A Redditor shares an experimental long-form video made with H3 using T2VA: a retro 70s/80s-style character with no image anchor, so she shifts slightly at invisible seams. Specs: int8 quantization, 32 steps, 1344x768, roughly 7 hours to render, with decoding peaking at 192/192GB of RAM. The character mouths the tune during non-singing parts since the prompt didn't prevent it. Author shares takeaways and asks for feedback on the film grain and period feel.
