Adding captions to your videos can be so valuable. It helps those watching without sound to know what the video is about. It will keep those people engaged for a longer time period or even get them to un-mute the video and listen with sound at a later time. But what happens when you are running a Facebook LIVE video? Captions are not there since it is live. So how do I go about adding captions to my videos? Well it’s a pretty simply process and can be done in just a few steps.
Step 1: Download video from your Facebook Page. Pretty easy & simple to do. As long as you are an admin of the page you will have access and be able to do this pretty easily.
Step 2: Upload video to YouTube as Unlisted video & hit save. Unless you want the video showing up on your channel, I upload as unlisted and then add all the proper information before sending the video public on my YouTube Channel.
Step 3: Once video has finished processing on YouTube, go back & edit the video and click on the Subtitles/CC tab. 
Step 4: Click Add New Subtitles or CC and Select desired Language.
Step 5: Choose and auto-sync
Step 6: Type captions in type what’s spoken here box. Make sure the Pause while typing box is checked. Click play on video and transcribe along. When finished, click Set Timings
Step 7: Wait a few moments for YouTube to process new file and then go and manually adjust any timings that need to be adjusted.
Step 8: Go back to edit captions menu and click download .srt file. 
Step 9: Rename SRT file by adding correct extension to end of file. Facebook doesn’t like just SRT files, you need to manually rename file from captions.srt to captions.en_US.srt
Step 10: Go back to Facebook & edit video and go to captions file and upload newly saved file.
Step 11: Click save and your are finished! Captions are now running on your new LIVE video.
