As a module of the audio and video terminal SDK, the short video SDK is used to produce short videos in applications. The short video SDK provides features such as video recording, cropping, merging, subtitles, effects, and same-style cropping. This topic describes the core advantages and features of the short video SDK.
Core advantages
Low-threshold fast accessProvides a product-level SDK and demo source code that includes a user interface (UI) of Standard Edition. You can integrate the SDK with your local services within a minimum of 2 hours. This helps you add short video features to your applications with ease. For information about the demo, see Demo.
Rich and extensible production capabilitiesProvides rich production capabilities such as resumable transfer, filters, subtitles, animated images, and music. It also supports extended features such as efficient retouching effects that are provided by Queen SDK or FaceUnity SDK and face stickers. It also allows you to crop videos that have the same style as an existing video. These features help reduce the difficulty of video production and improve the delicacy of the produced video.
One-stop audio and video servicesProvides one-stop processing of media asset upload, storage, transcoding, review, and distribution based on Intelligent Media Services (IMS). This helps improve your resource management efficiency and reduce maintenance costs.
