Cut Video Online — AI Video Cutter

Type where the cut goes — by timecode, by what was said, or by what happens on screen. The agent does the cutting.

To cut a video online, upload it to Valmera and describe the cut in plain English — "cut 0:12 to 0:47" or "remove the part where I sneeze". The AI agent finds the moment by timecode, transcript, or what's on screen, makes the cut, and shows you a preview. No timeline, no software install.

How to Cut a Video Online

  1. 1
    Upload your video
    Drag in any MP4, MOV, MKV, or WebM up to 2GB or 3 hours. A one-time analysis with visible progress maps the transcript, shots, and silences — that's what lets you describe cuts instead of scrubbing for them.
  2. 2
    Type "cut 0:12 to 0:47"
    Or describe the content instead of the clock: "remove the part where I sneeze", "trim the first 10 seconds", "end it after I say 'thanks for watching'".
  3. 3
    Preview, adjust, export
    Watch the preview, fine-tune in chat — "start the cut half a second later" — then export a full-quality H.264 MP4 rendered from your original file and download it.
HONEST NOTE

The first analysis is the slow part: on long videos it takes a while, and you'll see its progress as it runs. It happens once per upload. After that, editing is conversational — each request renders a fresh preview, and the final export renders from your original file at source quality.

EXAMPLE PROMPTS
  • "cut 0:12 to 0:47"
  • "trim the first 10 seconds"
  • "remove the part where I sneeze"
  • "cut everything after I say 'thanks for watching'"
  • "restore the section you cut at 1:05"

Cut by Timecode, by Words, or by What's on Screen

A timeline gives you one way to address a moment: scrub until you see it. Valmera gives you three. Exact times work when you know them — "cut 0:12 to 0:47". The transcript works when you remember what was said — "cut the tangent about pricing" — because the analysis maps every word to its timing. And the picture works when the moment is visual — the agent looks at real frames from your footage, so "remove the shaky clip near the end" lands on the right shot.

This is text-based video editing taken to its conclusion: the cut is wherever you can describe, in whatever terms you naturally think in.

Trim the Start and End Without Scrubbing

The most common cut on the internet is the simplest: shave the fumbling at the start, drop the dead ending. In Valmera each one is a sentence — "trim the first 10 seconds", "end the video after I say 'thanks for watching'" — and because the agent reads the transcript, trimming by what was said is often more precise than eyeballing a frame.

Cut Out the Middle Without Splitting Clips

In a manual editor, removing a section from the middle means razor at the in-point, razor at the out-point, delete, close the gap, then check you didn't knock anything downstream out of place. Here it's one request — "cut 3:20 to 4:05" or "remove the part where the doorbell rings" — and the join is handled for you. When a cut lands on speech, it snaps to word boundaries from the transcript, so the sentences on either side stay whole.

No Quality Loss — Exports Render from Your Original

Many free online cutters re-compress your video on the way out. Valmera keeps two separate paths: previews render from a lightweight proxy while you iterate, and the final export renders from your original upload at source quality as an H.264 MP4. Exports are downloads — your file, posted wherever you like.

Change Your Mind? Restore Any Cut

Cuts live in the edit, not in your file, so nothing is destructive: "restore the section you cut at 1:05" brings it back at any point, even after further edits. The honesty layer verifies every agent reply against the edits actually made, so when the agent says the cut happened — or didn't — that's server-checked truth, not chat optimism.

Who cuts video this way? People clipping a meeting or lecture recording down to the useful part, creators tightening a take before captions, marketers pulling the sneeze out of an otherwise perfect demo — anyone who needs scissors, not a film school.

More Than a Video Cutter

Cutting is usually step one. The same chat can remove every silence, cut the ums and uhs, drop repeated takes, and change speed from 0.25x to 4x with voices keeping natural pitch — then caption, score, and reframe the result. Browse the full AI video editing tools hub or read the cuts & cleanup docs for the mechanics.

It's free to start: 20 credits every day plus a one-time 150-credit welcome bonus, no credit card. You're charged for the work actually done — simple cuts cost the least. See plans and pricing if you edit a lot.

Frequently Asked Questions

Upload the video to Valmera in your browser — nothing to install — and describe the cut in plain English: "cut 0:12 to 0:47", "trim the first 10 seconds", "remove the part where I sneeze". The AI agent makes the cut and renders a preview; when it looks right, you export and download the finished MP4.
Yes. Describe it by time ("cut 3:20 to 4:05") or by content ("remove the tangent about pricing"), and the agent removes that section and joins what remains. When a cut lands on speech, it snaps to word boundaries so sentences on either side stay whole.
One sentence each: "trim the first 10 seconds" or "end the video after I say 'thanks for watching'". Because the agent has a word-level transcript, you can trim by what was said instead of hunting for the exact frame.
Not on Valmera. Previews render from a lightweight proxy while you iterate, but the final export is rendered from your original upload at source quality as an H.264 MP4. Your original file itself is never modified.
Free, yes — fully watermark-free, only on Plus and Pro. Valmera's free plan includes 20 credits every day (they reset daily and don't accumulate) plus a one-time 150-credit welcome bonus, no credit card required. On Free, a small Valmera mark sits in the corner of your export; on Plus and Pro there is no watermark at all. Every export closes with a brief (~2.5-second) Valmera end card after your video.
It depends on the video's length — the analysis transcribes every word and maps shots and silences, and on long videos that takes a while. Progress is visible the whole time, and it only happens once per upload. After that, cutting is conversational: each request renders a fresh preview.
MP4, MOV, MKV, and WebM, up to 2GB or 3 hours per upload. Everything runs in desktop and mobile browsers — there's no app to download, and exports are files you download and post anywhere.
