Thank you very much for your very fast reply.

I will try your suggestion on re-encoding the videos.

I know this should be another topic but I just would like to know how I can display the video title overlaying the thumbnail instead of what I did on this page: https://thinker.education/ with the 4 thumbnails videos. Right now, I just edited the thumbnail to include the title on them.

If you think this should be created in another discussion I will just create this new topic.

Thank you so much Eduard.
