Frequently asked questions

What is a video trimmer?

A video trimmer shortens a clip by removing footage from the start, the end, or both. Most trimmers have you drag two handles on a timeline. With Manus, you can also describe the part you want to keep.

How do I trim a video with Manus?

Attach the video in a chat and say which part to keep, either with times like 0:05 to 0:20 or by describing the moment. Manus trims it and gives you the new file to download.

What is the difference between trimming and cutting a video?

Trimming removes footage from the beginning or end of a clip. Cutting removes sections from the middle. Manus can do both in one request, for example “remove the first 5 seconds and the pause at 0:42.”

Can Manus find the part to keep for me?

Yes. Describe the moment instead of giving times, like “the part where she shows the finished dish.” Manus can transcribe speech and check frames to find it. Watch the result before you post it. If you also need the words, the video transcript generator turns the recording into text you can edit.

What is the best desktop video trimmer?

It depends on how you like to work. If you only drag handles, most desktop editors do that well. If you also want to describe the cut or ask for changes, Video Editor in the Manus desktop app lets you do both on the same project, on Mac and Windows.

Can I trim a video on Windows?

Yes. Trim it online in your browser, or install the desktop app for Windows to trim on the Video Editor timeline.

Can I trim a video for TikTok, Reels, or YouTube Shorts?

Yes. Say the length you need and ask for a 9:16 version in the same message. Manus trims and crops the clip in one task.

Does trimming a video lower its quality?

It does not have to. A trim without re-encoding keeps the original quality, but the cut lands on the nearest keyframe, so it can be off by a moment. For an exact cut the clip is re-encoded, so ask Manus for a high quality setting if that matters to you.

Which video formats can I trim?

You can attach MP4, MOV, MKV, WebM, AVI, WMV, FLV, M4V, 3GP, MPG, and MPEG files. Tell Manus which format you want back, such as MP4 or the same format as the original.

Can I trim a video that Manus made?

Yes. A video from the AI video generator opens as a full project in Video Editor, so you can trim each shot on the timeline or ask Manus to shorten it.
