How to load a Backpack

By December 14th, 2011 Field usage No Comments

You probably came across this page, because you were looking for some of these fancy video transmission backpacks. These backpacks are a new trend in mobile TV production and sold by different vendors. Mbcast.com in contrast does not sell backpacks: We simply provide a software for standard notebook computers, so that you can build your own transmission backpack. Here is a small tutorial on how to use the Mobile Broadcast System in a backpack!

First, set up the system with the laptop, the internet connection and the camera as usual.

Make sure the energy settings of your laptop decline shut down, when the monitor is closed. The following link gives further instructions on how to do this: http://www.howtogeek.com/howto/25230/beginner-geek-change-what-windows-does-when-you-shut-your-laptops-lid/

The easiest way to connect a camera is using FireWire, because it is available on many laptops. But one drawback in field usage is, that FireWire connectors can’t be locked like SDI or XLR plugs. So we needed to find another way to add some stability to the cable connection.  Using angle plugs instead of straight connectors, and fixing with a strap-on band turned out to be a decent solution.

Put the system in a backpack and make sure the ventilation outlets of the laptop are not blocked.

Finally, you can start shooting with the transmission unit on your back.


Mobile Broadcast vs. FTP server solutions

By December 5th, 2011 Field usage No Comments

Mobile Broadcast represents way more than a server solution. Besides the server, there is also the client software, which makes journalistic broadcasting very mobile and time efficient. Once you have shot your footage and caught everything in your camera, the time-precious process of transferring the material to the TV channel starts.

When you finished the rough cut, with common ftp solutions you have to encode and then transfer the material, which are two time consuming steps. This process takes twice as long as with the Mobile Broadcast software. There is a plug-in for Adobe Premiere Pro and Grassvalley Edius, which encodes and transfers the footage at the same time. The graphic bar of the encoding runs slightly ahead of the transfer bar.

Another advantage of Mobile Broadcast to any ftp solution is that the transfer of the footage can be resumed at any time. Not a single frame gets lost, when the internet connection breaks down. It automatically resumes the transfer from the very last frame, once the connection is re-established.

Recently released by Mobile Broadcast was another software application, the file transfer application. With this application you only have to select clips from the camera’s memory card and directly transfer the files. Also a small editing is possible, as you can restrict the length of the clips. This software saves a lot of time and is the absolute last minute solution for ENG crews.
