Film Room

Ball data tells you what happened. Film Room tells you why.

Every shot is saved with the swing that produced it — two angles, frame-synced, with your body tracked through the motion.

Film Room: two synced camera angles with the skeleton overlay, the swing timeline, shot stats and an AI review.

Measured, not eyeballed

Spine, shoulders, hips, head, lead arm and knee — with the angle in degrees.

A review that argues from your numbers

Key frames and the shot go out; a written breakdown comes back.

Your swings on your phone

Open the Film Room on the web — both angles, synced, numbers alongside.

One complete workflow

From your first shot to a lower handicap.

A single loop that carries every session from the tee to the takeaway.

Questions before you download?

Do I need GSPro, and which launch monitors work?
Trundle is built specifically for GSPro, and works with every launch monitor GSPro does. It never talks to your launch monitor directly — it picks each shot up from GSPro once GSPro has recorded it. So whether you’re on Uneekor, SkyTrak, Mevo+, Bushnell, Garmin, FlightScope or Foresight, if the shot lands in GSPro it lands in Trundle, with nothing to reconfigure on the launch monitor side. Other simulator software (E6, TGC, Awesome Golf) isn’t supported today.
Does it change anything about my GSPro setup?
No. There is no mod, no plugin and nothing injected into GSPro — Trundle only reads the files GSPro already writes and captures its window the way any screen-capture tool does. It does need to run on the same PC as GSPro, side by side, which is the machine you already play on.
Do I still need OBS?
No. Scene layouts, camera sources, audio capture, streaming and recording are all built in — purpose-built for a golf bay instead of assembled out of generic sources. If you already have an OBS setup you like, Trundle can output as a virtual camera and feed straight into it.
Do I need a camera, and how many?
None at all for the data dashboard, round tracking and performance analytics — plenty of people run Trundle purely as a shot-data display on a second screen. One camera covers streaming and swing replay. Two — face-on and down-the-line — unlocks the Film Room’s synced dual-angle replay and the body-tracking measurements that need more than one view of you.
What kind of camera do I need?
Any USB webcam Windows recognises, plus capture cards and action cameras that present themselves as one. For swing replay, frame rate matters far more than resolution: 720p at 120fps is the sweet spot, and a 30fps camera will smear through impact no matter how many megapixels it has. Trundle lists the formats each connected camera actually supports, so you can check what yours can do before buying another one. If you run two high-frame-rate cameras, spread them across separate USB ports rather than one shared hub.
Where does my footage go? Is anything uploaded?
Everything is recorded to your own PC, and your full-quality clips stay there. Three things can leave it, all tied to your account. Sign in and your round history syncs so you can see it on the web (you can switch this off). On Pro you can turn on clip syncing, which uploads a small copy of each swing so you can watch it on your phone. It is off by default and private to you. Your most recent swings are kept, and the oldest are replaced as new ones arrive unless you star them. And AI swing analysis sends a handful of frames from the swing you asked about, only when you ask for it. Local clips are trimmed to the swing itself, and retention settings age old ones out so the folder doesn’t quietly grow forever. Full detail is in the privacy policy.
What are the system requirements?
Windows 10 or 11, 64-bit, on the PC running GSPro. In practice a machine that runs GSPro comfortably runs Trundle alongside it. For streaming and recording, a GPU with a hardware video encoder (NVIDIA NVENC, Intel Quick Sync or AMD AMF) is strongly recommended — Trundle uses whichever you have and falls back to CPU encoding if you have none. Encoding on that dedicated encoder is separate silicon from the part rendering GSPro, so it isn’t competing with your frame rate.
Is there a Mac version, or can I use just the website?
Trundle itself runs on the Windows PC with GSPro, because that’s where the shots, the cameras and the stream are. The website is the other half: sign in on any phone, tablet or computer, Mac included, and your rounds and stats are there, with your swings and their AI reviews on Pro. It shows what the desktop app captured, so it needs Trundle running on your sim PC to have anything to show.
Is there a free version?
Yes, and it isn’t a trial. The real-time data overlay, configurable scene layouts, swing camera replay, virtual camera output and session history are free, with no account required. Paid plans add streaming and recording (Creator), then the Film Room, AI swing analysis, your swings on your phone and long-term history (Pro) — those sign in with Google.
Can I cancel, and what if it isn't for me?
Cancel any time from your account page — you keep the paid features until the end of the period you have already paid for. And if it turns out not to fit your setup, any purchase is refundable within 14 days, no reason needed. See the refund policy.
