# screenlapse

No frills NodeJS based timelapse screen recording CLI util, largely thanks to

[screenshot-desktop](https://github.com/bencevans/screenshot-desktop). Records

screenshots as image sequence w/ configurable interval.

```bash

git clone https://github.com/postspectacular/screenlapse

cd screenlapse

yarn install

# start recording, ctrl+c to stop

./screenlapse.js  

```

All args are optional, but must be given in this order:

-   `` - number of milliseconds between each recorded frame (default: 500)

-   `` - start frame number (default: 0)

## Editing the image sequence

Since each recorded frame is stored as separate JPG file, removing

unwanted frames is easy. However, the missing frames cause the image

sequence to be interrupted in terms of consecutive numbering and

`ffmpeg` will stop encoding at the first gap. To avoid this, use the

included `batch-rename` bash script to rename / renumber all images like

that:

```bash

./batch-rename *.jpg

```

## Build mp4

```bash

ffmpeg -r 12 -i '%04d.jpg' -vf scale=1920:-1 -movflags faststart -c:v libx264 -preset slow -crf 18 -y recording.mp4

```
