3 Live DV-Kameras an einen PC über Firewire anschließen...geht das?

3 live DV cameras s.einen PC connect via firewire ... is this possible?



Frage von joerg-emil:
Mai 2008

Hi,

I often filme events from three different camera angles. The subsequent loading of the images horribly steals a lot of time, synonymous are the drives of the cameras is a heavy burden.

My idea is now to the 3 DV cameras via firewire cable directly s.einen PC and the images live on the Festlplatte to play. Has anyone been in the direction of experience, or he can give me a tip.

Problems which I now see are:

- Is the data transfer rate of a firewire card with multiple inputs, or do I have for each camera with its own controller installed?

- Supports the calculator or the software (eg WinDV) three cards at all? You can start WinDV three times that I've already tried.

- How long can a firewire cable to it without the disruption to? 20m would be very useful.

- What need for computing power as a project of the calculator?

Greetings from the Rhine
Jörg-Emil

A long-running ...
Schon mal in Forum compatriots? Since there are many answers!
The problem is that there is no (I know) software, which simultaneously different FW devices can hold. (Theoretically, it would be possible.)
I myself have with Datavideo repeaters and 10m cables (! / 20m does not) good experiences over 45 m done.



Antwort von joerg-emil:

Hi David,

First thanks for the quick reply and the tip with the Datavideo repeaters. The problem of the cable length would thus be solved.

For me my problem was not the appropriate keywords in the subject and I've found is usually synonymous to the live-to-digital editing, or streaming live, that's not my concern. It seeks only the three signals simultaneously.

It will probably be sufficient, a card with 3 firewire ports to use. The project should be sure to be tested intensively by using a typical event in real time across three of camcorders will be recorded. Even a (shorter / longer) the connection should be simulated (loose contact, could happen in the pan), so that the effects (often software crashes) and their consequences (if any further demolition cascade-like images) to know.

We must thank all of the art is not synonymous forgotten that crashes the computer when all three images simultaneously and cancel the already stored sections may be destroyed. The risk can, for example, with an additional recording in the camcorder can be reduced.

16 but seems camcorder on the hard drive will be close. The reach is only about 50MByte / s average transfer rate.
Furthermore, it seems, while saving several large files on the disk to violent fragmentation come (hence the recommendation for at least 2 plates and take to the capture plate nochmal per camera to the disk.

I think the project is already difficult s.der limit of what one with 'consumer' equipment can do.
We filmed so often in our events synonymous with multiple cameras and I've already mentally with a similar setup played, but would be quite cheap and, unfortunately, not for something we have no money, so the only next to the lengthy nachcapturn.
Where's the budget would have allowed one extra synonymous NEN capture computer and tinker with the thing on stability (both mechanical as synonymous of the software) trim.

tape can be run with my camera anyway, unfortunately the only way to prevent it goes into standby.

The issue was already discussed in the forum, search it out for "SUH" and "Oldenburg."

Antwort von Johannes:

Uii I have dug up a topic on which I still synonymous same have a few questions. Well soähnlig like Urproblem this thread mine is synonymous. I have 3 cameras (all data) and a MacBookPro as synonymous another PC shuttle bus. Now I would like s.dem evening where we are equal to film a live cut make so do not need anything but a picture recorded. I know this is something Ähnliges with Adobe CS3 with gecaputerten material already do. I hope you have understood my problem, but is it synonymous with Avid or Adobe possible?



Antwort von BeSt:

Hi joerg-emil,

Canopus has for many years with his capture card, a tool
DV capture, DV takes 3x stream or in the presence of a Canopus card synonymous analog and 2x DV.

Runs with any good video-PC.

BeSt greetings



Antwort von thos-berlin:

Is that all capture cards here? Even with the external converters? There could be a card with the software quite cheaper than the pure software Suh ...

Do you have the software more information? I clicked on the Canopus Page unfortunately found nothing. (No wonder, if it is just a side dish).



Antwort von Bernd E.:

Just Google for "Canopus DV Capture" search: First hit is the manual.

Gruß Bernd E.








Antwort von thos-berlin:

If I correctly over the manual, it works only with an "alien" card, port two and three must be Canopus hardware (eg Storm) be. Or am I mistaken there?



Antwort von robbie:

What speaks against analog cable routing (eg, S-VHS), a (used?) Mixer and an A / D converter? Sure fail-safe, tested thousands of times and probably cheaper ...

Amorousness into technical challenges and the conviction, digital is always better than analog. ;-)))



Antwort von joerg-emil:

Hello again,

via an analog solution, I already thought synonymous, there is indeed from the video surveillance quite good cards. Unfortunately, the calculator generated MPEGs but not good for a clean suitable post. ...

Thank you for the lively discussion and the many ideas ... I will be my project, however, again through the mind must let go, then yes it is far more complicated and expensive than I would have wished it to me ...

Greeting of the Rhine
Jörg - Emil



Antwort von thos-berlin:

I think robbie is just misunderstood. We are not talking about the mixing of signals (which I would also make analog), but the direct recording of DV Datenstöme to later capture the tapes to save and possibly synonymous of the 60 (63) minutes duration cassette to be separated.



Antwort von Markus:

Rather than a tape after the other on capture, it could be the above info so synonymous, to the contents of two or perhaps more synonymous parallel bands on the PC. ;-)



Antwort von robbie:

oh. oops ...
naja ... and what would be against a solution of multiple fire tores, or these new things of EDIROL? * g *

http://edirol.com/images/stories/products/f1/f1_brochure.pdf

they can be synonymous all over the network remotely, by the way!



Antwort von RobS:

Someone knows if this is somewhere Porty PCs http://www.suh-edv.de/ of software, including Capture the rental there? Which I have just sent a request synonymous, but perhaps someone knows what synonymous here.
The complete package with software and calculator costs while "only" 2700 ¬, but rent is just cheaper.
