Can smaller number of frames be generated as output?

[nnsriram27]

I was wondering if it's possible to generate fewer than 121 frames as output. When I tried setting num_video_frames=9 in the inference script, I got an error. Then I modified chunk_duration=9 in registry.py, which did produce a video, but it was still around 3 seconds long and the quality seemed lower compared to using chunk_duration=121.

I have a couple of questions:

1. Is it possible for the model to generate a different number of output frames, particularly fewer frames at a lower FPS?
2. Even when I set both chunk_duration=9 and --num_video_frames=9, the output video is still ~3 seconds long. What determines the minimum duration or number of frames the model can generate?
