Answers to Common Questions

What is NatCorder?

NatCorder is a high-performance, cross-platform video recording API. With NatCorder, you can record MP4 videos, animated GIF images, JPEG image sequences, and more.

Can I try NatCorder for free?

Yes! NatCorder offers an unlimited-time free trial. The trial does have certain limitations though:

  • Only the MP4Recorder can be used. Creating any other recorder will throw an exception.

  • Recorded videos will never contain any audio.

  • Recorded videos will have a prominent NatML logo watermark.

  • Recorded videos will have their long side capped to 480 pixels.

To lift these limitations, you will need an active NatML VideoKit subscription.

What is an Access Key?

In order to use NatCorder, you must authenticate yourself with a valid NatML access key. You can find your access key on your NatML Hub profile page. Once you retrieve the access key, place it in Project Settings > NatML.

Keep your access key secret! Anyone with your access key has almost full access to your NatML Hub account.

Will my apps require an internet connection?

No! When you build your app from Unity, NatCorder will generate a session token that contains all the necessary information needed for you to use the API. At runtime, this token is validated without an internet connection. Minimal information is used to generate the token, and no information is collected from your users at runtime. See the code:

What happens if I cancel my subscription?

If you cancel your VideoKit subscription, NatCorder will automatically revert back to the free trial mode in both the Unity Editor and in new builds from Unity.

Any existing apps you have built from Unity will continue to function as-is.

Are recorders cross-platform?
