Compared a few options

Evaluated this against two competitors. Where it wins: prompt-based scene control and lowers the barrier to video production. Where it lags: limited fine control compared to manual editing. On balance the feature set — especially automatic sound and audio synthesis — justifies the 4 stars for our use case.

Use it every day

Honestly didn't expect to like it this much. Image-to-video generation is exactly what I needed, and lowers the barrier to video production. I do wish generated sound may not always match creative intent, but I reach for it almost every day now and it just clicks.
