Hi @Sean-McG,  
That is indeed a very nice set of nodes!  
But I have already a few different brands of camera's now, and as you can see above there are already some good experiences for Amcrest cams. So I will need to expand my **Onvif** node set a bit more in the near future to make them a bit more user friendly. By using Onvif, my PTZ and event streams and ... should work on all camera's using identical Node-RED flows.

But this discussion is more focussed on using the mp4 related nodes from @kevinGodell. I have (e-read last week the [storing-video-as-mp4](https://discourse.nodered.org/t/storing-video-as-mp4/41911) discussion again, but need to let it digest slowly. Seems there are different ways to store video, but need to have a fresh brain to get the entire 'picture'. Would like to create an overview, with pros and cons of each way of working...
