: few people have Blu-ray recorders.
So, for the time being, the best course is to shoot, edit and save the video (on a hard-drive) in high-definition. Next, make a second copy that’s ‘down-sampled’ to standard definition, so it can be burned onto a DVD. Finally, play the edited disc in an up-sampling DVD player. The result will be something close to the original high-definition movie—but cheap and easy enough to distribute.
In a year or two, when every laptop comes with a Blu-ray burner, you’ll be able to make a fresh copy of the original movie in its full high-definition glory.
But don’t expect the copies to last indefinitely. Blu-ray discs are likely to deteriorate even faster than the ten years or so of DVDs. So, having master copies on a hard-drive will be handy for the grandchildren—provided, of course, they will still be able to read such antiquated devices.
