NatCorder

NatCorder is a high performance, cross-platform video recording API for Unity Engine. First, create a recorder:

// Create a recorder
var recorder = new GIFRecorder(
    640,  // image width
    480,  // image height
    0.1   // frame duration
);

Next, commit a bunch of video and/or audio frames to the recorder:

// Commit video frames
Texture2D[] frames = ...;
foreach (var frame in frames)
    recorder.CommitFrame(frame.GetPixels32());

And when you're all done, finish writing and use the video as you desire:

// Finish recording
string videoPath = await recorder.FinishWriting();

NatCorder comes with a rich featureset including:

• Record any texture, anything that can be rendered into a texture, or any pixel data.
• Record to MP4 videos and animated GIF images.
• Control recording quality and file size with bitrate and keyframe interval.
• Record at any resolution. You can specify what resolution recording you want.
• Get the path to recorded video in device storage.
• Record game audio with video.
• Support for recording HEVC videos.
• Support for Android, iOS, macOS, WebGL, and Windows.
