AI video generation guide
TL;DR
KrafLayer supports text-to-video and image-to-video AI generation with Sora 2, Kling, and Seedance 2.0 — generate video clips from prompts or reference images in your browser.
Quick answer
An AI video generator creates short clips from text prompts or reference images. KrafLayer supports both text-to-video and image-to-video workflows, helping users choose models such as Sora 2, Kling, and Seedance based on quality, speed, duration, and credit cost.
What is an AI video generator?
An AI video generator creates short video clips from text prompts or reference images. KrafLayer runs multiple video models — Sora 2, Kling O3, and Seedance 2.0 — so you can pick the right balance of quality, speed, and cost for each project.
- Text-to-video: describe a scene and the AI generates a video clip with motion, lighting, and camera movement.
- Image-to-video: upload a still image and add motion — the AI animates it while preserving the original composition.
- Multiple duration options depending on model: 5-second quick clips to 10+ second sequences.
- No software install — generate video directly in the browser.
- All generated videos are saved to your personal gallery for download.
How does text-to-video AI work?
Text-to-video models generate video frames from a text description. The model interprets subject, motion, environment, and camera direction from your prompt. Stronger prompts with explicit motion cues produce more stable, intentional clips.
- Describe subject motion first: walks, turns, reaches, looks up.
- Add secondary motion: hair in wind, dust drifts, fabric ripples.
- Specify camera motion if needed: slow push-in, pan right, locked-off.
- Keep it simple — one clear action per 5-second clip works better than stacking multiple events.
What is image-to-video AI?
Image-to-video takes a reference image as the starting frame and generates motion from it. The AI preserves the composition, subject, and lighting of your image while adding movement. This is ideal for animating product shots, illustrations, or photos.
Which AI video generator is the best?
It depends on your priorities. Sora 2 produces high-quality cinematic output. Kling O3 offers Pro and Standard quality tiers. Seedance 2.0 is the current Seedance lane to compare first, while Seedance v1.5 Fast remains useful for lower-cost iteration. KrafLayer lets you compare all three without switching platforms.
How much does AI video generation cost?
KrafLayer video models charge per generated second. Costs vary by model — Seedance v1.5 Fast is the most affordable, while Seedance 2.0, Sora 2, and Kling Pro cover the more premium tiers. Check the generation cost page for exact credit rates.
