FAQs
"The search for answers is the essence of human existence."
— Marcus Aurelius
Would you like to produce your own film in 3D, but you feel like there are more questions than answers? Don't worry; everyone's been there ;)
That's why in the near future, the Frequently Asked Questions section will evolve into a proper, frequently updated blog for beginners in 3D film production.
Until then, have a look at the basic topics explained below.
Motions explained
-
Motion files, often known as motion capture (mocap) files or animation files, contain data capturing motion and action sequences, transferring that information from real-time recordings of actors to a 3D character of your choosing.
-
Motions are captured by recording real-life actors using specialized equipment.
The raw data from these recording sessions needs to be corrected, eliminating any errors that may have occurred during recording, and adjusted to fit a dedicated virtual skeleton (rig) of a 3D character. This ensures compatibility and prevents discrepancies in the behavior of your 3D character compared to the original motion.
-
Absolutely. Native rigs present in individual 3D softwares can have significant differences.
These variations may include the total number of virtual body bones, their names, the rules governing relationships between them, or how they relate to motion files.
-
Yes, Unreal Engine 4 and Unreal Engine 5 have their own 3D characters known as Metahumans.
These characters come with their own rigs, and these rigs are fully compatible with the Unreal Engine 4 and 5. Although the rigs are different, the motions used for any of them will work on other. Tested.
Furthermore, all users who register an account on the Epic Games (this registration is free) gain access to the free MetaHuman Creator.
This web-based editor allows you to create your own 3D characters for use in your Unreal Engine 4 and 5 projects. This is just one of the reasons why the Human Capture library focuses its motions on Unreal Engine.
-
The best practice to save you time is to use motions specifically designed for Metahumans, such as those available in the Human Capture library.
It's crucial to always check the compatibility of any motion with the 3D characters you intend to animate. Incompatible motions may lead to motion errors, visible in the overall body posture or in specific body parts (e.g., fingers, arms, posture) of your MetaHuman.
-
Yes, they will, but you might still encounter some compatibility issues with your individual character. These issues may arise when there are significant differences between the archetypes of the models in the motion files and your own character.
For example, using a motion sequence of a person scratching their belly, captured and adjusted to an average-weight person, may result in the character's hand disappearing into an obese person's belly. In such cases, you'll need to adjust the hand to fit the individual attributes of your 3D character. Currently, this aspect of potential differences is unavoidable when using ready-to-use motions, like those from the Human Capture library.
Human Capture motions
-
Human Capture utilizes specialized third-party equipment to capture the movements of real actors.
The raw motion capture (mocap) data then undergoes Library’s original workflow, which involves removing any errors from the capture process and ensuring full compatibility for use with MetaHumans in Unreal Engine 5.
-
First and foremost, the motion sequences in the Human Capture library cover full-body motion, including gestures, and - what makes this library unique - facial expressions.
Furthermore, all motion files are designed in formats that are ready to be used directly with MetaHumans in Unreal Engine. This means there's no need for you to convert or translate these motions to fit MetaHuman rigs (when your characters are based on body with average height and normal weight archetype). All you have to do is copy the motion files into your project and you’re ready to go.
If your MetaHuman character is based on different body archetype, you will have to proceed with quick and easy setup to make it compatible and avoid body deformations. Don’t worry, each downloaded pack has quick guide which will take you step by step through the whole process.
That's not the end of it. To make things even more convenient for you, each package in the library contains mirror-reflection body motion files. This provides a significant advantage when directing your 3D character's motion. For example, if you've selected a motion sequence where a person is turning left, you can use the mirror-sequence file to have your 3D character turn right.
-
All motion sequences in the library are offered in compressed to .zip format packages (sets). Each package contains either 12 motion sequences or a total of 120 seconds of motion, whichever comes first.
Detailed information about the individual number of motion sequences and the total duration of motions in each package can be found on the cover in the library and in the description of each package.
For your convenience, each downloaded package includes an attached .mp4 video file that provides a preview of the motions. This allows you to easily check the specific motion sequences you have access to without having to go back to the library. The video preview is exactly the same as the one you'll find on the description page of the downloaded package in the library.
In every package, you'll also find a .pdf file containing the End User License Agreement, which outlines the extent of rights granted to you after purchasing the motion package. If you want to review the precise rights you'll be granted, please visit the Human Capture EULA.
-
The workflow within Unreal Engine requires 2 separate files to fully animate MetaHumans. One file contains the complete body motion, including gestures, while the other contains mockup data for facial motion, essential for animating your MetaHuman's expressions.
This is why each motion sequence in the package is divided into separate files, named in a way that makes it easy to identify their purpose:
Files ending with "Body" contain the full-body mockup data for each motion sequence, including gestures.
Files ending with "BodyM" contain the mirror reflection of the full-body mockup data from the files ending with "Body".
Files ending with "Face" contain the mockup data for facial expressions for each motion sequence in the package.
-
In each motion package, every motion filename begins with 3 letters followed by 5 digits. This naming system was implemented to facilitate navigation when dealing with multiple files, particularly when they're arranged in alphabetical order.
The first 3 letters indicate the gender of the actor for whom the motion was originally intended. "FEM" indicates female, while "MAL" indicates male.
The subsequent 5 digits following the gender indicator represent a unique motion sequence number. This numbering is essential for identifying the body motion and facial mimicry files within each individual motion sequence.
