Granted, all hell breaks loose in this video so I understand why Youtube would have trouble with it. Quality loss truly begins to get frightening during the explosion below. I tried lowering saturation and it worked for certain areas. Perhaps I should just remove Trapcode Shine from the second screenshot? Youtube absolutely hates quality, I'm even using the correct presets. (media encoder and premiere both give good renders, but youtube kills it)
To clarify; My render looks fine (using the Youtube 720p 30fps preset in Premiere), the problem arises when youtube converts it. I've tried using Media Encoder with the same result, the render is fine but youtube simply can't handle it.
Advice/criticism would be more than appreciated.
