AI Video System Creates Life-Sized Projections of Deceased Loved Ones

A developer has constructed a personalized home system titled ‘Solaris no Madobe’ (Window of Solaris) that uses generative AI to create life-sized video projections of a deceased loved one. The system operates while the user sleeps, utilizing high-performance hardware including RTX 5090 and 4090 GPUs.

The technical architecture integrates the MiniMax H3 open-source video generation model, the Krea 2 image generation model, and Large Language Models such as Qwen 3.8 27B. The system generates new images via LoRA training and converts them into short video clips. These clips are displayed on vertical high-definition displays to simulate a life-sized presence.

The developer detailed specific technical challenges, such as optimizing framing to ensure the subject appears at a natural scale and managing video loops. To avoid the unnatural movement caused by reverse-playback loops, the system now utilizes a sequence of forward-playing clips to maintain visual continuity.
