Hi guys,
Today I had a shoot and encountered a strange problem with audio/ TC. I shoot mostly 25FPS here but today we had a USA client who required us to shoot 23.976FPS. So I changed the timebase to 23.976. First thing I notice is my TOD timecode changed...it was actually around 50mins slower than that of other timebases! We didn't think too much about it and proceed to feed audio into the camera. That's when the problems occur.
Firstly, once the 1/8"-XLR is attached to one input, the touch screen stops responding. By that, I mean I can still access the menus via my side handle but i can't change any settings via the touch screen. Secondly, when the sound recordist switched on the 1k tone, the audio meter is flickering like crazy.
Since we all the intention of dual recording for audio, we gave up on sending a reference audio to the camera and figured we should just sync up the camera with TC from the recordist's 744T and just clap the slate for all our shots...BUT, the camera refuses to sync at all. The TC icon did not light up and the running TOD timecode does not change at all (still 50mins behind). We tried to trouble shoot but plugging out the audio, LCD, reboot and all, but still the TC refuses to sync. We also tried swapping cables. None of that helped.
So we tested other timebases and it seems like we can both send reference audio into Scarlet (albeit only one channel) AND get the TC to sync with the 744T! It works like a charm with 25FPS and 24FPS (didn't try other timebases though). So in the end we shot everything in 24FPS after the client gave the approval. No issues whatsoever (except that the reference audio had a low level buzz that's visible in the audio meter).
So did any of you guys ever experience something like this before? Or is it just my camera??? While I don't actually shoot 23.976FPS frequently, I'm still interested to know why this problem occured. Anyone?
