Online Video Captioning Tools: 5 Professional Free Tools

Today, subtitles are essential in videos. They allow anyone to view the video without sound and at any time. They also allow accessibility for deaf and hard of hearing people.

However, captioning is not an easy task: you have to transcribe the audio into text and then fit it perfectly on the video. To make your life easier, there are transcription software. Today we present to you 5 tools to allow you to caption like a professional and for free.

1 – Youtube

Youtube has understood it well, subtitles are essential for good visibility on social networks. For this reason, Youtube offers a tool to subtitle its videos. The interface is precise to use.

To subtitle with Youtube, you must first host your video on the platform then go to Creator studio and finally to the video manager. With Youtube, you can either create your subtitles or import a subtitle file, or use automatic subtitles. Automation is however very hit and miss and rather poor.

Advantages :

  • Tool integrated into the publication platform
  • Possibility of adding subtitles to the video in several ways: downloading a file, manual or automatic transcription
  • The Youtube video is in Open Caption, it is possible to add several subtitle tracks to the same video

  • You must also post your video on Youtube to then be able to add the subtitles.
  • Transcription is poor when it is automatic
  • No possibility to style your subtitles
  • Unable to recover video with embedded subtitles

2 – Kapwing

Kapwing is a video editor that offers several services: gif, adding subtitles, resizing videos … Kapwing allows you to easily edit videos by offering you several features. Accessible to all, this software is rather complete to edit an entire video even without editing skills. Subtitles can be added manually or automatically. However, the timeline for timing the subtitles is not very practical and the automation of the subtitles is not optimal.

But above all, we deplore the slowness of this online editor and the export which is long and sometimes contains bugs.

Unlike other solutions which have complicated interfaces, the subtitle editor Captured looks like a Word document, and it’s also easy to use: just click on it to edit its subtitles.

On classic subtitle editors, we often find ourselves in the need to fit a part of a sentence into the following subtitle for lack of space. It is often long and off-putting because you have to copy the text from one box, paste it into the other, while on Capté, you just need to press the Enter key to make the text of a subtitle jump. to the other, as with a simple text editor!

The procedure for adding subtitles:

  1. Go to the Capté application

5 – Subtitle Horse

Subtitle Horse is an online tool that allows you to easily subtitle .flv files or videos hosted on Youtube. But above all: Subtitle Horse is very similar to Premiere Pro! But beware, the tool is not easy to understand at first glance and handling can be difficult. If you are used to Premiere Pro, getting started with the tool will undoubtedly be easy, otherwise you may waste time in this step as well and we therefore recommend another alternative for captioning. The subtitles are written manually as the video unfolds and then all you have to do is place them on your timeline. Also pay attention to a certain specificity: the tool favors large screen dimensions, if your screen is small this may make it impossible to access the tool or harm the user experience.
