The video grab quality level of the best smartphones (up to 4K or 60 fps) is that each times more and more users, both personal and professional, who use this device as the main element of video grabbing.
If you are thinking about using your mobile phone to grab a bad video, you might want to buy a video stabilizer or gimbal. We tell you how these accessories work, what you want before you buy one of the best models you can get.
What is it? How does a video stabilizer generally work?
Despite the fact that our smartphone comes with optical stabilization you will get a fluid image and sudden movements in certain scenes. To reduce this limitation to the time of grabbing video is the stabilizers, which are becoming increasingly popular with users.
A video stabilizer or gimbal is basically an electro-mechanical system whose main purpose is to counteract the vibrations and / or unwanted movement that takes place in the camera and with the smartphone minds we grasp, and to soften the general movement of the camera.
The most economical functions work solely mechanically using sensors such as gyroscopes, and absorbing sudden movements. It usually based on three stabilization parts, each one controlled by a motor.
The different sensors in the system generate a weekly signal with the slightest movement of each of them. The information is analyzed by the stabilizer processor, which maintain the stabilized system or to reduce vibrations and undesired movements.
In a programmed manual way, with the physical controls we can perform independent or complementary rotation movements that we physically have been doing, and that is the amazing creative possibilities.
What to look for when buying a smartphone video stabilizer?
Go for a very similar appearance, there are some parts that we have to have very present and value before launching a stabilizer for our smartphone. i.e.
Size and weight of the smartphone:
The majority of stabilizers can easily be adapted to different sizes of mobiles, so make sure that the maximum dimensions are diagonal. As this is a considerable inversion, it would be better to choose a model that we can use both with a smartphone and with a compact or even action camera.
In the technical and figures section, the boundary angles of each type of stabilized movement must be observed: panoramic, inclination and roll. These angles can refer to the robotically controllable range or simply to the mechanical and movement section which is capable of stabilizing. They may be indicated at full angles or at the working edge. It is also important to recognize the maximum movement speed (at angle per second) that allows for a stabilizer.
Relying on the integrated controls on the stabilizer will allow the smartphone, once turned on, to fire or even zoom in, if it can be controlled without touching the phone. Also here we will have the joystick that will allow robotic movements in the best models.
Some models with the main joystick can be configured and included with the remote control for movement once placed on a tripod.
It can be disassembled and transported comfortably and compactly also the construction material which has a transport sling, the material for covering the handle.
Calibration: An important step in the use of the stabilizer is the calibration of the device change. The majority of stabilizers list to use nothing but put the smartphone, with self-calibration, the software aid.
Stabilization does not mean that we always want to keep the smartphone close. Maintaining natural movements and vibrations, working modes allow us more creativity.
The usual way that the gimbal has less vertical and horizontal mode, it is following mode, in which case the camera will follow the movement of our hand and will correct the turns. There are also models that add specific ways to invert the camera and take shallow plans for convenience, or to plan 360 degrees simply by touching a button.
Like any other electronic device, a gimbal needs power so that it can operate the motor and the different electronic systems. There will have to pay attention to the autonomy that offers each model.
The usual will be to find stabilizers with integrated and directly rechargeable battery, and in the best models we can also add docks for situations where it is not possible to recharge the battery (which is removable and interchangeable).
