Split hours-long videos right on your phone
Online splitters choke on long videos: uploading an hour of 4K takes longer than the splitting, free tiers cap file size, and your recording sits on someone's server.
Split Video Into Parts processes everything on-device, so file length stops being scary — users have split 7-hour recordings in about 10–15 minutes, and an hour-long video takes seconds to map.
What long-file performance looks like
Real numbers, not lab claims.
| 1-hour video | Cuts mapped in seconds, export in full quality |
|---|---|
| 7-hour video | About 10–15 minutes total — from an App Store review |
| Upload time | Zero — nothing leaves the device |
| Length limit | None. File size is limited only by your storage |
Long videos are the app's home turf: lectures, streams, sports sessions, dashcam and CCTV exports, event recordings.
How to split an hour-long (or longer) video
Import the recording
Straight from Photos or iCloud Drive — no compressing or pre-trimming first.
Choose your split
Equal parts for chapters, a time interval for uniform segments, or manual cuts for highlights.
Let it run
Processing is local and hands-off. The project autosaves, so you can leave and come back.
Export in batches
Save all parts, or re-export just one later — timings persist in the project.
Why on-device wins for big files
No upload tax
A 20 GB recording never crosses the network. The bottleneck online tools hit first simply is not there.
Projects autosave
Split half a stream today and finish tomorrow — cut points are exactly where you left them.
Private by design
Lectures, meetings and family events are processed locally and never touch a server.
“Easily splits an hour video within seconds. 7 hour video took about 10–15 minutes, which is excellent.”
Frequently asked
How long can the video be?
There is no hard limit. A 7-hour video is the longest confirmed by a reviewer — it processed in about 10–15 minutes on-device.
Will a long video overheat or drain my iPhone?
Processing uses the media engine efficiently, but for multi-hour files it is sensible to plug in — the same as exporting from any video app.
Why not use a free online splitter?
Uploading an hour of footage takes longer than the split itself, most free tiers cap file size well below long recordings, and your video ends up on a third-party server.
Can I split a 2-hour lecture into chapters?
Yes — split by number for even chapters, or manually place cuts at topic changes using timecodes from your notes.
What happens if I get interrupted?
The project autosaves. Reopen the app and your video, cut points and settings are exactly where you left them.
