This is primarily because video cameras simply aren't meant to deliver still image resolutions. QE SuperResolution uses some clever image interpretation to help improve this, examining several frames of video data around the still image you select to create a more complete representation of the still you want to save from the video file. While this doesn't deliver results equivalent to taking shots with a 5 megapixel still camera (or even a 3 megapixel cam for that matter), it does deliver improved results that might even be print worthy at small sizes. The next time you capture something with your DV cam that looks like it would make the perfect slice of time, instead of settling for a grainy image, try QE SuperResolution to beef up the image quality and output a more accurate still."</i> <br /><br /><img src="http://www.digitalmediathoughts.com/images/qesuper.jpg" /> <br /><br />I'll have to give this a try. Getting nice looking stills out of DV is never easy and maybe this can do the trick. What other choices are there for doing this?

I know Sony's Vegas Video can do this. I use the feature often when doing weddings and other events. It's great getting nice stills from the video footage cause everyone looks at the slideshows and printed pictures and wonders how we got that shot.

A little history lesson: this technology was originally developed and used to identify license plate tags on surveilance cameras and police car dashboard cameras. Because cars are usually in motion, a single frame of video is often too blurry to be able to read the license plate. Nasa developed a program called VISAR (http://liftoff.msfc.nasa.gov/news/2000/news-visar.asp) which clears up images using the surrounding frames of video to extrapolate additional image data.
