Is the VSYNC signal (out of a VGA adapter) an OK way to measure and analyze the frame rate and clock output of a prosumer video camera spitting out HDMI? My goal is to determine if the TC OUT of cameras is generated by the same circuitry that reads out the image sensor... if not, an easily detected drift will occur between the two clocks (and that would be a shame: I know #timecode is not genlock, but sapristi, c'est supposé être un signal de synchro). Surely the DACs inside this adapter introduce some lag, but it should be constant and therefore won't produce any phase roll between VSYNC and TC.

Can anyone tell me what the standard GoPro Hero 10/11 matching TC for double-system should be? Given it runs at either 30 or 60 fps, run 30ND for standard 30fps recording? And straight-up 23.976 for 24 fps in 4K? Thanks in advance. Tom

Not sure if anyone else experienced this but I just started a show with the Alexa 35. After 2 days, they will no longer accept timecode from the JB1 sync boxes. Switched out cables, different boxes, switched between the two cameras, changed output levels on boxes. Nothing is working. They will take the time code but eventually give an error code. However, the cameras do take Ambient sync boxes. Would love to solve this as I’m sure there is something we aren’t thinking of. Thanks, George

Hello, I wanted to know if anyone has run issues with running timecode to the Sony Fx9. I didn’t have time to troubleshoot the FX9 last time I worked with it so I ended up just sending a camera hop for reference. I tried to use a jb-1 denecke and a 664 to send timecode to the camera with the settings stated in the manual but had no luck with it acquiring sync. I tried to toggle through the timecode settings in the camera menu but didn’t have time since we were in a crunch. Just curious if anyone has run into similar issues?

Just came off a gig where the 2 cameras were Ursa minis, the menus said it was set for line level, when I listened to return it was buzzing and sounded like it was clipping, I just dialed back so it didn't sound like it was clipping. I of course recorded everything, gave them a L/R feed to camera and ISO record. TC was provided to cam a via my tc snake, and cam b by tentacle and IFBlue scratch as well as using TC slate for each take. I asked several times for playback from camera as I noticed returns had a bad buzz, DP said don't worry, just make sure you record everything in your mixer! Anyone else have issues with the URSA Mini?

Hello hivemind! I had a cable made by Trewaudio for a ARRI Alexa Mini LF. The connector is a 6-pin lemo. When trying to use this cable for the first time, it simply wouldn't fit into the Arri's jack. It is not a bent pin issue (they're aren't bent)...in fact, the lemo connector on the cable won't even go in far enough to connect to the pins. So question: 1) Is it possible that Trew put on the 'wrong' 6-pin lemo end (is there even more than 1 type?) 2) anyone else run into this problem? Thanks!

Hi everybody, i am contacting you because i am in a shoot where we use a sony FX9 (and FX6 as a A cam with no problem) and the problem is the following : We need to put audio in input 1 with Channel 1 and there is literally no option to set it. How to fix this? See the picture below. The first option is greyed out. There is no external option for Channel 1. The DOP can't help and i set on the right of the camera the channel to "ext" and not "mi shoe". I am hoping someone ran into this problem maybe already. Never saw a camera in my life that is litteraly not proposing you options for channel 1... Thanks

We have been using the rode videomic NTG's on both our Canon C70's and they had been working perfectly. Our camera ops never had to think about them when turning on the camera since they would turn on as the camera would turn on. However recently we've noticed they stopped turning on automatically when powering up the cameras. That now we have to manually turn them on. The microphones themselves are still working fine, it's just that this feature is no longer working. I've contacted RODE and even updated the firmware and done whatever tasks they had suggested. But in the end this feature still wasn't working and they suggested to just send it in for repairs. …

We just opened our internal database to the public...C.A.T.I. - the Camera Audio and Timecode Input database. The goal is to be able to crowdsource new cameras that we may not all come across very often, or discover a camera's idiosyncrasies together. Feel free to use for your own personal use and contribute as much or little as you want. We tried to make it extremely easy to use, but feel free to post any suggestions.

It's not about if a camera should record sound or not... Neither if it's the job of the dop to do it... But just if a camera can technically handle it or not. Here to start with that topic :

Hi Everyone, Noticing an issue with with my Canon 7D internal "in-camera" audio. I would like to use Pluraleyes to do the syncing and have found it works well matching scratch camera audio to external audio recorder tracks. However, the problem lies in the fact that the Canon 7d's "internal" audio from the camera's own mic is not truly in sync with it's own in-camera video. The audio comes in 1-2 frames before the picture. I shot 1920 x 1080 footage at 24p (internal camera settings) with the internal camera audio at it's 48kHz default. I shot a handclap to camera (no external audio at all) and then view the clip it on the FCP timeline : the audio de…

When I send AES 1,2 out on my sound devices 664 or 633 into the Arri Amira set to AES input I only get one channel of audio instead of both. I can’t figure out what I’m doing wrong. When I do the same thing with Sony cameras both channels show up. Any help would be appreciated.

