How to create captions yourself

Article sections
Do I create the subtitles myself or order a service?
With HAMK’s supported tools, you can caption your videos either manually or automatically. The subscriber of the video is responsible for the subtitles of the video and their accuracy. You can also buy captioning as a service from Lingsoft
If you want to learn more about the legal basis of video captions, see the article Act on the provision of digital services promotes the accessibility of the videos and audio files
Use auto-captions when:
- typos in captions are allowed
- you have time to check the captions and correct the necessary parts
- you need usable captions for your video quickly
- the sound quality of the video is good
Use manual captions when:
- the video is short
- you have the speech of the video as a transcribed text file
- the video includes special vocabulary and acronyms
- the sound quality is weak
Order captions/subtitles as a service when:
- there are no human resources or time to do captioning
- high quality and accessible captions are needed for the publication channel
- translated subtitles are needed for the speech in the video
- special captions are needed for the speech in the video (captions for the hearing impaired)
