1What the notes say
xAI's API release notes say little about video, and say it plainly. Video generation opened on 28 January 2026, the Batch API took video jobs from 15 March, and grok-imagine-video-1.5 added reference-to-video with preset voices and native 1080p on 31 July 2026. Runway's changelog records the 1.5 model reaching its MCP thirteen days later, at 1 to 15 seconds with audio.

7Where new versions end up
Release notes such as “Grok Imagine” matter once a pipeline runs the models; SceneMixer's guides describe how it does:
The Seedance 2.0 tiers render segments up to 15 seconds; use a Seedance 2.5 or Wan tier for 30-second takes.
SceneMixer, Seedance 2.0 Fast — “Does Fast render 30-second takes?” (read 2026-10-13)
AI dubbing replaces the audio of a finished clip and then tries to match the lips. Native-language generation gives the video model the line in the target language before the shot exists, so mouth movement, pauses and shot length are produced for that language.
