K, I'd suggest the DV codec, usually in an AVI container.
It's great for video editing -- behaving like uncompressed AVI. Bitrate is usually 30mbps (also I've seen 25mbps as well, maybe it's for 30 and 25fps respectively?).
Anyway, I can recommend Panasonic DV Codec to you, or the built in version from ffdShow (if it works, that is).
Let's do a bit of calculation:
Code:
12h * 60m / h * 60s / m = 43200s
43200s * 30mbit / s = 1296000mbit
1296000mbit / 8bit = 162000MB
162000MB / 1024MB / GB = 158,2 GB
There you go! The 160GB version should be enough, BUT: Unfortunately they mean 160
decimal GB, which is only 149GB - if I'm not mistaken... divided 160 trillion by (1024 ^ 3).
Anyway, rule of thumb: Preserve 14 GB for each hour of video material that you want to capture / edit later on (13.2GB actually needed for one h @ 30mbps)
