@external gamer,
are you seeing poor quality before you re-encode, when you re-encode, or only when it's uploaded to youtube?
I suspect it's YouTube, and there's not a lot you can do about that.
If it's appearing before you even re-encode then use a better codec for capturing your content in Bandicam. Again, I use MPG1 VBR @ 100% quality, and find it's a fine compromise between image quality / file size / and speed for editing.
