Hello and thanks for responding! I don't get an error message - I just get the broken link as shown in the photo. I'm not sure what this means though. After the video is done "uploading" there is no preview of the video, it just stays this way.

I don't see a broken link in the photo. Only a video being uploaded. Do this. Screen record the whole process. Upload it to YouTube and I can have a look.

Alrighty so I think I solved the issue. For some reason I am unable to preview the video when I upload the file - which left me with the impression that it wasn't uploading at all. I decided to submit the video once it was done loading - and the video uploaded just fine to Dtube, oddly enough. Still not sure why I can't preview the video though...

Anyways though, thanks a bunch for your help! :)

You can use Handbrake to pre-render the video. I always do it and it shows up in preview. You can try it!
