Increase 4K resolution temporal layers to 6

stickz1 requested to merge stickz1/SVT-AV1:increase-4k-speed into master

Description

This merge request increases the encoding speed of 4K content by 20%. An additional 2GB of system memory is used. Tested on an i7-14700k with Mode 2 & 3. This is the difference between full and partial CPU saturation for 4K content.

By default, content with a source resolution of 4K or higher is encoded with 5 temporal layers. This is problematic because it greatly reduces the CPU parallelization benefits of SVT-AV1. This merge request raises that threshold to 8K content for faster encoding speeds.
