Recommended filter settings for 4K sources about transform360

For 4K, the recommended setting is to make the cube_edge_length=1024. The cube length would be 1/4 * original_width, for 4K videos the original width is 4096, so we set cube edge length as 1024. As for why we use 1/4, you can read more in https://en.wikipedia.org/wiki/Cube_mapping, the original width should be the sum of the back, left, front, right faces.

The lower cube dimension will reduce the number of pixels thus bandwidth and achieve similar qualities as original.

That is great thanks for that. Closing. The compilation all works and encode works also.
