Download 12 Hour Video Timeline

I need to give my county road commission an overnight video of the traffic on our road. I don’t see a way to download the complete timeline from 5pm to the following 4am. Downloading one hour chunks of time is ridiculously inconvenient on my phone and there are only four ‘movement’ videos online which surprises me since I thought I’d see the same thing on my online dashboard as I do on the app. Silly me! How do I download a complete chunk or earmark that part of the timeline with a link so the road commission can view it? (Android/Galaxy S22Ultra)
