I am developing for a custom headset and I am having issues with the camera preview. When I enabled passthrough I see vertical banding on the image which looks to be possibly shutter related. We have noticed this issue in various camera related apps, but it looks like changing the resolution can fix it in some cases. Is there a way to change the camera resolution via this API? I tried changing between the speed and quality optimizations, but no luck. Also, when I run the example script to poll the fields I don't get any plain strings, just things like android.colorCorrection.gains, android.colorCorrection.mode, etc.

Hi,
Thanks for the suggestion

That's what I figured. Just
That's what I figured. Just wanted to see if it was something that had been observed before. One last question. When I dump the image properties through GetVideoMode inside of Unity I see the format as 64 for both optimizations. What do that actually mean?
Hi,
Hi,
My understanding is that its corresponds to this enum values: https://library.vuforia.com/sites/default/files/references/unity/namespaceVuforia.html#a8f7511b96bcb33bc2ea176a1a8dafb59 and 64 is NV12.
To have an overview the output from GetVideoMode are as follows:
