NoaLingua Feature
NoaLingua auto-pause, sentence by sentence
The video stops at the real end of every line, and the box holds the line you heard
Press A and the video stops at the end of every sentence. The playhead rewinds to the real sentence boundary before pausing, so it lands where the sentence actually ends rather than where a late translation put it — and the box keeps showing the line you heard rather than racing on to the next.
Fit
Who Auto-pause is for
Choose it for the workflow it actually supports, not for a promise the product does not make.
Best for
- Learners who want unlimited time with a sentence at the speed it was actually spoken.
- People who click words, save sentences or shadow a line before letting the video continue.
Not the right fit for
- Passive watching, where stopping at every sentence turns a film into an exercise nobody asked for.
- Anyone wanting the video to pause only on selected words: the unit here is the sentence throughout.
How to use it
How to use Auto-pause in NoaLingua
- 1
Press A, or the Auto-pause button under the box
The same action is on the key, on the control strip under the subtitles, and in the quick menu under Playback as "Pause after each sentence". The button exists so the key is discoverable; its tooltip shows your current binding.
- 2
Work on the sentence for as long as you want
Both lines stay on screen. Click any word for its meaning in this sentence, press S to keep the whole line as a card, press X to hear it again slowly, or press H to shadow just this one.
- 3
Continue with space, play, or any navigation
The sentence you move into does not immediately pause again, so continuing does not mean stopping a second later. Dragging the scrub bar releases the hold entirely — where you want to be is your decision, not the mode's.
- 4
Press A again to turn it off
It is a mode rather than a one-off action, and it persists until you turn it off. Combined with reveal-on-demand it becomes a test: read the original, guess, press V, find out.
Mechanism
Why NoaLingua behaves this way
Why the playhead rewinds before it pauses
A translation can arrive a second or two after the line it belongs to, and a naive implementation pauses when it notices the sentence has ended — which is late by exactly that amount, somewhere inside the next sentence.
So the playhead is first moved back to the sentence's true boundary, and only then paused. The boundary is known because NoaLingua fetches the whole transcript once per video and drives the box from it, with real per-sentence timings rather than caption-block edges.
Why the box does not race ahead
This was the most-reported problem in the product's history: the video paused, and the subtitle box was already showing the next sentence — so you were looking at a line you had not heard while trying to work on the one you had.
The fix was to make every writer to the box ask the same question first: is anything currently holding the screen? While auto-pause holds a sentence, the next one is queued and appears when you continue. One question, asked in every code path, rather than a special case per feature.
What happens when a translation never arrives
The pause waits up to two and a half seconds for a late translation, and then pauses anyway. A dead translation source must not be able to switch off a feature that has nothing to do with translation.
The related hover-pause setting — stop the video when the mouse enters the subtitle box — follows strict rules for the same reason: a pause you made yourself is never undone by it, and while auto-pause is holding a sentence, hover-pause stays out of the way.
Common questions about NoaLingua
How do I continue?
Space, the play button, or any navigation — previous, next, or clicking a sentence. The sentence you move into will not pause immediately, so continuing gives you a whole line rather than a fraction of one.
Does auto-pause stay on between videos?
Yes. It is a setting rather than a per-video state, so it is on the next time you open a video until you turn it off.
Can I make the video pause on hover instead?
Yes — "Pause while the mouse is on the subtitles" in Settings → General. It is off by default, and it never overrides a pause you made yourself.
Is this the same as shadowing?
No. Shadowing (Ctrl+H) plays the line, stops, counts down a gap for you to repeat it, and continues on its own. Auto-pause stops and waits indefinitely for you.
