Start broadcasting like a pro! In this section, you will find links and advices about the best equipment and setup, such as suggested by the Mogulus producers.
Every webcam should do the job! Whether you have an in built camera or an external webcam, plug it into your computer and select the input in your videosources. Be careful: IP camera's are not supported by Flash and do not work in the Mogulus studio!
The webcams we suggest:
With Mogulus, you can also use DV-cameras.
- Native on Macs through Firewire.
- On windows you need a Firewire Ie1394 input on your pc. you can get add on cards from providers like canopus http://www.canopus.com/
Some laptops like Sony have it as standard.
- Plug it , make sure your computer can see it - try to open for example an editing software.
- Go in the mogulus studio , select DV in the video sources and here you go
- Make sure you select the correct audio input...
Please check with your camera provider if your device is Flash supported!
Connect only one camera per computer!
If you wish to use multiple camera's, plug them into different computers and login to your studio on each computer. You can then switch easily from one camera to another.

We unfortunately don't provide simple live audio streaming, however, one of our producers Moohead (http://www.mogulus.com/mooheadradio) has a radio show and has given us his recipe for sound streaming:
Here is the entire audio chain:
Behringer B-1 Mic plugged via XLR connector to a Mackie 1402 VLZ Pro Mixer. Mixer Tape Out to line in of desktop (this is for the audio stream and audio archive of the show)
Phone Calls"': We use a Comrex Stac 6 phone interface mated with 2 Vonage IP phone lines plus a transparent 877 number from Vonage. This allows our viewers to call in toll free! We use a standard handset phone that hooks into the Stac 6 handset hardware. I answer calls as the lines light up. The Stac 6 controls caller levels.
Studio cohost: We use 2 Comrex Access units. These devices connect my co-host and I together through the internet WITHOUT TYING UP A PHONE LINE! The Comrex Access connects to a static IP port in my cable modem. Even though we are 2000 miles apart, we sound like we are in the studio together. The Comrex Access utilizes low latency audio codecs so we have virtually no lag, as well as high fidelity. This is important because it enables us to send one high quality audio signal to the Mogulus studio, containing both of us, as well as our phone callers.
Mogulus Studio: Next we run from the Main Out of our Mackie Console to the Line In of a laptop that is ethernet connected to my cable modem. We have a 15Mbps download, 2Mbps upload broadband connection. This sends all of our show audio to the Mogulus Studio, so everyone can be heard. Finally, we connect the laptop USB out to our Mackie Channel strip, using a USB sound card. This enables viewers to hear all audio from the videos we pull from the internet and create ourselves. All we do is "un-mute" the channel whenever we run a video that originates from the Mogulus Studio.
Video: I use a Canon GL1 3 CCD camera plugged into the laptop via firewire. This camera can be manually adjusted for low light performance. My co-host uses a standard high end webcam!
The end result is a program with sound quality that equals FM radio at its best.
You can stream your desktop, a videogame or a movie into your Mogulus studio. To do so, you need a capturing software such as:
webcammax for PC
or camtwist for Mac
Download the application, open it and select your frame. The software will appear in your video sources inside the studio.
Check out our demo video below.
Chroma Key software
According to Wikipedia:
Chroma key: Chroma key is a technique for mixing two images together, in which a color (or a small color range) from one image is removed (or made transparent), revealing another image behind it. This technique is also referred to as color keying, colour-separation overlay (CSO; primarily by the BBC), greenscreen, and bluescreen. It is commonly used for weather forecast broadcasts, wherein the presenter appears to be standing in front of a large map, but in the studio it is actually a large blue or green background.The meteorologist stands in front of a bluescreen, and then different weather maps are added on those parts in the image where the color is blue. If the meteorologist himself wears blue clothes, his clothes will become replaced with the background video. This also works for greenscreens, since blue and green are considered the colors least like skin tone.(...)
Chroma Key Software has the advantage of being cheap but does not enable you to stream live while performing chroma key effects. You will need to pre record your content and upload it to your Mogulus studio.
Here are a some links:
Real time effects!
This software is an amazing tool but requires lots of practice, time and knowledge! http://www.troikatronix.com/isadora.html
Chroma Key hardware
Chroma Key hardware enables you to make a realtime green screen effect.
Check out the shows of one our producers, Sarah Meyers, who is live on Mogulus every Thursday at 3 P.M. directly from the Mogulus studio in SOHO, New York.
This is the device we use in our studio.
On Mogulus, you can also stream analog video from your TV or other sources! Therefore you will need 'capture cards' like TV cards.
There are external and internal ones.
Those cards are made for PC's and will be recognized by your Mogulus studio in the video sources.
Those Capture Cards come with USB output and are useful if you are working on a Mac or a laptop.
Once installed, they will be selectable inside the Mogulus studio in the video sources.

They take analog video into your computer.
How to set up multiple cameras
You wish to stream from multiple cameras?
We suggest you have one camera per computer. So, if you want to do a show, filming from three different angles, you will need three different computers.
Log into your studio on the three computers and select the correct input on each one.
Now, you can mix the cameras live from one station, by selecting them in the left tab (sources) in the Broadcast live section.
If you wish to mix audio and video, you will need to have an external mixer!
