Small issue at 'poles' when playing 180 stereo video

[charlesingea]

Describe the issue There is a tiny issue at the 'north and south poles' of an 180 video - a few pixels that stick out of the semisphere. It is not a big problem in itself but it messes up the feathering when using UnlitTransparent(stereo+color+fog+alpha) - it causes the feathering to be inconsistent at the north and south poles compared to the edges of the sphere.

Your Setup (please complete the following information):

• Unity version: 2022.3.46f1
• AVPro Video version (number and edition (trial/core/ultra/enterprise)): AVPro Video v3 - Ultra Edition
• Video specs (resolution, frame-rate, codec, file size): 8K side-by-side stereo, H265, 29.97 fps

Screenshots If applicable, add screenshots to help explain your problem. Without feathering:

With feathering:

Thank you! This has fixed the issue when no feathering is applied. But when I apply feathering, I still get this strange kind of artefact where the feathering at the poles is in this weird pattern: Do you know of any fix?

There often tends to be distortion at the poles. What you could do is use something like Blender to create a high-resolution UV Sphere (looking at around 128k verts) and that should improve it.

I see - thanks for the help!

@charlesingea You could also look to change the feathering better solve your use-case. You want to be looking at this line of code:

Maybe swapping it out for this line instead better works for your use-case?

float d = (uv.x - featherDirection.x) (uv.y - featherDirection.y) (featherDirection.z - uv.x) (featherDirection.w - uv.y) 10.0;

...and you end up with this kind of effefct:

We have fixed the 'notch' issue.

We have also changed the feathering code to the change documented above.
