How to shoot large-scale moving delay with Osmo

Lingmu Osmo has three-axis stable pan/tilt, 4K ultra-high-definition camera, mobile device preview and automatic time-delay shooting function, which can simplify the shooting process of time-delay photography to the greatest extent.

1. Install auxiliary equipment

Because the moving delay is very sensitive to the height change, in order to keep Osmo always on the same horizontal line, it can be fixed on a tripod, and a pulley is installed at the bottom of the tripod to facilitate moving.

2. Selection of moving path

When moving, we try to choose a reference pavement, such as floor tile or platform edge. This can keep the linearity of the moving path and estimate the moving distance conveniently.

3. Calculate the single-step distance

First, the total moving distance is estimated. For example, if the moving distance is 100 meters, we want to generate a video with a length of about 10 second, but there are 24 photos per second, and 240 photos need to be taken. Then the single-step moving distance is 100 meters divided by 240 frames, which is about 0.4 meters.

4. Set the viewing angle reference point

When moving, the subject tries to stay in the center of the picture, and the shooting angle on the camera always corresponds to a fixed point on the picture. We can set the camera grid to grid plus diagonal mode in DJI GO app, and always keep the reference point in the diagonal focus when moving.

5. Set the angle of view rotation.

We use a manual rocker to fine-tune the tilt angle. It should be noted that the product of the fine adjustment angle and the number of moving steps per step should be the total change angle. Adjusting the angle of translation axis and pitch axis will bring different perspective effects. If you feel that the fine adjustment angle of the rocker is too large, you can set the speed and smoothness of the Osmo pan-tilt rocker in the APP, and the reference range is 1~ 10.

6.DJI Go app Time Delay Shooting Settings

The locking mode of the pan-tilt is set to lock the pan-tilt direction, which can eliminate the horizontal vibration and vertical rotation deviation when moving. Finally, the parameters of Osmo are set according to the estimated path distance and video length.
