Video Capture Module for Windows

Overview:

The MLS320/7 Video Capture Module for Windows is used for simultaneous recording and synchronization of a Windows Media Video movie and a LabChart data file. It allows the user to record a movie directly to computer using a personal video camera. The movie is then saved and linked to the LabChart data file.

Recorded movie and LabChart data file can be played back together allowing users to observe what is happening in the movie simultaneously with any point in the recorded data, or vice versa.

The Video Capture Module should be used with the latest version of LabChart. The Video Capture Module is also available as part of LabChart Pro.

The LabChart Pro software package includes all LabChart Modules. Existing LabChart users and PowerLab system purchasers can upgrade to LabChart Pro at a special price. If you need more information please contact your  ADInstruments Representative.

For more information download the Software Booklet (5.83 MB) or contact your nearest ADInstruments Representative.

Sample Applications:

Video Capture Module applications include studies that require video observation with data acquisition. Sample applications include:

• Exercise Physiology
• Sleep Studies to permit supplementary behavioral observations of a sleeping subject
• Speech Studies for synchronizing laryngeal stroboscopy images (Laryngograph Ltd) with physiological data obtained using PowerLab data acquisition unit.
  
• Animal Studies for example, in a frog heart experiment the ventricular contractions can be recorded as a movie while contractile tension is simultaneously measured with a force transducer and recorded using LabChart.

Features & Benefits:

• Simultaneously record and synchronize a Windows Media Video movie and LabChart data.
• Suitable for use with a wide range of video cameras or capture cards.
• Automatic separate storing of movie recorded as .wmv file and LabChart data as .adicht file.
• Video playback maintains time synchronicity allowing easy illustration of visual/physical changes associated with mechanical recording.
• Camera Preview window showing live preview from the camera useful for initial setting of image quality.
• Video Capture Settings Dialog allows for selections including
• Recording: Basic recording settings including selection between video and/or audio recordings, control of start/stop recording and the quality of recording. Automatic scanning of computer for available disk space free for recording use and notifies the user regarding the possible length of recording
• Devices: Selection of available devices and adjust video and audio settings. Video settings such as zooming, focusing, and exposure can be set manually. These can be saved for subsequent experiments using the same devices
• Synchronization: Synchronizes recording devices with LabChart to allow frame-accurate video/data recordings, by accounting for the delay between the recorded video and the LabChart data. (Please note that synchronization is dependent on the communication interface and computer performance. Hence a manual synchronization adjustment is provided).
• Cache: Allows selection of temporary location in hard disk to store recorded movie files and allocation of free disk space in computer to store movie recording.
• Dragable Movie Marker for easy navigation between LabChart data or movie frames. Alternatively, users can scroll within the movie and correlate each point in the movie with the corresponding point in the data file.
• LabChart data files can be edited, for example a range of data can be deleted. This results in separate data blocks, each with a corresponding movie file.
• In-build Video Capture Tutorial to guide users through initial video recording set up in LabChart, including hardware connections, settings, synchronization, recording and analyzing.
  

Important Notes: Video Capture works with video cameras and video capture cards that support DirectShow. Synchronization is dependent on the camera’s and computer’s specifications (Dual and Quad Core computers are recommended). User adjustment is possible through the Video Capture Settings dialog. Movie files can be edited in external programs to comment, annotate and visually enhance the video. Timeline changes should not be attempted as this break the synchrony with the data file.
