To add or update videos that display on the hero banner you'll need to move them onto the site server to:
$D9/sites/default/files/videos/iac_videos
If you want to remove the files we recommend moving them into:
$D9/sites/default/files/videos/old_videos
To get files down to a file size that's appropriate we use the following ffpmeg command
ffmpeg -i "inputvideo" -filter:v scale=1024:-1 -c:a copy "outputfile".mp4
The above command is encapsulated in the scripts/ directory of github.
