Which online course is the best for learning QFT?

[Aidyan]

I'm looking for a good online introductory course in QFT for physiscists (i.e. at university level, for someone who already has the basics of CM, QM and relativity, but for one reason or another worked in completely different fields). I see there are several courses online, but it is not so easy to judge which is the best. Does someone has a suggestion?

The term "best" in this context is very subjective. David Tong's notes and videos are good,

I forgot to write: I mean *video* online course, where the professor elaborates on the blackboard or a presentation (e.g. on YouTube).

Yes, I know it is about a subjective impression, but sometimes a really good course obtains more thumbs up...

The stuff to which I linked has links both to written notes, and to video lectures.

Oliver Rosten has a nice set of lectures on the exact renormalization group.
