Files silently missing on export (proxied videos?)

What is your operating system?
macOS 10.14 Mojave

What is your Shotcut version (see Help > About Shotcut)?
Shotcut version 22.12.21

Can you repeat the problem? If so, what are the steps?
It seems like some Shotcut is fine to generate previews with all the clips I’ve included, but when I export, some of the videos (and images) are missing. I don’t get any warning, I just notice missing content in the exported MP4. This has happened to me on multiple projects. I wonder if it has something to do with proxy generation. I can save the project and reopen it, the preview will still include everything, but the export will again not include the files.

Your version is too old, you did not provide steps, and I don’t know how to reproduce it. You can workaround this by turning off proxy and loading the project; Shotcut will tell you if something is missing.

Hm I hadn’t realized how old my version was. Not sure if the fix was temporary, but disabling proxies and updating to the latest shotcut solved my issue.
