I’m probably missing something here - to be quite honest, I never really understood the initial post in this thread and changing file names. Whenever I want to embed something like a self-hosted video or a powerpoint/keynote Presentation, I use the standard video bric and select YouTube/Vimeo option. I then edit the source URL to point to the file on my server. This now becomes a reference link and doesn’t require embedding videos into the Blocs project.
The alternative is to simply add your remotely hosted videos to the asset manager like this:
You can then use the local/remote option in your video bric and select the remotely hosted video from the asset manager. Whichever way you do it, the video bric will simply display your content in a responsive iFrame - it won’t actually add the video to your project and will not, therefore, create a video directory in your site. Both of these options remove the issue of multiple video directories - a single video url can be shared between a number of sites.
Not sure why placing assets in different folders on your web server should cause security certificate issues. Most SSL certificates cover the entire domain including its sub folders. If you think about it, loading images from an images sub folder doesn’t create an SSL issue - neither should a video, whether it’s in an en subfolder or in the root of the main domain.
If you want to try it out to check what happens with your security certificate, add the following URL to your hosted assets and then add the asset to a video bric set to Local / Remote.
You should find that the video clip displays in your page, but when you export, there will not be a vid folder in the output.
