2.1.4 is crashing when I try and select an export location, with the Error "Error: java.lang.NullPointerException: Rendering Gui" (full logs below). Apart from that, it works perfectly and can render things just fine with no crashing. On another thread, you told the person to try with 2.1.3 as you changed a lot of the code for 2.1.4. This worked for me, but when rendering a replay with shaders enabled (using the latest version of optifine for 1.12.2, tried with different FFmpeg version and different shaders), the resulting file is unusable as it is flashing different colours with only the entities rendered mostly correctly on some occasions. See these videos (warning: flashing images):

I presume that it is something I am doing wrong. The Ideal solution is to get 2.1.4 working so that I can select the output location and name of the file without it crashing, but fixing the shader issue on 2.1.3 is just as useful for me.
If you would prefer to fix 2.1.4, here is a video showcasing the issue:
