Set up your system
Videos from different cameras can be combined into one file. Choose to have up to four camera inputs displayed in four equal quadrants (Picture-by-Picture, PbP) or to display up to three small video images in one main video image (Picture-in-Picture, PiP). Where you can record eight video streams, PiP and PbP is limited to four. PiP allows you to choose the position of the embedded video images within the primary video and then identify which image comes from which camera with a superimposed number on the camera image.
Record rapidly occuring behaviors
In particular, when one is studying rapidly occurring behaviors, it is ideal to record videos and score them afterwards with The Observer XT. The playback functionality of The Observer XT allows you to play back the videos at a low speed, and score behaviors in greater detail.
The key to synchronization is integration. When you use MediaRecorder, you do not have to worry about the data synchronization, because MediaRecorder can record up to eight files in sync. Additionally, you can command MediaRecorder from another software program to start and stop recording. By controlling MediaRecorder from The Observer XT, for example, you can manage all your data with one application.
Besides using MediaRecorder as a stand-alone tool, it can also be used in The Observer XT or in EthoVision XT. Special protocols can be defined to start and/or stop recording of a video file while scoring data in The Observer XT or video tracking in EthoVision XT is done.
