Tactics for summarization of long documents

I have been playing around with the different chains and wondering with the advent of longer context windows if there might be other strategies one could use?

I am specifically looking to do elif-style comprehensive summaries of longer pieces like transcripts from podcasts and youttube videos.

I came across this: Summarize Podcast Transcripts and Long Texts Better with NLP and AI | by Isaac Tham | May, 2023 | Towards Data Science

Are there other techniques out there? Papers, etc?

Thanks in advance!

What a wonderful time to be alive!
