SRT format: how to create it manually

Unlike other code languages, the SRT format is one of the simplest available. You just need to put the essential information for displaying subtitles: sequence number, time code, text. When you have typed the good structure, your subtitles will automatically display on your player. It’s as simple as that!

Here is a sample SRT file to understand how to build it :

Just repeat this process for the entire length of your video and audio.

However, you may have already noticed it, it is a rather long and complex job to do manually (especially the audio/text synchronization). Fortunately, there are other tools or software to help you with this task.

Which SRT file editor to use?

Since people have started to make subtitles, many subtitling software have been invented to reduce the difficulty of this work (yes, even professional subtitlers admit it, it’s a tedious job).

These SRT file editors have a graphical interface to manage the transcription, but provide also a spectrograph to sync your subtitles accurately. Here is a list of the must-have and free software that can save you time:

Jubler

A classic of open-source subtitling, Jubler provides a comprehensive interface to sync subtitles. You can also transcribe your text at the same time as you run your video, and it includes good customization possibilities. On the other hand, it has an old design, and it is not really updated anymore.

Aegisub

For sure Aegisub is the subtitle software with the most advanced features. It displays the sound spectrum of your video for perfect synchronization, generates a format customizable in detail, and is supported by all operating systems. However, it may seem a bit complex for beginners.

Subtitle-Edit

Subtitle-Edit has a user-friendly and intuitive interface and supports a very large number of different video and transcription formats. It provides also an error correction system, and display audio spectrum. But the interface can sometimes seem complex, and it doesn’t have any customization features.

We let you try them out, and find the tool of your choice according to your needs and skills. But we have even more powerful and faster tools to get the job done. Let us introduce them to you.
