Hello Marcel,
If I go with your host I would like to be sure about several things:
1. If I upload video files that require subtitles, ads will interfere in any way with the viewer experience?
Meaning to cover, at any time, the subtitles of the video.
2. Does the video required the viewer to do a certain action?
Like installing a specific software or to use a specific browser, or both, in order to view the file.
3. Is the viewer safe from malware, adware, etc?
4. Is the user compensate for each download of video files or only for view?
5. Are the video files safe from beeing downloaded whitout contorization?
Meaning whitout using the standard download option.
Cordially regards
Cristian
