Free Online Video Splitter
Use the video splitter to divide a recording into short MP4 files at regular intervals. Choose a segment length in seconds and download the numbered parts.
How to use the video splitter
- Open the recording you want to divide.
- Choose the segment length in seconds. The last part can be shorter.
- Download the numbered files separately and play them in order.
How a 67-second recording is divided
- 15 s
- 5 files (four 15-second parts and a 7-second ending)
- 30 s
- 3 files (two 30-second parts and a 7-second ending)
- 60 s
- 2 files (one 60-second part and a 7-second ending)
Each bar covers the same 67 seconds. With the 30-second setting, the third download starts about one minute into the source. A short final part is expected. Actual cut times follow frame boundaries, so use the saved file’s duration if an upload service enforces a strict limit.
Pick a length for each segment
This video splitter divides a single recording at regular intervals measured from its beginning. Choose 5, 10, 15, 30, 60 or 120 seconds. A shorter interval gives you more files to download and more opportunities to send an individual section. A longer interval keeps more of a conversation or demonstration together. The setting applies to the whole recording, including any black frames or silence that occur before the action starts.
A rough file count is useful before you begin. Divide the total recording time in seconds by the selected interval. If a remainder is left over, allow one additional file for it. For a two-minute recording split into thirty-second parts, expect four parts. For two minutes and seven seconds, expect a fifth part containing the final seven seconds. Actual boundaries follow video frames and can differ slightly from the displayed times.
If a service accepts clips up to a certain duration, open a downloaded part and check the duration reported by that service or its editor. Some players round their time display to whole seconds. When you have room to choose a shorter interval, leaving a margin can avoid a rejection at an exact cutoff.
Decide whether you need regular parts or a specific excerpt
Use the video splitter when the important requirement is a regular length, such as a sequence of short uploads from a longer recording. The divisions do not follow changes of speaker, chapters, quiet passages or scene cuts. If a sentence begins just before the next interval, its ending will be in the following file. Keep adjacent parts together when a viewer needs to hear that entire exchange.
To take only a particular passage, locate its beginning and end in the source and use the trimming tool. If you need regular segments starting at a particular moment, first trim the source to start there, save the result and then open that copy in the video splitter. The first interval will now begin at the new opening frame. This is useful when a short countdown at the beginning would otherwise shift every subsequent cut.
For several excerpts with different lengths, set their in and out points individually in a timeline editor. Dividing a long file into equal pieces and repeatedly removing material from every piece can create more work and can leave small gaps between sections you meant to keep.
How the video splitter numbers the downloads
The video splitter exports separate MP4 files. The results take their names from the source filename and include a numbered part suffix. For a source called lesson.mp4, the first two downloads are lesson-part-00000.mp4 and lesson-part-00001.mp4. Keep those suffixes when moving the downloads to a new folder. Sorting by filename then restores the playback order even if the files finished downloading at different times.
Each part starts its own playback clock near zero. A subtitle file timed to the complete recording will therefore need new timings to match a later part. For example, a line appearing at one minute and seven seconds in a source split into thirty-second parts belongs about seven seconds into the third part. Check the actual first frame of that download before adjusting every subtitle by a fixed offset.
The segments are re-encoded so that they can be opened separately. Expect differences in byte size even if several parts have the same duration. A moving crowd or a fast camera pan can take more data to encode than a stationary title card. When the receiving service also sets a limit in megabytes, check the size of each saved part.
Listen and watch across the cut
Start with a numbered file from the middle of the list. Open it directly, seek towards its end, then open the next file. Check that both begin with a readable picture and that the change from one to the other occurs at the expected moment. Pay special attention to a split through a fast movement, a sung word or a spoken instruction that continues across the boundary.
The last part often has a different duration from the others. Compare its final picture and sound with the end of the source before treating a short final file as a failed export. If the source itself ends early, opening it in the video splitter cannot recover the missing material. If the source plays in full, confirm that you saved the last numbered result and did not simply stop at the preceding file.
Video splitter questions
Does the video splitter remove the time between the parts?
The selected interval sets the spacing between cuts. The segments cover the source in order. For a gap you deliberately want to discard, trim out that passage in an editor and split the resulting recording.
Can I download just the part I need?
Yes. After processing, each part has its own download link. Use the interval and part number to locate the passage, then open the saved file to verify the start and end before sharing it.
Can the video splitter divide a file into equal megabytes?
The setting uses seconds. Equal durations can produce very different file sizes. Pick an interval that suits the content, then compress any part that exceeds the receiving service’s actual byte limit.
