Mix Clips Suddenly Not Working

Hello. Newbie here.

I am having an issue where Mix Clips quite suddenly stopped working for me.

I select mix clips, and get 2 errors: ‘2 items selected’ and ‘no active track’.

I ungroup the video and audio and it stops the 2 items selected error. I’ve never had this issue before though. I’ve been able to mix V1 and A1 at the same time just fine before.

It still doesn’t fix the ‘no active track’ issue. I definitely have a lot of frames for the mix clip. I trimmed off around the raw video and it still doesn’t work.

In fact, I deleted mix clips from an earlier part of the video and tried mixing clips again, and it gave the same error.

The differences in this editing session is I found the U key is a shortcut for mixing clips, but it does not work whether I press U or the button above the timeline. I also added a new folder of videos to the Project Bin. It appears to have started right after I added that folder, but removing that folder and videos makes no difference.

I tried updating KdenLive, uninstalling and reinstalling, did not fix it at all.

I made a new project and found mixing clips worked normally again. So something is up with that specific project I have. Any ideas on what’s going on and how to fix it? I don’t know if I accidentally activated a setting or what.

Hello and welcome to the forum.

On which OS are you (Windows, Linux, Mac)?
Please upload here the project file which have these issues.

Hi. Thankyou for replying! I am on Windows 11.

I tried uploading the file to here but it wouldn’t allow it. Says the file type is not authorised? Is there somewhere else I can upload? I can also record a video of the issue.

Try with a zip file containing the project file.

Hi Eugen.

That did not work either. It appears I can only upload image files. Says I’m only limited to jpg, jpeg, png, gif, heic, heif, webp, avif, svg.

I tried uploading to google drive. It downloads and works fine for me, even when logged out. But the forum won’t allow me to post links. It says I can’t include links in my post? I tried both posting a raw link and inserting a link option.

So I’ve screenshot the link and uploaded it as a png file. Though it would be a pain to type out.

Sorry for being such a bother.

Thank you for the project file. I see the “error”. You have accidently made the track inactive by clicking on it.

Click on V1 and A1 respectively that it gets green again, then the mix will work again.

Thankyou so much! I have no idea how I did that. But thankyou!
