Make that just flat: Flaat is my brand of flat and I don't think I'll be releasing a different Flaat without slog2
And also: I just uploaded a video where I did something very wrong, and I think the "fix it in post" thing kind of worked. It's the first thing I shot with the a7s, a couple of months back. I had the camera, I had my new 40mm pancake lens, and it was a friend's wedding, in a very nice location. But my new ND filters didn't arrive on time. All I could do was adapt my 67mm filters for the tiny pancake, which made the camera small-no-more, or... shoot with high shutter speed (up to 1/8000s) and then try to fix it in post, with the per-pixel-motion-blur filter of Adobe CC. I think it worked great, you can check the results here (yes, that's a gay wedding, I hope it doesn't offend anybody) (also: yes, I went for a very strong grade, using Mojo and Quick Looks):
So, the motion blur can be added in post with relatively good results. The problem is: the workflow is awful. The filter is very slow, and it doesn't recognize the cuts automatically, so you have to give it the original files (I tried to apply it over the final edit and it created artifacts around the cuts, just like warp stabilizer BTW). I went for an overnight initial transcode-and-add-motion-blur, then replaced the source files, and exported again.
Sorry about the use of your "flaat" trademark, but actually i really like your flaat profile, so my initial point still stands, what would be the "flaatest" picture profile below 3200?
I really don't wanna go the "fix it in post" way, i'm pretty sure that might work for some people, for me it won't, so any picture profile that looks like yours below 3200 would be just great.
Other than Slog-2 cinegamma4 is the next flattest gamma profile and it can be used down to iso 100. It is not in a PP by default so you will have to make a custom one. I saw settings for cinegamma4 at some point but don't recall where.
I will try cine gamma 4, as for the ND recommendation I guess it's good for when you have the proper time for changing nd's through your lenses but for docu/travel type of projects it just doesn't work for me.
We just shot a short film where we shot 50 % of the time outdoors. As I wanted to shoot at ISO100 with a reasonable room for correction, I did my tests and ended up with "PP off, Standard, -3,0,-2". This gives you a gamma response that is very close to BMDFilm4k, aka a log format that is not as flat as S-Log.
If you want to use S-Log as well, you can create a picture profile with S-Log2 gamma, Movie colors and +4 Sat. With this you can match your shots easily.
