Open Video Editor
Open Video Editor 是一款专注于隐私保护的实用工具，专为本地视频转码、编辑和优化而设计。通过在用户设备上直接执行所有操作，该应用确保敏感媒体文件绝不会传输到外部服务器。
该软件利用基于浏览器的技术进行高性能媒体处理。它使用 WebAssembly 在沙盒环境中运行编译后的二进制文件，将密集的解码和编码任务卸载到后台线程，以保持界面的响应速度。该应用通过流式管道处理媒体，以数据块的形式处理数据，从而在保持低内存占用的同时高效处理大文件。
该工具提供了一系列修改视频内容的功能，包括片段修剪、分辨率调整、帧缩放和方向校正。它还支持视觉美化调整，例如为视频添加灰度滤镜。所有文件交互均通过直接访问本地存储进行，确保数据在整个编辑过程中保持安全。
Features
- FFmpeg Transcoders - Provides a local video processing tool that performs editing tasks using FFmpeg without cloud uploads.
- Local Media Processing - Executes all editing tasks directly on the user device to ensure data privacy.
- WebAssembly - Executes high-performance video manipulation code in the browser using compiled binaries in a sandboxed environment.
- Privacy-Focused Media Processors - Executes all video editing tasks directly on the user device to ensure data remains secure.
- Content Trimming - Removes unwanted sections from the start or end of video files to isolate specific clips.
- Media Streaming Pipelines - Handles large media files by processing data in small chunks to maintain a low memory footprint.
- Native File System Access - Reads and writes media files directly from local storage using browser APIs to ensure data privacy.
- Video Quality Adjustments - Modifies pixel dimensions of video files to balance output quality against file size.
- Clip Trimming - Removes unwanted segments from the beginning or end of video files to shorten duration.
- Video Frame Rotators - Changes the rotation angle of video files to correct alignment or achieve specific visual perspectives.
- Frame-By-Frame Stream Processing - Processes video data by decoding individual frames into raw pixel buffers for transformation.
- Video Frame Rescalers - Adjusts resolution and scales frame dimensions to ensure compatibility with display requirements.
- Local File Video Players - Performs video editing tasks directly on local hardware to keep sensitive media files private.
- Video Frame Transformers - Resizes visual content within video frames to match specific aspect ratios or display requirements.
- Video Orientation Controls - Rotates video files to fix alignment issues or adjust the perspective for better viewing.
- Media Transcoders - Modifies video resolution and frame dimensions to optimize file sizes and playback compatibility.
- Off-Main-Thread Processing - Offloads intensive encoding and decoding tasks to background threads to maintain interface responsiveness.
