Since there is no documentation, I decided to write up a simple one, because it's not all entirely intuitive.
Honey Select Studio Neo Movie Maker Unoffical Guide
Assuming the correct version of the 0.5 dll is installed in plugins...
Press the left Alt key to bring up the moviemaker slider.
Select Add action and add "Static Camera Position" at 0.00 - this must *always* be done for every movie.
The Camera Continuous selection is an end point. So if you have your static position at 0.00 and set camera continious at 2.50, when the animation plays the camera will swing from the static position to the continuous position in 2.5 seconds.
The camera does not easily offer panoramic movement. It basically only works at 180 degrees of movement at a time or less. The continuous movement is based on the last static camera position. So if you swing around 170 degrees to the right, the camera will move right 170 degrees, but if you then set another "continuous" point without resetting static, and move 40 more degrees right(total of 210 now), the camera won't move 40 degrees further in the same direction. It will instead swing around in the opposite direction to reach that point.
A tip for making video recordings:
Set the initial static camera position at 0.00 and then set the exact same static position at 3.00(or more) and then make your movie from this point. That way after you start the movie, you have time to hide your menus so they don't appear in your video.
Light weight video recorder:
I suggest using oCam(not Bandicam or OBS). It is less resource demanding, and allows you to capture only a selectable portion of the screen, so you can avoid recording the greyed out GUI elements in the top right.
Troubleshooting:
If when you press the Left Alt key a tiny little dot appears above and to the left of the Add button, then you're using the wrong dll version for your studio version(some versionds of studio don't work with any moviemaker version)
