i prefer not to put myself out on the internet because it just seems unsafe. although i use my real name, i do so as a courtesy to seem authentic. i dont have any video to share but i can offer my process to learning a song that is not mine.
i normally just learn other peoples material, but my approach is i start out with the song and start at 50% speed or lower depending on how fast the song. if i am really digging the song i can probably churn through the memorization in about a week, maybe less.
this means each day i play through the song slowed up a few times through following along with the tab, i turn my tv vertical, hdmi my laptop, hit ctrl+alt+left arrow to rotate the screen, pull up the tablature, hit play on music speed changer web app setting speed to like 40ish percent. i have gotten quite decent at turning pages, its not that hard really at slower speed, especially if the lick is cool and unique enough you have some leeway when to turn the page because some licks just seem easier to memorize very quickly. i do this for a few days, eventually i can just play it without the tab, this is when i can start to increase the tempo. i just keep working it up as far as i can get it until i top out. i can get them even faster the more i play em, but the plateau happens and to go beyond it means i have to play it everyday for life.
i prefer a complete song as it just seems more complete to me to be able to play something rather than pieces of something. although somethings are challening and you have to break them into pieces, but eventually i would use the above as the process to try to finalize it into a complete picture.
on the side i kinda tool around in loops of licks or create my own licks. i have two song ideas churning, but no melodies to kind of finalize them. oh and i try to soundslice things every now and then to keep my notation skills up to date, or to help memorize licks i come up with because you will forget so always notate them. fretboard manuscript paper is highly recommended for licks that you might be having problems seeing with your minds eye that way you can see the entire lick on the fretboard and the location of it. heres an online one i found so you wont need paper.

theres other areas i got into as well like when i learn i piece i try to break into the chord progressions, analyze the melodies and licks to see what soundscape they reside in. work on rhythm, learn more chords.
now if you really want to be courageous you can learn a piece all by ear which i have only done once, you must put on your monk outfit because this requires some extreme patience. it will teach you about audiation though which is something that every musician should try to work on. but i would say try to learn about 5-10 songs first before doing this so you at least have some sounds flowing in your mind.
