While many of you may be using the TriCaster Mini
as a portable TV production studio in your business, school or in remote locations where you can easily access AC power and a network connection, there are times where you need to be able to work in a really remote location and record your program or uplink it to the web directly from your vehicle.
Since I’m working a lot in the UAS (Unmanned Aerial Systems) or “drone” industry as a commercial operator and trainer, I’m often asked how one might capitalize on some of the newest streaming HD capabilities of today’s prosumer drones. As one of my friends and colleagues in the industry, Eric Cheng, formerly with DJI accomplished in 2015 by taking a couple of their Inspire 1 drones to the volcano in Iceland and were able to live stream an HD video signal to ABC’s Good Morning America live broadcast
but that required a great deal of hardware and technology.
But not everyone needs to send a satellite feed to a major TV network to accomplish a similar style live broadcast production in the field. With a simple small production setup out of the back of your van or SUV, you can put together a modest yet professional system that can accommodate up to 6 cameras and or HDMI video feeds from your drone’s controller.
Basic Remote Production Setup
We first experimented with a remote studio setup in 2014 for a live broadcast drone workshop on CreativeLive
where a TriCaster was used in the tent and the multi-cam production was fed to it, along with the FPV feeds through converter boxes. It was a crude setup, but it mostly worked.
With today’s advanced technology of the TriCaster Mini
and HDMI capable cameras and devices, the setup is much more streamlined and practical to use with prep time taking only minutes.
All you will need to start with a simple setup to capture and record a program to your TriCaster Mini in a vehicle with an AC inverter installed that is accessible to your remote shooting location where you can plug in your equipment and set up your production from there. This must be a hard-installed inverter of at least 400W and not one of those 100W inverters you plug into your auto adapter/cigarette lighter. In my tests, I ran the TriCaster Mini, LCD monitor and the power brick for my Lenovo P70 portable workstation all off the single outlet for over 2 hours on just the battery in my Toyota FJ alone and didn’t have to run the vehicle at all (your mileage may vary, of course).
You can also use a backup power supply for a short production, such as the 400W Anker PowerHouse
120,000mAh which is a silent alternative to running a portable power generator – especially if you’re doing any sound recording or interviews.
You may also be at a location that actually has power available to you with a long extension cord, such as at a park or near a barn that will provide you with what you need all day.
With the TriCaster Mini
and an LCD monitor powered by your desired source, you can input up to 6 HDMI devices, including camcorders, DSLRs, GoPros and even the live FPV (First Person View) video feed off your drone’s receiver or radio controller.
You can then mix and record your program direct to disk on your TriCaster Mini and then transfer it to the Web later or use one of many different live broadcast solutions such as a Teradek or LiveU through a 4G packet (I’ll get into that in more detail in a bit).
Since my current test included only one camera on a tripod and one drone in the air (as I was by myself at the time) I only had two inputs active. I was using the second controller for the DJI Inspire 1 that is meant to control the camera and gimbal on the drone by a second operator, but you can set it up in a static position within reach of the TriCaster Mini as long as the HDMI cable can reach it and you have a clear view from the radio controller to the drone. Then you can stand anywhere else – even hundreds of feet away to pilot the drone separately without having to be “tied” to the production truck.
One of my colleagues, Mike Fortin with CineDrones.com does regular TV production aerial shots with an Inspire 1 and uses an extended stand to mount his controller too with an external battery and it can feed the HDMI signal for hours without anyone ever having to touch the device.
The two inputs were then manually “switched” to record video to the TriCaster Mini
to test the setup and it worked perfectly. The only issues were transmission signal “skip” when the drone went close to the out of range fringe around a mile out over the bay and the signal was weaker, but in a live production, that’s to be expected at times.
I purposely left the OSD (On Screen Data) overlay enabled from the drone’s FPV video feed to provide live data for altitude, distance and direction just for my tests, but normally you’d want all camera data disabled on output to provide a clean video image in your production or broadcast. Here you can see both monitors and the captured production from the TriCaster Mini screens.
Broadcasting Your Live Production
As I mentioned earlier, there are a few different options you may have to send your live broadcast production online from your remote location.
For those that want/need expertise and management of cellular networks and bonding, companies such as LiveU
, Mushroom Networks
, and TVU
provide both hardware and services. You network these devices to the TriCaster and they send the stream out over the cellular grid.
For those that want to manage their own remote network solution, there are routers that can accept connection to WIMAX and WIFI hotspots. Peplink
is a company that makes such devices. The main thing to consider here is that you need to staff personnel that really knows and understands the technology.
None of these options are cheap, however. There may be a chance that you could utilize a single 4G or LTE modem directly from the TriCaster but if you’re counting on an uninterrupted live broadcast, then it’s possible it might be interrupted if a network change is required.
A simpler solution – although maybe not economical for your budget is a system like the Mushroom Networks Streamer PRO
which will allow you to take the signal directly from the TriCaster Mini and sends it via an array of 4G modems to your cloud-based data center or directly to an open stream online.
It will be interesting to see this technology continue to advance in connectivity speeds, lower costs and ease of setup & operation.
