I'm having an issue with clips suddenly not working

Help/How To

Hello!
I hope you’re all doing well! :slight_smile:
First and foremost, I’m new to shotcut. In fact, I’m new to editing in general (aside from the basic cropping of videos and what not), so I hope you could be patient with me…

I’m having an issue that I’d love if you could help me with cuz it could potentially be devastating for work progression.

Here’s the scenario:
I’m working on a clip for a compilation video of many gameplay clips edited and merged together. I add a new clip, edit it however, I’m done with it, I add a new clip, do the same rinse and repeat 2 or 3 times, and then when I playback the whole thing again, suddenly for no apparent reason, some of the previous clips that worked perfectly before, are now frozen! (The 1st time it happened the video froze, the 2nd time it happened the whole clip, video and audio froze.)
I’m not sure what’s causing it as I’m not meddling further in already completed clips, I just move on to the new clip and start editing those exclusively making sure I don’t touch the older clips.

This could be really bad because I could work on a clip very hard only to repeat it all once again…

Currently I’m somehow working it out by:

  1. Opening a new instance of shotcut of a previous version of the same project where the clip in question is working fine. So now there are 2 instances. We’ll call those 2 instances “Faulty instance” and “Working instance”.
  2. In working instance I delete EVERYTHING on all timelines AFTER the working clip marker, and keep everything behind it.
  3. In faulty instance I select EVERYTHING on all timelines after the working clip marker, and paste it right after the working clip in working instance.
  4. Now the clip that used to work right is behind the new edits.

Issues with this method:
1- It’s scary cuz who knows what I might or might not be able to copy for whatever reason.
2- I can’t copy markers that I had in the faulty instance to the older, working instance.
3- It’s slow especially if you’re copying/deleting a lot of clips.
4- It’s tedious as you might have many small segmented clips on the different timelines that you have to zoom in and out and click on each of them.

So yeah I’d highly appreciate if someone could help me understand the root of this problem to begin with, so that I can stop it from happening or at least quickly fix it in case it happened.

I’ve attached to this post the 2 instances “Faulty/correct instances”. The only differences are that the clip at time “00:01:07:07” is working in the correct instance, and not working in faulty instance, and that the faulty instance has more markers on it.

UPDATE!
I just found out, it’s only happening to clips that I have used the filter time: Remap on.
I do it to keep the clip frozen on a specific frame for some time, as per this guide: Continue last frame of clip until next clip - #5 by MusicalBox

I’m not sure if I’m doing something wrong or what…
Here’s what I’m doing when time remapping.
I split the clip and delete the part I don’t need.
I place the playhead on the last frame in the clip (The one right before black screen), and I add filter time:Remap.
I press the [ > ] of the time:remap filter UI, and I set speed to x0.00000.
press OK.
Drag clip further to the right on timeline to give it the amount of frozen frame time I desire. Move on with my life.

Is there anything wrong I’m doing that might be causing this issue? It keeps happening.

I followed your instructions to use the Time Remap filter to freeze the last frame of a clip. I tested in both 24.08.29 (latest version) and 24.06.26 on Windows 11. The instructions worked perfectly for me in both versions.

Your problem sounds similar to this problem reported previously by another user.

Unfortunately, I have not been able to reproduce that problem. And if I can not reproduce it, I can’t fix it. I wonder if it is related to some difference in system configuration like language or locale.

As a workaround, you could make your time remapping edits in another instance of Shotcut and then export an intermediate file to import into your main project. Similar to the work-around you are doing today.

Thank you for the reply.
No worries, I decided to just export last frame then re-use as image.
That will make things much more organized and less wonky.

Thank you nevertheless :smiley:
