How To Add Captions & Subtitles To Twitter Videos

Users on Twitter can upload SRT files with their videos directly while composing a tweet.

Keep in mind that Twitter only supports MOV and MP4 video files and that Twitter will not allow you to post more than 2 minutes and 20 seconds of video.

Step 1 – Transcribe Video or Align Transcripts

Log into your 3Play Media account.

From the Upload tab at the top of the screen, select From ComputerFrom LinksFrom Linked Account, or Cloud Storage depending on where your video lives. Choose your video, and follow the onscreen prompts.

How to Add Subtitles to Twitter Videos

If you want to add subtitles for other languages, submit your video for translation after it’s been transcribed.

In your 3Play Media account, click on your video file under My Files.

Select Order > Translation.

Choose the language you want for your subtitles, as well as the style of translation.

Once your translation is completed, go to Translations under My Files, follow instructions from Step 3 to download your subtitle file and post your video to Twitter.

3Play Media enables T-Mobile to meet fast approaching deadlines and deliver high quality closed captions. The support team is very responsive and show that they care about the quality and efficiency of their services. I highly recommend 3Play Media to video publishers looking for professional transcription services with a partner that is easy to do business with.
