Does your Spectra 8 card captures audio as well as video ?

Does Spectra8 come with applications?

Can you explain this statement a little better: "four simultaneous inputs at 30 fps (120 ftps total) or 8 inputs at 15ftps (120ftp total)?

You say that the card works with popular video capture software. How does the software handle 4 simultaneous inputs? Most software is only looking for 1 input?

Will the card handle a mix of NTSC and PAL inputs at the same time?

Can real-time video be displayed and recorded at the same time?

What type of quality can I expect at 640x480 and 30fps on 4channels?

Can I record TV shows with this card?

I have several wireless cameras that go into a receiver...the receiver has a RCA video out...so what I need is a video card, install it in my computer, and watch the cameras on my computer screen.

Technical Issues

I've installed my Spectra8 and it's not working.

I'm not getting a video display (black screen).  What do I do?

My video is "scrambled." What do I do?

My video looks very "grainy." How can I fix this?

I'm getting lots of "dropped frames" when I capture video.  What should I do?

There is  some latency when all four inputs are being used and the system is overloaded.

Note: Before installing Spectra8 driver, please check if you have the BT878 driver installed on your computer. If you do, please uninstall BT878 driver completely. Otherwise it could have a compatibility problem with the Spectra8 driver

Does your Spectra 8 card captures audio as well as video ?
The Spectra8 card does not have audio capture capabilities (even if you see an audio driver associated with the card). The solution is to use separate audio capture cards for the job.

Can you explain this statement a little better: "four simultaneous inputs at 30 fps (120 ftps total) or 8 inputs at 15ftps (120ftp total)?

The card has 4 true capture inputs that can sample at 30fps each, a total of 120fps per card. However, you can 'split' each input into 2 inputs at the cost of lowering the frame rate.

You say that the card works with popular video capture software. How does the software handle 4 simultaneous inputs? Most software is only looking for 1 input?
You can bring up multiple instances of your software and each time select different capture devices (1,2,3,4).

Will the card handle a mix of NTSC and PAL inputs at the same time?
Yes, the card handles NTSC/PAL/SECAM

Can real-time video be displayed and recorded at the same time?
Yes, this is up to the application developer.
 

What type of quality can I expect at 640x480 and 30fps on 4channels?
640x480 at 30Ftps is almost broadcast quality, maybe better than VHS, lower in quality than DVD. However, you need to ensure that you have a good system to do this.

Can I record TV shows with this card?
The Spectra8 has composite inputs, you need a tuner to convert RF into composite so that you can feed it into the Specrtra8.

Does Spectra8 come with applications?
The card comes only with drivers, no applications. However, you can use any frame-grabber application to view the inputs (launch separate instances if the software is not capable handling multiple inputs). For example, you can use Windows Media Encoder 7.1 or 9.0 Beta, RealProducer, etc.

I have several wireless cameras that go into a receiver. The receiver has a RCA video out. What I need is a video card, install it in my computer, and watch the cameras on my computer screen.
Yes, you can take multiple outputs from your video source in RCA format and feed them into the Spectra8 card so that you can preview on a PC. You would need RCA to BNC adaptors because the Spectra8 card uses BNC as input.

Technical  Issues
I've installed my Spectra8 and it's not working.
  • Verify that the board is completely seated in the 16-bit or 32-bit (E)ISA slot inside your PC.  These slots are usually black or brown.   The board should be level and attached to the chassis using the mounting screw.
  • Verify that all of the cables are connected securely to the proper board. 
  • Verify that there is no other video capture card installed on the computer.  If there is, remove the other card.
  • Reboot your computer after installation.

I'm not getting a video display (black screen).  What do I do?
  • Verify that your video source is properly connected to the Spectra8 board and powered up.
  • Make sure the physical jack used for the connection is the same as the one selected on the Video Control panel.

Composite selects the RCA jack, S-Video selects the 4-pin mini-DIN, and MXC selects the multimedia extension connector.

My video is "scrambled." What do I do?

If your video display is scrambled or video is displayed in the Video Control Panel but not in the application window, try the following:

  • Verify that your NTSC/PAL setting is correct for the type of video source you have
  • Verify that your video capture format is compatible with the applications; see the documentation for the application.
  • Verify the recommended image sizes and capture formats from your application
  • Restart the application.

My video looks grany
If your video display looks grainy, set your display High Color (16-bit) or True Color (24-bit).
 

There is  some latency when all four inputs are being used and the system is overloaded.

The latency issues are not from the card, they are from the encoders you are using.
Regarding system load: Keep in mind that you are processing 4 live streams at the same time and that can generate a lot of PCI bandwidth.
If  frame dropping occurs, lower the encoding settings by selecting lower frame rates or lower resolution or increase your CPU speed.
