🙏🙏🙏 Scream for help to Ukraine 🇺🇦

This alert created by company based in Ukraine from shelter.

24 February 2022, Russia started bombing cities with peacefully civilized population in whole Ukraine. Breaking the laws of war. Their bombs has been killing children and adults. This deserves Hague court.

🏠 If you are from Russia, please stop your government by any means including protests, don't trust local media, they are bribed by the government. They always was. I am sure you already feel lie by unexplainable crazy things in your country caused by world sanctions.

💣 Please spread the information about bombing of Ukraine in all social way you could. Russia treacherously broke into the territory of a sovereign state. Do not trust to anything from Russian media, most likely it will be bullshit

💼 If you have any kind of business cooperation with Russia, please block it now and keep most of money on your side, this is the only possible ethical decision

☢️ Ask your government to stop Russia from spreading invasion in any way. Russia is nuclear threat to the whole world. You think it is not possible? We thought that bombing of independent country with population of 44.13 million is also not possible.

Scriptimate – OpenSource svg animation tool

Create webm/mp4/gif videos by animating qualitative SVG files (e.g. exported from Figma or any other vector image editor).

⚠️ for now Supported Node version is 16+ (Probably 14, but 12 is not working)

Works on on 🪟Windows WSL 2 🐧Ubuntu 🍏Mac

Typical example

Create text file demo.smte:

set_frame_size 600 300
place boomerang 0 100
animate_1000 move boomerang 400 - && rotate boomerang 720 && scale boomerang 2

Place boomerang.svg into src/ folder. E.g. this one: boomerang.svg

Execute scriptimate to compile video:

npx scriptimate@latest -i demo.smte -f gif

You will get:

Read guide here

Prerequirements

You need to have next packages on your system (works for Ubuntu and Windows WSL2):

sudo apt install libnss3-dev libatk-bridge2.0-0 libcups2 libgtk-3-0 libgbm-dev ffmpeg

( All apart ffmpeg required to run pupeeter which is used to generate high-qaulity frames, some taken from here https://gist.github.com/winuxue/cfef08e2f5fe9dfc16a1d67a4ad38a01 )

Required version of ffmpeg >=4.x (Will be installed automatically in Ubuntu 20.04+, when in 18.04 it will be 3.x, which is not compatible)

If you are using custom changable texts, please make sure you have all fonts that you use in styles installed into OS, e.g. on Ubuntu:

sudo apt install fonts-roboto fonts-open-sans

Getting started

If you want to start using scriptimate, please read carefully these 2 posts:

How to run examples from this repo

Pull the repo
cd example
Execute npx scriptimate -i 1_helloworld.smte

.smte syntax

Please start with reading scriptimate getting started blog post. This reference could be used for advanced use-cases.

Supported commands:

place: Place part

Part is svg file which is basic part of animation. Filename should slug-compatible (latin, no spaces, etc). Also this filename is used as id of part anywhere

place <svg file name without .svg> <left cord> <top cord> <[optional] opcaity: 0-1> <[optional] scale> <[optional] whichBoxHoleToAdd> <[optional] dashOffset>

Example: Place cursor.svg at 400 120:

place cursor 400 120

place_div: place a div

Usecases:

dynamically change content of div via schedule_eval
appear some content on page

place_div <id of div (any slug)> <left cord> <top cord> <width> <height> <[optional] opcaity 0-1> <[optional] content of div> <[optional] whichBoxHoleToAdd>

place_boxhole: place boxhole

Boxhole is a rectangle zone on page which relatively places parts in it with hidden overflow (with ability to hide out of the box and then slide to zone)

place_boxhole <left cord> <top cord> <width> <height>

addstyle: add style to part or div

addstyle <svg name or id of div> <css styles without spaces, e.g.: "color:white;font-family:'OpenSans'">

moveToTop: move some part to top over all elements

moveToTop <svg name>

Example:

moveToTop cursor

schedule_eval: schedule running of JavaScript

schedule_eval <id of interval> <interval in ms> <javascript code>

Example:

