I have short chunks of narration with long pauses. PP is generating accurate closed captions BUT the captions stay on the screen throughout the silences, until the next chunk of narration comes along. They should disappear after the viewer has read them.
There is a minimum length setting but not a maximum length setting.
Short,of manually trimming every caption, is there a way to fix this problem?
I don't know whether precise timing of when speech ends is a feature to be expected. But the results I just got in the Beta are odd. So I won't comment on whether you can get any closer to your goal in PR at the moment. I suspect that you cannot. In any event, I understand the issue you are seeing, and, for now, we're looking for a workaround.
I hope you're on PC, because the tool I like best for this, Subtitle Edit, is PC only.
Export the captions as srt. Open in Subtitle Edit. First set your preferences: Options -> Settings -> General. I think you will only need to set "Max. duration, milliseconds." The default is, I think, 5 seconds (5000). There are also settings for such things as "Max. chars/sec" - so play as you wish and let us know what you find.
Then use Tools -> "Fix common errors." Select at least "Fix long display times." It will show you what it proposes to fix, and you can select which fixes to apply.
Save as srt. In PR, disable the original caption track. Then "Import captions from file." You can only see one track's captions in the display, but you can compare what has changed by the segment lengths in the timeline.
Thanks. I'm on a Mac but I will take note of that PC solution.
I think the expected behaviour from Premiere Pro should be to leave subtitles on the screen from the cued moment for a maximum of n seconds, ideally user-configurable the way the minimum is, but probably 5-7 is about right. At the moment it leaves them up for ages and ages and this just looks dumb.
There's a bug of some sort. I'll report in on the Beta version, since that is where it will be fixed.
My test 54 minute sequence is composed on 16 instances of the same clip, and background noise may account for part of the issue. But in that sequence, I had 6 occurences of extremely long caption segments, as in 28 to 32 seconds in duration.
The Beta version is experimenting with detecting certain types of errors, but it did not detect these.
Thanks, do please report it. Actually I think it is both a bug (because this is a dumb way to set the end of captions) and a missing feature (because the user should have control over the maximum duration).
This picture illustrates the problem quite nicely I think. The bottom line is the narration, and the captions along the top line are generated from that. You can see that some of the captions are absurdly long.
Here is one such caption:
Clearly no one would take 34 seconds to read nine words.
