The server used for testing had dual Intel Xeon E5-2687W v4 CPU’s set 3.50GHz, meaning 24 cores and 48 threads in total. The testing is using the constant quality option (crf) and the differences with different deadlines along with the cpu used parameter, these effect speed and the outcome quality. To see the encoding options for VP9 WebM with FFmpeg see my post here. Part 7 was both h264 and h265 (hevc) -deadline good compared to -deadline realtime. Part 6 was h265 with -deadline good compared to -deadline realtime. Part 3 was h264 with -deadline good compared to -deadline realtime. In this part 8 see FFmpeg comparison based on averages for encoding speed, fps, size and bitrate from both h265 (hevc) and h264 MP4 video file to VP9 WebM with grouping for the media type, deadline and cpu used values.
