> Expanded video resolution reference, usage limit enforcement with grace periods, specialist agent cards in AI chat, and composer length selector.

<Update label="2026-03-31" tags={["Improvements"]}>
  ## Expanded video resolution reference

  The [video resolution reference](/features/composer#video-resolution-reference) in the composer docs now includes per-platform frame rate ranges, minimum resolution thresholds, codec requirements, and the Instagram Reels 25 Mbps bitrate cap. Use these tables to verify your video meets all requirements before publishing.

  ## Usage limit enforcement

  When you reach a plan limit for posts, AI images, videos, or reels, the system now follows a clear enforcement flow: you receive a warning notification, get a 72-hour grace period to upgrade, and only after the grace period expires are the affected features suspended. Upgrading restores access immediately. See [plans and billing](/account/plans-and-billing#what-happens-when-you-exceed-a-limit) for details.

  ## Specialist agent details in AI chat

  The [AI chat assistant](/features/ai-chat) now identifies each specialist agent by name and role when delegating complex tasks. Expandable cards display the **Growth Strategist**, **Creative Agent**, **Content Optimizer**, **Publisher**, and **Integrator** with their focus areas, so you can see exactly which agent is handling each part of your request and what functions it is calling.

  ## Composer length selector

  When using the [composer](/features/composer) inside the workspace view, the assist panel now includes a **length selector** alongside the tone selector. Choose **Short**, **Medium**, or **Long** to control how much text the AI generates when you use the **AI Write** tool. The guided content builder also offers the same length options in its advanced settings. See [post composer — caption length selector](/features/composer#caption-length-selector) for details.

  ## Default video provider changed to Hedra

  The default video generation provider is now **Hedra**. Previously, generating a video without explicitly selecting a provider could route the request to Runway. This fix ensures the behavior matches the documented default. If you prefer Runway, you can still select it manually in the **Advanced options** panel of the [video generator](/features/ai-content-generation#video-generation).
