Just click on the Captions tab at the top of the video you want to edit. You’ll get the option to upload a file with the captions enclosed. This works best if you’ve recorded the transcript before you recorded the video, but I know some of us don’t roll like that. We record on the fly. I personally use an outline. Click the blue “Upload Caption file or Transcript” button on the right. Then choose the file with your transcript or captions. You’ll most likely have a transcript file, as a caption file will include the time stamps next to the words and that is more time consuming to create. Be sure to toggle the circle for Transcript file if that is what you are using. Give it a track name, so you’ll know which file it is if you need to edit it.
This file should be text only (txt). I haven’t tried a .rtf file yet. YT will process the file and this can take some time if it’s a long video. Be patient, and you may need to refresh the page to see if it is finished. When it’s finished, you’re set.
If you need to edit the file for whatever reason, you can easily do so by clicking on the Active track. You’ll have the one you uploaded, as well as a “automatic captions” track. The automatic captions is the one YT transcribed for you; the one that is not as correct as you wished it would be. In either case, you can edit that one or edit the one you uploaded.
The video will show on the left and these captions on the right. You can watch the video and type in the caption boxes as you go. This is the actual transcripts that YT did for my video. You can see it doesn’t make much sense as is. I have to type in each time stamped box to correct the text. It goes pretty fast once you get the hang of it. In addition, you can download the automatic captions file and edit it. It’s a weird file name (sbv), but it opens in a text editor.
All in all it’s a pretty simple task and worth it for that time when you finally get a hearing impaired student.
