Kling 4.0 vs Kling 3.0
Kuaishou's newest video model against Kling 3.0: sound always on, a cinematic format, a different price.
The short answer.
Kling 4.0 is Kuaishou's newer video model. In Aventada it always makes sound with the picture and adds a cinematic 21:9 format; Kling 3.0 lets you switch sound off. Both make clips of 3 to 15 seconds in 720p or 1080p.
Per second at 720p with sound, Kling 4.0 costs 37 credits and Kling 3.0 21. Kling 3.0 costs less again with sound off.
Pick Kling 4.0 if…
- Long takes that hold together from start to finish.
