Question to Paralinx Arrow owners

[Alexey Milokost]

Hi everyone,

Anyone using Paralinx Arrow with wireless focus? Is it good for a critical focus pulling? Any delay issues? Do you advice to get one for focus pulling?

Thanks,

Alexey

Hey Alexey, welcome to the forum!

 

The Arrow is uncompressed HD with zero latency (literally below 1millisecond). Most of the focus pullers I try to use prefer to be near the camera on set, but if they need to be near the monitor for critical focus or other reasons, I'm generally not concerned about using the wireless in this manner.

 

The HD quality is sufficient to determine focus well enough through just the image on monitor, and the latency is negligible so the delay is no greater than a wired video feed (considering the LCD monitors all have an inherent delay of a frame or two).

thanks for a reply! I used Teradek cube and the delay was too long for a pull. Anyone else using Arrow for a focus pull?

I haven't had any AC's complain about critical focus issues with a Paralinx. You can always email Dan at Paralinx, and he will be glad to help you out. If you're in LA, he may even be able to demo a unit to you.

I already contacted Dan at Red User. I know that people say it's almost zero latency. I just wanted to know if anyone was using it on a commercial shoot as a puller. I'm sure that for a Director's monitor that a great solution. Unfortunately, I'm not in the States to test it out, but thinking seriously to buy it.

Like I said, I have had 1st AC's use it to judge critical focus, and they have not complained.

With nearly all HD transmitters I've seen a small but quantifiable loss of sharpness due to the raised noise floor. You can see it on the waveform (where what should be a sharp line becomes a fuzzy line) and it manifests into the image as a slightly softer image. There are times that I have called for focus check on the camera only to follow up with "never mind, it's the transmission". It's usually quite subtle...but then again, so is critical focus.

Yup between that and transmission delay it puts the focus puller at a disadvantage

In a word you can use it as an aid to focus but should not rely on it solely.

Thanks everyone, I'll buy it. Unfortunately, no way to test it(
