Dear Jack Robinson,
If you create a BIMx Publisher set, and add a view you saved of a camera path to it (so not the individual cameras but the whole path), it should be saved out into the BIMx file as a video by default.
This video will be playable from the favorites in the mobile app. Here's an article explaining this.
On the desktop app you will be able to play the movie as well, you just have to click on the preview picture of the item in the gallery (see the attached picture).
Regarding your error, I am not sure what might be causing it based on this, I would need to see the file to be sure. I can try to take a look if you send it over to me, but you might be better off contacting your local support team about this, they should assist you much faster.
