Q: I installed
QuickTime Broadcaster and now VideoPoint® Capture will not open. What
do I do? (Mac only)
A:
The installation of QuickTime Broadcaster corrupts the VideoPoint® Capture
preferences so you need to delete the plist for VideoPoint® Capture. The
plist is located at: (username)/Library/Preferences/com.vpcap20.plist
. When you restart VideoPoint® Capture you will need to agree again to
the end user license.
Q: I upgraded
to Mac OS 10.3xx (Panther) and now VideoPoint® Capture is not working
correctly. What should I do? (Mac only)
A:
First you should reinstall the VideoPoint® Capture application. You should
then reinstall the capture hardware driver. Shut down your machine and
restart.
Q: I get an error
message stating that the device can not be connected.
A:
Either your device is not compatible with Video For Windows or there was
not enough memory to complete the last operation. In that case, free up
more memory by closing other open programs, or by assigning more memory
to the capture program. Sometimes just restarting your computer helps.
Q: How can I capture
at 60fps?
A: In order
to capture at 60 fps, you need either: " Digital Camera connected over
FireWire " An analog capture card that claims to capture 60 fields per
second AND you must set the capture size to 640x480 (or equivalent)
Q: My movie has
a few duplicated frames, what should I do?
A: Duplicated frames have a few causes: " Capture Rate set too high "
Movie Captured from a rented videotape (or any video that was once on
film). If the movie was once on film, you should do the film-to-video
correction in the Corrections Menu. See the user guide for more details.
If this is not the case, you should try setting the capture rate to a
lower value before capturing.
Q: Why can't I
see any video when I want to capture?
A: Your video source may not be connected properly or the video capture
settings may not be correct. To fix that, open the video settings (from
the capture options menu) and try different settings. Sometimes, just
the process of opening these dialogs will correct the problem.
Q: There are a
lot of yellow bars under my captured movie, indicating dropped frames.
The movie is jumpy.
A:
If the capture rate is too high, the hardware will not be able to save
the frames as fast as they are coming in. Hence, it drops or duplicates
them. It may also be that your drive is fragmented, causing the software
to look all over the place for available disk space. De-fragment the hard
drive that contains the capture file.
Q: After I capture
a movie I get only a white (or blue) screen. (Windows only)
A: This is an installation problem. Reinstall QuickTime, but do a "Custom"
installation and choose all the components (default installation leaves
out some components needed for capture). Also make sure that you have
the latest versions of QuickTime and DirectX.
Q: What frame
should I choose for my first frame?
A: Choose a frame that would make a logical choice for time=0. For example,
if you are looking at the projectile motion of a basketball, you would
choose the first frame in which the ball is free of all forces (except
gravity). This makes the analysis easier since a curve fit to your data
would not be affected by a point which is not subject only to gravity.
Q: What should
I choose for my last frame?
A: You should choose the frame which contains the last motion that you
want to analyze. For example, for a projectile, you would choose the last
frame in which the projectile is a) visible and b) not under the influence
of forces you are not interested in.
Q: After I choose
"double" frames, the movie still has the same number of frames. Why?
A: The de-interlacing (which effectively doubles the number of frames),
does not take place until the 'save' process. This saves time and image
quality at the expense of being a little confusing.
Q: What kind of
equipment should I buy?
