Trying to adjust inPoint of a layer
I am editing some old VHS videos that were put onto DVD. There are sections that need to be removed. I have created a simple dialog with buttons to simplify editing. One button successfully splits a layer then reverses the order so that the extra layer is below the original. I then move forward to the point where the extra layer needs to split and the section deleted. eg. at 10 seconds the footage becomes static, I split and reorder it there. At 15 seconds the static ends.
How do I split the layer, delete the 10-15 second section and move the next section of the footage back to the outPoint of the layer above?
What I have so far is this:
splitAdjust.onClick = function() {
var myComp = app.project.activeItem;
var selectedLayer = myComp.selectedLayers;
var currLayerIndex = selectedLayer[0].index;
var delLayerIndex = currLayerIndex + 1;
var prevLayer = myComp.layer(currLayerIndex – 1);
var fadePoint = prevLayer.outPoint;
if (selectedLayer.length > 0){
app.executeCommand(app.findMenuCommandId(“Split Layer”));
app.project.activeItem.layer(delLayerIndex).remove();
app.project.activeItem.time = fadePoint;
app.project.activeItem.layer(currLayerIndex);
myComp.layer(currLayerIndex).inPoint = fadePoint;
}else{
alert (“No layers selected.”);
}
}
Hopefully someone can help!

I think I would try not to use any menu commands, if possible. So I’d try a workflow like this: you drop a marker layer at one end of the area you want to cut out and move the CTI (current time indicator) to the other end, and run a function like this (which you could attach to your button):
function splitAdjust(){
var myComp = app.project.activeItem;
if (!(myComp && (myComp instanceof CompItem))){
alert ("No comp selected.");
return;
}
if (! (myComp.selectedLayers.length > 0)){
alert("No layer selected.");
return;
}
var myLayer = myComp.selectedLayers[0];
if (! (myLayer.property("Marker").numKeys > 0)){
alert("Selected layer has no marker.");
return;
}
var compTime = myComp.time;
var markerTime = myLayer.property("Marker").keyTime(1);
myDup = myLayer.duplicate();
myDup.moveAfter(myLayer);
if (markerTime < compTime){
var t1 = markerTime;
var t2 = compTime;
}else{
var t1 = compTime;
var t2 = markerTime;
}
myLayer.outPoint = t1;
myDup.inPoint = t2;
myDup.startTime -= t2-t1;
myLayer.property("Marker").removeKey(1);
myDup.property("Marker").removeKey(1);
}
splitAdjust(); -
Thank you @danebberts! That works perfectly.
I have included an Add marker button on my dialog.
Can you tell me what the command is to move to the next/previous marker is?

You generally access a marker by its key index, like this:
property("Marker").key(1)or by time, like this:
property("Marker").nearestKeyIndex(myComp.time) -
Thank you for solving this, Dan!
