If frame gap refers to a gap between each subtitle line, why would anyone want this when often people talk in continuous sentences/paragraphs without any pauses in speech?

Also, do the gaps correlate with time periods? E.g., does a two frame gap mean two second gap?

Thank you

Frames are not the same as seconds Nov 10, 2020

You can check the properties of the video to see how many frames are in each second, but there are quite a few. So 2 frames just makes up a tiny bit of each second. A 2 frame gap between subtitles is actually really quick and isn't a problem for continuous speech. A 2 second gap would be a problem. Definitely don't do that.

Gaps are important in the sense that they allow a better reading. Let's say some character talks for a long time, how do you pack it all in one subtitle? The end result would be that half the screen is filled with text. So, long speeches need to be separated into several subtitles.
As Kristohper said, a frame is a short period, a fraction of a second. If this makes sense, imagine that a two-frame break is the equivalent of quickly taking your breath during a speech. It's the same in subtit

It's the same in subtitling, we avoid subtitles that go for too long or are too bloated so that it's comfortable to read, and frame gaps are the tools we use to divide a speech.

Hi, Jenny. It seems to me that you must be new to subtitling. As other colleagues explained, 2 frames are just a very tiny fraction for a second. Just do the maths: in PAL videos there are as many as 25 frames per second. In NTSC there are even more (29.97), so it's just an interval of two frames (imagine two pictures you take with your camera) between subs without which the reading would look too continuous and heavy on the eye.

Hope this is clear to you now.

For your information, frame gaps are just one of the many parameters you need to bear in mind in professional subtitling that have to do with:

- Accurate IN and OUT times, time to audio
– Frame rate management – Smart text condensation
– Speech rhythm compliance – Number of characters per line
– Number of lines per subtitle
– Frame interval between subtitles
– Minimum and maximum exposure
– Reading speed
– Syntax division
– Working around shot and scene changes
– Other individual aspects to consider based on the particular AV content

All of the above put together make sure subtitles are readable within their short exposure times and that's why subtitling should be left to professionals.
