The MLS320 QuickTime Capture Module
for Macintosh is used for simultaneous recording and synchronization
of a QuickTime movie and a Chart data file. A personal video
camera is used to record a movie direct to your computer.
The movie is then saved together with the Chart data
file.
The QuickTime Capture Module should be used with the latest version of Chart. Click here for the latest Chart update for Macintosh.
Features and benefits include:
The QuickTime Capture Module allows for the simultaneous
recording and synchronization of a QuickTime® movie and Chart data.
The data and the movie can be played back together, allowing
you to observe any effects on the data caused by events during the experiment.
For example, in a frog heart experiment the ventricular contractions
can be recorded as a movie in QuickTime while contractile tension
is simultaneously measured with a force transducer and recorded
using Chart. By playing the movie and data file together it is easy to illustrate
the visual/physical changes associated with the mechanical recording.
The example above shows a simultaneous Chart and
QuickTime recording
of grip force measurement.
QuickTime Capture is also useful in the teaching market, for example
in developing demonstration recordings of experimental
techniques or for presentations during classes that require
both data acquisition and experimental observation.
The Capture settings dialog box allows the selection
of video and/or audio recordings, movie size options, hard disk
space allocation.
QuickTime Capture includes two standard QuickTime settings dialogs. These are for adjusting settings specific to the recording devices you are using.
The video settings include the type of compression and frame rate used, contrast and brightness settings and the input source if more than one camera is connected.
The audio settings include the type of compression, sampling rate, and input source if more than one sound recording device is connected.
The Camera Preview window shows a live preview
from the camera. This is useful for the initial setting of
image quality. When satisfied with the camera image, the user can
start the recording. The recording of data in Chart and the recording
of the movie, both start simultaneously by clicking the “Start”
button in Chart.
The Movie Marker feature can be used to show
the point in the Chart data file corresponding to the current movie
frame. This is useful when trying to find the exact data point
corresponding to a particular experimental event, or vice versa. The
user can navigate through the data or movie frames by dragging the
Movie Marker in Chart.
Alternatively the user can set an active point or make a selection
in Chart and then choose Set Movie Position from the Capture menu to
go to that point or selection. The chosen selection of the movie can
then be played.
The Quicktime Capture Module is also available as part of Chart Pro. Visit the Chart Pro information page prior to making a purchasing decision. Existing Chart users and PowerLab system purchasers can upgrade to Chart Pro at a special price. If you need more information please contact your ADInstruments representative.
