It can happen if your video originally was made in horizontal/landscape mode. Currently, Prequel offers vertical formats only.
But we're happy to share a little secret with you — our team is currently working on introducing additional canvas formats to give you more creative freedom.
Our team is always trying to bring some fresh features that would satisfy the requests of all our users! So, if you have more ideas, feel free to share them with us – you can do it here in the app via Contact us button or email us at support@prequelapp.com.
We're always excited to hear from you :)