-
All motions are in .fbx files calibrated for newest Epic Games MetaHuman (body and face). This gives you the benefit of easy process of importing motions to your project and avoiding any problems with translating mockup data to MetaHuman rig.
-
Absolutely! There's an essential distinction in how to interpret the fps speed in mockup data as compared to linear video.
In motion files, the fps speed tells you the number of position “snapshots” (inc. XYZ space and rotation) taken for each "bone" of the 3D character rig per second. When a motion is marked as 24fps, it means there are 24 such snapshots for each second of motion. Unreal Engine 5 handles the reinterpreting of this mockup data, regardless of the fps speed you choose in your animation sequence or when changing the motion sequence speed within the Unreal Engine 5 Sequencer.
So don’t worry, the typical problems encountered when changing fps speed in linear film sequences won't occur in this case.
-
Human Capture motions are designed to be fully compatible with the new generation of MetaHumans. Additionally, you can still use them with previous generations of MetaHumans without encountering any major problems.
However, it's essential to consider that the exact compatibility of the motion sequence with your specific MetaHuman may vary based on the body archetype of your MetaHuman and how it differs from the model that the individual motion was created for. If there are significant differences in height or weight between your MetaHuman and the reference model in the motion library, you may need to edit the motion to adjust it to your MetaHuman's individual posture.
This adjustment usually becomes necessary when the archetypes differ. Unless stated otherwise in the individual package description, all motions are prepared for instant use with average height and normal weight body archetype..
-
Human Capture motions are specifically designed for use with newest MetaHuman in Unreal Engine. Each motion is made to meet the compatibility requirements of Unreal Engine 4 and 5.
It's important to note that no consideration was given to any other 3D engines during the production of the final motion sequences so it would require individual calibration to your humanoid rig if you work in other 3d engines.
-
Human Capture primarily focuses on providing motions suitable for 3D film productions. So you may expect a wide range of motion sequences, from general activities that can be used in various contexts and film genres, to specialized contextual sequences like the 'Interrogation' or 'Walk in the Space' packages, which are designed to fit specific film scenes and play distinctive roles in film dramaturgy.
Human Capture consistently expands the variety of motions available over time, ensuring that you have access to as many different contexts as possible.As your feedback on the motions in the library values; if you'd like to share your thoughts, please feel free to do so here.
-
At first glance, you might think they look similar. However, it's important to understand that there's no one single way to stand, sit, or perform any activity. Replicating the exact same motion in crowded scenes within your production could make your actors seem like non-playable game characters (NPCs).
To avoid this effect and enhance the natural feel of motion in your 3D film production, the Human Capture offers different variations of similar motions. This approach gives you the freedom to choose the number of characters in a scene while maintaining a more authentic and diverse cinematic experience.
-
Absolutely! As you read this, new motions are being prepared for release in the near future.
Since Human Capture is a newly established library, it currently operates with a limited production capacity. Up to this point, you can expect the addition of 1-2 new motion packages per week.
As Human Capture continues to grow, these numbers will also increase, offering an even broader selection of motion options.

Licensing & Legal
-
When you purchase our motions, you are granted a comprehensive license for both commercial and non-commercial use, covering various creative projects, such as films, games, VR, and AR experiences. This license has no limitations in terms of time or project count.
Additionally, you have the right to edit, modify, cut, and mix the motions to suit your needs. If you buy the motions without registering a User Account, the license is limited to single-seat use, meaning only you can use the purchased motion.
If you purchase the motions as a registered user with a User Account in the library, your license extends to cover two additional seats. This is beneficial for collaborative scenarios within the same organization. Even if your coworkers don't work on the exact same project as you, they can still utilize the motions under this license.
For independent 3D creators, registering a User Account with Human Capture allows you to share purchased motions with two other collaborators, as long as they are actively working with you on the same project.
For a more in-depth understanding of the license terms, please refer to the Human Capture End User License Agreement (EULA).
-
You are not permitted to redistribute or resell motions as motion assets to any file format or engine. Neither unedited, unconverted, edited nor converted.
For details about that, go to Human Capture EULA.
-
You are granted exactly the same license with the same scope of rights and applying conditions as with your purchased motions. It means that even though the motion pack is for free, you still may use it in commercial projects, too.
For further details, go to Human Capture EULA.
-
First of all, please note that the MetaHumans seen in preview videos are not included in the pack of motions. Human Capture doesn’t own the rights to MetaHumans, as the entire scope of rights belongs to Epic Games.
But if the question refers to replicating the face features of Human Capture reference models used in previews, feel free to do so in your MetaHuman Editor. It won’t be understood as a breach of intellectual rights or copyrights, as long as it won’t be used in a manner of misleading other users to communicate with them as a Human Capture motion library. That kind of use would require written consent from Human Capture.
For further details, please refer to Human Capture EULA.
-
In the Human Capture EULA, videos with previewed motions on MetaHuman models are considered as "Other Content." It means that Human Capture doesn't own the full scope of rights here. Therefore, the best use would be limited to editorial purposes. If you want to use these files in your blog, YouTube channel, or any other social media account with a clear reference to the Human Capture library as the origin of such a file, then you can do so, as it doesn’t breach third-party rights. Any other use is prohibited and - again - limited to editorial rights.
For further details, please refer to Human Capture EULA.
