I'm working on some digital preservation projects and often need to make quick edits without the hassle of using complicated, resource-intensive software. My main requirements include: extracting audio from video files, replacing existing audio, adding basic captions or subtitles, and fixing any audio sync issues. I'd love some suggestions for any apps that fit the bill—whether they're open source or not, simple or with a few additional features. Thanks in advance for your help!
