You made the comparison to the Sony FS700 but what are you comparing exactly? When recording 120fps or 960 fps, what frame sizes does the FS700 actually deliver? What is the bit depth, the color depth? Are you saying that you would be happy with 120 fps on Scarlet at 8-bit?
Red set the quality bar at 16 bit 4:4:4 and I love that. 8-bit is sub par for a professional tool in my opinion and I don't want to see it cluttering my menus, but my real concern is not the clutter. I know that if the option exists to jump down to 8-bit or lower color depth etcetera then someone is going to insist that I use it and frankly I don't want to give up that quality, particularly for a shot that is bound to be an attention getter. It is not a conversation that I even want to have so it is better for me if it is not an option.
If 120 fps is required I am happy to rent Epic, but that's just me and my personal preference.
