Analog Clock for OBS Studio or vMix

AnalogClock is a plain HTML/CSS/JS Browser Source layer for OBS Studio or vMix for displaying a classical analog clock based timer. This is usually used as a count-down until an event starts or as a duration for a pause.

A centrally deployed version of AnalogClock is available under the URL https://rse.github.io/analogclock/.

1. Add your Browser Source source to OBS Studio:

   • Local File: (disabled)
   • URL: https://rse.github.io/analogclock/?options
   • Width: 1920 (or whatever is your stream resolution width)
   • Height: 1080 (or whatever is your stream resolution height)
   • Use custom frame rate: (disabled)
   • Control audio via OBS: (disabled)
   • Custom CSS: (empty)
   • Shutdown source when not visible: (enabled)
   • Refresh browser when scene becomes active: (enabled)

   Or add your Web Browser input to vMix:

   • URL: https://rse.github.io/analogclock/?options
   • Width: 1920 (or whatever is your stream resolution width)
   • Height: 1080 (or whatever is your stream resolution height)

1. Install Node.js and Git.

2. Clone the AnalogClock sources:
   git clone --depth 1 https://github.com/rse/analogclock
cd analogclock
   

3. Download all dependencies:
   $ npm install

4. Add your Browser Source source to OBS Studio:

   • Local File: (disabled)
   • URL: local-path/analogclock/index.html?options
   • Width: 1920 (or whatever is your stream resolution width)
   • Height: 1080 (or whatever is your stream resolution height)
   • Use custom frame rate: (disabled)
   • Control audio via OBS: (disabled)
   • Custom CSS: (empty)
   • Shutdown source when not visible: (enabled)
   • Refresh browser when scene becomes active: (enabled)

   Or add your Web Browser input to vMix:

   • URL: file://local-path/analogclock/index.html?options
   • Width: 1920 (or whatever is your stream resolution width)
   • Height: 1080 (or whatever is your stream resolution height)

• until=iso-time (duration for segment display until time in ISO format YYYY-MM-DDTHH:MM:SS, default: none)
• duration=minutes (duration for segment display in 1-60 minutes, default: none)
• fraction=minutes (fraction in minutes to round up duration, default: none)
• autostop (whether to automatically stop clock when timer ended, default: none)

Hint: if either option duration or until are given, the clock with show a done/todo-segment and automatically shuts down once the ending time is reached.

• size=size (width/height of clock in pixels or percentage, default: 100%)
• opacity=number (amount of opacity of clock in 0.0-1.0 range, default: 1.0)

• background0=color (canvas background color, default: transparent)
• background1=color (outer border color, default: #555555)
• background2=color (inner background color, default: #f0f0f0)
• background3=color (soft attention overlay color, default: #ffcc66)
• background4=color (hard attention overlay color, default: #ff6666)
• ticks=color (color of ticks, default: #333333)
• digits=color (color of digits, default: #666666)
• pointer1=color (color of hour pointer, default: #000000)
• pointer2=color (color of minute pointer, default: #222222)
• pointer3=color (color of second pointer, default: #cc0000)
• segment1=color (outer color of done segment display, default: #b06820)
• segment2=color (inner color of done segment display, default: #f4dbc2)
• segment3=color (outer color of todo segment display, default: #2068b0)
• segment4=color (inner color of todo segment display, default: #c2dbf4)
• segment5=color (outer color of overrun segment display, default: #c03000)
• segment6=color (inner color of overrun segment display, default: #ff6030)

• lang=iso-cc (language as ISO country-code for voice messages, default: en)
• overrun (whether to draw overrun segment, default: false)
• silent (whether to avoid any voice messages or sounds, default: false)
• moving (whether to move/fly in clock initially, default: true)

For interactively controlling AnalogClock press:

• duration-based timer of (N x 10) + M minutes:
  d N M (N = 0 ... 5, M = 0 ... 9)
• until-based timer to (N x 10) + M minute:
  u N M (N = 0 ... 5, M = 0 ... 9)
• termination of timer:
  x
• manual attention via N times clock flashing:
  a N s (N = 1 ... 9, soft/orange) or
  a N h (N = 1 ... 9, hard/red)
• manual voice hints:
  h s (slower)
  h f (faster)
  h m (message)

Alternatively, instead of running AnalogClock as a standalone application, it can also be run on top of Head-Up-Display Server (HUDS). The advantage is that instead of having to interactively control AnalogClock, it can be remote controlled through HTTP and MQTT.

For this, run HUDS with AnalogClock with:

npx huds -a 0.0.0.0 -p 9999 -d analogclock:index-huds.html,index-huds.yaml

And then use the following URL for rending AnalogClock in OBS Studio or vMix:

https://localhost:9999/analogclock/

Finally, use the following URLs with HTTP GET requests for remote controlling AnalogClock from e.g. Stream Deck, Companion, CentralControl or ShowCockpit:

• https://localhost:9999/analogclock/event/duration.N (N = 0...59)
• https://localhost:9999/analogclock/event/until.N (N = 0...59)
• https://localhost:9999/analogclock/event/attention.N.type (N = 1...9, type = soft or hard)
• https://localhost:9999/analogclock/event/terminate
• https://localhost:9999/analogclock/event/hint.slower
• https://localhost:9999/analogclock/event/hint.faster
• https://localhost:9999/analogclock/event/hint.message
