Hello,
I zuzulegen before, mír the mixer of Videonics MX-Pro DV.
Everywhere I read that the firewire cable max. 4.5 meters should be at a transmission of 400 Mbps. From 4.5 m to be dei Data transfer up to 200 Mbit / sec. . Switch As far as I know, is a video into the calculator with 3.6 MB sec transfer /.
My question really is, I can do with two DV camcorders a live mixing on a Firewire cable, which is about 20 meters long? Suffers from the quality?
I was recording it on a Datavideo DN-100 with 120 GB FP, then reaches out to write a speed?
I have made previously tried everything on your PC and, subsequently recorded synchronously to mix so that it looks as if it Währe Live gememsicht. Unfortunately, it is time-sher. Therefore I would like to get a piece of the device Chaten.
I'm happy about any info!
Thanks
Özkan

The cable length does not influence the transmission rate directly. But the inherent resistance of the cable is greater with increasing length and there will come no more to s.anderen end. They say in general exceed 10 m. It certainly is synonymous with the quality or the cross section of the pipe. Can not you try it once with a camera and a PC?

Hello,
I have the Mx-1 can only analog. In our department we have had for a few months of this Mx-Pro DV. I have tested it a bit and am very disappointed. Especially when you mix video signals via firewire like. The following problem occurred: The Fiwi input was qualitatively worse than the analog CVBS input. And not long s.der Camera, still s.den cables or cable lengths. We have since conducted several tests, synonymous terms that processing times (Fiwi video is approximately 1 / 4 sec after the analog video later) turn. So you can not mix analogue and digital sources, because each source has no delay option. One can only delay the sound.
I told you once attached a Picture to see where you can, the analog video (right) and digital video / Fiwi (left) processes.
I want to talk to you but not the mixer, you should definitely decide for yourself whether you buy it. I would not buy it myself. I still work as long as analog, and I might eventually upgrade to SDI can, however, DV and Fiwi in my eyes is just what ect for the post production with PC / Avid.

Thanks for the quick response.
Unfortunately I have not bought any cables in the track to try it out. If I hear positve here, I wanted to make investment dei.
I would stretch eingeltlich, when at a length of 20 m, the data throughput of 3.6 Mbytes / sec. is given. Then it will probably be no picture when record losses, right?
The question I place synonymous to me is that the signal strength for a cable length (throughput of 3.6 Mbytes / sec.) Of 20 m Firewire cable as strong as in a cable is 4.5 m Firewire?
If this is gewähleistet, there should be no Bildverlsute.
Any answer is welcome!
Thanks

Hello Lutz,
Thank you also! Even for the Picture.
I understand from your answer the following:
You've made a mixture of DV - and analog sources? Because of the image lag, or was it both DV device as input sources?
How is the quality when mixed analog sources only?
I had never before, to buy MX-1. Then I stumbled on the MX Pro DV. Since I recorded on the PC editing and uploading, it would have been a good choice.
If there are no differences in analog mixing between the Mx-1 and MX, Pro DV would be the view from your investments OK?
Thanks again.

Hello,
The mix is a good SonyminiDV camera (3CCD), which was once on Fiwi and then connected via RCA. ALso, an input digital and one analog input. I have the analog input simply do not like this noise and then krizzeln and significantly darker.
The quality of the mixing of analog signals is basically the same as in the Mx-1. Only the handling is slightly better in terms of a few specific functions.
As far as the cable lengths, you can make good use of analogy to 40m, I have been synonymous with 40m Fiwi seen, but do not know how well it works then. This year, my Department but synonymous 40m buy these cables, maybe I will know what.
One advantage of analog cables from Fiwi is of course the price.
I work with my Mx-1 for 6 years, but I have s.dem synonymous made some improvements. I now accept, however, synonymous everything on the same s.PC. For this I use an AD converter (eg Terratec Cameo Convert or similar).
If you have further questions you can contact me directly synonymous anmailen happy, I still have more results of the mixer test, which I can publish but not great. My email is in profile.
Best wishes
