Recording Settings

This page contains information about the Recording settings that the users can adjust to fit their needs.

Recording Feature

CameraTwin lets you record the incoming stream of every CameraTwin Source. The CameraTwin Recorder is our solution to store the Image sequence and the metadata sequence, consisted of the camera pose and parameters. The user can adjust the recording settings to fit the needs of the project.

Recording Settings Defaults

You can find the Recording settings defaults in the Project Settings -> CameraTwin -> Recorder Default Settings. The default settings are set as initial settings for every newly created CameraTwin Source.

Recording Settings in the Control Panel

Fields

1. “Recording Enabled”: to toggle on/off the recording in UE.

2. “Folder Path”: the location that the recording files will be stored (final and intermediate).

3. “Filename”: [Currently hardcoded to “frame_<timestamp>”] the template of the actual filename for each file of the image sequence.

4. “Image Format”: The file type that the image sequence files will be encoded and stored.

5. “Est. Disk Bandwidth”: According to the selected image format there is an estimation of the required disk write bandwidth. This is calculated based on FHD resolution and at 30 FPS for 4K it will be about 4 times more.

6. “Image Quality”: It’s only relevant for the JPEG image format with 100 being the greatest quality, but resulting in bigger files while lower values reduce the image quality but significantly reduce the file sizes.

7. “Generate Video”: A toggle to automatically create a video from the recorded image sequence and a single file with all metadata related to each frame. For this option to work correctly the user must set the path to the FFmpeg executable in the “Project Settings” ->”Command Line Encoder”->”Executable Path” (video)

8. “Delete Intermediate”: If the user has enabled the video generation and with this option enabled the system will delete the image sequence individual files (images and metadata) and it will keep only the resulting video and the single metadata file.
