The image of the captured videos will possibly be jittery or the horizontal of the photo will be incorrect. Please refer to the tutorial to perform Gyro calibration.(Note: Gyro calibration will only affect the newly shot videos. The App or Studio cannot be used to adjust the already captured videos. So it is recommended to use third-party software to adjust: Premiere Pro 2019 or Final Cut Pro X 10.4 has its own direction adjustment plug-in for this purpose. Photoshop 2019 or higher can help with photos.)
