I thought I would recode it, but later I realized YouTube has multiple streams with differing quality.

You can do something like:
$ youtube-dl 'https://youtube.com/watch?v=m7XZmugtLv4‘ -F
(output compressed manually here for brevity, there are even more streams and you should match audio and video stream of the same type - either webm+webm or m4a+mp4, otherwise the resulting file will be unplayable in web browsers)
format code  extension  resolution note
250          webm       audio only tiny   73k , opus @ 70k (48000Hz), 8.38MiB
251          webm       audio only tiny  142k , opus @160k (48000Hz), 15.14MiB
243          webm       640x360    360p  450k , vp9, 30fps, video only, 34.46MiB
244          webm       854x480    480p  867k , vp9, 30fps, video only, 61.47MiB
247          webm       1280x720   720p 1866k , vp9, 30fps, video only, 128.83MiB
248          webm       1920x1080  1080p 2887k , vp9, 30fps, video only, 226.14MiB

I chose audio "251" and video "244", so I executed the following command:
$ youtube-dl 'https://youtube.com/watch?v=m7XZmugtLv4‘ -f 244+251

Moments later:
[ffmpeg] Merging formats into "PART 1 - CNN Insider Blows Whistle on Network President Jeff Zucker’s Personal Vendetta Against POTUS-m7XZmugtLv4.webm"
...and I uploaded the 77M file.

Btw. it supports much more than youtube.
