Actually, I think LosslessCut is pretty good. It’s a video editing tool that lets you trim video without losing quality.

How to trim video without losing quality

Step 1: Download the portable version of the software; it runs directly without installation.

Step 3: Locate the desired start frame, press the shortcut key I, or click the { button to mark the start of the clip.

Step 4: Locate the desired end frame, press the shortcut key O, or click the } button to mark the end of the clip.

Step 5: Click the Export button on the interface, or use the shortcut Ctrl + E to open the export settings.

Finally, specify the save path and confirm; the edited video file will then be generated.

The software can quickly perform lossless splitting without compromising image quality, making it the top choice for users who frequently need to edit raw camera footage, recorded videos, and short videos without losing quality. The entire editing process takes only about one minute to complete.

Pros

• Open-source software
• Zero re-encoding during export; processing is extremely fast, even with large 4K video files
• Shortcut keys for marking start and end points greatly improve operational efficiency
• Supports mainstream video formats such as MP4, MOV, MKV, and WebM

Cons

• Supports only simple cutting and clip extraction; lacks advanced editing features such as filters, text overlays, or color grading
• When the “Preserve video quality without loss” mode is enabled, you cannot modify the video resolution, frame rate, or bitrate
• Occasional parsing failures may occur when processing encrypted or corrupted video files
• No built-in preview zoom tool, so precise frame-by-frame adjustments are not possible
