1What the task covers
Resizing a video changes its aspect ratio or dimensions, most often to move a horizontal cut to vertical or back.
Four makers keep a page for resizing video; others offer image resizers, which are not counted here. For a drama made for more than one platform, it decides whether one cut can serve both feeds.
Resizing is not reframing: a resized video may crop or pad the picture. The pages speak of fitting any platform; how the frame is recomposed is for each tool to show.
2Where the pages sit
Of the 4 pages, 2 under /tools/, 1 under /tool/ and 1 under /studio/. The path is the vendor's own site structure; a page under /tools/ or /make/ is usually a landing page for one job, while a page at the root is often a flagship product.
3In the makers' words
Adjust video dimensions for any platform, without losing quality.

4One maker's page for the task
One maker that keeps a page for work like “Resizing a video” is SceneMixer; here are its words, quoted as published:
Every segment starts with a short header that sets the stage before the first shot: Location (a scene chip), Time, Weather, the Opening frame (what the first frame shows), Set dressing (what is in the room, and any background people) and Props (the objects the segment uses).

It is applied when the script is read, so changing it means re-reading. Video already shot keeps the lines it was shot with.
