SRT (SubRipe File Format) and VTT (Web Video Text Tracks) are the most popular subtitle file formats for video content. These files include the text of the subtitles in sequence, along with the start and end time codes.

With Accelevents, you can add an SRT or VTT file to complement your recorded video in a session.

Your SRT or VTT file can only be uploaded to Main Stage and Regular Sessions using these stream providers:

If you're uploading the caption file to show during the session, upload your video file first, then the option to upload captions will appear. You can preview the video recording to check if your captions work.

If the live session has already ended and you want to include captions when attendees watch on demand, you can upload the file when the session ends. Go to the Recording tab and click the recording. In the pop-up, you'll be able to upload the file. You can preview the video recording to check if your captions work.

Get it from your web captioner. If you have a live session and you added a 3rd party live captioner, they can provide you with the SRT or VTT file once the session ends. Click here to learn more about adding live captions to your sessions.

Create your own. If you already have your recorded video and want to add subtitles, you can create your subtitle file through numerous sites. You can either type the captions manually or have them generated for you. Here are some site examples:

Your SRT or VTT file can still be edited, even if you didn't create it. You can use the tools mentioned in the first part of this article. If you're editing the file given to you based on a live session, you need to download the recording and upload it to the SRT or VTT editor. Having that video on that platform will be more convenient, so you can play and stop the video while adjusting the caption start and end.

In the example below, we are using VTT Creator where we uploaded the video on the left side and the VTT file on the right side. The line "Howdy! My name is Ariane from Accelevents!" will show up on the screen exactly when the video starts. But if Ariane does not start talking until the 10-second mark after the video starts, then we will need to adjust the start time of that caption to 00:00:10:000 so that the line will show exactly when she starts talking. After adjusting the timings, the file can be downloaded by clicking the save icon. It will only download the VTT file and will not include the video.
