How much does it cost?

It depends on the model and the settings, and the exact price is on the Generate button before you start. The lowest here is Seedance 2.0 Mini: from 0.5 credits per second. A clip that fails costs nothing: its credits come back automatically.

Can I try it for free?

Yes. The free plan gives 10 credits every month with no card, enough for 20 seconds of video in clips of up to 15 seconds with Seedance 2.0 Mini.

Is there a watermark?

No. RenderHour adds no watermark to results, on the free plan or any other.

Can I post the videos on TikTok?

Yes, within the model makers’ terms and our Terms of Service. TikTok asks creators to label realistic AI-generated content, so switch on its AI-generated label when you post.

Every video model here makes vertical 9:16 clips for TikTok, Instagram Reels and YouTube Shorts, from a prompt or from a photo as the first frame. Kling 3.0, Seedance 2.5 and Veo 3.1 can make the sound with the picture. RenderHour adds no watermark, on the free plan or any other.

How it works

Open the Video page with Kling 3.0 picked and choose 9:16 under Aspect ratio.
Describe the scene, or add a vertical photo as the first frame (from a photo, some models keep its shape), and pick a length.
The price is on the Generate button. Generate.
Download the clip and post it, or put several together in your editor.

Tips

Show the most striking moment in the first second: that is when viewers decide to stay.
Keep the subject in the middle of the frame, away from where the app puts its buttons.
Add captions and text in your editor: models are not reliable at writing words.
