For those of you who do long videos and use Bluray, how much 1080hd video do you manage to get on a 25gb disc as in video time? Or do you know the maximum time in HD on bluray?

John,

It's mainly a matter of bitrate. The higher the bitrate, the shorter the video you can get and vice-versa.

Let say that 1h30 minutes is a reasonnable length to preserve visual quality.
