I learned that closeups tend to look better than wideshots. Something I suggest you do before printing, is to color correct.

More than likely you'll have to increase saturation. Give it just enough to add color but dont' over do it. You know you over did it if the color bleeds on your print or the faces are orange(looking like an oompa loompa)

Video is very flat. I suggest adding the curve filter to make the highlights 'pop' and make the shadows darker. A simple s curve would do and would greatly improve the results.

Try not to over due the saturation and curves. just give it a subtle effect. Other than that, make sure you have good photopaper and a good printer.

Also depending on the picture, I like to duplicate layer, small blur and decrease opacity. This gives it the dreamy look and more importantly it does a good job at hiding any pixelation.

Make sure your frame grab is interlaced and not just one field
