Pros	Open weights under a permissive research/commercial license (with regional restrictions), unusual for a frontier-tier video model Strong motion coherence and prompt adherence, competitive with Runway Gen-3 and Kling in public evaluations Multimodal LLM text encoder handles longer, more descriptive prompts better than CLIP/T5-based peers First-class ComfyUI and Diffusers integration, plus official Docker and Gradio interfaces Supports image-to-video, LoRA fine-tuning, and multiple aspect ratios out of the box Free to self-host if you own the hardware, with no per-second generation cost	Pro editing timeline Best-in-class control (motion brush, etc.) Used in real productions Generation + editing in one tool
Cons	Requires a 60-80GB GPU (H100/A100) for 720p generation; consumer cards need aggressive quantization or offloading Standard clip length is only ~5 seconds (129 frames) per generation; longer scenes need stitching Hosted Tencent product is primarily targeted at mainland China users and can be awkward to sign up for from abroad License carves out large-user commercial deployment and some regional uses; read the terms before shipping Ecosystem is younger than Runway/Pika, so tooling for shot planning, cameras, and character consistency is thinner	Expensive for hobby use Render times can be long