# schedule_eval task_time 10 incr('task_time_secs', 2); if (+get('task_time_secs') >= 60) { incr('task_time_mins'); set('task_time_secs', 0)}

animate_xxx: apply animators during xxx milliseconds

You can pass one or multiple animators(via '&&'). If multiple animators are specified they will be executed in parallel

animate_<duration in ms> <animator 1> <[optional] mode> [args of animator 1]  && <animator 2> <[optional] mode> [args of animator 2] and so on

mode: could be one of:

linear (default)
easein
easeout
easeinout

Available animators:

pause : do nothing, just wait (sleep)

pause

Example: sleep for 3.5 seconds:

animate_3500 pause

move: move part

move <svg name> <[optional] mode> <target left> <target top>

scale: scale part

scale <svg name> <[optional] mode> <target scale factor> <scale origin>

<scale origin> is css transform-origin, could be e.g.

center (default)
top left
bottom right
etc

rotate: rotate part

rotate <svg name> <[optional] mode> <target rotate deg> <scale origin>

opacity: change part opacity

opacity <svg name> <[optional] mode> <target opacity 0 - 1>

dashoffset: change dash offset

Used to draw strokes. Added by @maxm123

dashoffset <svg name> <[optional] mode> <target dashoffset>

resize_div

Could be used to create animated bars. This animator only changes width and height css attributes, so div should have display:flex or something added via addstyle.

resize_div <div_name> <destination width> <destination height>

define_group: define group of commands

Could be used to define several parallel complex scenarious.

define_group <group name, slug compatable>:
  <command 1> command args
  <command 2> command args
  etc

Then run_groups_together should be used to start them

run_groups_together <group name 1> <group name 2> etc.

Example:

define_group scenario1:
  animate_1000 move easein boomerang1 270 -
  animate_2000 move easeout boomerang1 $frameW-$boomerang1__WIDTH $frameH-$boomerang1__HEIGHT


define_group scenario2:
  animate_1000 move boomerang2 250 -
  animate_1000 pause
  animate_1000 move boomerang2 $frameW-$boomerang1__WIDTH 0

define_group rotator:
  animate_3000 rotate boomerang1 360*4 && rotate boomerang2 360*5

run_groups_together scenario1 scenario2 rotator

Constants

Anywhere in smte you can define a constant with using:

const <slug compatible constant name>=<constant value>

Example:

const $PositionX=600 $underLocation=300

Built-in constants

When part is added there are internal constants

$<part name>__WIDTH    # width of SVG part in px
$<part name>__HEIGHT   # height of SVG part in px
$<part name>__LEFT     # current left coordinate of SVG part in px
$<part name>__TOP      # current top coordinate of SVG part in px

They return dimensions of SVG image.

Example. Place cake.svg and plate.svg directly under it:

place cake 0 0 
place plate 0 $cake__HEIGHT

Advanced ussage

Under the hood next commands are used:

ffmpeg -framerate 25/1 -i frames/%07d.jpg -c:v libx264 -r 25 out.mp4 -y

Or for webm:

ffmpeg -framerate 25/1 -i frames/%07d.jpg -c:v libvpx-vp9 -b:v 2M -r 25 out.webm -y

After generation phace we frames folder will be persisted so feel free to change ffmpeg command in any way you want to produce some exotic format.

CLI reference

After installing just use:

scriptimate -h

To show all available options.

  -nc NOCACHE, --nocache NOCACHE
                        Don't use screenshots cache (but still generate it), for scriptimate develeopmnt

Build performance

🪧 Scriptimate uses /tmp to store build cache, so to improve build speed even more, make sure /tmp is mounted on RAM in /etc/fstab

tmpfs /tmp tmpfs nosuid,nodev,noatime 0 0

⚠️ If you made changes out of project sources (e.g. updated sytem font and re-built video), and see there are no updates in results, please use no cache parameter (-nc 1)

Development

Just do:

npm ci
cd examples
node ../bin/scriptimate.js -i 7_dashoffset.smte -f gif

Known bugs and improvements

HTML Pages gen xx% shows more then 100% if run_groups_together is used. Only visual status bug, compiled video is correct
HTML pages generation process is not cached and not parallelized.
boxhole should be removed, instead we should specify div id and count relational coordinates from div
