Recorder by scripting

Unity Engine
1

Hello everyone, I have a problem for which I cannot find a solution.
I have several cameras on my stage, each camera films a character who makes a single animation.
I want to record in a .mp4 file, for each camera, the animation of my character and that just with a script that I put in an Empty object.
Let’s imagine, I launch with the player button, for each camera, Unity launches a Recorder of twenty seconds, records in a .mp4 file, then activates another camera, relaunch the scene with a Recorder of 20 secs etc etc.

How to drive the Unity Recorder by script ?

Hi Novakissime,

You can create an empty game object, and associate it a MonoBehavior that sets up
your recorders and starts recording on play. For example, you can setup a single recorder like so:

var controllerSettings = ScriptableObject.CreateInstance<RecorderControllerSettings>();
m_RecorderController  = new RecorderController(controllerSettings);

var mediaOutputFolder = new DirectoryInfo(Path.Combine(Application.dataPath, "..", "SampleRecordings"));

// Video
m_SettingsCamera1 = ScriptableObject.CreateInstance<MovieRecorderSettings>();
m_SettingsCamera1.name = "Camera 1 Recorder";
m_SettingsCamera1.Enabled = true;

// This example performs an MP4 recording
m_SettingsCamera1.EncoderSettings = new CoreEncoderSettings
{
   EncodingQuality = CoreEncoderSettings.VideoEncodingQuality.High,
   Codec = CoreEncoderSettings.OutputCodec.MP4
};
m_SettingsCamera1.CaptureAlpha = true;

// Record from a specific camera
m_SettingsCamera1.ImageInputSettings = new CameraInputSettings
{
   OutputWidth = 320,
   OutputHeight = 240,
   Source = ImageSource.TaggedCamera,
   CameraTag = "Camera1"
};

// Simple file name (no wildcards) so that FileInfo constructor works in OutputFile getter.
m_SettingsCamera1.OutputFile = mediaOutputFolder.FullName + "/" + "video";

You can setup one setting for each character, and then start the recording like so:

// Setup Recording
controllerSettings.AddRecorderSettings(m_SettingsCamera1);
controllerSettings.AddRecorderSettings(m_SettingsCamera2);
//...

controllerSettings.SetRecordModeToFrameInterval(0, 1119); // 20s @ 60 FPS
controllerSettings.FrameRate = 60.0f;

RecorderOptions.VerboseMode = false;
m_RecorderController.PrepareRecording();
m_RecorderController.StartRecording();
