creating AVI

[polymer]

Hi all,
           I am having a recorded AVI file in which I want to add text as a overlay at particular position. I was able to add the overlay at particular position on a particular frames. But I don't know how to write all this as a new AVI.

Having LabVIEW and VISION 7.0

Any help greatly appreciated.

Prasath,

You will have to use the IMAQ Merge Overlay.vi to destructivley add your overlays to the image data - this can then be written to an AVI. Overlays are not actually a part of the image and do not change the image data until a merge is called. AVI's do not have the ability to save overlay data - only image data, so a destructive merge must be done to permanently make the overlay part of the image.

This link give a few more example of using overlays:

Hopefully this puts you on the right track.
