Is the last chunk always the full interval?

No. The last chunk contains whatever's left over. For a 23-minute file split every 5 minutes, you'd get four 5-minute chunks and one 3-minute chunk at the end.

What interval should I use?

Depends on your use case. For podcast clips: 1–2 min. For chunked uploads to platforms with size limits: 5–10 min. For audiobook chapters: match your target chapter length, e.g. 20–30 min. Any duration `MM:SS` or `HH:MM:SS` works.

Can I use seconds instead of minutes?

Yes — enter `0:30` for 30 seconds, or `1:30` for 90 seconds. Any `MM:SS` or `HH:MM:SS` time works as the segment length.