"What is IRIG-B? The IRIG-B time code is used in military, government, power industry, and many other commercial and industrial applications to ensure precise time synchronization. " I know there was a timecode box with a kickstarter or indiegogo that was timecode.io or something for GPS UTP time autoset to SMPTE TC OUT that never made the product as was not funded. With cheap TCXO boxes like Diety and Tentacle perhaps we won't really see it in the field for film and TV. Has anyone worked with the Phantom VEO model cameras and used IRIG-B timecode instead of SMPTE? Was it fed from a GPS receiver at all? Even if shooting at 24fps not high speed? Phantom …

Curious to know what others have been choosing regarding TC rates for double-system in either 5.3K or 4K in 24 or 30/25 FPS? Are these frame rates to be approached like previous TC settings we have come to know over the years (24 and 29.97ND/25 respectfully)? Or is the GoPro a completely different animal? Has there been any tests to confirm/deny drift rate, assuming it will drift without TC? Thanks for your input. Thomas

Do they make a Straight lemo mini 5pin for alexa mini L/R input vs the right angle, and if so does anyone know a part number? First time i ran into this where some gadgetry was mounted on cam blocking the up-right angle plug so i had to go timecode only, but that is how they preferred anyways. Would like to have the option in the future if a connector is available

I am not even sure where to put this topic, so it ends up in the camera department. I've seen some shots on YT some time ago with some GoPro or alike on a boom during take in the past. I can't find them anymore, but it was, in a way, pretty cool portraying our craft. It seems I have a 20min or so sequence shot coming up in a month or so. Hidden cuts expected. Booming this, I'd love to provide some making of footage. So far, the lightest thing my research found was the DJI Action 2, but it's the mounting accessories and their weight specs. struggle me. Has anyone done such a thing in the past or watched it or has any other thoughts beyond "don't put mor…

I have a novel situation and am curious if anyone else has experienced anything like this. It's a long post, so I apologize in advance. I often use 3 Lectro R1a's for camera scratch audio, so they can run off the same transmitter as the IFBs. I converted them to external power running off the camera, using Lectro 9V battery eliminators, P-tap cables, and a milled hole for the power connector. I have a 3.5mm TRS to XLR (tip to pin 2, pin 3 float, pin 1 GND) for audio. This setup has been in regular use, with no issues, for 4 years. Two weeks ago, all three R1a's failed, one after another, on one particular camera. The specifics of the damage are bei…

Heya! I guess most of you are familiar with mki and mkii of this camera. Its straight forward to slap on a TC box, set TC to in, preset, free run and its all thats needed to run smoothly. I could not get it to work on the mark iii today. Has anyone got a similair experience or got any 'gotchas' they could share? Only thing I can think of in hindsight was if the cable was broken or if there was a monitor setting that I didn't catch, but I had the impression that it didn't catch the TC at all.

I'm working on a show with two tiny Marshall car cameras that only output 30fps despite the show being 29.98DF. Does anyone know of an inexpensive, portable video converter to do this? I realize this is not a sound issue but I'm trying to help camera out (and want to make sure my files sync properly). Maybe something like one of those small Blackmagic converters?

Hi, I'd like to get a scratch track into the Arri Alexa. It has a 5 pin xlr connector and I thought it would be as simple as getting a 5 pin to 3 pin adapter and then plugging in a mic. However, I was told because it is a line level input that it is more complicated than that? This is what the manual says "2-channel analog line-level audio can be fed to the camera via the 5-pin XLR connector located at the front of the camera on the camera-right side." I'm not an audio guy, so I'm not sure what is needed, but all I want is a reference track in the footage even if it's not the greatest quality. Thanks

Hi all, I'm about to start a feature with a camera that i have never heard of until yesterday. We will be shooting on the Kinefinity Mavo LF. I saw the camera yesterday and got it to accept TC from my tentacle. TC input is a lemo 5 pin. Pretty straight forward. I didn't managed to deactivate the sound recording though. It either accept external sound from 2 XLR input located on the top (both "pro" level, line or mic level and with phantom power) or has an internal mic. The best i could do was to turn the gain down to 0db but couldn't completely turn it off like on Alexa mini for exemple. Has anyone experience with this camera? Any do and…

Hi All, I haven’t been on here in a while but an AC friend just sent me this and he asked me to spread it around so I’ll put it here and other relevant forums to get the word out. I have no direct experience with this issue but this is a well respected AC who really knows his stuff. Has anyone else heard of this? -Dennis “I want to give everyone a heads up about an ongoing issue with the Sony Venice...
