If you just want to trim something off the beginning and the end you can change the start and end times just to show what you want without actually cutting out anything,.
If you mean adding and cutting stuff then you will have to download it into a video editing program (but remember that if you do that you can NOT them upload the edited version to the zoom cloud.
As @AGH3rd mentioned, you can trim the beginning and end off of a cloud recording, but that is just making those portions available for view when watching from the web. If you or a user downloads a copy of that trimmed recording, the entire recording will be provided.
Actual editing of the recording will require downloading the files and editing in video software.
To edit a cloud-recorded video, follow these steps:
Download the video file from the cloud storage to your local device.
Choose a video editing software or app that supports your editing needs.
Import the downloaded video file into the editing software.
Trim and cut unwanted sections, rearrange clips, or add transitions and effects as desired.
Edit audio tracks, adjust volume levels, or add background music.
Include text overlays, titles, or captions if needed.
Enhance the video quality, adjust colors, or apply filters if desired.
Preview and review the edited video to ensure it meets your expectations.
Save the final edited video in a desired format and resolution.
If necessary, upload the edited video back to the cloud storage for sharing or further access.
Remember to check the documentation or tutorials specific to the video editing software you choose for detailed instructions on its features and functions.
