Saving image files to make an avi file

[k_norr]

Hello. I am trying to save a bunch of image files to convert to an avi file. I'm using LabView Real-Time 8.2 with a CVS-1450. If anyone has done this before, please let me know how you did it. Also, if you need any more information, let me know. Thanks.

Ken-

      Unfortunately, you cannot use the AVI functions on the CVS since they rely on Windows.  However, you could set up a TCP read and write to pass those images to another computer for processing.  As for how to do it on the other computer you should look at the IMAQ example "Grab and Save to AVI"  There are also quite a few TCP examples if you navigate to the folder Networking in the example finder. Basically, in a loop, you will read those images from your TCP Read and then pass them to the AVI Write frame, just like in the example.  If you have any questions after looking through those examples, let us know.

Thanks, John. Right now I'm saving a whole bunch of images on an external drive and then post-processing them into an AVI file on the host PC. However, I am running into a frame rate problem. I can only get a maximum 15fps from a 60fps camera. After examining my setup, I believe I miscalculated my throughput and something is getting overloaded. I know this is an amateur question, but for a Firewire400 port, it's 400 mega-bits per second, not mega-bytes, correct? That would equate to 50 mega-bytes per second, correct? I just want to make sure I'm getting this right. Thanks!

Ken-

     I think you've got it.  Firewire is 400 Mega-Bits per seccond...or 50 MB/s.  Let us know if you need anything else!
