As suggested by the title, suppose I’m given all the video links under a YouTube channel.
Is there anyway that I can tell if each video has close captions automatically generated by YouTube or manually added by users without clicking into each video link and turning on the subtitle to check its quality?
YouTube does not support filtering an specific account's uploads to only show captioned videos.
However you can filter the search result for videos with subtitles like this.
Search something in YouTube
Click FILTER on the top left corner
In the dropdown below, under the FEATURES column, there's Subtitles/CC. Click this.
Now all results below have manually added captions.
