Video prompt builder
Fill seven fields, get a text-to-video prompt in the structure Veo, Sora, Kling and Runway read best.
Script, shot list and prompt list
Paste a rough script; get timed beats, word count, a shot-list table, a storyboard JSON and one generation prompt per shot.
Prepare
Reference frames, image to prompt, aspect ratios and safe zones before generating or posting.
Image to prompt
Drop a reference image: palette, brightness, contrast, orientation and composition are read in the browser and written into a prompt skeleton for image-to-video.
Frame grabber
Pick frames from a video for a first-frame or a thumbnail: scrub, grab, compare on a contact sheet, download PNGs. The file never leaves your browser.
Safe-zone and aspect-ratio overlay
Drop a frame or a video and see the TikTok, Reels and Shorts UI zones over it; crop and pad numbers between 16:9, 9:16, 4:5 and 1:1 with the ffmpeg line.
Publish
Captions, thumbnails, platform presets, hooks.
Edit
Trim, split, convert, compress, extract: the file itself, in the browser.
