[HELP] MP4 can't encode with PCM, but why this MP4 file can?

[ssdde]

it's worth when you research to find out the truth, maybe you will learn something more to improve Hybrid

That file is not an .mp4 file.
That file is a .mov file, that someone renamed if it has a .mp4 extension.

Format profile                : QuickTime

is a dead giveaway.

so if i encode x264+PCM with mov in Hybrid, i can get a .mov file, then i can change the extension name to .mp4 directly, to achieve the goal?

and another question, can all these tracks could be muxed by Hybrid to get one single best audio track?
