Chroma subsampling artifact GoPro VR player

by BrandonBlizard » Tue Oct 17, 2017 2:45 am

I am experiencing severe chroma subsampling artifacts when viewing stereo panoramas, that do not appear when viewing with other player software. It is very exaggerated when viewing through a headset. Is there a way I can reduce this effect? Or is there an alternative player that is as convenient as the GoPro player?

Maybe it is due to runtime resizing by GoPro VR Player, it occurs when the image is too big to fit in 1 texture (according to graphic card capabilities).

What is the size, in pixels, of your image ?

I have tried 1024x1024 to 4096x4096 (stereo) on a pair of Titan X's
Here are screen shots from 1k 2k and 4k. The artifact is clearly visible in all cases, but most grievous in lower resolutions.
