First, I must apologize for the blurriness of my DS :(.
Secondly, the site that I am using is: http://www.pokecheck.org/
To explain what I mean about ID/SID for RNGing:
Basically, you will have to upload a Pokemon that you have caught or hatched yourself to find out your SID. But when you RNG your Pokemon, you don't have to use a Pokemon you caught or hatched yourself.
Tip: Do not make the video full screen, as this will make it blurry. If you have trouble seeing anything, just make it the next size before full screen :).
