Tampere University and TAMK

Videos uploaded to the online service must meet accessibility standards from September 23, 2020. Videos must be made accessible within 14 days after posting them online. The accessibility requirement does not apply to old videos (before 23.9.2020). Read more Accessible videos.

Creating subtitles

When subtitling on the Panopto video platform, Microsoft Stream (Sharepoint) or the Screencast-O-Matic subtitling program, you can use automatic speech recognition to produce subtitles, but these always require a subtitle check. With the Subtitle Edit program, subtitles are created manually by typing without automatic speech recognition. Particularly good features of the Subtitle Edit program are the precise adjustment options for how much and for how long the text is displayed on the screen at a time.

Check the subtitling instructions for Panopto, Microsoft Stream (Sharepoint) and Screencast-O-Matic in the next paragraph, see also the instructions for the Subtitle Edit application.


Adding ASR (Automatic Speech Recognition) captions to Panopto video

You have the ability to add subtitles created by ASR (Automatic Speech Recognition) to Panopto videos. Speech recognition works in Finnish by default, but you can change ASR language to English by changing video folder settings: Folder Settings > Settings > Content language.

You can also change the ASR language of uploaded files: select settings > captions > available captions > change language. Panopto instructions for reprocessing automatic captions:

Note that it is a good idea to check and edit subtitles created on the ASR to ensure their accuracy.

After the transition to the new Panopto environment (4.12.2020), in addition to the text produced by Panopto, you can add subtitles from a file (different language versions).

ASR subtitles are not available in the editor as soon as the video has been downloaded and processed. Below are the target times for auto captions.

Targeted caption completion time for videos with an hour or less: 8 hours
