The settings for the video file can be set on the left side:
Output filename: The output file name for the generated video.
Output format: One of the supported video compression formats can be selected here. The video can also be stored as image sequence in various image formats. In most cases any MPEG-4 codec (XviD, DivX, Microsoft MPEG-4 etc..) should provide good results. For lossless video capture either "Full frames (uncompressed)" or "BMP sequence" can be chosen. However, these methods require an enormous amount of disk space.
Most video compressors can be configured or provide additional information. The "Configure" button can be used to access the compression settings and the "About" button can be used to get further information on the selected video compression format.
If the user has purchased a TerrainView™ license with the “don’t limit video resolution” option, several preset video resolutions can be selected. If a preset is selected with a resolution higher than the actual screen resolution, the width and height values will be cropped.
Width, Height: Width and height of the video. The video resolution is limited to 640 by 480 pixels by default. If the user has purchased a TerrainView™ license with the “don’t limit video resolution” option, the resolution is only limited by the current screen resolution. Note that you can’t create a video with a resolution higher than your screen resolution (due to technical reasons).
Frame rate: Number of frames per second.
How the video is generated can be defined on the right side:
This list allows the selection of the desired recording area. The user may choose between recording only the contents of the 3D window or recording the entire application (”Main Window”). The latter is especially suited for tutorials, because the actions of the user in the GUI are also visible in the video. In 3D window mode the GUI of TerrainView™ will be hidden while the video is being recorded.
Interactive mode, or using flight paths. In interactive mode, the user can control the camera by navigating through the scene. In flight path mode, one or several flight paths are played. The flight path mode creates better videos since TerrainView™ can guarantee enough time to capture the desired frames, resulting in a smooth video.
Flight paths: If in flight path mode, one or several flight paths can be selected to provide the images for the video sequence. All selected flight paths are played during the video is created. If several flight paths with an attached camera are selected, the user has to choose one among them (see below).
Start: Pressing this button will start the recording. This causes a dialog to open which allows the selection of a video compression.
If several flight paths with an attached camera were selected, another dialog will appear to choose the flight path to be used for the camera movement and orientation.
Stop: This button can only be pressed if the recording area is the main window.
