Just a tiny micropost here to help add some information that was missing from the internet.
I was trying to find a video or tutorial that would show me how to upload horizontal videos to Instagram stories. I could not find a solution that did not require downloading apps or editing things on my computer. After watching one lengthy tutorial, I realised* this can be done very simply on your phone in a matter of seconds.
Here is how you do it:
- Shoot an amazing video holding your phone properly (horizontal)
- Open the video using Google photos
- Click the edit icon
- Rotate the video left or right 90 degrees (your choice)
- Upload to Instagram
*Apparently the voice-to-text dictation app on my phone is British.
