Why medical Explainer videos are so important
Project Spotlight: Cerebrolysin
About the project
In 2020, together with Creative Director Josef Schinwald, we created full CG 3D animations for EVER Pharma. Spread over five Explainer videos with a total running time of 15 minutes, the way cerebrolysin works in the brain is illustrated in detail.
Cerebrolysin: effects and benefits
Cerebrolysin is a drug from EVER Pharma that protects and repairs nerve cells in the brain. It is mainly used to treat Alzheimer's disease, strokes and brain injuries. Some people also use it outside of the official approval, for example to support mental performance, although we naturally advise against this.
Why are 3D animations so valuable?
Processes in the human body and their medical implications are often difficult to understand. 3D animations clearly show how active substances - in this case cerebrolysin - work in the brain. They help doctors and patients to better understand the treatment and facilitate their training. Here are the most important advantages of 3D visualizations in the medical field:
More effective medical training
Medical students and specialists learn anatomy, disease processes and interventions more clearly.
Precise surgical planning
Surgeons use 3D models to prepare operations more precisely.
Better patient education
Complex medical information can be communicated in an understandable way across language barriers.
Support for research & development
Pharmaceutical and medical technology companies use 3D animations to illustrate mechanisms of action and new technologies.
How much effort is a 3D animation?
3D animations are the most elaborate form of Explainer. However, the production process itself is more or less the same as with conventional Explainer videos. Here is a timeline that roughly outlines the production process:
Behind the Scenes
The creation of 3D animations
The animations and 3D models were created using Blender. The project was then shaded and rendered by an external supplier. The next step was compositing/grading in Nuke and finally sound and image were combined in After Effects.
The 3D models
For the animation, all elements had to be modeled first. Here are a few excerpts.
Turntables of all elements found in the human bloodstream: Red blood cells, white blood cells, thrombocytes, proteins, etc.
An animation of a multipolar neuron whose dendrites are growing.
A look inside a blood vessel. The so-called endothelium is a thin layer of endothelial cells that lines the inside of blood vessels. In the human brain, it also forms the blood-brain barrier.
