Thank you for reaching out to help me I was having trouble getting the skin spotlights to work but if league director works fine that's great to hear.
No sweat. The Skin Spotlights tool is great but it hasn't aged well, IMO the League Director is better on almost all fronts.
I also needed help to know if you can use replays in your the replays folder. Thanks again for your help!
I haven't opened any of those replay files myself, I usually do everything in the moment. So if I get a cool clip or something I'll save the replay and get the shots I need in that short period of time. It's probably not the best way to do it, but it works for me.
If you want to learn how to open the old replay files, I think this method still works: https://boards.na.leagueoflegends.com/en/c/miscellaneous/nFFznEqK-how-do-i-open-rofl-replay-files?comment=0003
If you need a super specific shot you can easily recreate it yourself rather than playing a full PvP match or custom game. This is what I do (like when I did those Yasuo shots in the Blood Moon: Rising video)
1 - Create a Practice Tool match
2 - Do the action (example being Blitzcrank casting his ult near dragon pit) To be safe, do it a few times to make sure you get the right shot!
3 - Win the game by taking the nexus or pressing the "Win the Game" option. **If you don't do this, you cannot save the replay of the game. **
4 - Save the replay at the end of the game or by using your match history.
5 - Open up the replay and the League Director to start playing around with the camera tool.
edit: And here's a Rioter saying pretty much the same thing about playing old replay files:
