I’ve been using shotcut for like 4 years now, and i never had this problem.
I was trying to export a video but the program says “scaling of the preview is set to 720p” and i dont really understand how to solve that, since i need to export the video.
While i try to fix that, any kind of help are accepted.
Thank you.
That message does not block export and is completely unrelated:
It is a status message about the Settings > Preview Scaling menu.
What exactly happens when you click Export File or in the menu choose File > Export > Video?
Nothing. I click the export button at the top of the screen and does not export the video.
However when i click the export file button near reset and advanced* (like the button in your screenshot) it start the exporting process and does not export it, resulting in a failure.
I dont even know if i made myself clear, im trying my best to write this in english.
When i try to export it, this is what i get.
If you have an old GPU and upgraded Shotcut, it might no longer support hardware encoding on your old GPU. You can try turning that off. Otherwise, in order to fix export you need to right-click the job and view the log. See also Export failed - Find solutions
I’ve tried to see the log, but didn’t understand a lot about it. I noticed that i was working on an old version of shotcut, so i tried to update it but still the problem remains.
I honestly don’t know what to do anymore, i dont even know if it’s a GPU’s problem or a RAM’s problem or anything else.
The only thing i can relate to about the post you linked is the “failed with exit code” message.
We cannot see what is on your computer. Copy and paste!!!

That’s the log
Try to play back the exported file. It looks like this might be a false failure.
Ok, so: i tried it and shotcut still shows that there is a problem with the exported file, but it result succesfully exported somehow in the fileholder where i usually save my works, so it looks like the problem is solved even if i dont really understand how 
Anyway, now i’ll try to keep working on the video and if i see any other problems i will report them. Thank you for your time
