Save to AVI with IMAQdx


Recommended Posts

Hi, I have a little problem with IMAQdx blocks and saving to AVI. I wanted to make a circuit for grabbing and saving to AVI from the example - Grab and Save to AVI.vi. It is allright, but I a need to replace IMAQ blocks with IMAQdx. When I do it, it looks well, the grabbing is functional, but there is a problem with saving to AVI. I cannot get Image Type property from IMAQdx first block, so an error occures - Invalid Image Type. When I connect an image type constant (Grayscale, RGB,...) to IMAQ Create block, the problem is the same! What to do with this? How to adjust left side correctly? Thanks.

The problem is solved! The problem was in camera mode, I had to choose the right mode to has valid image to avi.

Or you need to down-convert your Image Refs to the proper format before storing to AVI (it can only handle U8 grayscale or 32-bit RGB images).

Yes, you are right. Can you tell me how to do it and what to use? Thanks

If you are using NI-VISION then you can use the IMAQ Cast Image.vi. You probably don't want to modify the existing Image Ref, in that case you need to wire in a new Image Ref to the Image Dst input of this VI.
