Can anyone tell me the requirements that videos that upload to the platform must have?

I tried to upload a video to the platform and they notified me of the following rejection message:

-Here is the comment from your Envato Quality team reviewer:

  1. Your submission appeared to contain too much visible noise, grain, compression artifacts, or gradient banding.

  2. When reviewing footage, we take into consideration a number of factors. A few of these factors is the composition of a shot, how it is framed, and how these factors effect the overall quality and usefulness of the clip. We feel as though the way this shot is composed that its usefulness is very limited.

Does anyone know something?
