An external recorder allows one to record at higher bitrates and with better color - usually 422 sampling at 10bits versus 420 sampling at 8 bits. But can you actually see any difference?

The Sony RX0 ii outputs 4K 422 10bit video from its HDM port (according to Atomos). And you can simultaneously record to the sd card and externally - with the Ninja V you just use the record button on the camera and you get two recordings.

The internal codec is XAVC S, 100 Mbps, 420 8bit. The recorder uses ProRes at 422 10bit 850 Mbps!

I shot using Slog2, so all the footage is graded - which is what the high-bitrate, high-bit codec is good for. And yes, some scenes stress the codec: moving tree leaves, lots of details, joggers.

So, in the video you see the internal followed by the external version for each scene.



See any difference?

I can't believe no one has replied to this informative thread, during your process of colour correction, did you feel the external recorded file had more room to play with?
