# Video in EthoVision XT

EthoVision XT can work with different types of cameras:

Analog cameras

To use analog CCD cameras, you need an encoder board, which converts the analog signal to digital. With this board you can also save the video image to a video file directly with EthoVision XT. See Install analog cameras

Digital cameras

You can plug a digital camera (GigE Vision or USB 3.0) directly into your computer.

The video signal is used directly in EthoVision XT to track live and save video. However, for acquisition the quality of the input signal is crucial, therefore not all digital cameras can be used. See Cameras supported by EthoVision XT

Mixing camera images

You can feed multiple cameras to the EthoVision XT computer. EthoVision XT mixes the images of up to sixteen cameras. Video is saved with all camera images merged into one. For example, when you use two cameras, the resulting video file contains the two camera views next to each other.

For information on the supported cameras, frame rates, and resolutions, and the maximum number of cameras supported, see Camera Installation.

Recording video with MediaRecorder

With the Noldus MediaRecorder software you can record video to be used in EthoVision XT for offline tracking. An advantage of using MediaRecorder is that you can create separate, full resolution video files from multiple cameras. With EthoVision XT, the images from multiple cameras are merged in one video file.
