For larger files or offline work, you can use built-in tools or dedicated software:

: Open your MP4, go to Edit > Split Clip (or press Command-Y) to break the video into segments. You can then delete the pieces you don't need and save the remaining part.

: Upload your MP4, right-click where you want to cut, and hit "Split." You can then delete parts or shorten the duration before downloading.

: For 4K or very large files, tools like Shutter Encoder or Avidemux can "cut" the piece without re-encoding, which preserves the original quality and is nearly instant. 🛠️ How to Split Your Video Upload : Drag your MP4 into the editor's library.

: A fast option where you can use the "S" key to split clips on the timeline and remove unwanted sections.
