By PulseAugur Editorial · [1 sources] ·

A user on Reddit shared their experience using the HunyuanVideo 1.5 model for an image-to-video project, specifically for a wedding video. They encountered significant performance issues when attempting to render at 1080p resolution on their NVIDIA 4090 GPU, with rendering times increasing substantially. The user ultimately utilized a more powerful 96GB card on HyperAI for the final renders, noting that seeds did not carry over, requiring them to re-select takes. AI
