Reinventing the animation timeline: balancing simplicity and precision
In 2021 I worked on a legacy ad-creation tool that was being used by large advertising customers to build rich, interactive display ads. The tool supported advanced capabilities such as animation timelines and bespoke code, allowing users to create highly customised creatives.
In practice, however, the experience had fallen behind modern standards. The interface was dated, difficult to use, and did not match established patterns seen in other professional tools. As a result, the product struggled to attract new customers outside its existing ecosystem and was at risk of becoming irrelevant for experienced designers.
The goal of this project was to re-invent the ad-creation experience from the ground up, making it appealing to a broader audience while retaining the depth required by expert users. This case study focuses specifically on redesigning the animation timeline, one of the most powerful but least usable parts of the tool.
We needed to design for three distinct customer groups with very different needs and expectations:
I conducted user interviews with existing customers which helped to highlight consistent issues with the current animation timeline. Many users struggled to even find the timeline within the interface, and once discovered, it offered limited flexibility and control. The timeline did not resemble industry-standard animation tools, making it difficult to understand what was happening over time or how animations were constructed.
From this research, I defined several guiding principles for the redesign.
The core challenge was designing a system that felt approachable to new users while still offering the depth and precision expected by professionals. To achieve this, I came up with a concept that allowed users to design at different levels of complexity depending on their needs.
Animations were built using three interconnected concepts: effects, keyframes, and code.
Effects acted as reusable bundles of keyframes that covered common animation patterns. They could be dragged onto the timeline, resized to adjust duration, and repositioned to control start and end times. This made simple animations quick to create and easy to iterate on.
For users who needed more control, effects could be expanded to reveal the underlying keyframes. Keyframes provided precise control over individual properties and behaved in a way that was familiar to users of professional animation tools.
At the deepest level, all animations mapped directly to web-friendly code, ensuring transparency and accuracy. This one-to-one relationship reduced errors ensuring it would render correctly across all browsers.

The above solution was truly unique, in that competitor tools had both effects and keyframes but they did not have a relationship to one another.
I conducted usability testing with five existing users of the tool to validate the concept and interaction patterns. From these sessions I learned that:
Early testing did reveal friction around discoverability. Several users struggled to understand how to add effects or reveal keyframes, this led to iterations with the iconography used, and when testing future iterations this was no longer an issue. Feedback also highlighted a desire for more control over effects without needing to edit individual keyframes, which resulted in the introduction of an effect editor that gave users control over properties like direction, easing, and distance.
Later in the project, I was able to test the design in production using an early alpha build.
Ultimately we learned that there was a strong appetite for the underlying concept of building animations in this way. Whilst alpha testing raised a lot of limitations with the tool, Beta testing showed slight improvements and showed that as we fixed the technical issues the tool became a lot friendlier to use.
Future plans included improving quality-of-life features such as snapping, keyboard shortcuts, and other expected features which designers were struggling to use the tool without. We planned to introduce templates and component libraries to reduce repetitive work. Broader integrations with adjacent advertising tools were also planned to strengthen the overall ecosystem.
Ultimately, due to shifts in the wider advertising landscape, the project pivoted before it could be fully launched in its intended form. Despite this, the work provided valuable insights into designing complex creative tools, balancing approachability with professional depth, and setting realistic expectations when building products for expert users.
