The only way I know to bypass the embedding is if you get the YouTube link straight from Google search.
For examples:
Sonic the HedgehogSonic by Blue Core Studios (CGI Sonic and various, live-action locations and humans.)
The Hedgehog by Chris Lee & Paul Storrie (Little to do with Sonic and more just about how depressing growing up is. The Eggman guy hangs himself.)
Sonic Boom the Musical by random Encounter (people wearing costumes, mostly a songs than a full movie)
Sonic the Musical by Random Encounters (Like the above video, but more of a parody trailer.)
End of Sonic Adventure by juicitron (Actors in costumes. Might have had a prequel but I can't find it. A sequel to another fanfilm called "
Sonic Adventure Unlimited" but can't find the sequel.)
Sonic the Hedgehog! by Ninja Kidz
Sonic: Chaos Conquest by Brunch Boiz Productions
Return to Little Planet 2 by The Sonic Show (There is a Part 1 and Part 3 but I can't seem to find them.)
I know there are other live-action Sonic videos out there but I chose ones that I figured were more significant and of interest. There were few more videos I really wanted to add to the list but I couldn't find them on YouTube. They were either taken down or lost in YouTubes search algorithm.
Streets of RageStreets of Rage/Bare Knuckles Fan Film by Team Chaotix Br
Bare Knuckle Streets of Rage &
Part 2 by Basil Masters
Streets of Rage by Dogger StreetStupid (More of just a series of brawls than an actual story)
De-Pixelatied - Streets of Rage by GameTrailers (Again, mostly just a series of brawls to emulate the game)
Fran Campos Films are making a Streets of rage fan film.
OtherHouse of the Dead by Ian Adams (It really is the only THotD fanfilm I can find.)
Shenmue: 'Suka High by Rising Tiger Films (Live-action, with dialogue from the games.)
Ryo Vs Lan Di | Shenmue Live Action Martial Arts Fan Film by Fred Nguyan Khan
Kiwami | Yakuza by Red Phoenix Films
EDIT: OK, nevermind. The forum removed most of the google search links. Eitherway you can add these fanfilms on the list if you want, and any live-action fanfilms you know of.
