视频字幕

Closed captions are required for all videos posted to Lenoir-Rhyne University websites and social media sites managed by university faculty, 教职员及学生.

All websites funded by the university, including LR social media websites, must comply with federal accessibility requirements and include closed captions. This applies to all department or program social media accounts, 包括Facebook, 推特, Instagram, YouTube, Vimeo and any site where videos are posted.

For social media sites like Instagram that don't offer the ability to upload a separate caption file, we recommend adding captions as an overlay on the video file using freely available tools like the VideoLan VLC播放器 (Mac、Windows或Linux)或 MacX视频转换器专业 (Mac). Be sure to make a copy of the original video file first and add your video captions directly to the video copy (again this is only for sites that don't offer the option to upload a separate caption file like an .srt文件).

Recommended Free Captioning Workflow

Some application services like Zoom offer free captioning. If the application or service you use does not offer captioning, we recommend that you use YouTube for captioning videos. YouTube offers automatic captioning and creates a caption file that can then be edited through the YouTube account interface. A final version of the edited captions can be exported for use on other websites, 包括Facebook, 推特和Vimeo, or captions added as an overlay to videos posted to Instagram.

  1. Create a department YouTube account - use the naming convention Lenoir-Rhyne [Department Name]. 如果需要的话 provide other users with access to the YouTube account you can do so in the YouTube account interface. 另请参阅 how to create a YouTube account.
  2. 上传 video to YouTube as an 未上市的视频 - this allows the video to not appear publicly on YouTube channels or YouTube search, but have it available for automatic captioning. Allow one-to-two hours or more for automatic captions to run (longer videos may require more time). You do not need to submit a request for automatic captions to start, it happens automatically. Once video captions are edited and finalized you can change the video from unlisted to public so it appears in your YouTube channel and in YouTube search
  3. 编辑自动字幕- once automatic captions are run, the captions file will appear in your YouTube captions screen. You can edit the captions file directly within the YouTube interface. 另请参阅 how to review, edit and publish automatic captions.
  4. 下载 .SRT标题文件 - download a final version of the edited captions file (.SRT文件) for uploading to other sites that use captions, 包括Facebook and Vimeo. An .SRT file is a text file that includes captioned text with time codes that correspond to the content in your video. 使用 .SRT file to apply a captions overlay to videos uploaded to 推特 or Instagram. 另请参阅 如何下载 .来自YouTube的SRT文件.

*Important note about the accuracy of YouTube automatic captions: YouTube automatic captions are only 60-70 percent accurate and typically lack proper capitalization and punctuation, may miss some words or include words that are clearly incorrect. Simply relying on automatic captions alone, 没有任何编辑, is not in compliance with federal website accessibility requirements.

分享 .SRT标题文件

.SRT files can be uploaded/shared with other sites, 包括YouTube, Facebook and Vimeo or added as text overlays on a video file before uploading to sites that don't yet support captioning like 推特 and Instagram.

  4. Display captions directly on video file (Instagram) - some websites don't yet support uploading a separate .SRT标题文件. For social media sites like Instagram that don't offer the ability to upload a separate caption file, we recommend adding captions as an overlay on the video file using freely available tools like the VideoLan VLC播放器 (Mac、Windows或Linux)或 MacX视频转换器专业 (Mac). Be sure to make a copy of the original video file first and add your video captions directly to that video (again this is only for sites that don't offer the option to upload a separate caption file like an .SRT文件).

付费字幕服务

There are a large number of paid services that will caption videos. For human-captioned videos, you can expect to pay $1.25 per minute or more for video captioning through a paid service.

There are cheaper alternatives that rely on artificial intelligence (AI), but provided captions may still contain errors and inaccuracies that must be manually corrected to be in compliance. Captions done via AI can range from $.25 per minute from a service called Temi or $8.50-$13 per month for an Otter AI monthly or annual plan. 

Marketing and Communications recommends using 牧师.com if you feel the need to use an outside service for video captioning. Their cost is affordable and turnaround time is typically within 24 hours or less. The end result is a professional caption file that needs little, if any, editing. 牧师.com can also access your YouTube and Vimeo accounts directly and upload the final captioned file for your approval after it is completed.
