Impress don't insert a video

Libreoffice Impress load the video but can not to reproduce it

I cannot reproduce your problem, with current LO 6.0.1 flatpak running on Fedora 27/GNOME. Downloaded http://downloads.xiph.org/video/A_Digital_Media_Primer_For_Geeks-360p.webm, then in LO Impress inserted it on a slide (via "Insert - Audio or Video..."). Playback works, and still works after saving and re-opening the .odp document (and also works in full-screen slide show mode).
Please be more precise what exactly does not work for you, in which environment.

Greetings, I'm in linuxmint 18.3, 64 bits, cinnamon. I tried to insert a video with mp4 extension on a slide. The fact is that it inserts it, but as an audio, you can not visualize the video, but the audio. I did the test with libreoffice appimage and it did not present any problem, the video is loaded and it plays well.

Indeed. Downloaded http://techslides.com/demos/sample-videos/small.mp4. After installing gstreamer1-libav-1.12.4-1.fc27.x86_64 from rpmfusion.org, the "repo-native" LO in Fedora 27 played the video. But the flatpak'ed LO shows just an audio icon.
I assume what is available on the host is irrelevant, and the flatpak just has available what is packaged in the underlying org.gnome.Platform runtime.

Right, if you want mp4 support, then it needs to be visible inside the sandbox. I know that there's talk of adding the newly 'freed' aac codec to the standard set and there may be some work on h.264. @ramcq is the best plugged in here.

Discussed on IRC - H.264 and AAC are present in the Platform.ffmpeg extension, but the platform doesn't ship gst-libav. Perhaps it should - ITMT, @stbergmann needs something like https://github.com/flathub/org.pitivi.Pitivi/blob/master/org.pitivi.Pitivi.json#L447-L459
