How to change defaultSegmentDuration?

[tarhasov]

When specifying the start of a new fragment, the fragment's end is automatically set at 10 seconds. How can I change this number to, say, 30 seconds, so that the end is automatically set at 30 seconds after the start?

I tried using neural networks to solve my problem, but it didn't work. That's why I'm asking here. Sorry, and thanks in advance for your answer.

There is no setting for it. The 10 seconds is hardcoded, and it only applies in simple mode: when you add a segment there, the end is set to start + 10 (addSegment in src/renderer/src/hooks/useSegments.tsx).

Two ways around it:

• Switch to the advanced view ("Toggle advanced view" in the bottom bar). New segments then start without a fixed end, so you set the end yourself wherever you want it.
• If you want equal 30-second pieces, use Segments → Create fixed duration segments and enter 00:00:30. It splits the file (or the current segment) into 30-second segments in one go.

Thank you very much for your reply. I'm very glad that the new version includes the "Automatically Add Fragment End" feature, but I'm quite disappointed that there's no way to change this number from 10 to any other number.

I don't need identical 30-second fragments. I trim hours-long TV broadcasts and cut dozens of fragments from them, and the fragments always end up in different places for each video.

The "Automatically Add Fragment End" feature DOUBLES my productivity. I'm delighted that it's finally available in my LosslessCut program. At the same time, I'm disappointed that the allotted time for a fragment is so short—only 10 seconds. It would be great if future versions of the program included the ability to manually set the "Fragment Duration" so I wouldn't have to set the end of a fragment each time. This would almost double my productivity.

That makes sense for broadcasts. With segments of different lengths, a fixed default wouldn't fit most of them anyway. What usually speeds this up is using the keyboard for both ends: I sets the segment start at the playhead and O sets the end (both can be remapped under Keyboard shortcuts). Play or scrub to where the fragment should end, press O, move on, press I for the next one. That works in the advanced view too, where no 10-second end is added.

If you still want the 10 seconds to be configurable, it's worth opening a feature request issue and linking this discussion. It's a single hardcoded value in addSegment, so it should be a small change if the maintainer agrees.
