Alexa Mini & Amira, and timecode compatibility

Gustavo Fattori
 

Hello,
 
 
My name is Gustavo, and I'm a São Paulo/Brazil based camera assistant.
 
In a recent call with an Arri director, he told me the last Alexa Mini and Amira's SUPs has an improved and safer timecode protocol; so, after this changes, some sound recorders, sync boxes, and even electronic slates won't be compatible to sync timecode on cameras anymore.

Of course a safer protocol is a great deal for the camera assistant, but it worries me specially on Denecke case, in my personal experience the most common syncbox brand here, and one of the brands the guy quoted as no longer desirable in a work with Mini.
 
Is there a list with the compatible and approved hardware, and also with the no longer certified ones?
Sometimes, on a feature or tv series, the day when camera and audio teams come in a meeting to do a complete check&test is already too late to change the audio rentals, and would be great to send them a safe list of recorders, boxes and slates...
 
 
Thank you so much,

Are there any more details available?

Why is it incompatible with hardware that's been on the market for many years?

And what was the problem with SMPTE time code, THE industry standard for decades?

I was, frankly, surprised to read this, since my past experience with ARRI's support of timecode (and genlock) has been that it was a gigantic pain in the ass to deal with on a professional level on multi camera productions.

Hello Bob,
 
it struck me deeply. 
First of all I've tried to post it at the Arri Forum, the natural step involving an Alexa technical issue,  but as nobody aproved me to enter there, I'm trying here on CML... It will be awesome to read more details about it.
 
I hope it won't be more than a misunderstood (so my appologies in this case), but if it's a solid fact, some hardware compatibility list should exist.
 
If any Arri (or even Denecke) could help us here, I'll be sincerely thankful and relieved.
