    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

  2. I'm a big user of insta360 cameras, I have 2 of them, mostly to film myself and sometimes I use for projects too.... looking and some side by side the 1inch is definitely a step forward. I do agree that 8k would be the bar minimum.... I think the industry stays away from 8k as stitching 8k video would probably only be possible on top-of-the-line phones and PCs.... and the market that they target it is mostly consumers. Same for requiring higher speed microSD 8k, 400 Mbits, 10 bit LOG would be the quantum leap that is needed to have 360 cameras used more professionally All screen shoots from videos:
