How to Cut a Video

Most videos need cutting before they are worth sending: the rambling intro, the dead air in the middle, the bit at the end where everyone is already packing up. The usual editors handle that by re-encoding the whole video — slow, and every re-encode shaves a little quality off. There is a cheaper way to do the same job, and it is the whole point of this tool: copy the video and audio streams bit for bit, rewrite only the container, and be done in seconds with picture quality mathematically identical to the original.

Here is the exact flow in the free Video Cutter. You pick what to keep by dragging blocks on a timeline — what you drag is what you get — and everything outside those blocks is dropped. One trade-off to know before you start: lossless cuts can only land on keyframes, so your cut point gets rounded to the nearest one, usually within 1 to 3 seconds. For trimming intros, outros, ads, and dead air, that is more than precise enough.

What You Need Before You Start

Get these ready first, so you are not stopping halfway to hunt for a file:

One video file — MP4, MOV, or WebM, under 500 MB. That is what the tool's dropzone lists, so if your clip is something else, convert it first.
A rough sense of the parts worth keeping — not exact timestamps, just "the middle story" or "everything after the intro." You will place them by eye on the timeline, so a vague plan is enough.
Room for a second pass — because cuts snap to keyframes within 1 to 3 seconds, do not plan a cut that must land on an exact frame. If frame accuracy matters more than speed and quality, this is the wrong tool for that job, and the page says so itself.
A browser tab you can leave alone for a moment — the first run loads the video engine (about 30 MB, one time), so the first cut pauses briefly before it starts.

One thing that trips people up: this tool keeps what you select and drops everything else. It does not work like a pair of scissors that removes one piece — you draw blocks around the good parts, and the gaps between them disappear. Keep that mental model and the multi-segment steps below will feel obvious.

How to Cut a Video, Step by Step

Step 1: Add your video

Open the Video Cutter and drop your video onto the dropzone, or click it to pick a file from your device. Already copied it? Ctrl+V pastes it straight in. Once it loads, the video appears in a preview player with a timeline underneath — that timeline is where all the real work happens. Play the video through once if you have not already, so you know roughly where the good parts sit before you start dragging.

↗ Got a clip with a slow intro to lose? Open Video Cutter in a new tab and drop it in — the timeline underneath the preview is where this guide picks up.

**Figure 1.** The tool after a video is loaded. Arrow 1 points to the preview player; arrow 2 points to the timeline underneath it; arrow 3 points to the dropzone's format list (MP4, MOV, WebM) and 500 MB limit. This figure matches Step 1.

Step 2: Drag a block around the part you want to keep

This is the core move, and it is all dragging — no typing timestamps to get started. On the timeline you will see a colored block: drag its edges to resize it, and drag the block itself to move it along the timeline. The block is the part that survives; everything outside it is dropped. Stretch the block to cover the segment you want, then click the block to preview just that segment and check it starts and ends where you meant. If the edges feel slightly off, nudge them again — the preview shows you exactly what the block contains, so trust your eyes over your memory of the timestamps.

↗ This one only makes sense with your hands on it — open Video Cutter in a new tab, load a video, and drag the block's edges until the preview shows the part you want.

**Figure 2.** One segment selected on the timeline. Arrow 1 points to the colored block; arrow 2 points to its left edge handle being dragged; arrow 3 points to its right edge handle. This figure matches Step 2.

Step 3: Fine-tune the edges, if you want to

Dragging gets you close; the tuner underneath the timeline gets you closer. When a block is selected, its start and end show as numbers in seconds, and you can adjust those numbers to nudge an edge that your finger or mouse could not quite land. Think of it as fine adjustment after dragging, not a replacement for it — drag first to find the segment, then type only if an edge needs a small correction. And remember the keyframe rule while you do this: the final cut still snaps to the nearest keyframe, usually within 1 to 3 seconds, so chasing sub-second precision in the numbers will not change the result.

