After downloading a PNG, import it in this edition’s Picture workshop to assign it to a map and world. Keep the original video separately; this preview does not store it.

VIDEO POSTER WORKSHOP

Loading the video poster workshop…

Inspect your own video, choose a time and capture its picture. This preview does not save assignments, stories or game data.

Local source

Up to 64 MiB, 120 seconds and 1920 × 1080. Larger sources need deliberate preparation elsewhere. Video stays muted and is never played here.

No video inspected.

Playback range

This chooses when a victory story starts and stops. It keeps the complete original video and does not reduce the package bytes.

Choose and inspect a video first.

Optional physical trim, resize and compression

Choose a bounded output plan. FPV / LINE checks the exported hash, decoded duration, exact output dimensions and codec, audio tracks, and fresh start/end frame comparisons before offering a download.

Choose and inspect a video first.

Converter support has not been checked. The pinned converter loads only after you ask; the supported slice is one silent browser-decodable MP4 or WebM video track, exported as AVC/H.264 MP4.

No transformed video has been produced. Playback range keeps the complete original video.

Tab/arrows and Enter navigate. Controller South edits the selected field or slider; D-pad changes it, South confirms and East cancels. Choose a source opens bundled examples and current assets. New device files use the browser or operating system chooser. Escape cancels work or returns to Workshop.

What the timestamps mean

The requested time asks the browser to seek. An observed frame timestamp comes from its decoded-frame callback and can differ. Without that callback, the preview labels an approximate playhead and unavailable frame timestamp. Neither value promises arbitrary frame-number accuracy. Downloaded PNG bytes are the actual captured picture.

Frame stepping appears only after the browser reports a presented-frame timestamp. The tool repeats bounded seeks until that timestamp changes; it never invents a frame rate. A browser may skip more than one frame, so review the observed timestamp and PNG. Browsers without that callback keep these controls disabled.
