A7RII excessive noise at 6400 Video

[garychanchan]

Trying to figure out why I'm getting lots of noise when shooting video at 6400 ISO using crop mode.

 

All the testing I can find online suggests I shouldnt be getting this. Any ideas?

 

Crop mode, 6400 ISO, PP4 Cine4 Cinema. Also tried changing settings in picture profile but noise was still there.

Link to pictures/examples? Haven't touched PP4, I use no profile, or PP7/Slog2.

Figured it out. Was shooting in HD mode. Once I changed to 4k the noise was almost all gone.

Interesting, so HD had increased noise? That's not something I would have imagined. Only tried shooting 4k and 720p @120fps.

so here are screenshots from A7rII in HD mode iso 3200-4000. Why is there so much noise in HD mode?

 

Shooting with Tokina 11-16mm, cinema, cine4

I haven't tried Cine4 (I would stick to no PP/normal or PP7, personally). Those images still look underexposed, so I would imagine that noise performance might actually improve if you move up to ISO6400 and push some more of the data out of the noise floor. I agree that these are very bleh, but I think it is a combination of exposure and the picture profile, not the camera itself.
