Boo you and your incorrectly formatted captions file, LinkedIn!

Get past the "the captions file you selected is incorrectly formatted" message on LinkedIn.

Brie E Anderson

So, you got the dreaded message… “The captions file you selected is incorrectly formatted LinkedIn.”

Well, we’ve got good news and we’ve got bad news. The good news is only one of five things can be wrong!

The bad news is that it could take FFFOOOORRREEEVVEERR to find which of the five things it is.

Let’s break it down.

5 Things That Could Be Wrong with Your Captions

1. Sequence Numbers

The first thing an SRT file has is a sequence number. You start with sequence 1 then go up front there.

Errors to check for:

  • Do you skip any sequence numbers
  • Do you repeat any sequence numbers

If either of these errors is the issue, be sure to renumber every sequence following the initial incorrect number.

2. In/Out Times

Directly under the sequence number are the in and out times. The formatting is 00:00:00,000 --> 00:00:00,0000. Those zeros stand for hours, minutes, seconds, and milliseconds. Then you use two hyphens and a greater than sign to point to the end time.

Errors to check for:

  • Ensure you have hh:mm:ss,ffff in every in and out time
  • Correct punctuation (two colons, one comma, two hyphens and one greater than sign) in every sequence
  • Make sure your out and in times don’t overlap

3. Caption Text

There needs to be some form of text in each caption section, even if it is simply a space or a hyphen.

Errors to check for:

  • Text in every sequence

4. .SRT file Extension

SRT files should be encoded in UTF-8 text file. When you create a text file, it will automatically save as a TXT file. You will need to change that extension to SRT. If the file already has the SRT file extension but is not encoded UTF-8, you will need to open the file with a text editor and save it under a new name.

Errors to check for:

  • Lacking the SRT extension
  • Not encoded UTF-8


Each portion of the sequence online gets one line. These files are finicky and extra spaces my them illegible.

Errors to check for:

  • Extra spaces between sequences
  • Extra space at the end of the file

Save Your Time (Good news!)

So, the bad news - finding the errors is DIFFICULT.

When you have a video with a lot of words in it, the number of sequences needed is large and the larger the sequence number, the more lines you have to look at.

It could take longer to find the error in the SRT file you’ve created than it did to create it in the first place.

If you don’t want to bother with that, don’t worry, we have a simple solution.

QuiCC generates an independent SRT file from your video while also burning in the captions to your video.

The SRT file makes the video searchable by search engines, but you could skip that part altogether for LinkedIn video and just use your video with the burned-in captions.
