| [bitRateMode](/engine/6000.6/script-reference/unityeditor/media/videotrackencoderattributes/bitratemode.md)     | The [VideoBitrateMode](/engine/6000.6/script-reference/unityeditor/videobitratemode.md) for the encoded video. |
| [frameRate](/engine/6000.6/script-reference/unityeditor/media/videotrackencoderattributes/framerate.md)         | The frame rate for the encoded video, in frames per second, expressed as a fraction.                           |
| [height](/engine/6000.6/script-reference/unityeditor/media/videotrackencoderattributes/height.md)               | The image height in pixels.                                                                                    |
| [includeAlpha](/engine/6000.6/script-reference/unityeditor/media/videotrackencoderattributes/includealpha.md)   | True if the track is to include the alpha channel found in the texture passed to AddFrame. False otherwise.    |
| [targetBitRate](/engine/6000.6/script-reference/unityeditor/media/videotrackencoderattributes/targetbitrate.md) | The target bit rate for the encoder.                                                                           |
