generate_video produced no frames

Error message

generate_video produced no frames

What it means

Video generation completed but produced zero frames. Guard: check frame count after generation and report an internal error instead of muxing an empty video.

Solutions

1. Check earlier log lines for frame-generation errors.
2. Verify the video model loaded correctly and parameters (num frames, resolution) are valid.
3. Ensure sufficient memory/VRAM to generate frames.
