Impress and video

Can someone please help this senior who have to give a presentation shortly and I am trying to use Impress on LO Version: 6.1.4.2 (x64), on windows 10. I do not have access to PowerPoint.

  • I am testing integrating video into my presentation and I am testing this with a video in .AVI.

  • Do I have any control over my video when presenting?

    • Can I pause the video ?
    • Can I adjust the volume if the audio ?
    • Can I even smoothly advance to the next slide before the video finishes.
  • I do not see any type of toolbar to control the playing of my video inside of a Impress slide.

  • What file formats are supported? I would use .MP4 if I could.

Any advice you might have about using video in Impress would be greatly appreciated.
Thank you for your time and expertise.
