Choose by the job, not the model name
Start with the output you need. If synchronized sound is central to the idea, Veo 3.1 and MiniMax H3 include native audio, while Kling 3.0 and Seedance 2.0 let you decide whether to generate it. Wan 2.7 is a visual-only workflow, which can be useful when narration, music, and sound design will be added during editing.
Resolution should follow the stage of the project. Kling 3.0 is the only model in this comparison with a 4K option, while MiniMax H3 reaches 2K. Veo 3.1, Wan 2.7, and Seedance 2.0 provide 1080P options. Lower resolution is usually the more efficient place to test composition and motion before refining a selected direction.
Format matters before generation. Veo 3.1 focuses on landscape and vertical output. Kling 3.0 adds square framing. Wan 2.7 and Seedance 2.0 provide more editorial and social formats, while MiniMax H3 also supports cinematic 21:9. For image-to-video workflows, the uploaded image may determine or constrain the frame.
