Part of the Zerocoder platform
One tool of a platform where AI generates websites, images, video, text and documents — under one subscription.
A social-media moment out of a long clip, a webinar excerpt for colleagues, a screen-recording piece for a ticket — trimming covers the most common video chore. The fragment cuts without re-encoding: the stream is copied as is, quality untouched, processing takes seconds. Heavy result — run it through video compression; a short piece comes alive as a GIF; audio extracts via MP4 to MP3. All tools — in one section.
Re-encode-free cutting: why it's fast
A regular editor recomputes every frame — minutes of work and quality loss. Stream copying just moves the needed byte range into a new file: seconds for any clip, zero loss. One trade-off: cuts align to keyframes, so the start can shift a second or two.
Picking exact seconds
Open the clip in a player, find the moment, note the timecode. Take the start a second early — keyframe alignment. Duration counts from the start: a 1:30–2:00 fragment is start 90, duration 30.
A fragment for socials: what's next
Vertical platforms love short pieces: 15–60 seconds. After trimming, shrink it with compression, make a cover with frame grab and enhance it in the Zerocoder Studio.

FAQ
Does quality degrade?
No: the fragment cuts without re-encoding, the stream is copied as is.
Why did the start shift?
Cuts align to keyframes — up to a couple of seconds. Take the start with margin.
What's the maximum fragment length?
Up to 10 minutes per run.
Which formats are accepted?
MP4, MOV, WebM and other common containers, up to 100 MB.
Is audio kept?
Yes, the audio track is copied along with the video.
Do I need an account?
The first result needs no account. Video operations are heavy, so the signed-in limit is one per day; light tools get 5 a day.
What happens to my files?
Nothing is stored: processing uses temp files deleted right after the response.
How many runs per day?
One video operation per day — they're heavy on the server. Light tools get 5.
What else does Zerocoder do?
AI video, image and text generation, courses, jobs — the video utilities are one part of the Studio.
