One swing. Two angles. The LVPro2 Dual Camera system captures front and down-the-line at the same time and streams both to your iPad live. In this guide we'll cover two features that make that footage genuinely useful: live dual camera synchronization — keeping the two angles locked to the same moment in the swing — and Focus mode, which automatically slows the video down through impact so you can actually see the fastest part of your swing.
Why live dual camera sync matters
With a dual-camera setup, both cameras are recording the same swing — but they're sending that video to your iPad wirelessly. Wireless video is subject to network jitter and latency, so the two streams don't always arrive perfectly in step. Left uncorrected, your front view might be a few frames ahead of (or behind) your down-the-line view, which makes comparing the two angles misleading.
Live dual camera synchronization is how you bring the two angles back into the same instant in time, so that when you reach impact in one view, you're looking at impact in the other view too.
Before you record: use a fast Wi-Fi router. For reliable synchronization we strongly recommend a fast Wi-Fi router. The cleaner and faster your network, the more consistent your sync will be from capture to capture. The noisier the network, the more the synchronization will drift between swings.
How to synchronize your dual camera videos
- Record your swing. Both cameras capture front and down-the-line simultaneously and stream the footage to the LVProDSM app on your iPad.
- Open the swing in playback. Both angles are ready to review together.
- Use the offset controls to line the angles up. Nudge one stream forward or back until a shared reference point — the moment the club starts down, or the instant of impact — matches in both views.
- Scrub through the swing to confirm. Move through the swing and check that key positions stay aligned across both cameras.
Set a default network offset (do this once)
Here's the time-saver. Because most of the misalignment comes from your local network latency — which tends to be fairly consistent on a given router — you don't have to re-sync from scratch every time.
Once you've recorded your first video, use the offset controls in playback to set a default network offset that reflects your local network's latency. From then on, new captures start out much closer to being in sync, so you'll have far less adjusting to do swing after swing.
Keep in mind: the default offset is a baseline, not a lock. Network jitter still varies slightly capture to capture, so you may need a small touch-up on any given swing. The faster and quieter your Wi-Fi, the smaller those touch-ups will be.
Focus mode: see the fastest part of your swing
The clubhead is moving at its absolute fastest through impact — which is exactly the moment that's hardest to see at normal speed. That's the problem Focus mode solves.
Focus mode automatically reduces the frame rate through impact to show that section in slow motion. Because the club is travelling fastest right there, slowing it down lets you clearly see what's happening at the most important — and most fleeting — point in the swing.
Best of all, it's automatic and hands-free. You don't have to find impact, set markers, or fiddle with playback speed. Focus mode detects the moment and slows it down for you, so you can spend your attention on the swing instead of the controls.
Putting it together
Live dual camera synchronization lets you compare two angles of the same instant. Focus mode makes the most important instant — impact — slow enough to actually study. Used together on a fast Wi-Fi network, they turn two raw camera feeds into a clear, slow-motion picture of your swing from both angles at once.
