Data rates info?

For an upcoming project, the producers have asked that I give them a chart of data rates and storage requirements - to better able them to decide whether to go Varicam 24P over firewire, SDX900 @24P over firewire, or Digital Betacam over SDI uncompressed.

If anyone can help in ascertaining these numbers I would be very indebted.

I need to know;

Varicam 24P = X Mbps = X Gig Per Minute/Hour storage space
Varicam 30P = " " "
SDX900 24P = " " "
SDX900 20P = " " "
DigiBeta60i =
(uncompressed SDI out)
And just for grins

Beta SP 60i SDI uncomp. out.

DVCProHD is 100 Mbit with 60p.

24p is less cause you will use only the tagged frames.

Calculate 100/60*24 = 40Mbit per second.

I'd check with the maker of the card you would use. Kona, BMD- each have different bitrates that would determine how much space you'd need.

Try this:

Even at 8 bit the uncompressed payload of SD 4:2:2 is going to clear 100Mbps, before any timecode audio or metadata get factored in.
According to my refference:
SDI A (composite) is 143 Mbps, SDI C (4:2:2) is 270 Mbps, SDI D is 360 Mbps.

The capture card has to be recordaing at one of the SDI data rates. If it reduces it, then thats compression.

Nice charts on both pages recommmended.

Got the info I needed, thanks to all.
