Crash changing Properties > Audio > Track with proxy

Bug

What is your operating system?
(If you are using Linux, you must state how you installed Shotcut as there are too many builds and packages. In general, we do not make the build installed by your distribution package manager unless it installs the Snap. The developers only build, test, run, and support the builds shown on our download page.)

Windows 10

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

25.3.29

Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)

  1. Create and save a new Project
  2. Enable Proxy Creation
  3. Restart
  4. Open Project
  5. Pull in a Video File (mine is ~1 GB)
  6. Wait for the Proxy being done
  7. Restart and open Project
  8. Create two Audio Tracks
  9. Pull in the Video File on each of the two created Audio Tracks
  10. Select one of the Audio Clips and switch the Audio Channel to another Audio Channel
  11. Shotcut seems to do some work but then crashes

It doesn’t seem to make a difference which of the Audio Tracks is changed like this.

And also if I only pull the File in into just one Audio Track this still happens.

What seem to help as a workaround is to Copy-Paste the Video-Track to the Audio-Tracks and change the Channels then.

I think Shotcut can’t correctly handle Video Files if there is already a proxy existing for this File. My thought was that Shotcut knows the File already and internally already links it to the proxy and dont use the real file.

No other Logging. No real Logging in Windows either.

Your report is difficult to follow because you mix up the English words for things:

  • Channels → Tracks?
  • Tracks → Clips?

I am not sure what step 10 is. Are you referring to Properties > Audio > Track or re-ordering tracks (Move Track Up or Down)?

You are right. I have edited the post accordingly.

This does not mean anything in the English version of Shotcut. And neither can I guess what you are describing. There is no “Switch…” function in Shotcut.

I quickly recorded it:

OK, that is in Properties > Audio, which was never mentioned even after asking. Maybe as as workaround, drag the file to the player first instead of directly to the timeline. Change properties before adding the file to the timeline.

Yeah sorry.

I will set language in Shotcut to Ebglish for now. Then it is easier for me to explain. I am not that used to the Wording in Shotcut or Editing Software in General.
