Well, on a 64gb card, Prores HQ gives med 40 min and RAW 3:1 gives me 36 min.
I don't really change shutter speed, I set it for 172 or 180 depending on 24/25 fps. And when i shoot raw i don't really fiddle with that either, gust go between 5400 for daylight and 3200 for artificial light. I bought the video assist because it was real cheap, but i do miss waveform and false color a lot! Buying the Gratical eye soon for that but then there's the battery issue where the setup goes more "traditional handheld" which i prefer anyway.
Are you talking about the shots in the club? I didn't do much, exposed and pointed the camera, you know;)
