🎬 Recording Your Swing
LVPro-DSM offers three recording modes to capture your swing. We recommend using AI mode to capture and play swings back automatically.
⚙️ Finding the Settings Menu
Main Screen
Settings MenuAI Mode (Recommended)
Uses pose detection to recognize your golf swing and automatically trigger recording at impact. This is the easiest way to capture your swing hands-free.
AI mode works best with a clear view of the golfer against a simple background. Ensure good lighting and minimal obstructions.
How AI Recording Works
When AI mode is active, a status icon appears next to the record button showing exactly what the AI sees. Both the button color and status icon change together as the AI progresses through detection.
Not Detecting
Person Found
Ready
Recording
When AI mode is selected in Settings, you'll see the brain icon on the recording button. The button starts red with an eye-slash icon, indicating AI is actively looking for a person.
When you step in front of the main camera, you'll see a pose skeleton overlay tracking movements in real-time. When the button turns orange with a person icon, someone has been found in the frame and the AI is analyzing their movements.
The Main camera must match your AI settings (Front Facing/Down-the-Line and Right/Left handed) for accurate swing detection.
When you address the ball, the button turns green with a checkmark icon. The AI has identified a golfer in their setup position and is ready to record. Take your swing naturally—the AI will automatically trigger at impact.
When a swing is detected, the recording indicator shows a countdown. The app automatically:
- Records the configured seconds before and after impact
- Trims the video to your swing
- Downloads and prepares for instant replay
Your swing video will appear automatically for review—no button presses needed!
AI Settings
Golfer Handedness
Select whether you swing left-handed or right-handed. This helps the AI understand your swing direction.
🫲 Left-Handed
For golfers who swing from the right side of the ball
🫱 Right-Handed
For golfers who swing from the left side of the ball
Camera Perspective
Tell the AI where your camera is positioned relative to the golfer:
→ Down-the-Line
Camera behind the golfer, looking down the target line. Shows swing plane and path.
👤 Front View
Camera facing the golfer (face-on). Shows weight transfer and rotation.
Capture Duration
Set how many seconds to capture before and after the detected impact (1-5 seconds each). Longer durations capture more of your backswing and follow-through.
Other Recording Modes
Manual Mode
Full control over when recording starts and stops.
- Press the record button to start
- Press again to stop, or let it auto-stop after the set duration
- Best for: Practice sessions where you want to capture multiple swings
Sound Trigger Mode
Automatically captures your swing when it detects the sound of impact.
The app continuously buffers video. When it hears the impact sound, it saves footage from before and after the trigger moment—ensuring your complete swing is captured.
Settings:
Sensitivity tip: Lower values (toward -60) trigger on quieter sounds; higher values (toward -20) require louder sounds. Start around -40 dB and adjust based on your environment.
▶️ Reviewing Your Swing
Playback Controls
After capturing a swing, use these controls to analyze your technique:
Playback Speed
Watch your swing in slow motion to see details invisible at full speed:
| Speed | Best For |
|---|---|
| 0.2x | Detailed analysis of impact, club face angle, and ball contact |
| 0.5x | Observing swing tempo, transition, and sequencing |
| 1.0x | Viewing natural rhythm and overall swing |
Loop Count
Set how many times the video automatically replays (0-10 loops). Set to 0 for single playback, or higher values to watch the same swing repeatedly without touching your iPad.
Video Scrubber
The scrubber bar lets you navigate through your recorded swing:
- Drag anywhere on the progress bar to jump to that moment
- Live preview shows the frame as you drag
- Video automatically pauses when you start scrubbing
Frame-by-Frame Controls
For precise analysis, use the frame buttons below the scrubber:
- ⏮ Back Frame — Step backward one frame
- ⏭ Forward Frame — Step forward one frame
Dual-Camera View
When recording with two cameras, scrubbing or stepping frames on one view automatically updates the other, so you can compare the same moment from both angles.
Video Synchronization
Videos from two cameras may occasionally get slightly out of sync. This happens because of minor timing differences when each camera receives the recording trigger command. LVPro-DSM includes a Sync Offset control to perfectly align your dual-camera playback.
Look for the ↔️ (arrows) icon in dual-camera playback mode. This opens the Sync Offset scrubber, which lets you shift the secondary video forward or backward to match the primary video.
How to synchronize videos:
- Tap the ↔️ sync icon to open the Sync Offset scrubber
- Drag the slider left or right to shift the secondary video timing
- Use the frame step buttons for precise single-frame adjustments
- The offset displays in both seconds and frames (e.g., +0.033s = +1 frame)
- Tap Reset to return to zero offset
Tip: Find a moment where both cameras capture something distinctive (like impact), then adjust until the frames align perfectly. The offset is saved automatically for that recording.
🎯 Focus Mode
Focus Mode automatically slows down playback through the impact zone—the most critical part of your swing—while playing the rest at normal speed.
How It Works
- Video plays at your normal speed (1.0x)
- When playback enters the Focus Zone, speed drops to ultra-slow motion
- After the Focus Zone, playback returns to normal speed
See your impact in extreme slow motion without waiting through the entire backswing. Perfect for analyzing club-ball contact, face angle at impact, and follow-through position.
Focus Zone Settings
Enable Focus Mode
Toggle Focus Mode on or off in Settings → Focus Mode, or tap the Focus button during playback.
Focus Duration
How long the slow-motion zone lasts (0.2 to 2.0 seconds). increasing Focus Duration will increase the total playback time.
Focus Speed (FPS)
How slow the video plays inside the Focus Zone. Lower FPS = slower motion.
Example: At 5 fps, you see only 5 frames per second instead of the original 120—making motion appear 24× slower during the focus zone.
Impact Point Adjustment
If the focus zone doesn't line up with your actual impact, adjust the Impact Point to shift the zone earlier or later in the video.
The display shows offset from the trigger point: At Trigger means centered on impact, +0.3s means shifted slightly after, -0.2s means shifted slightly before.
Focus Zone Scrubber
For precise control, open the Focus Zone scrubber during playback:
Adjusting the Focus Zone
- Drag the green dot to set where slow motion begins
- Drag the red dot to set where slow motion ends
- Yellow area shows the current focus zone
- Video seeks to the dragged position for live preview
Fine-Tuning with Frame Controls
Below the scrubber, use the arrow buttons for frame-by-frame adjustments:
- Green arrows — Move the start point by one frame
- Red arrows — Move the end point by one frame
Set your start point just before the club reaches the ball, and end point just after impact. A 0.3-0.5 second zone at 3-5 fps gives excellent detail without making playback too long.
