Capturing via component input: a question at DVinfo.net

Stupid question of the week: if I capture HDV footage via component input, will it take up more disk space than capturing via firewire? The reason I ask is because component is technically "uncompressed"... if it's HDV footage, wouldn't that suddenly take up more hard drive space?

The reason I ask: I'm getting the JVC HDV deck and it can only play back 1080i through component output. Therefore I need to know the best way to handle 1080i when I use it (my main camera shoots 720p).

Short answer is yes, it should. HDV is 25 mbit/sec or less. Depending on what codec you digitize to when using component inputs on your capture card, that rate will probably be a good bit higher if you digitize full frame rate HD video. The right choice of codec will depend on your capture card and workflow.
