Hello. I use sony A6400 and noticed about some blocky artifacts when use 25fps andISO more than 3200 and object move quiclly. i used good transcend card 128gb v30 and this problem is not in low bitrate. I test some cases and discovered what this artifacts become on all PP besides SLOG2 and SLOG3 and only on 25,30,50,60 fps, not 100-120fps, ISO > 3200. Anybody has this problem or it's defect of my camera? This example includes settings: HLG1 4k 25fps, ISO 5000 https://yadi.sk/i/7GE68PqfjElfgQ

Hello there! watch video: https://www.youtube.com/watch?v=a4Up6AtNSlM (RAW FOOTAGE: https://we.tl/2dxvAk7i6I) I got the a7s for like 7 months now. And since day 1 I am struggling with noisy footage. After researching about different PP settings, exposures, grading. I still getting noise (also in daylight), even in my mid-tones. So some people advised me to go to the shop. So I went to the shop. And I told them about this problem. He asked which ISO I do shoot. I said between 800 - 1600/3200. And he answered that I have to shoot at 3200 for best quality. (I already did a lot of shots with 3200, but I thought that I give it 1 more try). But still had noisy footage. So I did this simple test with scopes from premiere. And what I see in my scopes is that in my mid-tones and shadows I see dancing pixels.(watch 0:25) You can see moving pixels in the black background, on the LED light controller (in the colored buttons, and the grey part) and also in the green parts of the mini cactus. I use a7s + 55mm 1.8 Zeiss. (+ Sony SDXC card 128gb 94mb/s) You guys are my last hope. I hope I have explained clear enough to understand for you guys.

Hey everyone, new to this forum and new to the world of Sony. I previously had a Canon 700D and just made the move to Sony mirrorless and bought the a6300. So far I'm loving shooting photos with this as I was just in the Faroe Islands and had some great shots with it; however, looking at the video footage I took in both 4k and 1080p, well most of it is absolutely 100% unusable. Every shot is loaded with aliasing and moire, it's unreal! I was not expecting this with this camera as I've heard wonderful things about the video on this camera. Anyone else have this problem and what can be done about it to prevent it and also to get rid of it in existing footage. Equipment and settings: Sony a6300 SanDisk Extreme Pro 95MB/s 64gb, class 10 SD card MC-11 Adapter with Sigma 17-50mm Lens (I know it's not 100% compatible!) Modes: XAVC S 4K 24fps - shutter 1/50th - Cine4 Profile XAVC S HD - 120fps - shutter 1/250th - cine4 Profile Conditions: Daylight Overcast/Clouds Water/lake (terrible aliasing) Patterns (jeans, beard, etc = aliasing/moire etc) Absolutely horrible experience with video...unusable. Anyone else having this issue or is my camera in general!? Thanks, Neil
