You can make your videos more accessible to your users by adding subtitles for as many languages as you would like. To add subtitles, you will need a VTT file. If your format is different, you can convert it, simply do a Google search for VTT convert.
If you want to create the captions in VTT or auto-generate them, you can check out VEED, a video editing platform that allows you to add captions/subtitles, transcription, and translation to your videos.
Navigate to Content, go to Videos, select the video you want to add subtitles to, and click Edit. Then scroll down and click Upload Subtitles. Select the subtitle file, and Save the changes.
If you need to know how to create subtitles in the VTT format, try a free service like VTT Creator.
Troubleshooting your Subtitles
After you add subtitles, if you notice the timing of the subtitles is slightly off, please make sure your timestamps in the file are correct.
Since our videos are playing per NTSC, this means our videos play in Drop Frame. Please make sure your source video file is in the Drop Frame and not in Non-drop Frame to ensure the best alignment of your subtitles with your film.
