what is the storage overhead for a typical HD project?

[DVcatastrophe]

How many gig does HD video take per minute? How much space would 30 hours of HD footage potentially take to store?

Thanks.

Can you please be more specific about the term HD video? There's HDV (1 and 2), DVCPROHD, HDCAM etc. There's interlaced and progressive, 8bit mode and 10bit mode, then there is compressed and uncompressed etc.

Eg if someone works with m2t files from his HDV camcorder this stream is just 25MBps which is the same as DV. 1 hour would take 13GB of disk space. On the other side uncompressed 10Bit HD 1920 x 1080/60i in 4:2:0 will need 410GB disk space per hour.

Of course, capturing with the CanopusHQ codec is an alternative.

Sorry HDV and HDVCam, recorded on the Sony XL1S or whatever it's called.

If you work with HDV then you have two choices:

1. The data on the tape is written as *.m2t stream which has 25MBps. Those files transferred to your harddrive need the same space as DV: 13GB for one hour video. Since this is mpeg2 it's not very handy for editing.

2. With Edius you can capture from the HDV source into the CanopusHQ codec, which is an intra-frame (ideal for editing) codec with variable bitrate. Afaik the CanopusHQ codec can be used from 30MBps to 300MBps depending on your settings. Using the standard setting in Edius will give you about 75MBps, that is 34GB per hour.
