Episode 1 · Grok Video Generation Tested: Up to 15 Seconds (2026-07-31, 2 posts)

Users tested xAI's Grok Imagine video generation feature, praising its high realism and ease of use. The tool can currently generate videos up to 15 seconds long with minimal censorship on facial content.

Episode 2 · xAI's Imagine Video 1.5 Upgrade: Native 1080p and Text-to-Video (2026-08-01, 9 posts)

xAI's video generation model Imagine Video 1.5 has received a major upgrade, rolling out across its API and consumer products, alongside an integration with Runway. The update introduces text-to-video capabilities, omni-reference inputs, and native 1080p output, significantly improving dynamic realism and audio fidelity.

Confirmed

  • Core Feature Upgrades: Imagine Video 1.5 adds text-to-video generation, allowing users to create videos directly from prompts without a starting image. It also introduces an omni-reference model supporting both image and audio inputs.
  • Resolution and Quality: The new version supports up to native 1080p resolution output, building on previous improvements to deliver more realistic motion and sound.
  • Multi-Platform Rollout: The model is now fully available on xAI's API and consumer-facing products.
  • Runway Integration: Runway officially announced that Grok Imagine Video 1.5 is accessible directly within its platform.

Why it matters

  • This update rounds out xAI's video generation capabilities by adding text-to-video and multimodal reference inputs, while the native 1080p output significantly boosts overall quality and competitiveness.
  • Opening the API and integrating with major third-party creative platforms like Runway will greatly expand its creator ecosystem and commercial use cases.

Episode 3 · Grok Imagine introduces consistent characters for video (2026-08-01, 2 posts)

xAI's Grok Imagine has introduced a consistent characters feature, allowing users to maintain a uniform character appearance across different generated video scenes to tell cohesive visual stories.

Episode 4 · Grok Imagine Four-Skill Automated Short Film Workflow (2026-08-02, 5 posts)

Author @tetsuoai shares a complete automated workflow for creating AI short films with Grok Imagine. The workflow chains four custom commands (skills) to solve consistency challenges and achieve high automation from text to video prompts.

Confirmed

  • Workflow overview: The short film production can be completed through four core skills. The creator only needs to input a one-sentence premise, and the system automatically writes a script, then generates character images, scene and prop images, and finally outputs detailed video prompts.
  • Character consistency: Using the /imagine-char-sheet command, combined with character portraits and script descriptions, locked character three-view images (front, back, portrait) are generated, maintaining character consistency in videos.
  • Scene and prop consistency: Using the /imagine-location-prop command, descriptions are directly extracted from the script to generate clean reference images.
  • Prompt creation: The final step uses the /imagine-prompt-creator command. Inputting script beats and required reference image tags (e.g., character, scene) automatically generates detailed video prompts.

Why it matters

This workflow significantly lowers the barrier to AI video creation. Through standardized command combinations, creators can systematically solve the long-standing inconsistency issues of characters, scenes, and props in AI video production, turning complex short film creation into an efficient pipeline.
