CUSTOM AVATAR
Custom avatar motion capture
Prepare reusable custom avatar targets for AIMoCap so source video can drive your own character workflow.
For teams searching for motion capture on a custom avatar.
Short answer
Custom avatar motion capture means applying solved video motion to a prepared and published avatar target, not uploading a character during every job.
When to use AIMoCap
Use AIMoCap when a team needs repeated mocap jobs on the same prepared character and wants Studio review before download or downstream cleanup.
When not to use AIMoCap
Do not use this path when the avatar is still a draft, when binding has not been tested, or when Default output is enough.

Custom avatar motion capture is about target reuse. The same prepared character can be selected again after upload, pose review, binding, retarget testing, and publish.
This is different from generic video-to-FBX output because the motion is evaluated on the team's own avatar.
The page should remain focused on repeatable character workflows rather than repeating the entire mocap product pitch.
For teams, the useful question is operational: is this avatar ready for the motions we actually record, and do we know what to inspect when a job looks wrong?
Custom avatar motion capture facts
- Published custom avatars can be selected as reusable Studio targets.
- A draft avatar should not be used as if it were a stable target.
- Custom avatar output and Default FBX output answer different workflow needs.
- For custom avatar motion capture, character proportions can change foot contact, shoulder arcs, and reach distance even when the solved motion is the same.
- Source-video quality still matters even when the avatar has been prepared well.
- A useful custom-avatar review separates target setup issues from source-video issues so teams know whether to fix the avatar, rerun the clip, or clean up downstream.
- Repeated jobs on the same avatar should keep notes about the source clip, trim range, selected avatar version, and cleanup result.
- A custom-avatar result should be accepted only after checking limb mapping, scale, root orientation, foot contact, shoulder behavior, and whether the motion still matches the source performance.
- If multiple clips fail on the same avatar in the same way, the target setup is more suspicious than any one source video.
- A custom avatar motion capture workflow should compare at least three surfaces when debugging: source video, Default output, and custom-avatar output.
- Repeated jobs should keep avatar target version in the review note so a quality change is not confused with a source-video change.
- If the avatar is used for MMD, game engines, or stylized characters downstream, target acceptance should include that downstream context rather than only generic playback.
- A custom-avatar review should keep a Default baseline, custom-avatar output, avatar target version, trim range, export FPS, and cleanup verdict in the same note.
- When Default output is acceptable but the custom target is not, the likely issue is avatar setup, binding, scale, proportions, or target-version drift rather than the source clip alone.
- When both Default and custom-avatar outputs are poor, source-video readability, camera motion, occlusion, trim, or the base solve should be inspected before changing the avatar.

Custom avatar workflow concerns
Avatar-retargeting searches usually come from people who already hit a rig, rest-pose, scale, or cleanup problem. The page should explain how to diagnose target readiness instead of promising one-click character motion.
Upload success is not target readiness
Users searching for custom avatar motion capture often expect a character file to work immediately, but custom avatar motion capture should move through upload, A-pose review, binding, retarget test, publish, and only then repeated mocap use.
Most bad results have a debuggable source
When a custom avatar motion capture result looks wrong, the next question should be whether the source clip, rest pose, skeleton mapping, scale, or retarget test caused the problem instead of rerunning blindly.
Reusable targets matter when teams repeat shots
For custom avatar motion capture, the workflow becomes valuable when the same character is used across many clips; publishing a tested target prevents setup work from being repeated for every job.
Why this is not just video-to-FBX
Use these facts to decide whether this workflow matches your output, integration, and cleanup needs.
Character-specific review
Teams can inspect motion on the intended character rather than only on a generic target.
Reusable setup
For custom avatar motion capture, publishing turns upload, pose, binding, and retarget-test work into a reusable target for future Studio jobs.
Two quality inputs
Custom avatar motion capture quality depends on both the source video and the prepared avatar setup, so bad results should be debugged from both sides.
Debug split
Bad custom-avatar motion should be debugged by separating avatar setup, source-video readability, and downstream cleanup needs.
Acceptance checklist
The page should tell users what to check after a custom-avatar job, not only that the avatar can be selected.
Three-surface comparison
Comparing source video, Default output, and custom-avatar output gives reviewers a practical way to locate the failure layer.
Job-level verdict
Recording accepted, recapture, avatar-fix, or cleanup-needed verdicts makes repeated custom-avatar jobs easier to improve over time.
Baseline evidence
Keeping Default output next to custom-avatar output gives teams a practical control sample for every disputed custom-avatar result.
Versioned target evidence
A job note should identify the exact published target version so a later avatar replacement is not confused with a source-video change.
Custom avatar mocap workflow
Prepare the avatar once
Use character management to upload, pose-check, bind, retarget-test, and publish the avatar.
Select the published target
When submitting a mocap job, choose the published avatar if the result should be reviewed on that specific character.
Compare result quality
Review whether the source clip and avatar proportions produce acceptable motion before downstream cleanup.
Separate target issues from clip issues
Compare the same source on Default output and the custom avatar when needed, then decide whether the avatar setup, source clip, or cleanup layer is the problem.
Record job-level acceptance
For each reusable-avatar job, keep source clip, trim, selected target, export FPS, result verdict, and whether the fix belongs to avatar setup, recapture, or downstream cleanup.
Keep a Default baseline
When a custom-avatar result is questioned, compare it with Default output from the same source so reviewers can separate solved-motion quality from target-specific retargeting issues.
Common questions
Can I run mocap on my own avatar?
Yes, after the avatar is uploaded, bound, tested, and published as a reusable target.
Is a custom avatar job different from Default output?
Yes. Default output is generic animation-oriented output; a custom avatar job reviews motion on a prepared character.
Can a prepared avatar fix a bad source video?
No. Poor lighting, occlusion, or unclear motion can still reduce result quality.
What should happen before I reuse the avatar?
The avatar should pass pose review, skeleton binding, a retarget test, and publish so future jobs use a stable target rather than a draft.
How do I debug poor custom-avatar results?
Check avatar pose, skeleton binding, scale, root orientation, source-video clarity, trim range, and downstream cleanup notes separately before changing the whole workflow.
When should I suspect the avatar setup instead of the video?
Suspect the avatar setup when different source clips show the same limb swap, scale, root, shoulder, or foot-contact problem on the same published target.
What should I record for each custom-avatar job?
Record source clip, trim range, selected avatar version, export FPS, result verdict, and whether the next fix is recapture, avatar setup, or downstream cleanup.
How can I avoid wasting credits on a bad custom avatar?
Run representative acceptance clips first and pause repeated jobs if the same shoulder, hand reach, foot contact, or root problem appears across clips.
Why compare against Default output?
Default output is the control sample. If Default is good but the custom avatar is poor, inspect the target setup. If both are poor, inspect the source clip or base solve first.
What is the minimum review note for a custom-avatar job?
Record source clip, trim, export FPS, capture type, avatar target version, Default baseline verdict, custom target verdict, and whether the next action is recapture, avatar fix, or cleanup.
