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.
