Does Kling 2.1 Pro support audio?

Kling 2.1 Pro does not have native audio. You can pair it with ElevenLabs voiceover generation for separate audio that gets merged with the video.

What aspect ratios are supported?

Kling 2.1 derives the aspect ratio from the input image, so it adapts to whatever format your creator image is in.

Should I use 2.1 Pro or 2.6?

If you need native audio and lip sync, use Kling 2.6. If you don't need audio or plan to add voiceover separately, Kling 2.1 Pro can be a cost-effective alternative.
