Which is cheaper, Kling 3 or LTX 2?
LTX 2 costs less per generation at current plan rates. Exact cost depends on clip length and resolution — see the cost table above.
Can I use both Kling 3 and LTX 2 on one account?
Yes. Both are available on Pixel Engine from the same credit balance, so you can switch between them without a second subscription.
Which one generates audio?
Kling 3 generates native audio with the video. The other produces silent video that you would need to score separately.
Can I animate an existing image?
Both models support image-to-video, so you can supply a still frame as the starting point rather than generating from text alone.
