What is Aspect Ratio in AI Video?
The proportional relationship between width and height of AI-generated video. Different platforms and use cases require different aspect ratios.
How it works
Aspect ratio determines the shape of your output video. Common ratios include 16:9 (landscape, standard for YouTube and web), 9:16 (portrait, standard for TikTok, Reels, and Shorts), 1:1 (square, Instagram feed), and 4:5 (Instagram portrait). When generating AI video, you need to specify the target aspect ratio before generation because it affects composition, subject framing, and overall visual balance. Most tools support multiple aspect ratios, but the quality and composition can vary between ratios. For multi-platform campaigns, professional studios often generate in 16:9 for maximum quality and reframe or crop for other platforms, or generate separately for each target ratio.
