Well, the first thing that's worth mentioning is that I got USB power bank that I can hang from my tripod in its little bag. Now I can shoot all day (from a tripod!) without changing battery or getting into rigging. So that's cool.
The other thing is that I had been shooting a bit in DR Boost in order to get extra highlight range and to help with shooting indoors in natural light. BUT! I noticed the midtones were quite noisy so I did a little investigation. I shot a step wedge (from +1 to -8 in whole stops) at various ISO levels, slapped on the VLog to V709 conversion and looked at where the noise is, in a bid to figure out whether I should be aiming to shoot at 250 or 2000DRB in general
Here is ISO 250 and it's a familiar noise pattern. Midtones are clean, shadows are a bit noisy:
Compare this to ISO 2000 with Dynamic Range Boost on:
The extreme shadows are cleaner up to around stop -4, where noise is similar to ISO 250. But from stop-3 all the way up to stop +1 this is clearly much noisier than ISO 250! It's noisy in the midtones and clean in the shadows. Weird! And it looks a bit weird when you see it in a real world clip.
For comparison's sake, here's ISO 2000 without DR Boost:
Right around the midtones, from stop -1 to +1 the regular old ISO 2000 is cleaner than with DR Boost. Below that point the shadows get noisier in a way we are used to seeing.
So what's the conclusion? Well, I use some colour treatments that really push visible noise a bit, especially chroma noise. If I'm going to shoot with DR Boost on I get some distracting looking midtone noise. It depends on the shot but sometimes it's really quite shitty looking. NeatVideo's temporal settings do a good job of cleaning it up, though. So my conclusion is that I'm going to start using a bit of noise reduction again, when I need it.
DR Boost is not simply "one stop extra in the highlights" and that's that. It comes at the cost of noise in the midtones.
PS: all shots were long GOP
