Wan 2.1 is Alibaba Cloud’s open-source video generation suite that makes short clips from text or image prompts where it is multilingual and supports Chinese or English!
Using a VAE and diffusion transformer (DiT), it creates cinematic visuals that look real af.
How it works
You launch a text prompt (up to ~800 chars) or image upload, choose the aspect ratio/resolution; then the magic begins!
The T2V-1.3B runs on consumer GPUs (~8.2 GB VRAM) where it takes around 4 min for a 5-sec 480p clip.
The larger 14B models produce higher fidelity visuals (up to 720p) with complex movements and fluid transitions.

Works on consumer GPUs super efficient and accessible.
Fully open-sourced: code
Cons
If you’re using public hosting to generate text-to-video content, it may take ~10 mins and ~15 mins for image to-video per clip.
The watermark of the rendering is shown when using public hosting.
This tool has difficulty with moving camera shots, and consistency between characters can wobble.
Conclusion
So, Wan 2.1 is a great AI video generation tool that gets deep roots in video editing keywords, with cinematic pattern, motion simulation, and multilingual overlays.
