The Rapid Review feature lets you export video at a higher playback speed than the original recording. (Sometimes this is called "timelapse" mode). When you specify either the export playback speed or length of the video, the corresponding value and the Frames interval will adjust accordingly. Note that the source video must be at least 10 seconds long for this option to be available.

To Apply Rapid Review Export

1.Select the desired device.

2.Select the time span you want to export and use the Timeline context menu to open the Export Video dialog (right-click on the newly selected area highlighted in blue).

3.In the Single Camera tab, click on the Rapid Review button. (It may be necessary to select a different output format to enable the button.)

4.The Rapid Review panel that opens to the right of the preview will show the Initial video length of the selected segment for reference. Set a value for each of the following:

•Exported video length – Enter a desired duration in seconds, where the shorter the exported video, the faster the playback speed will be.

•Speed – Use the slider to set the speed increase from 10x to the maximum available value. (The maximum speed multiplier depends on the initial video length.)

Note: The Exported video length and Speed values are related. The shorter the length, the faster the playback speed and the higher the frame interval. The slower the speed, the shorter the video and the lower the frame interval.
