CinePlex Digital Video Recording and Tracking System

CinePlex Data Sheet

CinePlex Capture Features

• User-defined, tracking region of interest
• Video capture that can be synchronized with neural recordings from the Plexon Multichannel Acquisition Processor (MAP) or Plexon Recorder
• Standard video .avi files in Motion JPEG format
• Selectable image quality setting
• Flexible input and output (I/O) options
• All-digital imaging with Imaging Source™ camera (640 x 480 resolution, 30 frames per second)
• Optional tracking feature that provides three methods for real-time animal position tracking: body contour using image contrast, colored LED lights on headset (up to three colors) and reflective color swatches
• Recording of contour motion across adjacent video frames to detect freezing behavior in fear-conditioning experiments

CinePlex Markup Features

• User-defined, zones of interest for automatic insertion of entry/exit events
• Integrated viewing of neural data files
  (Plexon .plx, NeuroExplorer .nex) and .avi files
• Full digital video recorder (DVR) playback capabilities
• Display of tracking position data overlaid on video
• Video-aided insertion of event markers and intervals
• Removal of temporal segments of neural data during artifact-generating behaviors (chewing, grooming, etc.)
• Ability to edit position data from CinePlex Capture and to manually enter new coordinates
• Seek and search based on event markers
• Save neural data to Plexon (.plx) and NeuroExplorer® (.nex) files, or export to Excel®, MATLAB® or text files

Description
CinePlex is a digital video recording and tracking tool that enables the synchronization of video with neural data files. The synchronized video, tracking coordinates, and neural data can then be played back offline, where behavioral event markers and time-interval variables can be inserted. The marked-up data can be exported for further analysis.

CinePlex consists of CinePlex Capture and CinePlex Markup.

CinePlex Capture. CinePlex Capture is a hardware and software solution that enables the simultaneous capture and recording of synchronized video and generates real-time tracking coordinates.

Typically the CinePlex unit is used in conjunction with the Multichannel Acquisition Processor (MAP). The CinePlex Capture processor receives and processes raw video from a Firewire camera.

CinePlex compresses and stores the captured video on the hard drive, as an .avi file. The MAP signals the CinePlex processor unit to start, stop, pause and resume recording video to the .avi file. The MAP system also provides a clock signal that enables CinePlex Capture to time stamp each video frame.

Tracking Option. The available tracking option enables CinePlex Capture to analyze each frame of video data to determine the positions of the objects being tracked.

The processor unit encodes this position information digitally and sends it back to the MAP system through the capture cable where it is saved directly into the neural data file. This position data information is also available to online user-written programs.

The video, tracking, and neural data can then be imported into the CinePlex Markup software to visualize the data and define new event markers and time intervals.
