shug Posted June 25, 2018 Report Share Posted June 25, 2018 Hello guys, i was wondering if anyone has ever worked with this particular set up before. The Arri umc-4 is an external follow focus brain. Unfortunately it uses the sync input (where we normally plug in timecode) of the RED. The umc-4 has a regular timecode input (5 pin lemo), we can get timecode to read on the umc-4 but it doesn’t go through to the RED. Has anyone worked with this particular setup before? Thanks!

AspiringAudiophile Posted July 26, 2023 Report Share Posted July 26, 2023 Too bad no one responded. I'm faced with the exact same problem on a 2 camera feature for 3 weeks. We've resigned to just jam the camera directly at beginning of the day, at lunch, and if they turn it off. My guess (or hope) is that the UMC-4 is only using certain pins of the Lemo 4 Pin Sync Port for its control data, and the Red could possibly still take a timecode box if there was some sort of splitter to both the focus and timecode boxes sharing the Sync port. 🤷♂️ Quote Link to comment Share on other sites More sharing options...
The Documentary Sound Guy Posted July 26, 2023 Report Share Posted July 26, 2023 Yes, the best solution here would be a custom cable that gives some sort of TC in on the TC pin, and allows the follow focus control on the other pins. I don't recall the correct pinout, but it should work. I would check the RED website to see if they have a cable that works. It's their design, and I do recall hearing that the cable existed from a camera person back in the day. A micro 4-pin lemo would be a bitch to make a splitter cable with... you'd probably need to splice in the cable rather than taking two cables out of the connector. I'm surprised that, if the UMC-4 can be jammed, it doesn't pass timecode ... my imagination is failing me to think of any reason it would need a TC signal other than passing it through. It makes me think there's a setting somewhere that would make it possible, but I don't have any direct experience with it. Quote Link to comment Share on other sites More sharing options...
