# Poster A published project opens with a cover slide built from the first shot's poster image. The image fills the background, a dark overlay dims it for legibility, and the project title, the publisher's avatar and name, plus a **Press play to watch.** instruction sit on top. Click anywhere on the cover to start playback. ## What it does The cover slide gives the audience a moment to see the project's hero framing and title before the sequence begins. It's automatic: whichever shot is first in the Sequence Timeline supplies the background image. Works whether the first shot is a still or a video; for video first shots, the poster frame of the video is used. The cover is interactive: * **Click anywhere on the cover to play.** Cursor changes to a custom play-icon while hovering. * **The action-bar play button pulses** while paused on the cover. The animation stops the moment playback starts. * **In comment mode, the cover shows a `not-allowed` cursor.** Comments attach to media slots only; the cover isn't a place for review feedback. * **Loop wraparounds skip the cover.** Once playback starts, looping returns to the first shot, not back to the cover. ## How the title is set The title comes from the **Title** field in the [Publish tab](/publish/publish-tab.md). It defaults to the project's name; override it for a client-facing title before publishing. Changing the title after publishing updates the cover on the next publish. ## When the first shot can't supply an image If the project is empty or the first shot's image fails to load, the cover falls back to a black background. The title, avatar, and "Press play to watch." instruction remain visible. This is rare in practice; usually a published project has a renderable first shot. ## Social link previews When the published link is shared in a social post, an email link card, or a chat preview, the unfurl renders as a generic Intangible icon plus the Studio link. There's no per-project preview image or thumbnail substituted into the card today. ## What's not supported * **No poster image upload.** The cover image is always the first shot's poster; you can't substitute an arbitrary image. Reorder shots to change which one fronts the cover. * **No per-project social preview image.** The unfurl is a generic Intangible card. * **No cover-only title slide option.** The cover is always the first shot's image plus title; there's no flow to suppress the image and show a black-background title slide. ## Related * [Publish tab](/publish/publish-tab.md) * [Presentation mode](/publish/presentation-mode.md) * [Export Video](/publish/export-video.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
