PixVerse AI provides you with the option to choose from multiple aspect ratios, including the standard 16:9 widescreen format, 9:16 vertical or portrait format, 1:1 square format, and 4:5 format for Instagram.

4. Video Duration

A longer video duration can save you a lot of time and effort you would otherwise invest in manually editing and stitching multiple video clips.

Hailuo AI can generate high-quality videos of up to 6 to 10 seconds, with a restriction of 6 seconds for higher resolution in some versions.

Upon free access, Kling AI can create videos of 4 to 5 seconds. The AI video generation model supports a maximum video duration of 2 minutes, which is included in only paid subscription plans. It also comes with an ‘Extend’ feature that lets you add 4 to 5 more seconds to the video, but the total length can’t exceed 3 minutes.

Wan AI can produce videos of up to 10 seconds, and some AI video generation models and versions support video lengths of 5 to 6 seconds.

Sora AI supports video duration of up to 25 seconds in the Sora storyboard, which is available only for pro users. The standard plans support a video duration of 15 seconds.

Google Veo, including Veo 3.1, can generate videos with an 8-second duration cap. However, it comes with an ‘extend’ feature that lets you add 5 to 6-second-long scenes to the existing video, extending the total length to up to a minute.

PixVerse AI can produce high-quality short-form videos, with a maximum video duration of 8 seconds. It can also create shorter videos of 5 seconds. However, the 1080p resolution doesn’t allow for a video length of 8 seconds. You can use the built-in ‘Extend’ feature to create longer videos of up to 30 seconds.
