Cutting Video Duration by Time Range
This video duration cutter extracts a segment from your video by specifying start and end times. Use the sliders or enter exact timestamps to define the portion you want to keep. The tool processes everything in your browser.
The interface shows your video's total duration and lets you set both start and end points independently. The cut portion is extracted and re-encoded as a new MP4 file.
Real-World Applications
- Meeting recorders who recorded a long meeting but only need the presentation portion. They cut out the before and after discussion.
- Content creators who have a 2-hour recording they want to split into multiple shorter videos. They cut it into segments.
- TV recorders removing commercials from recorded TV who cut out the ad breaks, keeping only the show content.
- Teachers who have a full lecture recording but want to share just one topic. They extract the relevant segment.
- Highlight reel creators who cut the best moments from a longer video before compiling them.
What to Know Before Using It
- Timestamps are in seconds, with 0.1-second precision. For frame-accurate cuts, you'd need professional editing software.
- The cut portion is re-encoded, which takes time proportional to the output length, not the original length.
- Very short cuts (under 1 second) might not encode properly due to video codec requirements for minimum frame counts.
- The output is MP4/H.264 format. If your source is a different format, it gets converted during processing.
- This tool makes one cut at a time. For multiple segments, you'd need to process the file repeatedly or use editing software.
FAQ
- How precise are the cuts?
- Approximately 0.1 seconds (100 milliseconds). For frame-accurate cuts, use video editing software.
- Can I cut multiple segments?
- Not in one operation. Download the first cut, then upload the original again for the next segment.
- Does cutting reduce quality?
- The cut portion is re-encoded, which introduces minor quality loss. At reasonable bitrates, the difference is minimal.
- What happens to audio?
- Audio is cut along with video and re-encoded together. The audio stays synchronized with the video.
- Can I preview the cut before processing?
- No—this is a process-and-download tool. For preview, use video editing software with timeline scrubbing.
- Will the cut be seamless?
- The cut is clean, but re-encoding might introduce slight quality variations at the cut points compared to the original.
