MVStudio is a Qt based visual interface to a set of cameras connected to a PC cluster. MVStudio gives the user the ability to synchronize the cameras, change their parameters, and record or play back multi-camera video sequences. 

We developped a new software with a graphical user interface (GUI), to remotely control the acquisition, synchronization and display of video streams from multiple cameras (up to 64 cameras) arbitrarily distributed on a grid of workstations. The software can be used as a recorder, in which case it controls all camera parameters (e.g. gain, shutter speed, focus, white balance) through the IEEE 1394 interface. The software allows the hardware configuration to be dynamically modified, and the control of either hardware or software synchronization of all cameras. The software controls remote processes which are responsible for recording the video streams on disk with frames rates up to 30 frames per second and resolutions up to 800 x 600. The software displays the video streams from all cameras simultaneously in reduced resolution during recording.

The software can also be used as a video player, allowing the synchonized display of all recorded video streams simultaneously, and as well limited video editing functions.
