SetInPoint() For ProjectItem and TrackItem objects?? + How to edit Items in the tracks/ timeline?

>>AS for final solution related to QE...it has been PURE PAIN, trying to understand any of it

>Precisely why QE DOM is 100% unsupported, and not-at-all recommended.

What was very difficult to grasp, was to see so many posts throughest the years doing the same thing we want to do, things not always available in the accepted docs, only to get denied with the imposisbility of getting more info (at least not here),

Thanks a lot for the answer.

>trackItem.inPoint (and .outPoint) are read/write parameters; no setters necessary. 

Interesting, thanks for pointing that out for me.

I actually went experimenting to see:

Here is my TrackItem:

Initial Values:

clipsInTrack0.outPoint.seconds=>2.76

clipsInTrack0.end.seconds =>10

Testing the writing functions on .outPoint or and .end, for track items:

var time2 = new Time();
time2.seconds = parseFloat(300);
clipsInTrack0.end.seconds=time2.seconds; //does nothing it seems

=> result:

Nothing.

Maybe the "item" cannot get to higher "values" than its max? Ok then lets try a lower value:

var time4 = new Time();
time4.seconds = parseFloat(2);
clipsInTrack0.end.seconds=time4.seconds; //does nothing it seems

REsult:

Unphased!

Let's try again( hours are passing since first day I wanted to automate this)

var time2 = new Time();
time2.seconds = parseFloat(300);
clipsInTrack0.end=time2; //It finally worked!

OK that's for Start and End.

But what is this "inPoint" and "outPoint" concept again?

I tried modified its value with:

clipsInTrack0.outPoint=time2;

But NOTHING happened on the tracks/timelines. The trackItem remained as is!

Now I tried to experiment a bit on ProjectItems:

I tried to modify the inPoint and OuPoint

Not sure what happened.

Since I still don't know what are these "attributes" whatsoever.

While I am waiting to learn more from the classical accepted API (on this post), I will go explore (the other "side" option) in the meantime, to see what I can do aswell. It would be good to know every option of course (the options mentioned here and the options I mentioned on those pictures, the .. barrier)

>I am unfamiliar with that extension. We're not gate-keeping anything. While QE DOM does exist, it is neither recommended or supported.

I know but it remains a fact, that as for today, that "paid option" is the only way there is "it seems" to get consistant constant numerous info about QE. (It seems). Which "seems" like a "gate", the rest of the websites related to this type of info do not exist anymore (many of them) it seems.

Of course, this is just a feedback, which could be helpful for the future ("Cliens feelings lol").

>There is no such thing as a "cut", in the API. To accomplish that, you would adjust the start/end of the existing trackItem, then insert a new trackItem, referencing the appropriate time range from the source projectItem, and (presumably) occurring immediately (i.e., having start/end values that place it) before or after the previously existing trackItem.

This is very interesting, this is indeed what I am trying to lean into, however my plan as I was imaging it was:

- Insert clip, modify start and end

- re insert same clip (stil using the same projectitem variable)

-> modify its start and end

Provided I HAVE A WAY TO KNOW where it is located when getting the track items.

The problem is they would have the same names and attributes, it could be tricky to know which one I want to modify?

I suppose I can compare their "start" time, since I can decide where it shall start with the insert function. (If I am wrong  somewhere You can correct me).

Final thing:

I saw on the other thread someone using FPS and "

var fps = clip.getFootageInterpretation().frameRate;

"

Do I have to get to THAT LEVEL to be able to insert and "move" things with precision or I can do without it?

I never paid attention MUCh to fps or anything, I have always  relied on Premiere pro to "deal with it", although I had various questions about its precision once https://community.adobe.com/t5/premiere-pro-discussions/inconsistency-in-audio-durations-frames-clip-posistioning-relative-to-the-30-frames/m-p/14304491, I maybe should start paying attention to that. If you have guys any extra info about what is the best way to do this, please go ahead.

Edit:

>For clarity's sake: There is no such thing as a 'clip', anywhere in PPro; there are only projectItems, and trackItems. So, to restate your request...It seems like you'd like to put the same projectItem into tracks as two different trackItems, with different start and end values (relative to their position within the sequence), and different in and out points (relative to the time span in the originating projectItem). Do I have that right? 

Yes!

By re reading this I am starting to understand the in and out point (its the way we "cut" within the same clip in some sort), but it did not work when my track item was on the track it seems? Have little faith on it working on projectitems.
