Example
Example: two minutes out of a 25-minute recording of a team call, at three sizes
team-call.mp4 is a 25-minute screen recording of a video call: 1920 × 1080 at 30 fps, the picture at about 600 kbit/s and AAC sound at 128 kbit/s, 136 MB in all — under the free 150 MB. The demo a client should see runs from 14:32 to 16:47 on the player’s clock.
- Times go in as seconds: 14:32 is 14 × 60 + 32 = 872, and 16:47 is 1007. Start at 872, End at 1007: a 135-second clip.
- Only that part is decoded, from the keyframe just before 872 s, and encoded again, so the job takes about as long as 2¼ minutes of video, not 25.
- Keep the original encodes at the source’s own 600 kbit/s. A smaller size lowers the rate with the pixel count: 720p gets 600 × (1280 × 720) ÷ (1920 × 1080) ≈ 267 kbit/s.
- The AAC sound is copied across untouched, so the voices stay in step with the slides.
| Resolution | Picture | Video bitrate | 135 s clip, about |
|---|---|---|---|
| Keep the original | 1920 × 1080 | 600 kbit/s | 12.3 MB |
| Up to 1080p (1920 px) | 1920 × 1080 | 600 kbit/s | 12.3 MB |
| Up to 720p (1280 px) | 1280 × 720 | 267 kbit/s | 6.7 MB |
| Up to 480p (854 px) | 854 × 480 | 120 kbit/s, the lowest it goes | 4.2 MB |
team-call-cut.mp4, 2 minutes 15 seconds that start on the demo: about 12.3 MB at the original size, 6.7 MB at 720p. Up to 1080p changes nothing here, because the recording is already 1920 px wide. For a second piece, run it again with the next start and end.
How it works
- Drop an MP4, M4V or MOV. One video at a time.
- Type the second the clip should start at, and the second it should end at. Leaving the end at 0 keeps everything to the end of the video, which is what you want when you are only cutting an intro off.
- Leave the resolution on Keep the original unless the cut also needs to be smaller — lowering it here saves a second pass through Compress video.
- Press Trim video. Only the part you asked for is decoded and encoded, so cutting ten seconds out of an hour takes about as long as ten seconds of video, not an hour of it.
- Download the MP4, named after the original with -cut added.
Frequently asked questions
- Does cutting lose quality?
- The cut is re-encoded, at the bitrate the source was recorded at, so the difference is close to invisible — but it is not a byte-for-byte copy. That is not a shortcut we skipped: a video decoder can only start at a keyframe, and keyframes sit a second or two apart, so a cut that lands exactly on the second you typed has to be encoded again. The alternative every “lossless” cutter takes is to move your cut to the nearest keyframe, which is not where you pointed.
- How do I find the right second?
- Open the video in any player, read the time where you want the cut and turn it into seconds: minutes × 60 plus the seconds, so 14:32 is 872 and 1:02:15 is 3600 + 120 + 15 = 3735. Tenths are taken too: 12.5 is halfway through the thirteenth second. If you are unsure, take a second more at each end — a slightly long clip is easy to cut again, a short one is not.
- Which files does it take?
- MP4, M4V and MOV, which covers phone recordings, screen recordings and most cameras. WebM and AVI are not read, because the part that takes the file apart understands MP4 only. Whether the video inside can be decoded is down to your browser: H.264 works everywhere, HEVC works in Safari and in Chrome on hardware that supports it.
- What happens to the sound?
- An AAC track — what a phone or camera records — is copied across sample by sample, never re-encoded, so it loses nothing and stays in step with the picture. A MOV carrying uncompressed PCM, which some camcorders and DSLRs write, cannot be copied that way; rather than drop it silently the tool says so and asks you to choose Remove the sound.
- Can I cut several pieces out of one video?
- Run it once per piece: set the first start and end, download, then change the numbers and run again. Joining the pieces back together is not something this does.
- Which browsers can do this?
- Chrome and Edge, Safari 16.4 and newer, Firefox 130 and newer. An older browser is told plainly when you press the button rather than failing at the end.
- Is my video uploaded, and what are the free limits?
- No. It is read, cut and written in your browser, by the same encoder your phone records with, and nothing is sent to a server, which is the point when the clip is family footage or something recorded at work. The free plan takes one video a run at 150 MB, and 5 runs a day; Pro removes both, and nothing is watermarked either way.
