Are you looking to introduce medical device animation into your marketing? Do you want to know more about the medical device animation process?

Adding animations to your marketing can bring life to your message in a simple, new and creative way. But if you’re unfamiliar with the process of creating medical device animations this article is the right place for you.

Here we’ll explore the difference between a camera preview and the final render, a common question we’re asked during the animation process.

What is a camera preview?

In animation production, the camera preview serves as the final checkpoint before its sent to final render.

This is an important stage as it allows you to review your final animation before it is sent for rendering.

Often presented in black and white or with basic shading, it provides an opportunity to review timings, transitions and the overall flow of your animation before the final render.  Your animation team will likely also incorporate a test voiceover track (if you have a script accompanying your animation) so you can ensure it aligns perfectly with your animation.

If you have any concerns at this stage, be sure to communicate them to your agency, as what you see in the camera preview is what you will see in the final render, albeit in a much higher resolution and more vibrant colours.

What is a final render?

A final render is the ultimate version of your animation, processed through the render farm.

Simply put, rendering an animation is comparable to exporting a video on your laptop, but at a much higher quality.

As a rule of thumb, a 2.5-minute 3D animation can take up to 2 weeks to render, depending on the rendering power of your animation team’s render farm. Therefore, it is not something you want to undertake unless you are confident that your animation is correct – which is where the camera previews come into play.

Once your render is complete, all that remains is to record your final voiceover and incorporate any post-production elements into your animation, such as graphics like labels or subtitles, or music.

Why create camera previews?


Rendering animations, which can vary in duration and complexity, may take hours, days, or even weeks to complete. Due to the substantial time and computing power needed for their creation, a camera preview is generated, providing you with a low-quality version of your final animation.

This preview saves you the time of waiting for each version of your animation to render out.


Rendering your animation requires a significant amount of time and computing power, which comes with a not insignificant cost. That is why the final render of your animation is typically only done once, at the end of your project.

Creating camera previews allows you to watch a version of the animation that includes music, voiceovers, and movement while still being able to make timing edits without incurring high costs. This method ensures that the final version of your animation aligns precisely with your original plan, without totally blowing your budget and timeline.
