Marker duration triggers scale
Hi,
I d’like to zoom a video multiples times during the duration of markers along the timeline.
One zoom at 120% and another 140%.
When the markers are over the scale goes back to 100%
It is not necessary to use linear or ease transition.
Here is an example.
Thank you for your help.

Hi Jean,
try this as an expression for scale of the layer:
(function getZoomFromMarker() {
if (!marker.numKeys) return [100, 100];
nk = marker.nearestKey(time);
nki = nk.time > time ? nk.index - 1 : nk.index;
if (nki == 0) return [100, 100];
m = marker.key(nki);
markerEndTime = m.time + m.duration;
if (time > markerEndTime) return [100, 100];
zoomFactor = parseFloat(m.comment.split(" ")[1]);
return [zoomFactor, zoomFactor];;
})();
