When to pick Grok Imagine Video
The catalog brackets Grok Imagine Video at 65 credits per generation — 13 models cost less, 8 cost more. The ~60s / 5s clip turnaround suits deliberate work — worth the wait when the result is final, wasteful for throwaway drafts. Clips run 3-15s, up to 15 seconds. It generates synchronized audio natively, so the clip ships with sound rather than needing a separate pass. Its catalog tags read native audio, dialogue & sfx, creative modes — the areas where it outperforms general-purpose picks. Reach for Grok Imagine Video when native audio matters most and you would rather not manage a separate xAI subscription to get it.
When to look elsewhere
When cost is the deciding factor, Wan 3.0 Prime at 60 credits undercuts Grok Imagine Video by 5 credits per generation. When you are iterating rather than finishing, Seedance 2.0 Mini returns a clip in ~20s / 5s clip versus ~60s / 5s clip — the faster loop usually wins the draft phase. If a single uninterrupted shot longer than 15 seconds is the requirement, Aleph 2 reaches 30 seconds.
