How can I crop a mp4 video and cut a part of it in Windows?

Currently, I work with an MP4 video that needs two things done to it — first, cropping the frame to remove unwanted edges and black bars around the footage, and second, cutting out a specific section...

If you are looking for an intuitive and open-source desktop solution for basic video editing, OpenShot is a fantastic choice. Featuring timeline controls and frame-by-frame precision, it combines clip splitting and visual trimming into a single, beginner-friendly application. As a practical, all-in-one tool, it stands out as the best mp4 cropper for handling everyday post-production tasks smoothly.

How to Use a Best MP4 Cropper

  1. Download and install the software from the official website.
  2. Launch the software and import the source video file into the project library.
  3. Drag and drop the imported video clip onto the main timeline track.
  4. Trim the video: Right-click the video clip, select Properties, and then adjust the trim values to remove excess edges or black borders.
  5. Trim the video: Activate the Scissors tool, click the point on the timeline where you want to split the video, and then delete the unwanted segment
  6. Once editing is complete, click the Export button, select the MP4 preset, configure the output parameters, and start rendering

Drawbacks

  • All export operations require the video to be re-encoded, which inevitably results in a slight loss of video quality.
  • Rendering is relatively slow when processing long, high-resolution videos.
  • Occasional preview stuttering may occur when working with multiple overlapping video tracks.

Serving as an intuitive solution for beginners, this open-source tool combines visual cropping with timeline editing, making it ideal for creators who need quick video adjustments while carefully managing export settings to minimize quality loss.

ps

  • Save your project file frequently before exporting to prevent losing your editing progress in case of a program crash.
  • Close other resource-intensive background applications to prevent insufficient memory during video rendering.
  • If you only need simple, lossless cropping, a lightweight lossless tool will be more efficient.
  • Preview the cropping results repeatedly before rendering to avoid incorrect frame range settings.
