Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of video acquisition equipment, in particular to a video acquisition conversion equipment for camera live lens operation and a video acquisition card. BACKGROUND

[0002] Camera shooting lens operation is a key element in photography art, which involves camera movement and lens operation, aiming to create a variety of visual effects. Whether it is basic push, pull, shake, shift, follow lens, or advanced techniques such as surround, low angle, lift, and throw lens, it can add unique charm to the work. Pushing the lens is to move the lens from far to close to the subject, so that the picture gradually focuses on the subject. This technique is often used for close-up shots or product demonstrations to highlight the subject and guide the viewer's gaze. On the contrary, pulling the lens is to move the lens from close to far from the subject, showing a wider scene, often used for opening shots or environmental introductions to create a spectacular and spatial effect. Shake lens and shift lens involve rotating the lens horizontally or vertically, and moving the camera horizontally or vertically, respectively. Both techniques can describe space, introduce the environment, and show different sides of the subject. Shake lens is often used to shoot large events or landscapes, while shift lens is suitable for tracking shots or action scenes.

[0003] However, when live streaming is performed, in order to ensure normal lens operation effect, a support is usually used to install the camera on the support, and the camera is moved with the support during lens operation. However, if multiple lens effects are required, multiple supports are needed, which is relatively troublesome to use. SUMMARY
