Aspect Ratio and Resolution

What aspect ratio means

Aspect ratio is the shape of the output.

Use it to match where the result will be used:

• 9:16 for TikTok, Reels, Shorts, and vertical ads
• 16:9 for YouTube-style horizontal videos
• 1:1 for square posts or product tests
• 4:5 for feed-style vertical images

What resolution means

Resolution is the output size and detail level.

Higher resolution can look better, but it may cost more credits or take longer. For early tests, use a normal setting first. Increase resolution after the idea works.

Keep a workflow consistent

Use the same aspect ratio across related nodes.

If a product demo starts in 9:16, keep the image, video, and composer output vertical unless you are making a separate version.
