Subtitle files contain more than just text; they also need to include information about when and how long each subtitle must be displayed. Subtitle files should have timestamps, too; these make sure that the correct subtitles are displayed and synchronized with what's happening in the video.
​
Timestamps use the following format: [hours]:[minutes]:[seconds],[milliseconds]. Each subtitle line has two timestamps, a start time and an end time. The start time is listed first, followed by an arrow (—>), and ends with the end time.

Suppose you try to upload a TXT file without timestamps to our subtitle converter. In that case, we'll let you know that we can't automatically convert these to another subtitle format, as it doesn't contain all the required data.
​
​To fix this issue, you'll need to add timestamps to your .TXT file. You can choose to manually add timestamps to your file by editing the .TXT file, or you can upload your video/audio file and generate subtitles automatically.
​
At VEED, you have the option to upload your video/audio file, and you'll be able to add the subtitles automatically. You can also check our article on How to add subtitles to a video automatically, which will walk you through step by step on how to add subtitles to your file.
