You can also upload your videos to github and embed them into your infinityfree website
I just made this page on my site to test it
https://zoltar.eu.org/code/video-github/video-github.html
<video width="640" height="480" controls><source src="https://github.com/LoveBug2084/test/raw/refs/heads/main/arnold.mp4" type="video/mp4"></video>
I uploaded the video to my github repository here
https://github.com/LoveBug2084/test/
And then clicked on it to get a page with a link that says view raw
Then copy that view raw link and use it as the hotlink in your website video player
