This is in no way a real ad but just an animated gif that looks like an ad.
The reason I have made this is because it's for a film project in my animation class. Our group wanted an emulator ad for our film so I volunteered myself to make it.
Sorry if it's very cheap looking.
Step 1: Finding An Ad
It's easy enough to find an ad by searching up Youtube ads through Google images. Once there, search through the different ads and find whatever one you think is good. Click on it so the image is larger then press the "Print Screen" button. Go to a simple program, like Ms Paint and paste the screen there.
I'm not using a complex program like Photoshop because not everyone has Photoshop since it's an expensive program. Not only that but it's a good program when dealing with small pixelated things which is what this ad is.
