracking data as a Motion project and render out a watermark-free result in Motion.
The fully featured version is available for $4.99 per month or $29.99 for a permanent license. That gives users access to 3D model import, broadcast-quality chroma key (green screening), and multiple positional points in the app, as well as tracking data export in .jsx (After Effects), .fbx (Autodesk), .json, and .csv formats.
Now, a couple of points here. First is it doesn't look like there is a demo video yet for using CamTrackAR and Motion. It is super simple to work out though and this earlier demo video gives you examples of what can be achieved.
Secondly, at the the moment, CamTrackAR only supports 30 and 60 frames a second, so unfortunately that makes it less than optimal for us in Europe.
Lastly, the Motion project that it created from an iPhone 10 was 1920 x1440 - so you'll have to do a bit of reformatting of the project to get it into 16:9. We tried to shoot in 9:16, but that completely confused Motion because as the camera is keyframed, you can't just rotate everything.
But... To put it simply, CamTrackAR is amazing and works so quickly to produce good results. We recommend you check it out, especially as the Motion integration is free.
Will this be the new toy of creators? Will we see YouTubers appearing in 3D scenes? The tools are out there...
