garychanchan Posted August 19, 2015 Share Posted August 19, 2015 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.

FDP Posted August 19, 2015 Share Posted August 19, 2015 Link to pictures/examples? Haven't touched PP4, I use no profile, or PP7/Slog2. Link to post Share on other sites More sharing options...
garychanchan Posted August 20, 2015 Author Share Posted August 20, 2015 Figured it out. Was shooting in HD mode. Once I changed to 4k the noise was almost all gone. NamarBurton 1 Link to post Share on other sites More sharing options...
FDP Posted August 20, 2015 Share Posted August 20, 2015 Interesting, so HD had increased noise? That's not something I would have imagined. Only tried shooting 4k and 720p @120fps. Link to post Share on other sites More sharing options...
garychanchan Posted September 6, 2015 Author Share Posted September 6, 2015 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 http://2yuk.com/sample/iso3200.png http://2yuk.com/sample/iso4000_.png are other people getting similar results? thanks!

FDP Posted September 7, 2015 Share Posted September 7, 2015 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. Link to post Share on other sites More sharing options...
