Top 8 Most Popular Motion Capture and Animation Software
There’s a slight misconception of what gets classified as motion capture software and what software is simply used for animation (mocap animation included!). To keep things simple in this article, we’ve categorized mocap software into two distinct groups:
- Specialty software to record and edit motion capture, that is directly influenced by which of the mocap tools you choose (e.g., if you choose Rokoko’s Smartsuit Pro, you’ll need to work with Rokoko Studio).
- 3D content creation software or game engines to import, edit, animate, and render motion capture
In this article, we’ll focus on the various workflows you can use to import your motion capture data into multiple types of 3D software, falling into the second category. Each option has its own strengths and weaknesses, though most animation artists tend to favor a specific software with time.
What is motion capture technology?
Motion capture is the tracking and recording of human movements into animation software. You can use motion capture for 3D or CG projects that need realistic character movements. The primary benefit of motion capture is the speed of animation. Instead of laying out hundreds of keyframes and spending a long time tweaking animation, you can throw on a motion capture suit and record the animation you need in 15 minutes flat. This shaves hours from any animator’s timeline. Common applications include:
- Character animation for games
- Previs for live-action, animation, or events
- Animation for films or videos of any length
- Virtual reality projects
Motion Capture Pipeline Options
There are three distinct workflows for mocap, and each suits different types of productions. Which one you choose depends on your resources and your output requirements. You also need to understand that motion data is recorded in multiple files, sometimes coming from different applications that have different export or streaming standards. For example, if you record facial expressions using motion capture, you’ll need to import that animation data separate from the human body motions.
Workflow #1: Use existing motion assets
You don’t have to buy a mocap suit to use motion capture animation in your scene. Identify the type of animation you need for your character and download a pre-made motion capture asset. You can export the motion capture to the 3D software of your choice and quickly retarget the animation onto your rig. You can download pre-recorded motion capture animation assets from Rokoko’s Motion Library. It’s the largest resource of existing motion capture and is frequently updated by professional creators. Get 100 assets for free when you sign up and $3-$6 per asset after that.
Workflow #2: Record custom animations and import them into your software of choice
For this workflow, you’ll need a mocap suit such as Rokoko Smartsuit Pro and the accompanying motion capture software called Rokoko Studio. Record the animation to the supplied armature and export as an fbx file or compatible file type. Import the animation into your scene and retarget it to your rigged character mesh. And just like that, your mocap is applied.
Workflow #3: Live stream mocap data directly into your 3D scene
This workflow is mainly similar to the workflow above, but instead of recording and exporting, you link your mocap software to your 3D software instead of recording and exporting. When done correctly, it should live stream directly into your scene for recording or rendering. If you use a 3D engine that’s capable of real-time rendering like Unreal Engine, you can stream your animation directly to social media (see VTubing).
What software should you use for your 3D animation project?
Good question! If you currently use one of the software listed below and are happy with its performance, I recommend skipping down and checking out the accompanying mocap tutorial. If you’re not currently invested in one of the software solutions below, give a read-through of the pros and cons to decide which one you should get started with. There’s no real wrong answer — it comes down to the requirements of your project and your personal preference and willingness to learn tools with different learning curves. Each listed software integrates with Rokoko’s motion capture system and can apply facial movement, live performances, and finger tracking to your animated character.
Free open-source software that’s widely used on indie projects of all types. Thanks to its reliable integrations, it’s one of the most popular software to use with any mocap system. Learn more about using Blender for motion capture here.

- Great toolset for high-end productions
- Considered the best software for character animation
- Can be overwhelming for beginners
- Not a great option for low-polygon models
- Resource-hungry on your computer
Unreal Engine used to be just for video games, but it’s evolved into something so much more. Thanks to its real time rendering and live streaming capabilities, it’s being used extensively for virtual production and virtual event previsualization. Learn more about using Unreal Engine for motion capture here.

Motion capture software is there to simplify the animation process
While motion capture animation doesn't altogether remove the need for animation, it dramatically simplifies the character animation process. Easy to use tools like Rokoko’s Smartsuit Pro are what you should look for if you’re aiming to record animation, apply it to your character, and render your scene all in one day’s worth of work.
