Torby, I think you read the question correctly. How much space does a 60 min HDV tape take up when captured.

HDV uses the same bitrate as DV, so theoretically the file sizes will be the same. However, if you use an intermediary codec then the file size will be bigger.

To second what was said before me on this thread, just about the same as DV.
From this site. http://www.hdvinfo.net/ What is HDV? HDV is a "consumer high-definition video format" proposed by a consortium of manufacturers, the core of which is composed by JVC, Sony, Canon and Sharp. These companies proposed the basic format specifications in July of 2003, and the formal announcement of the format came in a press release from the HDV consortium on 30 September 2003. HDV is native 16:9 with supported frame rates of 60i (frames-per-second interlaced), 30p (progressive), 50i, and 25p. All HDV variants record to existing standard DV format digital video cassettes, the most popular form factor of which is the Mini-DV shell. The transport stream interface conforms to IEEE 1394 (FireWire).
HDV1 (from JVC) is a 19 megabit-per-second MPEG-2 transport stream with a resolution of 1280 pixels wide by 720 pixels tall. HDV2 (from Sony and Canon) is a 25 megabit-per-second MPEG-2 transport stream with a resolution of 1920 pixels wide by 1080 pixels tall.

oooops just re read the question...thats probably not what you asked at all...I actually thought you meant what the contents of a 60 min tape equates to when its captured....sorry... |
not what he meant exactly but I think it's the number he NEEDS to know.
I capture HDV. Don't have exact numbers to hand but a tape full of HDV in it's 'raw' format (m2t) is about the same as SD AVI. However, as it's basically MPEG2 video it's not overly editable. After converting this to a more edittable format (AVI again) it pushes up to 50-60Gb per hour.
