You did not include the encoding portion of the log, which will show us the settings used to generate the output file.

Also, what are you trying to play it back on?

I have yet to encode it. My video file is already in that state of black screen without audio. I am trying to use VLC to play it.

Then we really can't help you yet... If the source isn't usable, the circumstances where handbrake would be able to help that situation are few. But there still are some; why not give it a try? It would give us more information to work with, at the very least.

Handbrake uses the same libraries as VLC, so if VLC can't open it, ...
Use MediaInfo to post your source file properties; someone "may" be able to help you.
