How this service works
Video scrub-bar storyboard: sprite sheets plus WebVTT thumbnail track (zip). Hover-preview thumbnails for a video player: sprite sheets capped at the device texture limit plus a WebVTT track whose cues use each frame's real timestamp, so they never drift. Handles phone rotation. Presets web_player, web_player_hd, mobile (WebP, 2048 cap), editor_filmstrip, contact_sheet.
Output
Returns a sprite sheet image (PNG grid of video frame thumbnails) and a WebVTT file that maps timecodes to tile coordinates, ready to plug into a video player's thumbnail preview track.
Example use cases
Video player scrub bar thumbnails
“I have a video file at https://cdn.example.com/course-intro.mp4 — can you generate a thumbnail sprite sheet for it with tiles every 5 seconds and a width of 120 pixels so I can add scrubber previews to my video player?”
Podcast episode video preview strip
“Generate a storyboard for this recorded podcast video at https://media.mypodcast.com/ep42.mp4, capturing a frame every 30 seconds at 160px wide, so I can show a preview strip on the episode page.”
Broadcast video quality check storyboard
“Create a storyboard sprite sheet from https://archive.broadcast.com/segment7.mp4 with the web_player preset, 1 tile every 15 seconds, and 240px tile width, so I can visually scan the whole segment quickly.”
