I've never tried it with video, but used to do it with super8 film back in the day with acceptable results. We used a blue filter (with video you might be able to cheat the white balance enough by balancing on something orange) and avoid shooting the sky, as that spoils the illusion. Underexpose just a little, and it works best if there is direct backlight or edgelight on the subjects (cloudy days are bad, and avoid shooting directly frontlit) Experiment a bit. Tape is cheap.
