I just ran across a new YouTube feature that’s pretty amazing if you think of the technology behind it. You can upload a video and a text file that is a transcript of the video, and YouTube will process both and link them so the text displays along with the video when played. Here’s an example I uploaded:
I think you have to click on the caption button after the video starts.
It doesn’t make a caption crawl like on TV, but displays the text below the video window and bolds the part that matches in real time.
You can upload a “caption” file with time tags, or a simple text file, and Youtube figures out where the text matches the speech in the video.
My text caption file was not a perfect transcript, but slightly edited to remove speech stutters and junk, but it didn’t cause any problems. Neither did the speaker’s names that preceded some lines.
One oddity, at least in my trial, is that most “the” words got translated to “xe” or sometimes “the xe”.
The next step would be for YouTube to create a text transcript from the video alone. Now that would be great for government meetings, so you could search for key words, find the text, then find the related video. I’m sure that will come in time.
