Creating a digital video file from a sequence of images with overlays run within a LabVIEW program?

[FraserD]

I am sequentailly reading individual jpeg files and displaying with an overlay. I was wondering if it is possible to create an .AVI or .mpeg from these individual frames, in order to play the video for the purpose of a presentation?

Yes, you can do it. Check out IVision at:

You can use it from reading the image files to saving it frame by
frame to AVI file with desired compression format or no compression.

Hi FraserD

There is also an example program on ni.com (called IMAQ AVI Read Write Example) that builds an AVI file out of several IMAQ images. It comes with the source code, so it can be modified easily.

Finally, a third option is to use the many AVI or MPEG builders on shareware sites like download.com. It won't be automated, but if you're just trying to make AVIs from JPGs for a one time presentation, then the shareware option may be the easiest.

Good luck

Thanks Kyle.

I'll try these options.
