Introduction to the Kuaiying APP

Kuaiying is a mobile AI video editing application developed by Beijing Kuaishou Technology Co., Ltd., aimed at short-video creators, account managers, and users who want to keep daily records. It combines AI-powered script and asset generation, digital avatars, intelligent scene segmentation, automatic subtitles, and professional timeline editing, allowing users to create content quickly while also enabling them to make detailed adjustments to visuals, audio, and text.

Main functions of the Kuaiying app

• AI-generated copy for videos:Thanks to the built-in AI, it is possible to write, rewrite, and refine video scripts, and to convert these scripts directly into videos; this makes it ideal for the quick creation of videos for voiceovers, knowledge sharing, and marketing content.
• AI video animations:After uploading a video of a person, an animated effect is generated automatically, converting the real-person movements into a virtual avatar style; this provides new forms for short films, profile pictures, and creative expressions.
• AI image generation:Enter a description of the image and select a style for it, and the corresponding image will be generated; this can be used to create video illustrations, covers, backgrounds, or any other visual elements that are missing.
• AI art generation:Upload the initial image and select the desired style; the system will generate a new rendering. You can also add keyword descriptions to further shape the visual outcome.
• AI digital humans:Select the appropriate character from the digital avatar lineup, assign voiceover scripts and presentation methods, and quickly create videos for explanations, product promotions, or news reports.
• Intelligent storyboarding:It analyzes changes in the video footage and automatically splits the video into multiple separate segments, enabling users to accurately identify the points where cuts occur, so as to adjust or reorganize those segments individually.
• Creation Center:It provides topic ideas and creative inspiration for account management, helps in understanding the direction of the content and audience preferences, and reduces the difficulty of continuously planning themes for short videos.
• Basic video editing:It supports functions such as splitting, cropping, stitching, reversing, as well as setting cover pages and end credits; users can organize the materials on the timeline to create a complete video structure.
• Transitioning and keyframes:It offers regular, curved, and custom speed controls, and allows keyframes to be used to manage changes in image properties, thereby creating speed gradients and smoother dynamic effects.
• Smart voice dubbing:Convert text content into speech to quickly add narration to videos of a narrative, dramatic, or educational nature, thereby reducing the workload associated with separate recording and post-production alignment.
• Automatic captioning for speech:It identifies the audio in a video and generates subtitles; users can then review the content, adjust the font style, and apply various formatting options to make the information clearer and more prominent.
• Audio editing:It supports extracting audio from videos, enabling noise reduction, adding music and sound effects as well as setting musical beats, which facilitates the unified handling of dialogue, background music, and rhythm.
• Image beautification and composition:It offers tools such as filters, beauty effects, video backgrounds, and picture-in-picture functions, which can be used to enhance the appearance of the subject and the background, or to combine multiple elements within the same image.
• Intelligent keying:It automatically identifies faces or subjects and separates the background, allowing users to change the scene, add new backgrounds, or create multi-layered creative compositions without the need for a green screen.
• Templates and popular assets:It offers video templates that cover various creative styles, as well as stickers, filters, special effects, transitions, and popular assets; by replacing the content, it is possible to create similar works quickly.
