Rules of thumb

[Steve Grisetti]

With standard DV editing, we've found that about 60-70 minutes of video fits on a standard, single-sided DVD before the program must degrade quality to fit.

Is there an equivalent rule of thumb for HDV and BluRay? How much HDV footage can you fit onto a BluRay disk and still maintain the highest quality?

Thanks.

With HDV at the HDV standard of 25Mb/s you can fit about 20 minutes on a standard DVD... compared to 1 hour of high quality standard definition. So as Blu-ray is the only high definition format now... a 25GB single layer disc will fit approximately 2 hours or 4 hours on a dual layer Blu-ray disc.

If you are using AVCHD at 15Mb/s you can fit proportionately more video on a Blu-ray disc.

Beautiful answer. Thanks again, Paul!

If I understand this correctly, I can burn a 20 min high def video on a standard DVD. I assume this can be played on a DVD player and be High def (on a high Def TV of course.)

I guess I trying to figure out if I need to get a Blu Ray burner to get the benefit of the HDV camera when played on my son's 1080i TV.

You don't necessarily need a Blu-Ray burner but you need a Blu-Ray/HDV player (dependant on formay) to play the high definition DVD.

Encore would only let me put 1.5 hours of HDV video on a 25gb Blu-Ray disc at highest quality.

Thanks Paul. That will be up to him to get a HD player.
