Re: Atomos Shogun Inferno?

I'm liking the 48/50/60hz switchable display refresh rate feature, and of course the certification for PS4 Pro HDR recording. When I get one, I need to find time to test it on a Nvidia Pascal GPU.

Re: Atomos Shogun Inferno?

A bit more update on recording FS700R's 2K RAW signal @ 240 fps to Apple Pro Res files with the Inferno...

I'm an amateur, not a pro, so please bear with me...this may not be news to some folks: The Inferno's "Pre Roll" recording function (i.e., same as "End Trigger") must be caching Pro Res file data in its buffer (not the original 2K RAW signal).

Why do I think this?? Well, because I just performed a series of experiments using Pre Roll recording of my FS700R's 2K RAW/240fps signal to the Inferno where I varied the Apple Pro Res codec that the Inferno uses from HQ --> 422 --> LT.

The results: Set to Pro Res HQ, the Inferno gave me slightly less than 1 second of Pre Roll buffer time. At Pro Res 422, it gave me about 1 sec of buffer. At LT, the most compressed of these three codecs, the Inferno gave me about 2 seconds of buffer time on Pre Roll recording of the 2K RAW/240 fps signal.

Next question to answer, and this is obviously a more personal one, is: Is the trade-off of codec quality going to be worth the precious bit of extra buffer time? I sure hope so, because 2 seconds is comfortable while less than 1 second (at HQ) is not a comfortable reaction time for Pre Roll recording.

We shall see...

P.S. Agree completely with Jack Zhang concerning Rolling Shutter....the ruination of pan shots at lower frame rates.
