I am developing a POC for a HTML panel that controls After Effects from within Premiere Pro. It is made for editors and people who are somewhat familiar with PPro but not with AE.
I wrote some code that imports an AE comp into PPro, that must have the possibility to be altered after importing. I know this works with comps that are manually imported with "dynamic link".
I am able to control the AE items from within PPro using BridgeTalk, so making these changes is not the problem.
I found this function "app.project.importAEComps(pathOfContainingProject, arrayOfCompNames)" that imports an AE comp, (from PPro2018 onward) but this imported item is not dynamically linked to AE. I need to do a manual operation, such as "edit original". I'd love to do this from within the automation.
Without dynamic link, the changes made in AE are not visible in PPro, not even after saving the AE project and re-importing the comp. There seems to be some caching involved. I need to restart PPro entirely for the changes to become visible..
importAEcomp = function(pathName, compName)
{ //This function runs in the PPro jsx environment
var prj = app.project;
prj.importAEComps(pathName, [compName]);
var impItem = undefined;
for(var t=0;t<prj.rootItem.children.numItems;t++) {
var projItem = prj.rootItem.children;
if(projItem) {
var index = projItem.name.indexOf('/'); //Use the comp name part
if(index>0) { //Search the item with our comp name
if(projItem.name.substr(0,index)===compName) {
impItem = projItem; //Found!
break;
}
}
}
}
if(impItem) {
// impItem.refreshMedia(); //Does this activate the dynamic link? Nope!
var seq = app.project.activeSequence;
var vItems = seq.videoTracks.numTracks;
if(vItems>1) { //We need at least 2 video tracks. Add our comp to the topmost video layer
var vTrack = seq.videoTracks[vItems-1];
if(vTrack) {
vTrack.insertClip(impItem,0); //Add the item to topmost layer
}
}
}
}
