Video Narrative
Play a video full screen, draw on it, and export the result.
Media
Nothing here yet. Drop a video or an image anywhere on this page,
or copy one into the videos/ folder and hit Refresh.
Script
NoneLoad a bookmark script here and it is applied — chapters and referenced media included — the moment you press Start.

Audio
OffVideo audio applies to both what you hear and what is recorded. Narration is mixed in as one track, and is never played back through your speakers, so there is no feedback loop.

What this is
Video Narrative turns a silent screen recording into a narrated walkthrough, in one take, in your browser. You play the footage full screen, talk over it, circle things with a marker, and press one key to export a YouTube-ready MP4. Nothing is uploaded anywhere — everything stays on this machine.
The five-minute version
- Drop your recording into the
videos/folder (or onto this page), and pick it above. - Load a script (optional): a small JSON file that pre-marks the beats of your narration — the chapters, what to say during each, and any images or audio to cut to. Choose one from
scripts/or open one from disk; it applies the moment you press Start. - Start, then press R to record. Everything you say, draw and zoom is captured; none of the panels are.
- Walk the beats: G plays your chapters in order, N moves to the next one. Segments on a photo always wait for you.
- Stop with R again — the MP4 downloads automatically.
The script format, in one glance
{
"version": 2,
"media": [{ "name": "map.png", "kind": "image", "src": "/videos/map.png" }],
"bookmarks": [
{ "label": "Intro", "srcStart": 0, "srcEnd": 46,
"note": "What to say here",
"actions": [{ "at": "0:10", "do": "pause" }] },
{ "label": "Show the map", "media": "map.png", "fade": 0.8,
"note": "Stills hold until you press N" },
{ "label": "Back", "srcStart": 49, "srcEnd": 55,
"actions": [{ "after": 5, "do": "goto", "to": 1 }] }
]
}
Times are 0:25, 1:02:03 or plain seconds. srcStart/srcEnd
are positions in the footage; start/end may hold a composed timeline.
Actions: pause, resume, next, goto — at an absolute
time ("at": "1:07") or relative to the previous action ("after": 25).
