We have upgraded the C3 Lausanne Video setup. A good part of 2014 was deciding what to use, and how to design it to have a very efficient for our usage.

After many researches and comparisons, we went for a Blackmagic Atem 2M/E 4k Switcher.

The main features of the switcher are:

  • 20 SDI Input (one input can should be able to be switched to HDMI, however, we are experiencing image freeze issues on this input, and will change the computer to be able to use  only SDI on the switcher)
  • 6 AUX output which can be directly changed on the front panel of the switcher (with a dedicated AUX preview)

The Switcher is controlled via a M/E 1 Control panel. The ME/2 would have been too big to be easily transportable and for our usage it works well enough with the quick switch function ME1 to ME2.

The switcher is mounted in a customized and fully preconnected flight case with all the rest of the media equipment. It allows a very fast setup with minimum possible error. 

The setup is (starting from the top):

Flight case views (Front and back)

Closed flight case and back panel view

So far it has been brilliant to work with this switcher.

The only down side, has been the HDMI input instability which we are planning to change very soon. The idea is to output the computer via Thunderbolt to a Blackmagic Ultra Studio MiniMonitor in order to connect on the siwtcher using one of the SDI. (see UPDATE below)


And to finish a view during a live production:



UPDATE (21.01.2015): We are now connecting the computer (MacBook Pro) via a Blackmagic HDMI to SDI converter and all the stability issue have been fixed. 

UPDATE (18.10.2015): Confirming above update. no issues anyore with the computer over SDI.

One thing that we noticed and could be also usefull to some users with issues. For some tests, we had the HyperdeckShuttle on top of the ATEM Switcher. When starting or stoping a recording on the SSD, the ATEM froze on some of the inputs and had to be restarted. This also happened twice when we left one of the wireless Intercom (Altair WBP-202) on top of the ATEM switcher. We now do not leave anything wireless of creating magnetic interferences on top of the switcher and since it's all good.

We have finally purchased an intercom system for C3L.

After much research, we decided to go for an Altair WBS-202 system. The system allows wireless and wired Intercom  and has 2 channels available.

So far after a few weeks using it I have to say I am highly impressed and convinced by our choice.

Finally the video setup is up and running. Hopefully all our struggles can be useful for other users who read this poste. I will try to summarize the main findings below. For the description of all the tests, refer to the previous post.

The new set up is now as described in the below schematic:


The solution to link the Panasonic AW-HS50E mixer to the Sanyo PLV-WF10 projector was in the end to use a Blackmagic SDI to Analog Mini converter.

For the history, the different tested setup were:

Currently working on a new HD/SD video setup for C3 Lausanne.

The plan is to have everything (excepted the projector) in a flight case to allow easy transport and quick setup.

The schematic probably will be:


C3L Beaulieu schematic

The process of understanding how we should do it has not been totally straight forward as I don't know too much about HD (yet). I will try to give some details on what we learned with a short review of the different pieces of equipment.

Welcome to BigLoose.com's brand new website.

This is the 3rd version of Bigloose.com.

2002-2006 Bigloose V1 design by Platform:5

2006-2009 Bigloose V2 which took a long time to come out as I had to learn how to design it. But thanks to Joomla and the help of a few people it was launched in December 2006.

and now V3 is out! The site is still running on Joomla

V3 is also the merge of BigLoose.com and BigLoose.com/bigler my personal/familly website.  As my video work/life is always quite linked with my family life, I decided to merge the 2 websites.

Hopefully having the 2 sites merged will motivate me to keep it more up to date. The past 2 years it has only been infrequently updated.

We hope you will enjoy navigating on this web site and we hope you will come back soon.
