Kling 2.1 — Frequently Asked Questions
How much does Kling 2.1 cost?
A 5-second Kling 2.1 generation costs 34 credits. The exact figure is shown on the Generate button before you spend anything, and a failed run refunds automatically.
How long can a Kling 2.1 video be?
Kling 2.1 handles up to 10 seconds in a single pass — selectable lengths are 5s and 10s. For longer pieces, generate several shots and cut them together in the editor.
Does Kling 2.1 generate sound?
No. Kling 2.1 outputs silent video. Add narration or music afterwards with the text-to-speech tool, or pick a model with native audio such as Veo 3.1, Kling 3.0 or Seedance 2.0.
Can I animate my own image with Kling 2.1?
Yes. Upload a still and Kling 2.1 animates it, and you can supply an end frame to control where the shot finishes. Image-to-video generally gives you far more control over composition than describing the same scene in words.
What resolution does Kling 2.1 output?
480p, 720p and 1080p. Anything you generate can be pushed to 4K afterwards with the video upscaler.
Can Kling 2.1 make vertical video for TikTok and Reels?
Yes — Kling 2.1 supports 16:9 and 9:16, so you can generate natively vertical 9:16 footage rather than cropping a landscape render.
Do my credits expire?
No. Unused credits expire at plan renewal/expiration. There is no throttled "unlimited" tier and no queue that slows down the more you use it — you see the price of each generation and pay that.
