Why do my Instagram transcript timestamps differ in TXT and SRT?

Use TXT to find a sentence and SRT to place a subtitle. In our paired export, TXT shows the second in which a line starts. SRT keeps the start and end down to milliseconds. A difference between those labels alone does not mean the captions are out of sync.

What changed in our ten-cue export?

We lined up entries by their order in the two files. Entry two was marked 00:00:05 in TXT, but ran from 00:00:05,440 to 00:00:07,360 in SRT. Setting the subtitle to five seconds by hand would start it 440 milliseconds earlier than the exported cue.

Entry nine ended at 38.720 seconds. Entry ten began at 39.360 seconds. That leaves a 640-millisecond gap between cues. The TXT labels, 33 and 39 seconds, tell you neither when cue nine ends nor whether the captions touch. These are measurements of the files; they do not establish when a speaker actually began talking.

How can I check my own file?

Pick one distinctive phrase, find it in both exports, and compare its start marks. Then play the clip just before the SRT start. If the subtitle appears on time, keep the cue. If the words and the audio disagree, adjust against playback. Do not shift the whole track just because the text file displays fewer digits.
