Aspect Ratios and Social Export Guide
Choosing the ratio before you generate avoids cropping, letterboxing, and re-rendering later.
Pick the ratio first
CineGen generates in 16:9 landscape, 9:16 vertical, and 1:1 square, with 4:3, 3:4, and 21:9 also available.
Deciding the destination before you generate means the composition is framed correctly from the start.
Which ratio for which platform
Use 16:9 for YouTube and site banners, 9:16 for TikTok, Reels, and Shorts, and 1:1 for feed placements and marketplace listings.
If one concept needs to run across several channels, generate it once per ratio rather than cropping a single export.
How resolution affects credits
Costs are charged per second and scaled by resolution: 480p is 1x, 720p is 2x, and 1080p is 5x. The aspect ratio itself does not change the price.
A common workflow is to test the concept at 480p, then re-render the final version at 1080p. Free accounts can generate up to 720p.
Aspect ratio FAQ
Can I change the ratio after generating?
No. The ratio is set when you generate, so render again in the ratio you need.
Which ratio is best for TikTok?
9:16 vertical fills the screen on TikTok, Reels, and Shorts without cropping.
Does a larger ratio cost more credits?
No. Credits depend on clip length and resolution, not the aspect ratio.
What is the highest resolution available?
Pro and Lifetime plans can generate at 1080p. Free accounts generate at up to 720p.
