OJS 3.X - allowed files

Good morning everyone!

I have doubts so far and haven’t found the article or FAQ about my specific question.

I work in the area of Linguistics and Sign Language Literature, I have three more magazines that I related in the areas of sign language, sign language literature and sign language linguistics.

I wonder if OJS 3.x allowed that we put a PDF file for article + an MP4 file as a videos along PDF (button like PDF, HTML and Translation) has a possibility to include a button like video that we put an MP4 file inside the OJS?

Because the article / research has two text versions in Portuguese and another in sign language video

Because it is important for scientific research destinations that are related to Sign Language and also academic with a deaf community that is stronger in Brazil.

I hope I can with your help on my question.
