Magisto supports the following orientations and aspect ratios:
1) Landscape - 16:9 (1920×1080, 1280×720, etc.)
2) Portrait - 3:4 (1536×2048, 1440×1920, etc.)
3) Portrait - 9:16 (1080x1920, 720x1280, etc.)
4) Square - 1:1 (1080x1080, 720x720, etc.)
Magisto automatically sets your video's orientation based on the majority of your photos and video clips (51% of your footage). A landscape video will be created if 51% of your selected raw footage is landscape.
With the Professional and Business upgrades, you can manually select the video orientation during the creation (website, mobile) and the editing (website, mobile) process.
