Hakol Timer countdown timer sent as an NDI source

A clean video source, over the network

The timer is rendered off-screen and sent as NDI frames, so it does not depend on a spare monitor output. Resolution and frame rate are configurable, and the source name is yours to set, so it is easy to find in a busy NDI list.

Alpha channel for keying

Turn on the transparent background and the NDI stream carries a real alpha channel. Lay the countdown straight over your programme, a lower third or an LED wall layout in Resolume or vMix — no chroma key needed.

Where it is used

Live streams — show a "starting soon" countdown or the session timer in OBS or vMix.
LED walls — map the timer into Resolume Arena alongside the rest of the content.
IMAG and broadcast — give the director a timer source for the multiview.
Hybrid events — the same timer on stage, on the stream and on remote presenters' screens.

One timer, all outputs

NDI runs alongside the full-screen output window and the browser viewer, all showing the same countdown in any of the five styles: digits, ring, bar, dots or flip clock. Control it from a Stream Deck or over OSC.
