I'm pretty sure some clips to show short pieces of historical film come under the education fair use. I have set myself up as an accredited library now. Similar clips have been on youtube for years and have not had takedowns.
If the mods want to remove the clip, feel free, but I found some of the sunflower scene etc. in an old dropbox account if anyone is interested.
A warning to everyone (mostly Americans) that some may find the deleted Fantasia scenes offensive or uncomfortable, if so, please have that discussion in a separate thread, I'd like to keep this about the preservation, not the politics.
