How to turn a long video into Reels

Questions
Which shape should I use for Reels?
9:16. If you're posting to the feed instead, use 4:5: it's the tallest shape the feed shows without cropping.
Can I post the same clip on Facebook?
Yes. A 9:16 clip works on Facebook Reels as it is, and 4:5 suits Facebook's feed.
Will Instagram's buttons cover the captions?
No. nine16 places captions clear of the buttons and text Reels lays over your video.
Can I change where a clip starts or ends?
Yes. Move the start or end by a few seconds and render it again. Re-cuts are free.
Do I need the rights to the video?
Yes. Only clip videos you own or have permission to use and repost.
