Capture iPhone Footage and 3D Tracking Data at the Same Time with This Free App

CamTrackAR
Camera tracking after the fact isn't easy. Here's a way to do it while you're shooting for free. 

FXHome is known for HitFilm, popular desktop software that combines editing, compositing, tilting and 3D tools in one filmmaker friendly suite. With the release of version 15, the chroma key, auto-stabilizer, and motion tracking options are some of the best in the biz. Also, there's a free version of HitFilm that you can test drive, and it's Pro version supports GPU-acceleration to speed up editing and cut down on rendering times.  

The company has released its first smartphone app, called CamTrackAR. As the name suggests, it can capture video and 3D track the data simultaneously using Apple’s AR technology. This is awesome news, especially if you have ever tried to track a camera's movements after the fact. FXHome is marketing the tool for those in the previs world, but it's going to be great for any filmmaker looking to get a leg up when it comes to visual effects or conceptualizing scenes.  

Let's say your company offers previs work as a means of storyboarding or creating visual effects. By simply using an iPhone and the app, you can shoot the scene and the app will track the data for you. Data will be saved as a HitFilm (.hfcs) file, a Blender (.py) file, and a single point anchor to allow you to further edit in post, which should save loads of time. This app is a great way to get a rough estimate or use as a starting point for finished work. 

The interface is straight-forward and easy to use. You can set your floor plane with a green tracking grid and add anchor points by simply using your finger. After pressing record, the app does all the work ensuring that anything tracked stays locked in place. 

While the basic version of the app is free, there is an upgrade option that allows you to export to After Effects (.jsx) where you can add multiple anchor points to a scene. FXHome offers the upgrade as a perpetual license for $29.99 or in subscription form for $4.99. This way you can try it for a month, and if it isn't for you, you're not stuck paying the full bill.

For now, the app is only available for iOS devices. It can be downloaded for free here. FXHome has also published a step-by-step guide in how to use it.

So what are you waiting for? Go create.

Maybe it's just because it's shot and tracked on an iphone, but this tracking looks pretty horrible to me. Yes it's cool that it can all be done on a phone or ipad while you shoot. That's super convenient. But only if the track is actually good. And every example they show in the promo wiggles, shakes and gets off track. Every shot. It would make the actual track for anything other than a poor youtube video unuseable and you'd have to track the old fashioned way anyway.
