Fedora-based templates out of the box cannot play some common video formats such as mp4. This tutorial installs the VLC Media Player in Fedora. Installing VLC in debian-based qubes is also an alternative (and may be easier).

To install VLC in QubesOS v4.0.3

Let's add extra software repositories (RPM Fusion) to your fedora. On a Fedora-based TemplateVM such as fedora-30 open the terminal and type:
sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E%fedora).noarch.rpm
sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
dnf -y update
dnf install vlc
If you get the error No package vlc available. Error: Unable to find a match. while running dnf install vlc, then you should do:
sudo gedit /etc/yum.repos.d/rpmfusion-free.repo # or any other text editor
The line which will need editing will be near the beginning probably 7 lines down:
enabled=0
Change the 0 to a 1 and then save and exit.
Now re-enter the following lines in the terminal.
sudo dnf -y update
sudo dnf install vlc
VLC should now be installed successfully in the TemplateVM. Then shut down the TemplateVM and any AppVMs based on that TemplateVM for changes to take effect.
The you start the Fedora AppVM and you should be able to play video files (they'll open in VLC). If it didn't work, comment down bellow.
Optionally you can also add VLC Media Player to your list of applications.
