Subtitle Creator

Aegisub is free opensource software for creating subtitles for videos. You can select any video of you choice, load it into Aegisub, and start creating your subtitles. This is great for creating music videos, tutorials, karaoke, and more.

Text Editor

In Aegisub’s text editor you can customize your subtitles to look exactly how you want them. You can select the font type. This allows you to download any font of your choice and implement it into your video. You can change the font to bold, italic, underlined, or strikeout. You can select the margins as left, right, or vert.

Audio Tools

Aegisub has audio tools to help you find where to time your subtitles best. You can highlight the area you want to add you subtitles, type what you want the subtitles to say in the box below and click the green check mark. This applies the subtitles where you have highlighted the audio. The audio meter allows you to see sentence breaks and when to stop and start your subtitles.


Under the video playback Aegisub has an area that shows when, what, and where you subtitles are applied. It gives you the start and end time so can make sure you subtitles are in the correct position. It also tells you how many words are in each scene and if it thinks you have to many words for that section of subtitles.

Cross Platform
