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. wireless-camera-control is a Moteino based standalone wireless controller for multiple pan/tilt heads based on the popular Bescor MP-101, along with provisions for controlling up to three geared motors for the implementation of zoom, follow focus and iris. In my previous test, i had 150-200 msec for a 1080i 50Hertz inputĭisplaying on a 1080 60p computer screen. Pan/Tilt/Zoom remote desktop or ceilingmounted camera with a 1/4 EXview. I prefer hdsdi than hdmi output for lowering the latency. AG-HMC40 AG-HPX170 3-Chip AVCCAM Handheld Camcorder with 10.6MP Still.
(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. 30 BESCOR 259 MP-101 Motorized Pan Head Support cameras up to 6 lbs. I have the Canon Vixia HF-G30 now and I'm seeing a delay of at 60 ms on it. QR-DSR Front Sony Wedge Mount Adapter Anton/Bauer wedge mount adapters instantly. 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): The protective dome for the camera is a 12' diameter, 1/4' thick Acrylic hemisphere from EZ-Tops.Polycarbonate is a much stronger plastic, but it isnt optically clear, it scratches easily and it cannot be made into a true hemisphere. 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. The roof-cam base is made out of wood and has a Bescor MP-101 motorized pan/tilt head mounted inside. 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.
