Premium Members Justin Besser Posted July 20, 2013 Premium Members Report Share Posted July 20, 2013 Have a job from Monday running a f65, couple of questions to ask as I have not run this system (apart from yesterday's gear check) My rig- GPI PRO cinelive + gen4 base (with 3rd battery pos) Cinetronic gen2 Anton Bauer dionic HC Teradek bolt Bartech I was reading how the cinetronic back feeds power to the sled and I am wondering about the adverse effects of having 3 batteries in parrallel on the one circuit on that sled/monitor combo.. We will be shooting off speed and I had heard about the enormous power consumption of the camera, especially shooting off speed. I have 14 batteries + 3 chargers (tm4, tq2, 2702) Shooting in a remote desert location Also shooting in low mode and have the sled totally extended with 4 batteries attached and still not able to get the gimbal too far from the stage, any ideas without having to add more weight to the bottom Any other tips or advise about shooting with this camera? Also attaching the teradek, would it be ok running on the base and not the camera, easier for me to power and in an remote area, nothing cept open space, no rf interference, or keeping it at the highest point in the system is best? Cheers, Justin Besser Quote Link to comment Share on other sites More sharing options...
Premium Members Ken Nguyen Posted July 20, 2013 Premium Members Report Share Posted July 20, 2013 Use F-bracket with longer arm post (12") to get the camera closer to the ground. I think a supper post is best. The fully extended cinelive is still too short to put that camera close to the ground. Shooting in the desert this time of the year you need more battery than 14. Last month, I used 20 of them. The camera and recorder swallow 100w. The heat of the desert also makes your battery drain out faster than normal. Cheers, Ken Nguyen.

Premium Members William Demeritt Posted July 20, 2013 Premium Members Report Share Posted July 20, 2013 I had issues with getting an HD Image on my gen 2 with both SDI ports. I think it had something to do with the P V's PsF issues. I didn't have enough time to troubleshoot it, but just be aware. Quote Link to comment Share on other sites More sharing options...
Premium Members Justin Besser Posted July 20, 2013 Author Premium Members Report Share Posted July 20, 2013 If the camera is 100w And the batteries are rated at 90w/hr That should mean I get slightly less than an hour with a battery at that load, obviously with all the extra bits on the rig and peak loading will be less .. Tested the gen 2 already, seems to work fine.. Have a backup monitor on standby incase anything funky happens.. My issue with it is the power backfeed from the monitor into the sled, if 3 batteries on the one circuit is going to cause issues Quote Link to comment Share on other sites More sharing options...
Premium Members Afton Grant Posted July 20, 2013 Premium Members Report Share Posted July 20, 2013 Have you tested the Cinetronic to get an HD signal from the camera? Quote Link to comment Share on other sites More sharing options...
Premium Members Justin Besser Posted July 20, 2013 Author Premium Members Report Share Posted July 20, 2013 Cinetronic has been tested .. works fine out of both SDI ports .. Quote Link to comment Share on other sites More sharing options...
Premium Members Jens Piotrowski SOC Posted July 20, 2013 Premium Members Report Share Posted July 20, 2013 Re: backfeeding. I have you have a battery on the back of the Cinetronic it powers the monitor. If you feed SDI into the Cinetronic, there is No need for the 8 pin Lemo cable whatsoever. So therefore there is No chance of backfeeding. 1 Quote Link to comment Share on other sites More sharing options...
Premium Members Eric Fletcher S.O.C. Posted July 20, 2013 Premium Members Report Share Posted July 20, 2013 While yes your batteries are 90W/hr you won't get more than 30 mins out of them when you are pulling that load. It has to do with the way the current ratings are averaged and the droop on voltage as the batteries are being run down Quote Link to comment Share on other sites More sharing options...
Premium Members William Demeritt Posted July 20, 2013 Premium Members Report Share Posted July 20, 2013 Cinetronic has been tested .. works fine out of both SDI ports .. I don't mean to derail the thread, but what were your settings on the HD output? Just so i can avoid the issue in the future should I every fly that pig again.

It's my default setting for that camera Quote Link to comment Share on other sites More sharing options...
Premium Members Lawrence Karman Posted July 20, 2013 Premium Members Report Share Posted July 20, 2013 Also shooting in low mode and have the sled totally extended with 4 batteries attached and still not able to get the gimbal too far from the stage, any ideas without having to add more weight to the bottom Move your monitor up higher towards the bottom. Move the Teradek to the bottom. Use a super post if you need to get to ground level. And if speed in switching back and forth between low mode and regular is a concern avoid regular low mode and just turn the rig over without flipping the camera (shoot upside down) and invert the image in the camera menu.

Premium Members Justin Besser Posted July 21, 2013 Author Premium Members Report Share Posted July 21, 2013 Job specifically required a Sony 4k camera.. Initially was specced as f55, but due to firmware not having capability to shoot off speed at 4k yet had to change to f65.. Wasn't ideal.. Not menus were touched with regards to the SDI output, but I'll check and see the settings on Monday.. I'll give a rundown of how it goes if anyone is interested..

Premium Members Jens Piotrowski SOC Posted July 21, 2013 Premium Members Report Share Posted July 21, 2013 from the manual: SDI OUT connectors output format: Setting the camera main video format automaticallydetermines the signal format that is output on theSDI OUT connectors. Camera SDI-out23.98p 23.98PsF29.97p 29.97PsF59.94p 59.94i24p 24PsF25p 25PsF SDI OUT 4:2:2, BNC type (2), HD-SDI signal,BTA-S004A-compliant, 75 ohms,0.8 Vp-p, 1.485 Gbps that would not be good, since the Gen 2 will not accept 720 PSF at this point does anybody know if this would fix the issue for good? http://www.decimator.com/Products/MD-DUCC/MD-DUCC.html Quote Link to comment Share on other sites More sharing options...
Premium Members Justin Besser Posted July 21, 2013 Author Premium Members Report Share Posted July 21, 2013 I had it running all day Friday, gen2.. Camera was set to 25p, So whatever it outputs on SDI, it was working fine.. Teradek was transmitting signal fine off SDI-2 Quote Link to comment Share on other sites More sharing options...

The gen 2 was not. I wound up doing Decimator and SD input. Quote Link to comment Share on other sites More sharing options...
