A1 uncompressed

Is it possible to capture the video-signal directly via firewire to a hard-disc, so that you've got uncompressed footage afterwards? Would it make sense?

No, the signal from firewire is already a HDV (read compressed) signal. You can use the component outputs to have an uncompressed signal. But only if it's a direct signal, if it was on tape first, even than it is compressed.
 
Firewire 800 isn't even fast enough for 1440x1080 30f or 1440x540 60i, right? Isn't that over a gigabit?

If you want live digital uncompressed output, the G1 is worth it. (and the H1 if you want interchangable lenses)
 
i read that it is possible however to get uncompressed with the A1

what does that entail?
 
so, do I have to use the component out terminal or the BNC terminal? Should both be uncompressed?! Which iption would be best to record dircetly to a harddrive?

A capture card and analog component output while directly recording (can't record to tape).
 
Actually, you can record to tape at the same time. It's only tape playback through the component output that carries the HDV compression. It's smart to roll tape at the same time anyway. I do this when recording directly to the computer.

The live camera head signal is what will give you true uncompressed, and yes, it does entail capturing to a computer. More often than not though, what you're actually needing is not to capture extremely high data rate uncompressed HD, but to compress to a cleaner intra-frame codec like CineForm or Sheer or M/PJPEG.

Truth is...at this time analog capture is only really practical in greenscreen/studio situations or larger film shoots with a dedicated video village.

Which is, on comparison, about the only places its really needed.
