I've flown the Sony Cinealta quite a few times and am comfortable with and the Miranda/everitz box downconverter karate-chop action. However, I've got a Varicam job on Monday and I would assume that the small Miranda fits on just like on the Sony? Yes? All is as simple as one should assume it is?

Brett,

"I would assume that the small Miranda fits on just like on the Sony?"

NO!!!!! If you are talking about the RGB downconverter that sits on the side of the Sony, it will not work. The Varicam is native SDI out, so you need an SDI to NTSC converter. Evertz and AJA make models. Both are reasonably sized, but larger than the Miranda you mention. No fears though, as they Velcro is place nicely, require only two cables (one in and one out). Plus, the Varicam is smaller, shorter, and lighter than the Sony. Also, by having SDI built in, you can give the DP an HD image by running a signal BNC if needed. If you do this and opt to have a lightweight "jumper" BNC between the camera and vest, use 75 Ohm cable and limit yourself to as few elbows and barrels as possible because you can cause signal loss.

Good luck.

Thanks very much. Now I can contact the Rental house and cancel the Miranda I ordered and replace it with an AJA.

And as per a previous comment about this forum and its descent into the depths of degredation (with a capital D that rhymes with P and that stands for POOL!), it's nice to see that generosity has NOT left the building.

Good thoughts and cute massage therapists for all who fly...

Hi Brett

Please note that the Varicam SDI is not the same as standard Sony style HDSDI as it is 720 and not all monitors will read it or converters read it.

Hey Brett,

Ask for the AJA HD10MD3, HD to SD Digital Downconverter. I own this unit and a Varicam. The unit requires dc power. I have a cable that AJA sells that provides power via an Anton Bauer power tap on the camera. Hopefully the rental house will have the power cable and the camera has a power tap.

The downconverter works really well.

Like Alec says the SDI out is really cool. I have replaced my Steadicam Monitor with my Panasonic LCD HD monitor. Since the Varicam has SDI out, the single cable to the monitor makes it really easy to get HD viewing while flying. That was a treat to say the least.

This is my first post to the "new" board. Great to be contributing!

Later,

Ron Borden

Brett,

"I have a cable that AJA sells that provides power via an Anton Bauer power tap on the camera. Hopefully the rental house will have the power cable and the camera has a power tap."

The AB power tap only provides power out with a battery ON the camera, so if you are powering the camera from the sled, this will not work. I had cables made to go from my sled's junction box to the female AB power tap so I could use this method to power down-converters without being forced to carry a battery on the camera (I was sick of asking rental houses if they could give me a down-converter to 4-pin XLR cable).

Sometimes the rental house will give you a cable to power the down-converter from the Hirose on the back of the camera. While this port remains active when powering the camera via the sled, I don't recommend it, as the amount of amperage can (in some cases) cause the fuse to blow in the camera.

Good luck.
