I can't open your video (the first link). Looks like you pasted wrong link (for editing and not watching). Also it is meaningless to troubleshoot such thing through youtube because it will reencode all what you send to it so you can't be sure that problem is not due youtube reencoding or see how real encoding looks like.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
This is a recording I made using bandicam and the x264vfw codec set. All information is within the video.
