I am looking for animated graphics (such as an envelope/package opening and the page comes out to read), but I’m not sure where to look to purchase or obtain for free. Any suggestions? Maybe there is a simple way to create it on my own, but I’m not sure how. I know you guru’s out there have some ideas!
Stock animations are somewhat harder to find. If you find it, mostly it will be stock video. ( http://www.motionelements.com/animation/3d-animated-elements-stock-footage-1 ) Or animations purposed for video-use in some postprocessing tool like AfterEffects ( eg. https://www.videocopilot.net/products/ )
