Recording ARKit as Video

One method is to use `RPScreenRecorder.shared().startCapture` instead of `RPScreenRecorder.shared().startRecording`

But this will capture the entire screen, not just the ARSCNView

RPScreenRecorder.shared().startRecording works for me but when I dismiss the previewViewController, the ARSession is frozen.

Which physical iPhone device are you using? I was tring on an iPhone SE

I had this problem too on 6s. Solved with recreation ARSCNView after dismissing preview controller.

But ReplayKit also captured all controls. Is there any way not to capture them?

The only *solution* Ive found is just when I record, show a count down, then hide all of the controls and record, when the user taps the screen, stop recording and bring back the controls. ugh.

I found a solution. You can use SCNRenderer with ARSCNView scene property. Take scene snapshots using `- (UIImage *)snapshotAtTime:withSize:antialiasingMode:` and combine them into video.

I just published a new framework for ARKit, called ARVideoKit.

ARVideoKit enables developers to capture and record ARKit videos, photos, Live Photos, and GIFs!

Using SCNRenderer I was able to render frames from ARSCNView and using material diffusing I was able to render ARSKView frames too!

Which means, NO MORE screen recording / screenshots to capture media of your awesome ARKit apps!!

Check out the framework here: https://github.com/AFathi/ARVideoKit

Hi Amhed,

That sounds pretty cool.

Does it work only with ARSCNViews or will any SCNView work?

How can I attach audio at the same time?

Thanks!

Okay that makes sense -- how do you combine them to a video?

And how to add audio?

Hey @drewster,

I just recently open-sourced ARVideoKit and that will allow you to easily configure the framework and use both AR and non-AR SCNView/SKView!

Feel free to clone/fork the project: https://www.github.com/AFathi/ARVideoKit

Additionally, ARVideoKit allows you to easily record audio while rendering a scene's content.

Thanks Ahmed,

Your pod seems ideal, but it makes my app freeze!

AR is already quite expensive and it seems that your code adds another renderer on top?

Hey,

I solved this by creating a HUD that is on a different window. ReplayKit doesn't record this.

Hey Ahmed,

I tried using this and it would record my objects in the wrong location - do you know why this may happen ?

O

ARCapture framework allows to record video from ARKit. It's lightweight, well documented and can be extended if needed. Moreover, it has no memory leaks.
