In and Out Trim of a copied playlist item is not overtaken

What is your operating system?

OS Name: Microsoft Windows 11 Pro
OS Version: 10.0.26200 N/A Build 26200

What is your Shotcut version (see Help > About Shotcut)?

Shotcut version 25.12.31

Can you repeat the problem? If so, what are the steps?

  • Playlist-only project

  • Open a file

  • Adjust in and out (let’s say in at 00:05 and out at 00:15)

  • Copy clip in playlist by pressing Shift+C and Shift+V

  • Clip is copied and opened automatically (the second of the the two identical files in the playlist)

  • Adjust in and out of now open second file to different positions (let’s say in at 00:25 and out at 00:35)

  • Go to first clip - in/out remains at 00:05 an 00:15 (as expected)

  • Go to second clip - in/out went back to 00:05 and 00:15 - Expected behaviour: in/out of second clip is at 00:25 and 00:35

Not a bug in my opinion.
Try this instead, which for me is the correct workflow.

  • Open a file
  • Add your first IN and OUT points
  • Instead of Shift+C and Shift+V, click the [+] button in the Playlist panel. This adds the content of the Source panel in the The Playlist.
  • In the Source panel, select different IN and OUT points and click the [+] button again to add the new IN/OUT portion in the Playlist.
  • Repeat

Additional information:
After you’ve added all your clips in the Playlist, if you need to edit the duration of any of them, simply double click on it (in the Playlist) to open it in the Source panel and change
the IN and/or OUT points.

That’s exactly the way I do it. However, if I need a second region out of the file, I have to duplicate the file and change In/Out accordingly.

Shift-A (or the plus-button) doesn’t work for me since the file is added always at the end of the playlist and I first have to sort again to see the overall result. Shift-C and Shift-V places them exactly underneath.

For me it is a bug, since the adjustment you set are lost, a user cannot expect that.

Edit: Shift-C and Shift-V is exactly what I need - just without the now necessary additional change of a playlist item to persist In/Out .

I still don’t see it as a bug. Just a behavior that doesn’t fit your workflow.
Just my opinion, but this thread should be a Suggestion, not a bug report.

But what’s the intention of letting the user adjust something, which then just vanishes? What’s the real purpose of the function, regardless of my workflow?I don’t get it.

This happens because Source acts as an internal clipboard viewer in Shotcut. So, when you Copy, the source player reflects a copy of that playlist item unlinked from Playlist. When you Insert, it does not change the clipboard and thus the contents of Source remain as-is. Then, after Insert, the content of Source is still its own clip–not belonging to any other container such as Playlist or Timeline, which is very often the case in Shotcut. Only the relationship between an Opened playlist item and Source is a special case. To do what you want you need to double-click the playlist item you pasted to Open it in Source to edit it. Changing Insert to also open might seem correct, but perhaps that is equally unexpected for another workflow (overwriting the clipboard/Source when it was not requested).

Another change you should probably make to your workflow is: Copy, trim, and then Paste. The trimming does not affect the playlist item you copied; it only affects what is in Source.

I am not planning to change anything here.

Your explanation helped me to understand, thank you very much.

This sequece could work for me, unfortunately by inserting it adds the source before the copied clip, which means the in/out 00:05/00:15 is after the in/out 00:25/00:35. They are not affected by sort by date.

Any possibility to change this and add the copy (with Shift-V/Insert) after the first playlist item?

When 2 is selected and you choose Insert the target is position 2. I am not going to change that.

There are Move Up and Move Down actions. Also, you can single click a playlist item and cursor up/down to change the target. These are such basic things you can learn to do. When you buy a new microwave oven, do you learn to use it or call the manufacturer and ask them to change it to the way you want it? Because we all know a microwave oven never works the way you want. :wink: Maybe some day there will be an Insert After or maybe not to prevent clutter.

Yes, I can learn that. It would be just more convenient and with less key presses. So at least I had to try.

I know it now, but will other users, especially new ones really understand that?

I wonder if there might be a possibility to copy playlist items without the clipboard just to ease the user experience - maybe with a new action “duplicate playlist item”.

In any case thank you for your quick responses.
