How many gigabytes would a 60 minute video be?

when captured.... In full- hi-res HDV?


Sorry for a lack of a better way to put it....

10-11 GBytes per hour for M2T compressed HDV.
30-40 GBytes per hour for CineForm compressed HDV.
234 GBytes per hour for uncompressed 1440x1080 4:2:0 HDV.

Are you talking about HD video or HDV? HDV is a 25Mb/s format just like DV is. That's why it can use the same tapes, so wouldn't it be the same as DV? I'm asking because I don't know from first hand experience with HDV but from what I do know, it's just compressed differently before it's laid on tape in the camera, right? You can't fit more than 25 Mb/s on any DV tape.

Yes. HDV and DV compressed formats are around 10-11 GBytes per hour. Note: the HDV vs HD distinction is vague at best. Really anything that is higher spatial resolution than SD is HD. HDV simply a subset of HD.

Aaaahh, thanks for the clarification. I was getting a little worried for a second there, excited for the prospects, but worried about the massive storage.

People with older 20 to 80Gig hardrives are definitely going to have problems.

As most new hard drives are high enough spec'd, there shouldn't be a problem as long as you can archive back to something like a DVD...

Working practice wise, I must say that the 10-11Gig per hr can very quickly expand to 20>30Gig once you done some colour corrections, edits, titles......and conversions to DVD etc, etc, but keeping an eye on what's happening should be enough. Oh, and if you use AspectHD or ConnectHD, and capture both CFHD as well as m2t you'll have an automatic size blowout of around the 40>60 gig mark.

A good size SATA RAID 0 array dedicated to your HD files is very handy, and quite affordable these days!!!
