# Alan Swift Concurrency for Swift 6 (Part-1)

Hello! This is Alan.

I checked the contents of this Swift Concurrency (Part-1) lecture from time to time, and I noticed that the lecture video was not in sync (the lecture screen and voice were slightly behind each other..?) while playing..ㅠ
(I don't know exactly what the cause is thoughㅠ)

So, I changed the codec and encoding method and replaced all the lecture files uploaded to Infraon. I hope you don't experience any inconvenience!
(If this problem occurs again, please let me know anytime🙏🏻)

Have a nice weekend!

Thank you. :)
