Hi everyone!
I'm curious if anyone else has encountered issues when jamming an Ursa Mini 4.6k. Recently got the camera and I love it so far, but I was doing some tests and can't seem to figure where the problem lies.
Using a Sound Devices 744T, I jammed a Denecke SB-3 and used it to continuously jam timecode to the camera. I also sent reference audio through a hardwired breakaway cable. I synchronized the files in Premiere and the timecode on the footage appears to be just under three frames late. The video is in sync with the reference audio recorded directly to camera, but what was recorded on the 744T is not lining up.
I tried it again with a different recorder and syncbox, a Sound Devices 702T and Ambient ACL204, as well as a Denecke TS-3 to visually reference. I encountered the same issue where files were nearly three frames out of sync. The timecode shown on the slate and the audio files match, but video is out of sync with the slate. I should state that in both instances I'm certain the settings were correct on all equipment, 23.976fps 48KHz. At least it appears to be consistent so it should be simple enough to adjust in post and get close enough, but it does bother me that it's not exactly in sync. Also I hope it is something that stays constant and doesn't drift further over time.
Any insight how to fix this would be greatly appreciated! Maybe it's a completely separate issue that I'm not thinking of, perhaps in Premiere? Or if it's just a matter of compensating for it, I can live with that. I'll do some more lengthy tests and see what happens, maybe export an OMF and drop the "synchronized" files into Pro Tools and see exactly how far they are apart they are in milliseconds and samples.
Cheers!
