Veo 3.1 vs Grok Imagine
Google Veo 3.1 and xAI Grok Imagine compared on price, clip length, resolution, aspect ratio and audio — both on one credit balance at DubVoice.ai.
Short answer
Pick Veo 3.1 when the clip has to sound like something — it is the only model here that renders synchronised dialogue and effects with the picture, and it is the only one that reaches 1080p. Pick Grok Imagine when length, framing or budget decides it: 15 seconds is nearly twice any Veo clip, five aspect ratios cover formats Veo cannot, and a 6-second 480p clip costs 3,000 credits against Veo Fast at 7,500. A common split is to draft in Grok and render the final shot in Veo.
These are the two video models most people end up choosing between, and they are good at opposite things. The short version: Veo 3.1 gives you the better picture and its own soundtrack; Grok Imagine gives you longer clips, more aspect ratios and a much lower bill.
Both run on the same credit balance, so this is a question of fit rather than commitment — there is no second subscription involved in using each where it wins.
