3. Toolbar: Foot Contact, Show Skeleton, Mirror, Inplace and Fullscreen - check the quality of your clip. → Toolbar

5. Player: current Time and Frame, Play/Pause, Stop, Loop, and Playback Speed.
6. Streaming: stream the clip to another app. → Live-streaming
7. Details: name, duration, frames, frame rate, actor and creation date of the clip.

Play a clip #

• Double-click a clip in the Clips list to open it.
• Click Play / Pause to play it, Stop to stop it, and Loop to repeat it.
• Drag the playhead on the timeline to jump to any moment.
• Change Playback Speed to play it slower or faster.

💡 Turn on Foot Contact and Show Skeleton in the toolbar to check foot grounding and joints in detail.

Trim a clip #

Trimming creates a new clip with only the part you need. Your original clip stays as it is.

1. Set the range#

   • Drag the left trim handle to where you want the clip to start, and the right trim handle to where it should end.
   • Trim in the Details panel shows the In, Out and Length of your range.
   • The player now plays (and loops) only within the range, so you can check it before you create the clip.

2. Click Create Trimmed Clip#

   • Click Create Trimmed Clip in the Trim section.
   • A new clip named [Clip Name]_trimmed is added to the list and opens.

Retarget a clip to a character#

Retargeting creates a new clip where your character performs the motion.

1. Choose a character#

   • In the Retarget section, select a character from Character.
   • Don't see your character? Click the Import Character button next to the list - see Import Character and Retargeting.

2. Click Create Retargeted Clip#

   • A new clip named [Clip Name]_retargeted_[Character] is added to the list and opens with the character.
   • Its Details now show the Character, plus two buttons:
     • Clip Retarget Settings: opens the same 5-step window as Import Character and Retargeting to fine-tune how the motion fits the character. Save to Clip changes this clip only.
     • Remove Character: removes the character from this clip.

Export a clip #

1. Choose a format#

   • In the Export section, open Format and choose:
     • BVH
     • FBX (Blender), FBX (Unity), FBX (Unreal) or FBX (MotionBuilder)

2. Click Export#

   • Click Export and choose where to save the file.
   • The notification shows [Clip Name] is exported when it's done.

• Duplicate it - a copy named [Clip Name]_(clone) is added.

Stream a clip #

• Open the clip, then click Start Streaming in the Streaming section of the bottom panel.
