using @microsoftuk windows 10, @google takeout and movie maker 10 to download, rotate and re-upload your @youtube videos #windows10 #youtube #video #download
windows 10 has a video editing app confusing called "Photos" but the rotate button is disabled when you are editing videos

google youtube does NOT let you download videos unless you pay for youtube premium ( or they are your own)
you can use google takeout to download all you youtube videos and separate meta info in JSON files
- https://takeout.google.com/settings/takeout/custom/youtube
- https://takeout.google.com/settings/takeout/downloads?pli=1
you can also use youtube studio to download your youtube videos one by one
but
- you can only download 1 video at a time (5 videos in 24 hours)
once you have downloaded your videos you can download and run movie maker 10
download movie maker 10
run movie maker 10
- click rotate video button,
- choose your video,
- choose your rotation then
- save it

you can now re-upload the rotated version to youtube

here are my rotated videos
