There was a short film shooting last semester. We help each other film, but New York has a small place. Finding a large place costs a lot of money, and if a small place is the place we are shooting we have to hide behind the camera or where camera does not shoot. Other than the cameraman, if you want to see what is currently being filmed, you will be wired to watch the monitor at video village set up. If there is no moving camera, the filming proceeds, but there are few problems, but the video village needs to be moved when changing the location of the camera and filming in a different angle. What I was able to do was to see the screen through the app from the camera, but it was often cut off even with just one wall. So I bought a video transmission system. Being able to see it wirelessly is a very convenient shooting. It's really beneficial that you can connect to the video village and watch it, and the 1st AC can shoot without moving with Wireless Follow Focus.
Receiver - The receiver can be connected to the monitor. The monitor connection may be an SDI cable or an HDMI cable. Mars400S Pro supports both. If you look at a transceiver that's one level lower than this, there's often only SDI Cable.
SDI port is on the side. Many of the equipment in the movie set uses SDI cable. So SDI port is absolutely necessary. Cinema cameras have no HDMI port out, only SDI port. This transceiver supports both, so there is no problem.
On the back, there is an HDMI port, USB C, VDC 2.1, and a battery-coupled space. HDMI port is the part that connects to the monitor, so you can check the monitor and the connection cable and use HDMI or SDI port on the side. And you can give power using batteries or you can give power through USB C port. And VDC 2.1 can also give you power. There are three armies that can connect the power. It is better to find and connect the most convenient one that can be used according to the situation. And the two gold connection terminals above are where the antenna is attached.
Transmitter can be connected to the camera. The receiver has the same design, so it can be easily distinguished by the color of hot shoe. Red is a transmitter, blue is a receiver. And the back has all the connecting terminals just like the receiver.
Five antennas were included. You can only hang four, but one is an extra. I think the extra means that the antenna can be easily broken. And you can buy different antenna and use it. There are antennas that are smaller and less likely to break.
You can use two receivers for one transmitter, or you can only purchase additional receivers. Or you can use the app to watch it on your iPad. There is a fixed number to receive, so I recommend you to check how to set it up. During the last shoot, the receiver SDI port was connected to the video village monitor, the HDMI port was connected to the 1st AC monitor, and the director used the iPad app to check the screen during the shoot. This is the best setting I found as of now.
This bag is not included when purchasing the MARS400S Pro. You need to purchase it separately, and you can carry transceivers, antennas, and SDI cables or Power cables. Video transceivers are products that will be used more and more as filming increases. I think this product is the best cost-effectiveness. Teradek products are better, but the price is almost 20 times higher. Since Teradek has less delay and can be far away, it is expected that I will continue to use Hollyland than Teradek unless I has a production company later.
