Record Video

The Record Video dialog captures screen recordings of Volvicon views. Use this feature to create animations for presentations, training materials, quality documentation, or sharing analysis workflows with collaborators.

Dialog Overview​

The Record Video dialog provides:

  • Target Selection: Choose what to record (application, layout, 3D view, or 2D views)
  • Animation Controls: Configure automatic rotation or slice scrolling
  • Quality Settings: Select video resolution and frame rate
  • Output Path: Specify the destination file
  • Recording Controls: Start, pause, and stop recording

Recording Targets​

Select what portion of the application to capture:

TargetDescription
ApplicationThe entire Volvicon application window
Scene LayoutThe current multi-view layout panel
3D ViewThe active 3D render view only
Sagittal/RightSagittal slice view with slice scrolling animation
Coronal/FrontCoronal slice view with slice scrolling animation
Axial/TopAxial slice view with slice scrolling animation
note

Target labels may vary based on the scene orientation type (Medical vs. Engineering conventions).

Animation Options​

Each target type offers specific animation capabilities:

Application and Layout Recording​

For application and layout targets:

OptionDescription
3D View RotationAutomatically rotate the 3D view during recording
Rotation DirectionPitch, Roll, or Yaw
Angle per FrameDegrees to rotate per captured frame
ReverseReverse the rotation direction
Slice ScrollingScroll through slices in visible 2D views
Slice RangeMinimum and maximum slice indices
ReverseScroll from max to min instead of min to max

3D View Recording​

For 3D view target:

OptionDescription
Enable RotationToggle automatic 3D rotation
Rotation DirectionPitch (vertical), Roll (tilt), Yaw (horizontal)
Angle per FrameRotation speed in degrees
ReverseReverse rotation direction

2D View Recording (Sagittal, Coronal, Axial)​

For 2D slice view targets:

OptionDescription
Enable Slice ScrollingToggle automatic slice navigation
Min SliceStarting slice index
Max SliceEnding slice index
ReverseScroll from max to min

Video Quality Settings​

SettingOptionsDescription
QualityAuto, Native, UHD 4K, Full HD, HD, SD, LowOutput resolution preset
FPS1–240Frames per second

Quality Presets​

PresetResolutionUse Case
AutoAutomatic selectionGeneral purpose
NativeMatch current view sizeBest quality for the view
UHD 4K3840 × 2160High-resolution displays, large presentations
Full HD1920 × 1080Standard HD output
HD1280 × 720Web sharing, smaller files
SD720 × 480Legacy compatibility
Low640 × 480Smallest file size
tip

For smooth playback, match the FPS to your target player's expected rate (typically 30 fps for presentations, 60 fps for smooth animation).

Additional Options​

OptionDescription
Record Mouse CursorInclude the mouse pointer in the recording

Enable cursor recording when creating tutorials or demonstrating interactive workflows.

Workflow: Recording a Rotating 3D View​

  1. Set up the 3D view with the desired camera angle and visible objects
  2. Open File → Record Video
  3. Select 3D View as the target
  4. Enable 3D View Rotation
  5. Choose rotation direction (e.g., Yaw for horizontal spin)
  6. Set Angle per Frame (e.g., 1–3 degrees for smooth rotation)
  7. Set Quality to Full HD and FPS to 30
  8. Click Browse to select the output file location
  9. Click Record to start
  10. Wait for a complete rotation (or desired duration)
  11. Click Stop to finalize the video

Workflow: Recording a Slice Scroll-Through​

  1. Load the volume and adjust window/level as desired
  2. Open File → Record Video
  3. Select the slice view target (e.g., Axial/Top)
  4. Enable Slice Scrolling
  5. Set Min Slice to 0 and Max Slice to the last slice
  6. Choose whether to Reverse the scroll direction
  7. Set Quality and FPS
  8. Specify the output path
  9. Click Record to start
  10. Recording automatically progresses through slices
  11. Click Stop when complete

Workflow: Recording Application Workflow​

  1. Prepare the application state for the starting point
  2. Open File → Record Video
  3. Select Application as the target
  4. Enable Record Mouse Cursor if demonstrating interactions
  5. Optionally configure 3D rotation or slice scrolling if applicable
  6. Click Record
  7. Perform the workflow actions you want to capture
  8. Click Pause if you need to set up the next step
  9. Click Stop when finished

Output Format​

Videos are encoded using H.264 codec and saved as:

  • MP4: Modern, widely compatible format
  • AVI: Alternative container format

The output maintains aspect ratio when resizing to the selected quality preset.

Best Practices​

Before Recording​

  1. Set up the view: Position camera, adjust visibility, configure window/level
  2. Close unnecessary dialogs: Keep the recording area clean
  3. Verify disk space: High-quality recordings can produce large files
  4. Test with a short recording: Verify settings before long captures

During Recording​

  1. Minimize interruptions: Avoid opening dialogs or switching applications
  2. Use pause strategically: Pause to set up next steps in tutorials
  3. Monitor progress: Watch the recording to catch issues early

After Recording​

  1. Verify the output: Play the video to confirm quality and content
  2. Trim if needed: Use external video editing software for refinement
  3. Compress for sharing: Consider transcoding for web or email sharing

Troubleshooting​

Video File Is Very Large​

  • Lower the quality preset
  • Reduce FPS for slower animations
  • Shorten the recording duration

Recording Is Choppy or Drops Frames​

  • Lower the quality preset to reduce processing load
  • Close other applications to free system resources
  • Reduce the complexity of the visible scene

Animation Speed Is Too Fast or Slow​

  • Adjust the Angle per Frame for rotations
  • Adjust FPS to change overall playback speed

Output Path Cannot Be Written​

  • Verify write permissions for the output folder
  • Check available disk space
  • Ensure the filename is valid
