Aspect ratio (AI video)
The width-to-height ratio of a generated video. 9:16 for vertical, 16:9 for horizontal, 1:1 for square.
Aspect ratio is the ratio between a video's width and its height. The three most common in AI video: 9:16 (vertical — for TikTok, Reels, Shorts), 16:9 (horizontal — for YouTube, landing pages), and 1:1 (square — for some Instagram feed posts). Generating at the wrong aspect ratio and cropping in post loses resolution and composition; better to generate in the target aspect ratio. VIBE supports all three in the prompt screen.
