You've added a caption file to your video. At certain times, you see that the captions go from the bottom of the video to the top of the video.
This might occur at random time frames within the video due to some unseen formatting characters within the caption file.
- Navigate to the Captions tab on the video
- Select Download and download the caption file back in ".SRT" format
- After downloading the file, delete the current caption file that is applied to the video.
- Re-upload the file that you just downloaded. Test your captions again.
If the problem persists, please contact Vidyard support for further assistance.