↗ Edges almost right but not quite? Open Video Cutter in a new tab, select the block, and nudge its start and end numbers after you have dragged it into place.

**Figure 3.** Fine-tuning a selected segment. Arrow 1 points to the start number box; arrow 2 points to the end number box; arrow 3 points to the selected block on the timeline that these numbers describe. This figure matches Step 3.

Step 4: Add more segments, or cut out a middle section

One block is rarely the whole story. Click + Add segment to keep another part — you can have up to 20 segments, and the kept parts are joined into one video automatically, in timeline order. Changed your mind about a block? Select it and click Delete. The trick for removing a middle section falls out of the same logic: add two blocks, one covering everything before the unwanted part and one covering everything after it. The gap between them — the part you do not want — is simply dropped when the blocks are joined. No separate "remove" mode to learn; keeping two blocks is removing the middle.

↗ Got a boring stretch in the middle to lose? Open Video Cutter in a new tab, add a block before it and a block after it, and watch the gap disappear in the result.

**Figure 4.** Two segments with a gap between them. Arrow 1 points to the + Add segment button; arrow 2 points to the first block; arrow 3 points to the second block; arrow 4 points to the gap that will be dropped. This figure matches Step 4.

Step 5: Cut and download

When your blocks cover everything you want to keep, click Cut Video. Because nothing is re-encoded, even a 500 MB file finishes in seconds — the streams are copied bit for bit and only the container is rewritten. The first run is the exception: the video engine (about 30 MB) loads once, so the first cut pauses briefly. When it is done, click Download and save the result as an MP4. Then play it through once: check the joins between segments feel natural, and check the start and end of each kept part, remembering that each cut may sit up to a couple of seconds from where you dragged it, thanks to the keyframe snapping.

↗ Blocks in place? Open Video Cutter in a new tab, hit Cut Video, and play the downloaded MP4 once before you send it anywhere.

**Figure 5.** The finished state. Arrow 1 points to the Cut Video button; arrow 2 points to the Download link that appears once cutting is done. This figure matches Step 5.

Why Is My Cut Point Off by a Second or Two?

That is the keyframe rule, and it is the price of zero quality loss. Lossless cutting can only start and end on keyframes — the full reference frames in the video stream — so your cut point is rounded to the nearest one, usually within 1 to 3 seconds. The tool's page is upfront about this, and it frames the trade honestly: for trimming intros, outros, ads, or dead air, keyframe precision is more than enough, and it buys you instant speed with identical quality. If you ever need a cut on an exact frame, that requires re-encoding, which this tool deliberately avoids. Knowing which kind of job you have before you start saves the one frustration this tool can actually cause.

Common Problems and Fixes

File refused on upload? The limit is 500 MB, and the listed formats are MP4, MOV, and WebM. Check both before retrying.
Cut point off by a second or two? Expected. Lossless cuts snap to the nearest keyframe, within 1 to 3 seconds. Drag the block a little wider if the snap cut into something you wanted.
Result missing a part? Only the blocks survive. If a section is gone, it was outside every block — add a block covering it and cut again.
Middle section still there? You probably kept one block spanning the whole video. Split it into two blocks with a gap over the unwanted part, and the gap drops out.
Nothing happens on the first click? The video engine (about 30 MB) is loading for the first time. Wait it out — later cuts start right away.
Quality looks different? It should not — streams are copied without re-encoding, so quality is identical to the source. If something looks off, compare against the original at the same timestamp; the cut, not the quality, is usually what changed.
Too many segments? The cap is 20. If you are past it, merge nearby blocks into wider ones and let the small gaps go.

That is the whole job: add the video, drag blocks around the good parts, add more blocks or a gap where you need them, cut, download. The mental shift that makes it click is the keep-model — you are not deleting bad parts, you are selecting good ones, and everything unselected quietly disappears. Once that lands, trimming a video stops being an editing project and becomes a thirty-second task, with the original quality intact at the end of it.
