1 minute of HD video equals how many Megs?

[boomshack]

Hello everyone,

New to the forum here and wanted to see if anyone knew the size in Megs of HD video (compressed and uncompressed.)

I'm specifically referring to the new Panasonic AG-HVX200 recording on the DVCPRO HD format.

Thank you very much.

a quick google search says apparently 100mbps

doing the math, it gives around 715 megabytes per minute. you're going to need a lot of space if you want to record more than a minute at a time

Thank you for your reply and for your welcome. I searched on Yahoo briefly and could not find the content.

It was my understanding that Mbps stood for Megabits per second while MBps stood for Mega Bytes per second. Which one were you referring to?

I understand that storage will be an issue, just want to be able to estimate how much storage will be needed. The camera will record on the new P2 format with onboard capacity of 2 cards (at 8GB per card each) I believe.

Thank you

Ignore my reply above...your response specified that you meant bytes not bits.

100/8x60 => 750

[anonymez]

uncas, 1 kilobyte = 1024 bytes, 1 megabyte = 1024 kilobytes, 1GB = 1024mb, etc.

AFAIK, bytes (PC) go 1024, bits (DV) go 1000

edit: when searched, all definitions of byte say 1024. but the 'online converters' seem to use 1000

It's a bloody lot no matter which divisor you use. Will require massive compression algorithms.

i just did a calculation with one of my sdtv captures, at a known bitrate in mbps. 1024 is correct...

either way, a lot of hard disk space is needed. if only 100mbps broadcast HDTV were possible

Thank you all for your replies. The camera will come equipped with 2 slots for 2 8GB P2 cards. They'll also have a 60GB external portable drive that will allow you to save info from a couple more P2 cards. I basically wanted to know if HD ran at 1GB per minute and looks like does.

Thank you all. Can't wait until this camera comes out!
