I checked with CharGPT and got the following:

The hybrid_fragmented flag was added to FFmpeg in version 6.0, released on June
5, 2024. This feature allows for the creation of hybrid
fragmented/non-fragmented MP4 files, which can be useful for ensuring file
readability even if writing is interrupted

For installing a newer version than with the distribution:

You can install the latest version of FFmpeg from a PPA that maintains
up-to-date builds.

Warning:

if you encounter issues after upgrading, you can revert back to the version
provided by the official Ubuntu repositories. This can be done using a tool
called ppa-purge, which not only disables the PPA but also downgrades any
packages that were upgraded via that PPA back to the versions available from
Ubuntu's official sources.

Procedure:

1) Install ppa-purge:
sudo apt install ppa-purge

2) Add the PPA:
sudo add-apt-repository ppa:jonathonf/ffmpeg-4
sudo apt update

3) Install or Upgrade ffmpeg:
sudo apt install ffmpeg

4) If something goes haywire:
sudo ppa-purge ppa:jonathonf/ffmpeg-4

Using ppa-purge will revert FFmpeg and any other packages affected back to their
versions in the official repositories, ensuring system stability.

I will test this on one of the backup systems first....
