So it obviously was also trans-coded by Youtube.
Jeremy See is using Davinci video editor, it has more professional options for audio.
I have no proof, but my first guess is that it doesn't matter much which particular software package that he uses. It is the choice of sample rates and codec parameters that influences it the most.
For your video you've used 48kHz sampling rate during editing, so it was forcibly re-sampled twice:
- Yamaha outputs 44.1kHz, while your editor software wanted 48kHz
- Youtube again limited it down to CD-quality from DVD quality
I doubt this re-sampling is the sole reason, but it may be a contributing factor.
The other issue is that Jeremy See for sure is a "Youtube upload partner" with special privileges and capabilities available during upload. I have no intention of forcing you to dox yourself, so this is just for possible consideration.
His videos are available in much wider variety of formats:

I'm sorry for dragging this subject away from music into the technicalities territory.
