I often need to have a 4up video section with rather high end footage, 4K, 60p, 50Mbps source. This has always had significantly worse encode performance than I thought it should, compared to just a single track performance of the same footage and encode settings. A sample 4up display is shown in the attached pic with sample clips.

PD22 significantly outperforms PD21, a 30% reduction in encode time with NVENC and same settings between PD21 and PD22 with this 4up display configuration while the single track encode performance is nearly identical between PD21 and PD22. It appears PD22 maybe has better file I/O handling for these multiple streams for GPU or CPU encoding. The effect is very noticeable for high end streams, no real benefit for low quality sample clips.

PD22 is a lot slower loading the project to the timeline though, like 3X slower, with lots of “Not Responding” as the project loads and timeline is updated.
