What size are you thinking? I would have suggested seamless, since it’s an obvious choice.

Mobile Cyclorama

David De Souza
 

Hello Everyone,

 

I was wondering if anyone knows of a way to create a mobile white cyc? Something more durable than seamless paper or cloth. I would like it to be as close to a permanent white cyc as possible with the flexibility building it rather quickly and taking it away at the end of a shoot. Thanks in advance.

 

Best Regards,

Re: Settings on Cinetape

chris.applemac@...
 

The manual was always vague on the real use.

Think of it like this, 
At 1, the readout tells us to the inch when an object moves. At 2, the resolution is now only 2 inches.

At a positive value, it will readout constantly even if the object has not changed distance, i.e. it will constantly update 5'5" as it senses. (depending on how you set your sensitivity.)
At the -1 or -2 value, it will not change the readout until there is a definite change in the subject distance, (i.e. movement starts to happen.) I personally do not like this mode as its not very accurate and the display can sometimes seem like it's stuck. I'm used to the jumpy numbers.

TL:DR the minus values are less jumpy on the display and will only change when there's definite movement. 


Re: D-tap voltage

Roger Phenix
 

some batteries with multi-D-taps on the side specify a max current supplied at each.  Some plates with D-tap have a built in replaceable fuse.  So one can't assume it's always "direct from the battery".  Usually the spec sheet will warn you if battery damage, through misapplication or defective cabling, is a possibility.

No, they dont
the original idea of D-Tap was ro drive lights on Betacams. So they were connected direct from the onboard battery, and was not regulated to provide the maximum current available.
Its assumed D-tap is 12V, but could be up to 16V with lithium batteries.

I am comparing the on-board 12v batteries specs. The D-tap conexion states de Amps but never seems to specify the exact voltaje. I´m wondering, do D-Taps provide always regulated 12v because that defines the standard or do they provide what voltage the battery state is. Same for the D-taps in on-board battery plates and so on.

Re: D-tap voltage

Roger Phenix
 

Hawk-Woods makes adaptors that are regulated.  They have a plate that provides 4 D-tap sockets regulated to 12V.  They also make cables with in-line modules to regulate voltage to 12 v.  It's possible that these will down-regulate from 16.5 to 12 v, but perhaps not up-regulate from 7 to 12 (?), but you can talk to them.

Re: D-tap voltage

Graham Futerfas
 

On my Movi Pro gimbal, where I use DJI's TB50 batteries, I have a special cable made that runs an extra D-Tap output straight off the batteries. It’s 26 volts, not the standard 12-16 volts, so I have to be careful which accessories I plug into it.

I chose a D-Tap connector for this accessory cable because I own so many D-Tap cables in my kit, but the battery plate also has a Lemo output if I want it. The Movi only offers a limited amount of current draw through its built-in D-Taps, so I mostly use this as an additional accessory port.

Most accessories these days, like wireless focus MDR’s or wireless video transmitters, are tolerant up to 30V, so they work very well, but some aren’t. For example, Preston MDR 3 and 4 are 30V tolerant, but the older MDR2 is 12V.

I don’t usually run the camera from this 26 volt port, but RED’s are 11.5 to 17 volts only, while Arri is happy with 10.5 to 30 volts.

Best,
-Graham

There are some plates and cables from various accessory makers that offer P-Taps with 12v regulated power.

No Voltage Regulation with a standard P-tap.
You can be getting up to 16V from a fully charged Anton Bauer battery.

Thanks for sharing Dan. I’m the vice chair of the BECTU Camera Branch in London & I’d just like to make it clear that this BECTU document is a draft that was never really meant for publication - it’s been put together by the ADs Branch for consultation with other branches, & Camera Branch hasn’t had any input yet. It got out onto social media at the weekend somehow & made for a very busy Saturday for me ;-)
