Hello,
Seems like you mean Moto CMS HTML templates. Yes, there is no Video Player widget for mp4 files but one for YouTube and Vimeo videos.
Thank you very much for your idea! I have already added it to our Feature Requests List. Our developers will consider adding this feature in one of our future updates.
We really appreciate our customer's feedback. Please, contact us anytime!
Best regards,
Mathew Brown
