Has anyone tried a modules or wireless video monitoring with the RED? Does it work with a HD monitor and receiver?

Regards for any info.
 
I have done a fair bit of transmitting using an AJA 10DM3 Downconverter and Titan Tx/Rx. Works great.
 
What worries me about it is potential delay with all that compression happening for wireless HD, causing possible remote focus pulling problems. Any experience ?
 
For now the only reasonable solution remains the downconverter to SD transmitter. This works just fine and neither Modulus nor Canatrans appears to bother the RED.
 
Think on the bandwidth of the HD-SDi signal which should transmitted. There is much more technical work to do as on SD. So as Anders his combination described, we use the same and its really ok....

Mitch,

Do you rent these? I have a feature in the works that I may DP and will need to transmit. If so...what would be the weekly rental.

Feel free to PM me.

Regards,
Danny

Thanks to all for the info. Keep the solutions coming!!!

How have you been powering the aja & titan tx? Do you need a power break out box of some sort for the camera?

No offence but your focus puller shouldnt be pulling off a monitor - unless it's amateur night.

You are so right. No focus puller should pull off a monitor. However I think he is talking about signal delay. A wireless video transmitter signal often interferes with a wireless focus system if they are close to one another.
 
While one should not pull off the monitor, one often uses the monitor to know what the cue is for a focus pull.

You too.

Sorry guys, I guess I have been doing it wrong for all these years, using the necessary tools when it was appropriate to do so. I should have asked you guys first. Now I know better. We have such all-knowing experts here on RU!

How would you suggest I focus remote crane shots, car-to-car from a chase vehicle, helicopter mounts, car mounts, running chase sequences, camera on a remote control car, etc? How about a Technocrane at a live rock concert with no rehearsals?!?

Is the camera operator still allowed to look at the monitor?

-sheesh!-
 
why? what's the difference? pros and cons of evf vs monitor? thanks.

While a bunch of folks on this forum have argued the point, with extremely few exceptions, no decent AC will pull off a monitor. The simple reason is that if you are watching the monitor you aren't watching the actor. Obviously you can't see his marks on the monitor and can't tell if he came up short or long. You are also reacting on a monitor which means that by the time you realize whats going on, he's soft. Plus you can't really judge on a monitor if you are shooting film, or RED. You can judge focus on a nice big monitor on 720 or 1080p stuff. AC's trust good lenses, and trust in math. Knowing your hyper-focal distances is very helpful, as is a very good understanding of depth of field charts. P-cine is an excellent program, if anyone knows how to get it on my I-phone, please tell me ;-)

All that said, there are a few times where focusing off a monitor is OK/the only way to do it. Like 135mm wide open on a guys face, mouth only, tilt up to the eyes. The depth of field is so shallow only bits of it are in, and you have to pick which bits you want (you want his close eye, or his far eye?)

See my post above.

It is possible to position yourself in such a way as you are looking at the monitor, the lens, the focus dial, the actor and their marks. It's called peripheral vision and it is part of the art of being a focus puller.

Keep at it. You'll learn how to if you keep practicing. I've done major features with all of the above and have never used a monitor to pull. Yes, to see exactly what the camera is pointing at but a monitor is just not accurate enough to trust for focus.

Once you know the focal length, stop, and distances of the subject it will all fall into place for you.

Howdy crewpix,

No disrespect intended, I was actually typing my post when yours popped up, so I was not responding to you.

Your examples are some more good ones and I am not personally attacking you. But on a set, on a dolly, or steadicam or sticks or handheld, even on a really good tap like the XL or an Arricam, you can't trust a monitor. I am not saying that the monitor is not usefull, but I think you would be hard pressed to find a good AC who would trade a tape measure for a transvideo.

Gee...I wonder how they did it before video assist?

The point is a GOOD focus puller. Not some schmuck that has to depend on the thing.
