It allows the pan tilt head to be controlled from the USB port of a computer. It is compatible with the motorized pan tilt tripod heads supplied in the UK by Hague Camera Supports (Bescor MP-101 and Bescor-360). I have a rather incomplete compatibility list here. Note that since 2015 many Sony cameras have a different interface, the 'Multiport', and do not support LANC. An adapter is required to connect to many newer cameras, for example the 522AV LANC-AV 10PIN CABLE ADAPTOR from Hague Camera Supports in the UK. The controller is fitted with a 2.5mm stereo jack plug for the LANC connection. The supplied software allows control of:Īll features depend on camera compatibility. and also provides control of cameras supporting the Sony LANC protocol (also called S-Link). This device gives you remote control over a Bescor pan/tilt camera power head. Anyway, 1080p is wonderfull for key.Home PanTiltLANC JMux Contact USB Pan Tilt Controller with Sony LANC (S-Link) interface Maybe it would be better to stay at 60 Herz from the input to the output. Today, i tested a red camera output (1080p 25) for live keying, and it was incredible nice !! But i did not caculate the frame delay with such an input. In my previous test, i had 150-200 msec for a 1080i 50Hertz inputĭisplaying on a 1080 60p computer screen. I prefer hdsdi than hdmi output for lowering the latency. (I know there's a similar thread about hardware for lowest latency, but I wanted to ask specifically about 1080p resolution. Is anyone else using 1080p equipment in a live production environment where latency matters? What products are you using? I need a compact camera that I can mount on a wall or a ceiling with the Bescor head. The other camera I'd like to try is the Sony HXR-NX70. I like everything else about the camera, but less of a delay would be nice. I have the Canon Vixia HF-G30 now and I'm seeing a delay of at 60 ms on it. The Vaddio PowerVIEW HD-22 has a claimed frame delay of 1 frame, but at $4000 that's a bit out of my price range.Īt this point, I am trying out prosumer camcorders on a Bescor MP-101 pan/tilt head. I also tried the Lumens VC-G50, which has less delay (about 50 ms), but the image quality is not as good. The extra 50ms (compared to our tripod camera) is very noticeable in the final output. The lowest latency I could get on that was about 80 ms. So on my path to upgrade to 1080p60, first I tried out the Sony SRG-300H PTZ camera. Total delay is about 200 ms, which is okay but not great.

Right now, my latency numbers from camera input to TV output are something like this (at 1080i):

I point the camera at the laptop running the timer, connect the camera's HDMI output to an HDMI monitor, and then compare the time on the laptop to the time on the monitor. I've been using a Sony HVR-V1U, which is a 1080i camera, and it has about 1-2 frames delay (33 ms at most) when I do a test similar to the above. Now I'm having some issues on the camera end of things, too.
