Subler: Embed titles and edit metadata in QuickTime movies
Subler is a free software for Mac that allows you to easily edit metadata in video files and add subtitles to QuickTime movies. With Subler, you can mux video, audio, chapters, subtitles, and closed captions tracks from MOV and MP4 files. It also supports creating tx3g subtitles tracks compatible with iPod, AppleTV, iPhone, and QuickTime.
One of the standout features of Subler is its simplicity. It does not have a traditional user interface. Instead, it only opens when you open a video file. Once opened, you can clearly see and edit the audio language, attached metadata, video format, and duration. However, it should be noted that Subler can be prone to instability, especially when working with MP4 files.
While Subler is a useful tool for editing metadata and adding subtitles to QuickTime movies, it does have some limitations. The interface is limited in functionality, and it does not support DivX files, despite MP4 being a container for the format.
Overall, Subler is a handy application for those who need to edit metadata or add subtitles to QuickTime movies, although it may not be perfect.
