Real-looking people in a product video, for $0, on a MacBook: I tested 5 methods

说明与用途

作者在 MacBook Pro M1 Max 上测试了五种免费本地方法，以在产品演示视频中添加逼真人物。最佳结果来自使用 SDXL 生成图像，每个镜头约 2 分钟即可在 GPU 上生成一致的角色。其他方法速度慢或质量不佳。

问题

Product demo videos lacked realistic human characters, relying on silhouettes or icons, which reduces viewer connection.

结果

AI images with SDXL delivered realistic, consistent characters in ~2 min per shot on the Mac GPU, outperforming free stock, AI video, Blender 3D, and talking narrator methods in speed and quality.

工作流

• Define a single character description and reuse it across all shots
• Generate two image options per shot with fixed seeds using SDXL
• Select best images manually
• Add slow camera push and overlay narration
• Render final video with HyperFrames at 1080p

证据

Everything ran on one MacBook Pro (M1 Max, 64 GB), cost $0, and used about 28 GB of models.

The winner is AI images with SDXL: realistic, consistent characters at ~2 min per shot on the Mac GPU.
