Aegisub - Main Subtitle Editing Features on Mac

Aegisub provides users with standard subtitle editing and customization options. Users can edit their subtitles' font, size, color, and outline. Additionally, Aegisub allows you to manipulate your subtitles, changing their position, rotating them, or presenting them in 3D.

You can adjust the timestamps in the waveform audio preview to place subtitle lines in different video segments. Additionally, you can view the video and audio while editing to ensure precision when subbing.

Who Is Aegisub For?

Admittedly, Aegisub is only suitable for some users.

Initially, Aegisub assisted users wishing to sub anime series that had inaccurate or no subtitles. The idea of the project was to make editing subtitles more accessible and convenient.

Although it may have been an optimal solution at the time, many other solutions are now just as accessible and more convenient. Even considering the thorough instructions and guides to using Aegisub on its official website, the subtitle editor is anything but user-friendly and will likely only suit advanced users dedicated to their craft.

It is a solid tool for subtitle editing, but there are better choices for anyone who wants to capture or generate subtitles quickly and easily.

What Other Mac Users Say About Aegisub

Before deciding whether Aegisub is worth installing, let's see what Mac users have to say.

CNET gave Aegisub a 5-star rating, while Top4Download gave it a 3.4 star-rating.

Although 33 users have given votes and ratings, almost none voiced their opinions. Among the few available reviews was a comment on potential compatibility issues.

I love Aegisub on my Mac. However, it was so peaceful to work on with Mojave. But as my late 2014 Mac mini started acting funny, I downgraded to Sierra. Now, my system seems to be fast and fine, however Aegisub 3.2.2 is acting funny, where I'm not able to make changes to the created subtitles. - gokulthedreamer

An anonymous user on CNET seemed very satisfied.

Perfect assistant. Easy to use, wide variety of functions: synchronization thanks to both audio and video, translation, karaoke modes, style manager and others. It is the best subtitle program I've ever seen. Simple and easy! - Anonymous

It appears that Aegisub users did not have much to report. Considering the lack of user comments, we can only assume that there aren't too many Mac users editing subtitles with Aegisub.
