The independent kling4pro.com service is designed for creators who want watermark-free MP4 exports, 16:9, 9:16, and 1:1 framing, lip-sync audio, and multi-shot direction, with free credits for new accounts.

Kling 4.0 Preview adds 30-second native clips, an experimental 120-second mode, Omni Reference for consistent characters and props, and synced multilingual audio. Kling4.org provides access as the rollout expands.
