Mastershot 推出免费在线视频编辑器 Studio，AI 工具本地运行

Mastershot Studio · free to start

A free online video editor, with no watermark on anything you export.

Trim, combine, and add music, text, and subtitles in one project instead of one tool at a time. Your files open straight from your computer, so there’s nothing to upload first.

How to edit a video online

1. 01

   Add your videos

   Start a project and drop in your videos, photos, and music. They open straight from your computer, so even a 2 GB video is ready right away.

2. 02

   Edit them on the timeline

   Drag clips into order, trim their ends, and split them at the playhead. Text, pictures, and music go on the rows above and below.

3. 03

   Export once

   Pick a size and click Export. You get an MP4 with no watermark, in up to 4K, made on your computer.

Every step, with screenshots, is in Studio’s help.

Trim, combine, add music, and crop in one project, then export once.

Online, a video often takes one site to trim the clips, another to join them, and a third to add music, downloading the video each time and losing a little quality with every save. In Studio those are steps in a single project, and the video is saved once, at the end.

Cut and arrange

• Trim and split clips

  Drag a clip’s ends to trim it, or press S to split it at the playhead.

• Combine videos and photos

  Line clips up in order, or stack them on rows for picture-in-picture.

• Speed, freeze frames, and reverse

  Play a clip at a quarter to four times its speed, hold a frame, or play it backwards.

Text and effects

• Text and titles

  Pick a font and colors, drag it into place, and animate it in and out.

• Transitions

  Crossfade, slide, wipe, zoom, and four more between any two clips.

• Filters and color

  Start from a preset look, then adjust the brightness, contrast, and warmth.

• Pan and zoom

  Move slowly across a photo, or zoom into part of a screen and back out, as many times as a clip needs.

Sound

• Add music

  Put a song on its own row, set its volume, and fade it in and out.

• Record a voiceover

  Talk over your video as it plays, and the recording lands where you spoke.

Size and shape

• Vertical, square, or wide

  Switch to 9:16 for TikTok, Reels, and Shorts, 16:9 for YouTube, or square.

• Crop, rotate, and flip

  Keep the part you want, or turn a sideways phone video the right way up.

All of it is free.

Other online editors put a watermark on free exports, or let you edit and then ask you to pay when you click Export. Studio has no paid plan: the whole editor, 4K exports, and the AI tools are free.

Questions

Yes, all of it. There’s no paid plan: exports in up to 4K, with no watermark, and the automatic features, such as subtitles and background removal, are free.

No. Nothing you export from Studio has a watermark.

No to both. Studio runs in Chrome, Edge, or Safari on a computer, and it opens your files straight from your disk. A 2 GB video is ready to edit right away instead of after a long upload.

No, it’s a new editor. The one we ran from 2021 until September 2026 is retired, and Studio replaces it. Like the old one, it works in your browser.

They stay free, with no limits and no watermark. If you only need one quick job, like compressing or converting a video, they’re still the fastest way to do it.

Yes. You sign in with Google or with an email and password. Your account keeps your projects, and the video files stay on your computer.

Not yet. Studio needs a computer, with Chrome, Edge, or Safari. On a phone, Mastershot’s other tools still trim, compress, and convert videos.

For one quick job, Mastershot’s free tools are faster.

They don’t need an account, they work on phones too, and nothing you make with them has a watermark.
