Speed capture?

Hi Guys,
I had an argue and I wanted to ask more advanced users
Is it possible to capture not in real time from miniDV?
If Yes - with what device(s)?
If not - why not, what's the problem?
10x in advance.

10x man I was sure that there were such devices.
U were very helpfull...
Can I be a little insolent and ask what interface is used by Sony?
I see that FireWire 800 is almost 800Mbit/s. It shoulde be enough for 2xSpeed.
I red a little in Wikipedia so there it's said: miniDV is 25 Mbit/s. That means that FireWare 400 should be capable of transmitting 16xSpeed in my calculations...Am I wrong?

(I'll get a bottle of Vodka from the argue).

I gotta ask to expand my internet vocabulary.....what does 10x mean? Im guessing it is somehow thanks?

Oh ok...I knew that 10x, I just came across in his posts as if it was some new jargon for thanks or something.

I guess you got an answer. The limitation is with the source most of the time. A DV camcorder is set at 1:1 transfer speed. You can purchase for a fairly high price a playback deck that can transfer faster from the DV tape. DV is 3.6 MBytes/sec, if I recall properly. That's a fair amount of data per second, even at 1:1.

Just to be clear, a DV to computer is a data transfer. Not really the same as a capture from a analog source that is converted to a digital format. Think of it like copying a file from one drive to another. One big difference is that DV transfers don't have error correction like most data transfers internal to a computer.

Maybe when DV camcorders switch completely to hard drives or solid state drives, you may get faster transfer.

It has nothing to do with Firewire as far as bandwidth. Firewire 400 would be good for 10x+ if that was all there was to it.

The data comes from a tape that will only play at 1x for consumer decks. Pro decks can speed the deck speed to about 3x in fast transfer mode but the cost to do this is maybe 10x. Tougher pro tapes are also needed for use on these transports. Consumer MiniDV tape will stretch under rough handling. DVCPro decks and camcorders run over $15,000 ea.

The Sony XDCAM ($27,500) records DV to a BluRay DVD. The Bluray DVD transport can be accessed as a network node under network control protocol and transfer can proceed to the speed of the DVD drive. I think this is ~72Mb/s or ~3x for BluRay.

The Panasonic HDX-200 can use flash media P2 cards for DV storage and also will connect as a network node. It will transfer to the limits of the flash media.


PS: You can buy a Firestore FS4 for your current DV camcorder and capture to a hard drive. This drive can also be accessed from the computer as an external hard drive under IEEE-1394 and can transfer >240Mb/s or ~ 8-12x.
