Is there a way or an api that would allow me to copy all the elements in a premiere pro sequence and append those elements to another premiere pro sequence?
Try running the following from ExtendScript Toolkit, with a project containing one sequence open.
var seq = app.project.sequences;
var newSeq = app.project.sequences;
Let me rephrase. I have 5 separate sequences that I want to combine into 1.
Is this possible?
There is no public API allowing for that. Perhaps you could export those sequences as FCP XML, and generate a new FCP XML combining/appending them?
