                 **Generation Modes:**
-                - **Fast Mode (up to 210s GPU budget)**: Fixed 10 denoising steps for quick generation. Suitable for single-person videos or quick previews. The 210s is the maximum GPU allocation time, not the actual generation time. **For free-tier users: Fast mode can generate approximately 6 seconds of two-person video at most; longer videos may timeout.**
-                - **Quality Mode (up to 720s GPU budget)**: Custom denoising steps (adjustable via "Diffusion steps" slider). Recommended for multi-person videos that require higher quality. The 720s is the maximum GPU allocation time, not the actual generation time. With 40 denoising steps, approximately 10 seconds of video can be generated.
