no video with supported format and MIME type found

These videos are being loaded into in a web object in Storyline.
I'm getting this error when publishing to Review 360. The videos files are MP4 published with Camtasia. Everything works fine playing from my local drive. The video files are about 5 MB or less in size each.

I addition to Review 360, I tried uploading to a testing server.
The Firefox web console showing failure to load the video file... but there is nothing wrong with the path or file name in the Story and index.html. It works fine on local drive.
HTTP load failed with status 404. Load of media resource https://seismic.aerobaticapp.com/story_content/WebObjects/61akx79kEC0/Accessing-the-Content.MP4 failed.
I tried it in Firefox, Chrome, and Edge.

It seems the problem has to do with Storyline's implementation of web objects. When I embed the video in the slide the problem goes away. The downside is the lack of good video controls with embedded video. For one, I want to be able to go full screen with the videos which you can get with HTML5 but not with Storyline's version.
There might be a problem with the encoding of your video. What version of Camtastia are you using and what settings? I've had good success using Camtasia 2018 with standard export settings. This should be an easy fix by re-encoding the video with either Camastia or another tool.
You could even use Storyline to encode your video file. Create a new blank project, insert your video, publish with the video quality settings you want, and then copy the mp4 file out of the published folder and into your web object folder of your original project.
I did use Camtasia 2019 to encode the videos. I believe the problem has to be Storyline's web object. When I embedded the videos in the slide they worked fine. Unfortunately the video control options are sorely lacking but it is what it is.
When you embedded the video into Storyline, it is likely that Storyline re-encoded the video for you and that's why it worked.
Go to the published output of the project that worked, grab the video out of there (search for mp4 files) and then insert that video file into your original project with the web object. Many others are using videos in web objects this way, so I'm leaning towards it being an encoding problem with the original file.
