Can someone the actual meaning of 780p vs 1080p and how frame rates play into all of this? Are there other factors that play into quality as well?

1080p and 720p are resolutions. Basically with 1080p there’s 1920×1080 pixels and 720p is 1280×720 pixels. The quality comes from the fact that the camera is able to capture more data. This is why 2K, 4K and 8K look more realistic as you go up. They’re better able to capture more data.
A good way to think of resolution is the evolution of gaming. When you look at old 8bit games the characters don’t have too much data. As time went on 2D characters were able to hold more data and have more details.
Frame rate is how many times the camera refreshes or takes a picture (frames) in a second. The more FPS, typically less choppy. If you had 1FPS the screen would display each frame 1 second apart, which is pretty noticeable. When you record at a higher FPS the time in-between frames is less and you notice each specific frame less. Technically there is a point where FPS doesn’t matter, you won’t notice any more smoothness.
Another thing that affects quality is bitrate. When streaming you want to have a higher bit rate, especially at higher resolutions. Bit rate is the amount of data processed from the video. If you choose to low bitrate the video appears grainy. There is a flipside too, if you choose too high bitrate, the video will buffer. This is also why sometimes streaming 1080p might look similar or worse than 720p.
On last thing that affects video quality is encoding/decoding or codec. Basically the idea is that you convert and compress from one format to another. Compression is used to make the file size smaller. Some formats lose more data than others, which affects the quality.
