*FIXED - Overlaying multiple videos is producing black flicker.

This video explains what I think is happening as the rest of the render seems to be fine,

This video shows my settings.

And here is some info on the source files,

I just want to be able to render this video without having to deal with a black flicker. I've tried many ideas, turning GPU off, updating codex... Any help would be greatly appreciated.

*FIXED - I went into my graphics card settings, and I enabled a setting on it called "OpenGL Triple Buffering" and for some reason that worked paired with some OpenGL settings in Options>Preference Shift Click> internal turned to FALSE.

Your video source has a very variable bitrate of 15-60 fps. Vegas software does not like such files. Those files you have to convert first to Constant Bitrate.

Not sure if this applies here but I used to see a snowy effect in black areas in blue rays I authored whenever I used gpu-assisted fx. Turning off the gpu alone helped but did not make it totally go away. Going back in and replacing each fx, selecting only from the 32-bit floating point section, did the trick.

I had a fade-to-black flickering issue recently on parts of the project after rendering an AVC. After tearing my hair out (what little I have left), I discovered it was the media players on the particular PC I was using. MPC and the Win Media player exhibited the behavior, VLC and another did not. It was ok on other computers as well. All was fine after YT's re-encode too
