Evidence claims:
- [upstream_claim] Page shows WanPipeline, HunyuanVideoPipeline, LTXPipeline and CogVideoXPipeline examples with num_frames, guidance_scale, negative_prompt and LoRA loading. · source: https://huggingface.co/docs/diffusers/using-diffusers/text-img2vid
- [upstream_claim] Page says group offloading can lower a 14B Wan model's requirement to about 13 GB VRAM and warns quantization may affect video quality depending on the model. · source: https://huggingface.co/docs/diffusers/using-diffusers/text-img2vid
- [upstream_claim] Page notes some models need specific num_frames values, e.g. HunyuanVideo recommends (4 * num_frames) + 1. · source: https://huggingface.co/docs/diffusers/using-diffusers/text-img2vid
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
