TF2: Poor Heavy... Horrible...
The video itself could have been done by complete ameatures. Get SleepNWake Tool, get Henry's Animation Tool, learn how to hide the HUD, and never EVER use first person perspective AGAIN, unless you're parodying gameplay (which reminds me, if you wanna do that, get TF2 sweps. Mmkay? Mmkay). Now remember kids, your addons folder is found in C:\Program Files\Steam\Steamapps\<username>\garr ysmod\garrysmod\addons. Good day ameature.
Oh yeah and dat resolution.
