I'm sharing an update on our intended workflow...and seeking confirmation I am understanding how CINE EI functions correctly. Seeing as we will be taking advanatge of CINE EI mode on the Sony FX6, and following all the very helpful advice online from @alisterchapman, we'll be shooting at 400 EI, so to over expose by one stop, by metering to the on-screen s709 MLUT at the recommended values, i.e. middle grey = 45%, skin tones ~50%, white card 77-78%. My question relates to the C300mk2 settings, which does not have CINE EI mode, yet we want to similarly overexpose by one stop when filming with its Canon Log 2. Cinema Gamut, and so presumably - to emulate the function of CINE EI on that camera - which also has a native ISO of 800, we can simply drop the ISO to 400, and meter for that exposure - which with Clog2, middle grey should have IRE= 39.8, and then once this exposure is reached at ISO 400, we restore the camera to its native ISO of 800, to begin our recording, thus effectively achieving the same as what we achieved using CINE EI on the Sony - over exposing by one stop. Is my understanding correct? Thanks in advance!

Thank you! We will be filming with these lenses: FX6: Sony SEL FE 70-200mm f/2.8 GM OSS II C300mk2: EF 70-200mm f/2.8L IS II USM

Thank you everyone for all of this helpful advice! Reading Doug's advice that we gain little from having timecode sync given the powerful tools now accessible for syncing in post, and also seeing Alister's mention of the potential drift that can occur, especially when we will be recording long clips of 30+ mins, and Genlock bring impossible due to its absence on the FX6, should we forego the BNC cable syncing the 2 cameras timecode all together? Am I right in understanding such drift would cause more harm than good, so we should not risk it? Thank you!

I am filming a multi-day, 2-camera shoot - all in-studio interviews. In the past I have simply operated both cameras independently, and sync’d in post, however I am wanting to sync the cameras properly - so have both cameras share identical timecode, and also – ideally, have the shutters on both cameras opening and closing at precisely the same moment when recording each individual frame, so that each frame from each camera will be a true sync. It would also be helpful if the the B-camera could slave entirely to the A-camera, so pressing the record button on the A-camera triggered both cameras into recording, however this isn’t necessary as their will be a second camera operator. I’m also hoping to achieve the above by connecting the 2 cameras directly vs. using expensive peripherals or “sync” devices, if possible. I have never properly syn’d cameras before, so please forgive my ignorance. So far, I think I have gathered that timecode can be easily shared between the 2 cameras using a BNC cable. As far as having the shutters in sync, I *think* this requires Genlock? I don’t know what this is exactly, so am looking for confirmation as to how I achieve all of the above via Genlock, or through other methods. Please don’t feel the need to explain every detail to a newbie, simply outlining the basic method and pointing me to some more detailed information on YouTube or elsewhere would be much appreciated. Any other workflow advice for syncing these two cameras is also appreciated. Thanks in advance!

We are preparing for a 2-camera shoot in a studio, w/ a controlled 3-point lighting set-up (interviews), with 2 cameras on tripods, so no camera motion, or changing light sources. Of course – we would prefer to use 2 of the same cameras, however we are still in development so cash-strapped and really need to make the most of the cameras we have access to (Sony FX6 & Canon C300mk2) , and so we are seeking workflow advice to optimize our set-up to ensure the images match visually and can be inter-cut. We will be sure dial in identical settings on both cameras (WB, etc.) and will film a colour chart , prior to rolling each camera, so that the colourist has this reference for matching the 2x cameras in post. We also intend to film flat/log on both cameras, so on the FX6: Slog3-S-Gamut3.Cine On C300mkii: Canon Log 2 (which I understand would be the preferable option to Canon Log 3, Canon Log 2 being flatter and more comparable to Slog3?) I usually film in CineEI, and intend to do the same on this shoot. We much appreciate any advice relating to our intentions outlined above, and any other workflow advice for our set-up, given our intentions to inter-cut this footage. Thank you in advance!
