How Do We Add Captions to Twitter Video Upload
A Quick Guide To Creating Captions For Twitter Videos
About a year and a half ago, Twitter announced that airtight captions could exist added to Twitter videos. It was a big win for accessibility advocates, besides as those of united states of america in public radio who want curt spoken-discussion files to play inside of Twitter.
Since there'south no native audio player in Twitter, they have to be displayed equally video, oft with a single, static epitome. And since volume is turned off by default, captions really help users appoint with this audio.
Now, the process of adding captions is relatively elementary. Unfortunately, at that place are some serious gotchas involved. Fortunately, I am here to guide you lot through them.
Upload Your Video
This is the easiest step. Get to the Twitter Media Studio. Though be warned: Not every Twitter account has access to Media Studio. (According to this page: "Currently, admission to Media Studio is given on an invite-only footing. If you do not have access to Media Studio, please accomplish out to your account director.")
Then click the Upload Media button in the upper right-mitt corner. Follow the directions. But be certain that it is no longer than ii:20! That is a hard limit for Twitter. (Though according to this page: "Certain advertisers may authorize for whitelisting for longer video uploads.")
Create A Transcript
You now need a text file of the actual words to your audio/video, and in the proper format (SubRip, aka .srt). Youcould create one past hand, but you'll quickly detect that to be painstaking and unrewarding — especially since there are already a number of automated oral communication-to-text services that are relatively inexpensive, lightning-fast and surprisingly accurate.
Trint, for instance, is very popular in newsrooms, and it allows you to export the results equally an .srt file. We use Amazon Transcribe, considering it's already integrated with other AWS tools like s3 and AWS CLI. On the downside, the stop results come out in a proprietary Amazon format. So yous'll need an extra tool to plow Amazon Transcribe JSON into an .srt file.
Double-Bank check Your SubRip File
SubRip files are uncomplicated, intuitive, human being-readable text files. Yous can open up them in whatever text editor. And they look something like this:
one
00:00:00,000 --> 00:00:02,410
I'm meteorologist Dave Epstein, with the Greater Boston area
2
00:00:02,410 --> 00:00:05,310
forecast information technology's Tuesday, September 1.
3
00:00:05,680 --> 00:00:08,250
Wow, Hither we are, September 1st, the beginning of
That being said, Twitter can reject your file with a less-than-helpful message of: "There was a problem uploading your subtitle (.srt) file." So it's important, at to the lowest degree when you first outset, to review and troubleshoot your .srt file, to save yourself hassle downwards the road.
- Are the captions in the proper order?
- Are there any devious characters in the file?
- Well-nigh important, each fraction of a second should be represented by three digits, even if your original file format but went to i or two places. Twitter volition reject your file without those 3 digits, and so pad your times out with zeros, even if, technically, they are not needed. And make certain y'all utilize a comma, rather than a decimal point.
If yous're looking for a more than specialized tool, I recommend trying out Aegisub, which is billed as "a free, cross-platform open source tool for creating and modifying subtitles."
Understand The Terminology
Here'southward the bones breakup:
- Closed captions provide an on-screen transcription of the video's dialogue, for when the sound is off, or for the hearing impaired.
- Open captions are very similar to airtight captions, just they tin't exist toggled on and off. They are actually office of the video, or "burned in."
- Subtitles provide an on-screen transcription when the dialogue is not understood by the viewer. Think artsy French movies. Thinktranslation.
Unfortunately, Twitter insists on referring to its airtight captions equally "subtitles," and is fairly unapologetic virtually it: "Subtitles, equally we're defining them, are transcripts of a video's dialogue or sound contained in .SRT files that are attached to videos." It's not a federal crime, just it does muddy the waters. And then retrieve, when you're Googling for help about Twitter closed captions, try: "Twitter subtitles."
Upload Your .srt File
Now y'all can upload your .srt file. Though, that might not exist entirely intuitive. Click on the file name. Y'all want the Subtitles tab of the "Media details" modal window.
Tweet And Test
Now you can just tweet out the video. All the same, you might not immediately run across the captions. First, for unknown reasons,captions don't appear in the desktop web version of Twitter, if you are logged in. (They testify up fine on mobile.) So while on a desktop, y'all'll either need to log out of Twitter or open the tweet in an incognito window. Second, make sure that you lot have toggled on the closed caption [CC] button in the video.
One terminal note, if y'all observe any mistakes in the captions, fret not. Yous can edit your .srt file and re-upload it, fifty-fifty if you lot've already tweeted out the video.
