Wireless feed from RED

[roryhinds]

just wondering how people are planning to get a wireless feed from the camera?

Anyone know a good solution to get HDMI 720 wirelessly?

[Simon Blackledge]

Only know of the Gefen one, but sure there are others.

I would be very interested in wireless HD options if other people know of additional resources on this topic. Since I do a lot of Steadicam work, it would be a godsend to just attach a transmitter to my rig and forgo tangled tethering messes where possible!

Philips has their wireless HDMI kit for $299. It's basically the same thing as the Gefen one, actually I think Gefen is using Philips' chipsets inside their unit. The Gefen is nice in that it also accepts additional audio input as well as dual HDMI and a component input that can be converted and the user is able to switch sources. This isn't as practical for RED though... The Philips unit just has a single HDMI in on the transmitter and a single out on the receiver.

Unfortunately with such a short range (about 10m) and that the Gefen and Philips employ JPEG 2000 compression and image enhancements, I'm not sure just how great this is going to be.

[Jeff Kilgroe]

The Philips unit might not be a bad one to try, Haakon. As long as a set monitor is within range, or even on you depending on your steady setup, it should be fine for this. I don't know about power draw though and if you'd be able to rig the transmitter up to a battery pack.

powering these is an issue

Wireless 720P HDMI would be very cool...

I don't know the Philips unit, but it looks more like a consumer market oriented product...
Not sure it would work well for us, considering our needs. As Rory said, powering it may be an issue. Also, the range is quite small (and most of the time, it's less than advertised). And the fact that you will probably be moving the camera with the transmitter on it makes it even worse.

But hopefully, someone will look into this matter and use this chip or a similar one to make a unit that would be adapted to our work. Red guys, here's a new challenge for you :) (well, ok, finish the camera first...)

I've been using "the boxx" for some time now (www.the-boxx.tv), and I'm very happy with it.
Basically, it's a digital wireless transmitter / receiver that works on the Wifi frequencies (you can choose between 2,4 Ghz and 5,2 Ghz). But of course, it isn't HD, just SD (composite and component inputs). Only downside, the realtime mpeg2 encoding takes some time, about 1/2 second, so you have a small delay.
They also seem to have added an HDSDI downconverted option, so I guess you could plug it into the HDSDI output and use it with Red. But the transmitted signal would still be SD.
If I remeber well, price was around 3000 € (transmitter+ receiver) one year ago.

But I would really love being able to transmit an HD signal using the 720P HDMI output !

Going truly wireless is difficult on a budget. The director and DP want to see the camera image at video village, hence these low cost wireless HDMI options. What about audio? The Gefen box does transmit audio. But unless you do a true double system, your going to need a very reliable and clean audio path TO the camera. I wouldn't trust my only sound recording of a shoot with any wireless (including Lectrosonics). I plan on just building a snake cable that has HD-SDI video, 4 balanced audio cables (stereo to and from), DC power to camera and maybe control for remote focus pulls. A snake cable will fit my needs 95% of the time.

PS I really don't even know how to deal with wired HD-SDI monitoring yet on a budget. I just feel that these wireless HDMI transmitters are not the answer.

I'm hoping for something that might help us get a look at the magic focus while on a Steady rig. And that means coming from the EVF connection on RED (which is what I think some proprietary version of DVI, does anyone know) its quite a different task.

lots of folks working on various wireless HD solutions -

the future is not TAPELESS ... it's TAPELESS and WIRELESS ...

I expect some very exciting integration possibilities with the RED camera in the very near future -

For the record, the HDMI is 720/60 all the time - so, for client and steadicam that's cool - but some of us would like to get PROGRESSIVE frames and accurate TC wireless for tagging additional meta-data etc. - I have not seen an inexpensive solution yet that will do 1080p with audio and TC with RT accuracy wireless from an HD-SDI - (please let me know if any of you find one)

I suspect given new wireless standards in the VERY near future - we can just stream the REDCODE RAW data off the camera and DECODE on a BOB - Now THAT is a nice product for RED to develop!!

You can always use the Philips by hooking into a small lcd with HDMI and have the Director track along within the 25ft. range.

It's not a very elegant option I know, but you'll see directors on mini wireless taps all the time on big sets.

This is where I'd still be favouring an HD-SDI output so that I can downconvert to SD and transmit for Steadicam use.

For now I need to maintain the investment in transmitters and recievers that we made so far and still use for Film jobs.

I've toyed with digital transmission systems but the cheaper ones tend to have a large delay (up to a second sometimes). There are great HD transmitters for broadcast work but they climb in price and size.

[dalemccready]

...and personally I find nothing worse than doing a hard steadicam shot with the director stumbling around your ankles trying to get a squiz at your monitor ;)

[Alexander Nikishin]

Dale, are you using a Hermes?

Stuart has said in the past and Im reading between the lines a bit:) that there will be a HDSDI monitoring output but I am not sure if it will be suitable to use to record from camera. I'd be interested in the delay in respect of using it to operate the camera.

I think also the audio issue is at a wireless system a point. would be fine to transmit the 4 channels from the mixer to the cam and the control tone back from the cam to the mixer. a digital multiplex system would be fine or a transparent HD-SDI tunnel or something like that.

I think Mark is right. Purpose built solutions for wireless HD monitoring will happen sooner rather than later. There is a lot of R&D going on for wireless home networking at HD bandwidths and for mobile video distribution that should provide cost effective pieces that would solve some of the stickier issues this tech presents.

The right engineer(s) working with someone who understands what folks like us need should be able to offer quite a value proposition...

Not that RED couldn't do this well, but they have a lot on their plate. Maybe the Red Leader can find a couple guys in a garage and give them the resources to make this happen... (Pssst - look for two guys named Steve :whistling: )
