So it appears to have been a multi level issue. 1st. The a7sii that was feeding the flame only feeds 59.94 out of the hdmi output according to the DP. So he was telling me 23.98 and I was matching that with the erx. Because it was actually 59.94 into the flame it would not jam to 23.98. Once we figured that out I switched to 29.97 and it would jam temporarily and then lose code just as quickly. After turning off auto TC function on the Erx it held code, all though if the cable was bumped on the erx it will still lose code temporarily and the rejam almost as quick. Not sure if this is a bad cable, bad jack on my erx or just the limitations of a 1/8" mini connection. I have a new cable on the way and will check with a different erx as soon as I get a chance. Does anyone make a locking 1/8" to bnc and will it lock down on the ERXtc3 ? Thanks for the help ! The unrecognizable frame rate warning on the flame was when I was still feeding 23.98 but had turned off the auto TC feature. Thanks again. !
