I'm surprised that I don't find any sort of Report This link (or Edit page link) on https://www.imdb.com/title/tt0048445/videogallery or on the trailer itself. (And, yeah, it's The Sound of Music trailer).
And when I try the Edit Page button on the main title page, I can't find the trailer under Trailers or Video Clips (no existing data).
So this is a dual report: a bad video, and no contribution way to report it.
Thanks for reporting the Video tag error, the video has now been corrected to the correct title tag and the change should be live on the site shortly.
If you find any future video content on the site that is linked to an incorrect title or name, please report this to our staff using this form then following the path IMDb Fan/Contributor questions > Images & Video > Report videos.
