View Full Version : RED drive shock mount

I gather the REDdrives are G-force vulnerable.
Any plans for a Shock mount?
Third party?
Could be a simple cube with rubber bands hangin out the back of the camera.
I figure it works for microphones.

you know what? not a bad idea.

You know what. IT IS a fantastic idea. Good thinking.
Only problem there is RED is on the move unlike a compressor mic in the studio - imagine swinging RED around during shots and have one of the bands snap... be nice to avoid the great projectile red-drive incident of 2008, yo...
perhaps SPRINGS are a better idea. We could kind of attach the RED-DRIVE as you would the mat of a trampoline? (but obviously with less tension)

What if you just put it in a backpack full of packing popcorn?

so now you can eat popcorn whilst making a movie!
Awesome.

I think using CF or Red RAM would be a more viable option though...

I think that it might be something with rubber seats at the mounting points. If you look at how a motorcycle case attaches to the frame or the way a car door has seals and small rubber mount points.
THis helps reduce vibration. I plan to use a lot of CF cards (4-10 minutes each) and use the RED drives for storage and longer interviews, etc. The real power of RED is going to be in the CF cards. THey are solid state, they are inexpensive, they are re-writable but inexpensive enough to shoot on and keep. Think of the CF cards as a roll of film or a mini tape. They are (will) be about right between the costs of those two mediums.
There is much talk on these boards about how to back up and where to store two versions of media, etc. I think that the CF cards, when you start using them, are going to eliminate much of this discussion.
You barely ever double record tape or film, and eventually the CF cards will be seen as that type medium, as or more reliable than tape.

Most field boom mic mounts involve rubber-band suspension... works fine for me!

Bingo. No moving parts. End of story. :shiftyph34r:

LOL - rubber bands are for flicking at other people, not mounting bricks :D

No... not end of story.
CF will not be an option in some formats/situations and RedRAM is not exactly cheap though it runs about as long as a typical tape. Directors may/will occasionally want the camera to roll longer than these options allow; people may want alternatives to more expensive media.
You just have to look at how Peter Jackson shot CTL. The drives ran almost non stop! Shooting discipline can/will/SHOULD go out the window in some situations and shooting ratios be damned...(can't believe I said that).
Documentaries, live concert footage, wildlife, chopper mounts, interviews the list goes on and on. Sometimes its just damned difficult to get to the camera!
A G-shock elastomeric mount will help protect the unit from rough handling by technicians/ACs/me and may increase the life of the drive and/or footage.

Definitely should be considered.

The nice thing to consider about some of these situaltions is that because of the camera's modular design you will be able to mount the drive in a seperate place, as far from the camera as the e-sata cable will allow.
I'd say that the situation being discussed in this thread is how to isolate the RED drive (which would need to be act as a recorder for more than a ten minute continuaous roll) so that the shock or movement that the DRIVE, (not nessesarily the camera because they are technically not connected), might absorb can be minimized to prevent the drive from not being able to capture media or skip.
CF cards are the best solution for this situation provided there are short roll times, but I think that the web site listed in this thread will help somebody build on of those "hanging seventies turntable" type designs for the RED drive that will suit this purpose and absob the shock before it gets to the platters. I would presume that a certain amount of this is already built in to the enclosure.
The key is that the two untis can be separated if the drive needs a shock mount then the camera most likely will too. I am curious to see what big vibration, in a boat, car, motorcyle or plane might do to the recording media, but these are problems that have been solved before.
What is the G Force in an F16 going to do to that mechanism? This is when you might go with a solid state, CF card.

How do laptops do it?
I've had my G4 apart and there's a bit of rubber in there, that's it. I don't think I'd handle a camera that much more violently than my laptop for bumps and the like. At least not while it's rolling.

My apologies... I probably should have stated "end of story in my case". There are tons of uses for the RED drive, like you said. I'm just not going to be shooting any of that. It'll be strictly narrative feature work for me under very controlled circumstances. Having 5 or 6 CF cards around should be plenty.
I just have zero trust for mobile hard drives. I use a desktop because laptops are too unreliable. Hard drives that sit on a desk all day are fine, but no way am I going to strap one to the back of my camera and pray that I don't bump into a door frame. Way too scary.

Did you write the post ibn zeal and pure enthusiasm? Cause that helps in posting.
So, how's orange county these days? Been a while since I was back in the "hood".

Very nice.
I think drop shocks are less of a concern then vibration in most applications. Still, a dropped camera is a very ugly animal indeed and anything to prevent lost media is crucial.
This mounting system must have self defeating harmonics and low frequency resonance overall to minimise vibration energy transfering to the deck heads.

I dont remember:) I defiantly like the anti shock case idea. I might build a special housing for my hard drive and batteries.. like a little film magazine.

First off, I think the "horses for courses" mantra holds in most cases. If you need a long load in a high vibration situation I would just suggest renting a RedRAM unit for that day(s).
My plan is to use RedDrives in the beginning since they offer very long recording times at very reasonable cost. As the various Solid State solutions improve in availability and cost (and I've paid off the cam) I'll jump in happily.

The concept is definitely sound, it just needs to be adapted with a RedDrive customised mount of some sort. HTH
