Why choose Kling5 AI
Kling5 AI keeps the page, examples, generation path, and pricing focused on Kling 5 so creators can move from idea to video with fewer distractions.
Kling 4.0 at a glance
Choose duration, frames, references, resolution, and aspect ratio to fit each shot.
3–30 seconds, set by the second
Pick any length from 3 to 30 seconds, so one generation can hold a long single take instead of several stitched clips.
Text to video
Describe the scene, subject action, and camera movement in text to generate a paced video clip.
First and last frame
Upload a first frame, and optionally a last frame, to control where the shot starts and where it lands.
Reference images and videos
Reference to video accepts up to 10 images and 5 videos, so you can carry a character, product, or motion style into a new shot.
720p and 1080p
Test ideas at 720p, then switch to 1080p for the final cut. Credits scale with resolution and duration.
Four aspect ratios
Text to video and reference to video support 16:9, 9:16, 1:1, and 21:9. Image to video follows the uploaded frames.

Tips for working with Kling 4.0
Common approaches to planning long takes, organizing references, and choosing resolution.
PL
Planning long takes
3–30 seconds
For longer clips, describe the shot in time order, such as the opening, the main action, and the closing frame, so the pacing stays clear from start to finish.
DurationStoryboard
3–30 seconds
OR
Organizing references
Reference to video
Say in your prompt what each reference image or video is for, such as the character, the product, or the camera movement. Results tend to match your intent more closely.
ReferencesConsistency

CR
Choosing resolution
720p–1080p
Validate the idea with 720p and a shorter duration first, then generate the full 1080p version once the direction is set.

How long can a Kling 4.0 video be?
+
Any length from 3 to 30 seconds, chosen by the second.
Which generation modes and references are supported?
+
Text to video, image to video with a first frame and an optional last frame, and reference to video with up to 10 images and 5 videos. Reference videos need to be at least 3 seconds each and 30 seconds in total.
Which resolutions and aspect ratios are supported?
+
Choose 720p or 1080p. Text to video and reference to video support 16:9, 9:16, 1:1, and 21:9; image to video follows the uploaded frames.
How are credits calculated?
+
Credits depend on duration and resolution. When you add reference videos, a lower per-second rate applies, and the billed seconds include the output plus the longer of the reference videos or the output. The Generate button shows the exact credits before you start, and credits for failed generations are returned automatically.
How is Kling 4.0 different from Kling 3.0?
+
On Kling5 AI, Kling 4.0 supports up to 30 seconds (Kling 3.0 supports 15), reference to video with images and videos, and the 21:9 aspect ratio. Kling 3.0 still offers motion control and a sound on/off option. You can switch between them in the same generator.
