Frage von mcstudios:
Hi everybody!
I turn for some time live video for different acts, and now, the opportunity arose for an entire festival to turn.
Yet I have 2 questions:
Video Switcher This time the organizers have s.Start synonymous video board, and if I did turn with 5 cameras s.der main stage, I am now, of course, synonymous for supplying this video boards in charge.
That is: How do you get a picture mixer, you usually need a specialist or can make an educated Mediengestalter Picture / sound synonymous to happen? How do you usually connects to the cameras? Firewire unlikely, right? I mean: What kind of camera I use?
About Links and Tips, especially of people with experience in this area, I would be very grateful!
Intercom / radio Already seehr often the term "Intercom has dropped" ... but how does it work? What do I need to enable 4 camera people to communicate with the Directing? Where do I get as Headset + intercom for the Directing?
Finally, a general question:
All must be synonymous with one man shot s.der (FOH) function is about 40m cable length for the video signal and corresponding distances for the radio!? Where you can save costs in order to waive any of the headset for Total-Kamermann ... SIDN clear instructions before each tape ;-)
I very much hope can give me tips jmd!

Hello
So I do not know what you have for cameras, but is actually the most common transmission via SD-SDI, HD-SDI or composite, of course, get transferred synonymous via HDMI or component, that crops up on it and have your cameras s.welche outputs which inputs your mixer.
The first three signals are transmitted normally through BNC cables that are at such length (we sinds partially 200m and more) to have relatively favorable.
Interkom is survival without geht's definitely not!
We have always s.welche radios is used to connect headsets, are available at stations do not synonymous finished Wired systems but the price for such is indeed the other side of good and evil.
can make an educated Mediengestalter Picture / sound synonymous to happen? I would say yes. The handling of the desk to desk's just different but otherwise ...
How do you get a vision mixer Sowas gibts actually in most camera distributors

Simon
Antwort von TomStg:
Essential to the success with the Video Mixer is a timebase corrector for all connected cameras - this is either built into the vision mixer or it must be switched separately.
When I dropped the wired intercom solutions better, because they are interference-free than the spark gaps - especially if the picture direction must be accommodated in separate rooms. Hanging off of the local conditions. With a used headphone splitter / amplifier can start a lot. In contrast, it sees it, if the cams used to be not stationary, but movable, eg, steady-cam on the concert stage. Since we use a normal wireless headphones as the intercom. For the Picture Transfer You will need a proper spark gap. However, these costs ... Alternatively, you make it synonymous with a cable. Are then limited but strong in mobility, and you need an assistant who runs the cable.
Otherwise, that what Simon has written. Without intercom so you can not solve a problem! Also you must s.der picture someone sitting director, who is familiar with camera settings and for a long time to focus simultaneously on 5 cameras. That is a task that is heavily underestimated in general.

Thanks for your help! which has already helped very much! :)
An even ask TomStg @
you write ....
Essential to the success with the Video Mixer is a timebase corrector for all connected cameras - this is either built into the vision mixer or it must be switched separately. ... I did not know what a Time Base Corrector exactly makes me a little now and have been smart. Is interesting not only for Sampling signals?
My present constellation (after a few phone calls with distributors of Event / Media Technology) looks like this:
4 times Canon 5D -> HDMI output -> HDMI to HD-SDI adapter -> cable to video mixer -> HD-SDI video board again Because I need a Time Base Corrector, or should I do my best to find the mixer with a built ... or is irrelevant in digital HD formats?
Many many thanks!

Antwort von Somin:
Should work well, the whole constellation, with the 5D of course not unbediengt the ideal camera for something like this is.

@ mcstudios
You want to make a live concert recording with 4x Canon 5D??
This is not only not perfect, but quite wrong!
You need the TBC only cams, the analog output.

Antwort von mcstudios:
which argues against the 5D? stand straight aufm hose?
Several had already often in the inset, only just regie without canvas and live video.
So if its the lack of an auto-focus means: the camera people are pretty tried and have become synonymous live no more problems with it!
speicherplatz problem? Everyone has multiple SD cards, the plug of ejmd. otherwise be read again and again ... the cameras change the cards .... just like they put new clips added .... start as is always min of signal. 3 cameras there.
But let me be happy to disabuse ... that would have occurred to me now, versus the usual arguments ....
here, then, so I can swerve back ;-)

Antwort von TomStg:
Synonymous There is nothing wrong if you make your toast with an iron - crisp and warm are they synonymous.
Synonymous and it speaks very little against your cameras if they have fallen from the truck. But in every other case is ne Videocam the most economical means to live qualitiv ordinary film-like images.

Antwort von mcstudios:
.... I have now misunderstood? There is a serious problem with the Eos from your experience? 4 are the same eos nunmal available: through the camera people who possess these "private".
what would you prefer:
hdv camcorders or eos 5d mkII?
schonmal anyway thanks for the many tips!

... which argues against the 5D? ... everyone has multiple plug SDHC cards ... that would have occurred to me now, versus the usual argument ... I would counter-argument (still think the limitation of only twelve minutes of recording time s.Stück in HD, right?), Which is reserved for recording in the camera rather disturbing. To the problem of possible overheating occurs when synonymous lower than the 7D, but a gradual deterioration in picture or even a heat-related shutdown of the camera after one or two hours, I would not want to risk it. A real camcorder not just the very lowest category is clearly the better choice. And give your camera crew, when do they have to turn it with a 5D, at least CF cards - with SDHC does not come to be so much ;-)
Antwort von newsart:
Vision mixer to your question: It is less a technical matter, as one of experience. Sure you can technically any reasonably familiar with the matter, people put her desk. It's only about "push buttons" to. In practice, this is primarily a design task. If you have any additional director who is bildmischer the "boss" in the team. He must give each camera features instructions for the photographer. Constantly on the intercom announce (that's you've got it! Work) and with great foresight. The "switch" of the cameras can really everyone. A live cut, however, the synonymous possibilities of your exploits many camera positions, is purely a matter of experience. I may have mixed in more than 100 concerts and festivals. Mobile Director, OB van, recording, live broadcast, Wall, etc. I would rather make 5 "running up" s.The cameras, when taking an inexperienced mixer. That is the bottleneck, and it controls your team. Last but not least, synonymous fold should zusamenspiel between image and sound control director - which is on the Live Wall no preference. And most important: Think of your choice in the signaling pathways of the cameras, the mixer, etc. s.ein possible delay. Only 1.5 seconds delay can make on a live audience, the Wall Kirr! Incidentally, we have learned from experience that it is usually cheaper s.end is to rent a slightly older OB truck, when not working with camera moves. For the wall so you do not need HD recording. For questions call me.
