Working with the Smooth 4 Manual: What Actually Happens When You Try It
I spent about three weeks going back and forth with the Smooth 4 Manual before I figured out where it actually helps and where it's basically useless. Most people buy the gimbal, flip it on, and assume everything will work fine. It doesn't. Not immediately anyway. The Smooth 4 Manual mode is one of the three operational modes on the DJI Ronin-4S equivalent (the Osmo Smooth 4). In this mode, the gimbal motors are locked into fixed positions. No auto-leveling. No follow mode. You turn the dial and the gimbal physically follows your hand movements, but it does nothing on its own. It sounds like a limitation but it's actually the most useful mode for certain shots once you understand the mechanics.
How to Access Smooth 4 Manual Mode Properly
Flip the mode switch on the handle to the leftmost position (marked M). Press and hold the trigger halfway until you hear the motors engage and then disengage. You'll feel a slight shift. That's the confirmation that the gimbal has entered manual override. If it doesn't respond, check your battery. The Smooth 4 Manual mode requires a solid 100 percent charge to maintain motor tension. I've had it refuse to engage at 67 percent because the system thinks it can't hold the load. Once you're in manual, the three axes — pitch, roll, and yaw — respond directly to physical movement of the gimbal body. There's a small amount of resistance built into the servos so it doesn't feel completely loose. If it feels overly stiff or completely dead, recalibrate the motor torque through the app first. The calibration menu is under Gimbal Settings > Motor Torque. Set it to Auto and let it run. This takes about 30 seconds per axis. I've skipped this step before and wasted an entire day wondering why my pans were jerky.
When Smooth 4 Manual Actually Makes Sense
It's not a daily-use mode for most people. But when you need frame-by-frame control over camera movement — like matching a specific pacing in a edit — Manual mode gives you something Follow or FPV mode never will. You set the shot, hold the gimbal steady, and move it exactly how you want without the software second-guessing your input. I used Smooth 4 Manual for a sequence where I needed to tilt down exactly 15 degrees over four seconds. The gimbal held that movement frame-perfect because nothing was auto-correcting. In Follow mode, the software would have compensated for micro-tremors and ruined the timing. The tradeoff is obvious: every shake in your hands becomes a shake in the footage. If your grip isn't solid, the video looks like it was filmed during an earthquake. I learned this the hard way on a project where I forgot to brace my elbows against my ribs while panning. The resulting footage looked like a cheap found-footage horror film. I ended up rebuilding the entire shot.

Common Problems and What I Did About Them
One issue that comes up constantly with Smooth 4 Manual is motor drift over time. After about 20 minutes of continuous use, you'll notice the camera slowly tilts upward on the pitch axis even when you're holding the gimbal perfectly still. The fix is straightforward but most people miss it. Go into the app and enable Anti-Drift Compensation under Gimbal Settings. It's toggled off by default and the manual doesn't mention it in bold or anything, which is frustrating. Once enabled, the gimbal applies a micro-adjustment every few seconds to keep the horizon level. It adds about 5 percent latency to your inputs but eliminates the drift entirely. Another problem is uneven motor resistance between axes. Some users report that the yaw axis feels tighter than pitch. This usually means the gimbal head isn't balanced correctly. Loosen the tension knob on the quick-release plate, slide the camera forward or backward until it stays level when you release it, and retighten. I've seen people spend an hour fighting with motor settings when the real issue was a camera positioned two centimeters too far back on the plate.
Limits You Need to Accept
The Smooth 4 Manual has real bottlenecks. The maximum rotation speed in manual is roughly 90 degrees per second. That's fine for slow intentional moves but it makes fast whip pans impossible. The motors will complain and the gimbal will enter protective mode, pausing for about five seconds before resuming. You can't bypass this. It's a firmware-level safeguard. Also, there's no way to save or replicate a manual movement pattern. If you nail a perfect pan in Smooth 4 Manual, you can't replay it. You have to do it again. This matters if you're shooting multiple takes and want consistency. I've had to redo the same shot four times because I couldn't trust myself to match the exact speed on repeat attempts. If you need reproducible movements, look at the Smooth 4 App Control mode instead. It lets you input pan speeds and durations digitally. The tradeoff is slightly less organic movement, but for scripted work that's usually acceptable.
A Few Things the Manual Doesn't Tell You
There's a lock mechanism on the pitch axis that you can engage when transporting the gimbal or when you need it completely still for longer than a minute. It's a small lever on the back of the gimbal head. Engage it and the pitch motor disengages fully. This reduces power consumption noticeably. I keep it engaged between takes when I'm doing handheld work and it extends battery life from about 7 hours to closer to 9 hours. The official documentation mentions it in passing on page 43 but doesn't explain the practical benefit. Another thing worth knowing: the Smooth 4 Manual mode responds differently depending on whether you're holding it in portrait or landscape orientation. In portrait, the pitch axis becomes the primary movement axis for framing, which some shooters find more intuitive for following vertical subjects like people walking. In landscape, the yaw axis dominates. Neither is wrong. It just affects your muscle memory if you switch between orientations frequently. If you want the full documentation, the official PDF is available on the DJI website. Search for Smooth 4 Manual in their support section and you'll find the complete 60-page guide. The quick-start sheet alone won't cover most of what I just described. Don't skip reading past the first five pages.
