Live Streaming with EX1

[Craig Seeman]

EX1 in HDV compatible mode over firewire.
If you have MacBook Pro with Express port, Matrox MXO2-LE from HD-SDI can work and it’s what I use. I have a Livestream Premium account and I use the above with Telestream Wirecast (see COW Wirecast forum).

I’m not sure if Livestream will recognize HDV or MXO2 directly though. You can try with their free Procaster app though.

Thanks Craig,

I finally got it by connecting firewire 9 pin – 4 pin to the mac and using Telestream Wirecast to broadcast it onto my Livestream channel on facebook. Very exciting stuff!

The only problem now is that there is a huge delay in the stream, (3 minutes) and it doesn’t flow nicely. There’s a lot of stopping and starting. The viewer in Telestream is fine though, it’s just the picture in Livestream.

Is there any settings I can adjust to get a smoother icture with less delay?

Thanks,

Colin

I use my EX1 to Microsoft Live Meeting using the 4 pin Firewire out to 4 pin firewire in with a PCI card to my PC laptop. I bring the audio in using the headphone out to the mic in on the PC. The quality is mediocre at best but the delay is less than a second. I would think 3 minutes is unacceptable. It could be a internet problem that is causing the delay. Do you have sound also?

[Craig Seeman]

The three minute delay sounds like it might be internet or server related.
What are your encoder settings (frame size and data rate) in Wirecast?

Hi Guys,

Thanks for you help thus far and happy new year! I was on hiatus for a while but I’m back working on the project.

Lowering the data rate and frame rate improved the stream speed dramitically. I haven’t concentrated on sound just yet, picture is the priority for now!

So far I’ve just tested one EX-1 plugged directly into a macbook with firewire which has worked. I’d like to upgrade to 2/3 EX-1s for a shoot. As I said this is new territory for me but I’ve figured that using 2 EX-1’s (either through a vision mixer into a macbook or through 2 different 800 firewire ports into macbook). The signal would be inputted into Telestream and broadcast that way?

What are the benifits of using the Matrox MX02?

Also concerning internet speed, what would the best portable connection be to do the job to livestream on facebook to say 1,000 viwers?

This is the specs for my current mobile broadband
Deevice speed: 14.4 Mbps
Download allowance: 15GB

Thanks,

Colin
