to version 13.6(AE), Encoder also don't render to H.264...Thanks
Read the details in the log file that you posted, especially the part toward the end about the Apple QuickTime H.264 component failing an computers with a large number of CPU threads.
You should never choose Quicktime H.264 as a rendering option because Apple has abandoned development of h.264 in the Quicktime container and is no longer developing it. It's always been a pain. Instead, use the Adobe Media Encoder's h.264 presets to render an MP4 which is compatible with all modern devices.
