Misc/Replay

The Replay Operator works similar to a video recorder, and can be used for video replays. Playback speed can be adjusted from 0% (freeze frame) to 100%. Video frames are stored in RAM and a maximum of 300 frames can be recorded.

The Replay Operator can be controlled using the Script Engine and Connectors.

For recording of video and audio to disk, the File Target component is a more suitable solution.

• Configuration

  • Start recording on startup - this option will automatically start recording as soon as the project starts.

  • Start recording after playback - this option will automatically start a new recording immediately after playback has been completed.

  • Image quality - use this option to configure the video quality of the recording. The default value is 80. A lower setting will reduce memory consumption but may introduce image artefacts. A high value will improve image quality, but memory consumption will be higher.

  • Default output - this setting affects how the operator works when playback is stopped. The default option is Pass-through, which means that the operator won’t affect the video. The second option is None, which will render a black output.

• Frame Storage

  • Max number of frames - this setting controls the maximum number of frames that can be recorded. The default setting is 100.
