Kling V4.0 Text-to-Video: Text to Video Online
Bottom line
Kling 4.0 Text-to-Video: one 3-30 second shot with native audio, 720p or 1080p, from 35 credits. Type a prompt into the Text to Video tool and Kling V4.0 Text-to-Video renders it on VdoBloom credits — the cost is shown before you commit, and no Kling API key is needed.
Kling 4.0 is Kuaishou's newest video model, launched on 15 October 2026, and its headline change is length: a single generation can run up to 30 seconds, so a long continuous shot no longer has to be stitched from short clips. On VdoBloom the text-to-video version takes a prompt of your scene and returns a clip with native audio generated in the same pass.
You choose 3, 5, 8, 10, 12, 15, 20, 25 or 30 seconds, 720p or 1080p, and a 16:9, 9:16, 1:1 or 21:9 frame. Pricing is per second: 11.4 credits at 720p and 17 credits at 1080p, so a 5-second 720p clip is 57 credits and a full 30-second 1080p take is 510. The exact cost is shown before you generate, and a failed job is refunded automatically.
Use it when the shot itself needs time to breathe: a walk-and-talk, a slow reveal, an aerial drift. For a few seconds of action, a shorter and cheaper model usually does the same job.
