How can I get maximum frame rate from a webcam?

share|improve this question
More details would be useful, for instance what webcam model and what you're trying to do. Why is the frame rate limiting you? What is your OS? –  Raystafarian Apr 2 '12 at 11:42
I just wish to know what the maximum is; I actually am not sure what model it is, I was going to set a parallel question for finding that out. It just comes up generic. It looks like a C270 by Logitech though. –  Cenoc Apr 2 '12 at 11:45
Try opening it as a stream using Media Player Classic, or VLC. –  Breakthrough Apr 2 '12 at 12:20
I'd start with the manual. –  Oliver Salzburg Apr 2 '12 at 12:28
This isnt my webcam, and I dont have the manual, but thanks for the suggestion. –  Cenoc Apr 2 '12 at 15:18

Well... first...

The QuickCapture software application video recording default is 15 FPS. This setting was chosen because Logitech feels that it provides the best overall image quality with reference to their RightLight™/RightLight™2 Technology.


In order to capture video at 30 FPS, third-party video recording software will be required.

Now, they go on to state what settings are necessary, how you would need to adjust the "shutter speed" (there is no actual shutter though), how using the Low Light Boost might severely drop the frame rate to as low as 5fps, etc. But, the important info.... well... read for yourself...

A QuickCam® Pro 9000 can physically output 30 FPS at 640x480 resolution, 30 FPS at 800x600 resolution, and 15 FPS at 960x720 resolution (MJPG).

For most applications, you will be limited to approximately 10 FPS (USB bandwidth limitation of 12 Mbps), unless your camera is detected as an Enhanced USB 2.0 device (480 Mbps).

160x120 x 24-bit color x 30 FPS x (format) = 9,216,000 bps(9.216 Mbps)

320x240 x 24-bit color x 9.766 FPS x (format) = 12,000,000 bps(12.000 Mbps)

640x480 x 24-bit color x 2.441 FPS x (format) = 12,000,000 bps(12.000 Mbps)

320x240 x 24-bit color x 30 FPS x (format) = 36,864,000 bps(36.864 Mbps)

640x480 x 24-bit color x 30 FPS x (format) = 147,456,000 bps(147.456 Mbps)

800x600 x 24-bit color x 30 FPS x (format) = 230,400,000 bps(230.400 Mbps)

960x720 x 24-bit color x 30 FPS x (format) = 331,776,000 bps(331.776 Mbps)

1280x960 x 24-bit color x 24.414 FPS x (format) = 480,000,000 bps(480.000 Mbps)

In short, it depends on the software you are using to take the video from the camera, the type of USB connection, the size of the image you are getting from the camera, and the capture settings WITHIN the software.

So... without more specific information from you, no more specific information could be given to you.

Are you saying that the webcam has no manufacturer markings on it at all, that could be used to figure out the exact product you have?

If it isn't built-in and if you haven't already done so, flip the webcam over and look for any part numbers that could be used to figure this out.

If it is built-in, then tell us what model of computer it is, and that should get us going down the right path.

In both cases, we can then figure out the specifications of the webcam, and also which drivers you need to download and install, so that your computer makes best use of the webcam and enables it to get the specified framerate.
