Modification of the Unity plugin (C#-script)

Programmer services are required. You need to mob the Unity plugin. Idea: Make it possible to render the synematics of a board game based on time parameters (start time, duration) in the game itself by pressing a button.

Task: You need to refine the C# script of the AVFX movie recorder plugin / or Video capture (but then you need additional revision of the output to the build-a folder). You can take a similar functionality to the AV Pro Movie Capture plugins (but it works only on PC) as a basis.

The required scheme of work (briefly) on the part of the user:
- Launch the game.
Press the render button once at any time (and it is possible to run the synomatics first)
One synematic with a given duration is counted into the folder with the game

Requirements
1. It should not be dependent on the time of the game (when you click on the button render the specified frames of the synematic in the video)
2. Video renders in folder with build-om
2. For PC and Mac, at least after compilation.
3. Adding the configuration interface to the unity itself will not hurt (but it is enough to show the change in the time parameters in the code)
