How can you create motion design that works across multiple platforms?

Always ask the client or the marketer first, which platform it is going for. As example, if its going for ads you will need three ratios and most viable is to start with a 1:1 ratio cause you will always be able to expand and make it better. If its for social media posting you can just go for the exact ratio and tone they want and you're less likely to be on a unsafe space.

from my experience with different clients espically those whom at first ask you for just a may be 9:16 video then suddenly when they are so happy with the end results they reasked you to provide another 2 dimentions version like 1:1 , 16:9 for example. Before starting any motion design project, outline your target platforms and their specific requirements. This will help you create a roadmap and ensure that you address each platform's specifications during the design and production process.

From my experience working in web design, I found it very helpful to not design animations that will fit a certain screen. We should be designing animation that will work on any screen size without adjusting it too much. We can do that by paying attention to the size of the animation itself and having it work by itself. On the other hand, if we talk about scrolling animation and interaction, that might need to be designed separately at least for laptops, mobile, and large screens in order to make sense.

I found that some motion works better on different devices. Sure re-using the same motion for mobile purposes and a TV ad sounds like a time-saver and a consistency to your work. But often I find that once you know it will be played on extremely different sizes, the motion doesn't scale quite right. Every motion uses a weight, velocity and intent. Sometimes it just 'feels' different when used on a different screen. A swift motion might seem too bulky on a bigger screen. And a smooth easy-out animation might feel to slow when translated to a smaller screen. Don't be afraid to keep tweaking and stray a little bit from the average that works on all your screens and devices.

In a prior client collaboration, adaptable motion design was pivotal. Picture this: tasked with a compelling animation for a product launch, it had to shine on their website, mobile app, and social media. Incorporating adaptability, we ensured legible fonts, strong color contrasts, and scalable layouts for universal readability. Implementing keyboard-accessible navigation ensured effortless interaction across devices. I enjoyed the project and it was a learning curve. This approach met diverse platform requirements and accessibility standards, showcasing our dedication to inclusivity. The animation dazzled on every platform, emphasizing adaptability's essential role in motion design, amplifying the product launch's success.
