I have been unable to try it with an external recorder yet. Would you say there's a big jump in resolution/ overall quality?
would love to see some sample footage if you have any.
On static stuff, for most things, I basically see absolutely zero jump in resolution compared to IPB internal.
If the entire frame is moving all over and especially when focus is nearly but not quite in focus on some detailed area of a frame and the whole frame is moving and focus changing the external has wayyyy less compression artifacts than IPB (however, that might not be the case compared to all-i, didn't test that yet). Frame by frame it's a huge difference for some frames. That said, in real time, at least on a 24" screen (even sitting really close), the differences all sort blur much more together to the eye and you have to really keep your eyes peeled like an eagle.
Sometimes if you have something like white text surrounded by solid block of color, the white text can be a touch crisper and sharper with the external recording (but there is, oddly, that MORE noticeable transition band on the left hand vertical sides of it though which is kinda....). Not sure if that is a Ninja thing, prores thing, PP CS6 thing, 5D3 thing or something I'm doing wrong.
I could swear that ALL output, internal or external, with 1.2.1 is a bit crisper and more detailed than before though, same shadow detail but things have a touch more contrast/detail/pop in general and areas of low contrast detail don't turn quite as waxy as before it seems. Still not like C300 or anything though or like some of those 'raw' DNG frames people are posting.
