One of our top products in my company, RanDom Studio, were these GIFs. These brief animations let small businesses to have a promotional animation without spending too much. Furthtermore, the GIF format allowed our clients to easily add them to their websites, emails, presentations and even send them by whatsapp. This is a colection of our favorite ones.
To create them we bought vectorial designs online which we animated in After Effects and sometimes personalized with Illustrator. This strategy let us minimize expenses in order to offer lower prices to our clients, saving us productions time as well.
