Sony a6400 HLG3 Footage Pixelations

Recommended Posts

Hi all,

So I've recently got the Sony a6400 specifically for video. Overall happy with it but recently been using the HLG picture profile(and also other PP such as CINE2), and I've noticed these pixelations on motion blurs(seen in the face/arm of subject), these blocks of pixels when they just just be regular motion blurs.

This shot was shot on 800 ISO,  and I just tried to move to create motion blurs. These aren't abrupt movements, they are just regular pans from left to right. 

I was wondering if anyone would know how to fix this, or would this be a SD Card issue or settings related. 


Gear used:

Sony a6400

Sony 18-105 f4

ISO 800

Sandisk Extreme Pro 1280gb  (170MBps) 


Thanks in advance,

    • Hi Pieter, Not yet. I've thought about that, to use a tripod. But I've no time to try that yet. I'll try it this weekend and let you know.  Thanks!
    • Did you try manually focussing at 135mm, camera on tripod / solid ground, delayed release? If you can get sharp pictures that way, at least you know the optics are fine.
    • I don't know how those cameras would fare as aviation cameras - either of them are far beyond my scope of purchase - but people have been taking pictures of planes and other man-made flying objects well, as long as they have been around.  Unless the aircraft is flying straight at you or flying perpendicularly away from you, the AF lagging behind the shutter should not be an issue and in almost all cases you would be shooting at infinity so internal lens movements to acquire focus should be at a minimum.  If you are expecting to crop a lot, I guess a camera with higher resolution would be better for you but that also depends on what you are going to do with the image.  If you are going to be printing large mural sized prints, higher resolution image would be better but if you are going to print at or below 11x17 or not print at all, even a cropped image from my A7II will be good enough on any consumer grade monitors on the market.  I have seen images printed from the first generation Olympus OM-D E-M5 (16MP) at 11x17 and they were excellent.
