What's the video file format that you are using. LibreOffice Impress used to be particular about which could be used.

[haitem-belgacem]

i tried some format.
H264, H265, MPEG
with some containers, .MP4, .AVI, .MPG

the documentations say , libreoffice read all format via gstreamer, if a video is normaly readable on ubuntu, the video will work in libreoffice.
the package "libreoffice-avmedia-backend-gstreamer" is here to make the relation between libreoffice and installed codecs
