# 4x DVD+R discs?

Discussion in 'DVD Video' started by JethroUK©, Apr 12, 2004.

how does '4x' relate to DVD recorders?

i realise that 4x indicates the disc can be burned at 4 x normal speed (but
what's normal in a dvd-r)

but my dvdr uses 1, 2, 2+, 3, 4, 6 hour recording compression (doesn't
indicate the actual burning speed, but i would like to burn these at 2 hour
compression)

so how does these 2 methods equate?

Basically, it doesn't - it's only relevant if you have a PC DVD
writer.

With a standalone DVD recorder, you're recording video in real time,
so you never need to burn outside the normal (1x) speed range.

Normal is up to (roughly) 10 megabits per second, which equates to
about an hour of video per disc.

1 hour = 1x
2 hours = 0.5x
3 hours = 0.33x

.... you get the idea.
