Avidemux is an open-source video editor that requires downloading. It offers a practical desktop solution how to crop the length of a video; however, its trimming tool can only adjust frame dimensions rather than the timeline length, and the lossless copy mode will not work properly if the codecs are incompatible.

When supported, it allows you to crop video frames without re-encoding, but the software does not offer a real-time preview feature, so you cannot immediately see the cropping results.

• First, download and install the software from the official website.
• Go to File → Open, then select the target video file.
• Set both video output and audio output to Copy to ensure lossless processing.
• Click Filter → Crop, then enter the pixel values for the top, bottom, left, and right edges.
• Click OK to confirm the settings.
• Go to File → Save → Save Video to export the edited video file.
• Once the export is complete, play the video to verify that the cropping parameters meet your expectations.

This method does not guarantee lossless cropping for all videos; therefore, if you are researching methods how to crop the length of a video, please note that this method only works for files with compatible internal audio and video codecs.

If you prefer not to install resource-intensive editing software, you can try this method. Since there is no real-time preview feature, it is recommended that you first test the cropping parameters on a short clip.

For users who only need simple video adjustments, the built-in Windows Photos app provides a quick way to crop videos without installing additional software. It is suitable for basic edits such as removing unwanted areas from the frame and making small changes before sharing. This method is useful for anyone searching for how to crop a video using tools already available on Windows.

Open the video file with the Photos app, then select Edit and choose the Trim or Crop option depending on the required adjustment. Use the on-screen controls to resize the video area, adjust the visible frame, and preview the result. After finishing the changes, click Save a copy to create the edited video while keeping the original file unchanged.

Because it is included with Windows and requires no extra installation, this method is convenient for quick edits. However, the available tools are limited compared with professional video editors, and some export settings may reduce quality. For simple tasks, it provides an easy solution for how to crop a video directly on Windows 11.

When you learn how to crop the length of a video with OpenCV, the process involves two main steps: calculating the duration and then selectively writing frames to a new file.

First, you need to get the video's properties. OpenCV can read the total number of frames and the frames per second (fps) to calculate the video's duration.

python

import cv2

cap = cv2.Video Capture("your_ video. mp4")

frames = int(cap. get(cv2. CAP PROP FRAME_COUNT))

fps = cap. get(cv2.CAP_PROP_FPS)

duration = frames / fps # Duration in seconds

print(f"Duration: {duration} seconds")

The technique for how to crop the length of a video is to skip frames. For example, to create a video that is half the length, you can write only every other frame to the output file . The cap. grab() method reads and discards a frame, advancing the video position.

python

# ... (code to get video properties and set up VideoWriter)

# To create a video half the length, write every other frame

while True:

ret, frame = cap. read()

if not ret:

break

cap. grab() # Skip the next frame

out.write (frame) # Write the current frame

While it's possible, using OpenCV alone for trimming has significant drawbacks.

• Re-encoding is Required: OpenCV can't perform lossless trimming. It must decode and re-encode every frame it writes out . This means the output video will have quality loss and the process is much slower than using a tool like ff mpeg.
• Complexity: For a simple "cut from 1:00 to 2:00," you must write code to calculate the starting frame index and then loop to read and write only the frames within that range . This is much more involved than using a dedicated tool.
• Frame Accuracy: When you use OpenCV to crop the length of a video, your cut points are limited by the video's frame rate. You can only cut at specific frame numbers, not at exact, arbitrary timestamps like 1:23.45 .

If you're using a Mac, Filmforge is a completely free. The process of using Filmforge to learn how to crop a video is quite straightforward because it provides a visual preview and precision controls.

1. Launch the App: Open Filmforge on your Mac.
2. Open Your Video: Import the video file you want to edit.
3. Find the Crop Tool: Look in the list of its 25+ tools for the "crop with precision" option.
4. Set the Crop Area: A cropping frame will appear over your video. You can drag its handles to select exactly the area you want to keep. This is a key point for learning how to crop a video with exact control.
5. Preview and Export: Before you finalize the crop, you can preview the result in real-time. Once you're satisfied, export the cropped video.

Why Filmforge is Good for This

• Precision Cropping: The app is described as allowing you to "crop with precision," ensuring you can get the exact frame you want.
• Non-Destructive Editing: One of its key features is non-destructive editing. This means you can stack multiple operations and see the combined result live before exporting, without permanently altering your original file.
• Free and No Hidden Catch: The developer explicitly states "Free forever. No catch." and there are no watermarks or daily limits.
• Hardware Accelerated: It uses Apple's native frameworks to run very fast, especially on Apple Silicon Macs, so exporting a cropped video won't take forever.

The app requires macOS 26.4 or later, which means it's designed for the newest versions of the operating system. You'll need to check if your Mac is up-to-date to install and use it. Unlike some other video editors, this is not a web app in a wrapper; it's a purely native application.

In Shotcut, the way to change a video's length is to trim or cut it on the timeline. "Cropping" in video editing usually refers to changing the visible frame area, not the duration . To learn how to crop the length of a video in Shotcut, you should focus on its timeline editing tools, which are slightly different from the "Crop: Rectangle" filter used for frame cropping.

Method 1: Trimming by Dragging

This is the most direct way to adjust the start or end point of a clip to learn how to crop the length of a video.

• To shorten a clip: Hover your mouse over the very beginning or end of a clip on the timeline until the cursor changes to a trim icon (a bracket with an arrow). Click and drag the edge inward to shorten the clip. A pop-up bubble will show you the new duration .
• To lengthen a clip: This is trickier. You can drag the edge outward, but you need enough empty space on the timeline. If there's another clip right next to it, dragging will overwrite it or create a transition. You can also use the Ripple mode (the icon that looks like ripples in water), which will push following clips down the timeline to make room when you lengthen a clip.

Method 2: Splitting and Deleting

This is a reliable method, especially for removing a section from the middle.

1. Move the playhead to the point where you want to make a cut.
2. Right-click on the playhead and select Split (or press the S key) .
3. This will divide your clip into two separate parts.
4. Select the part you want to remove and press the Delete key. You can then drag the remaining clips together.

Keyboard Shortcuts for Precision

For more accurate trimming, Shotcut offers specific keyboard shortcuts:

• Place the playhead where you want the clip to start and press I to set an "In" point, or where you want it to end and press O for an "Out" point. This can help with precision trimming.
• The Shift+I and Shift+O shortcuts allow you to trim the clip under the playhead to the playhead's position, effectively "cropping" its length in one action.

In summary, mastering how to crop the length of a video in Shotcut means becoming familiar with its timeline trimming and splitting functions, rather than its image-cropping filters. The official Shotcut forums and tutorials are excellent resources for learning these techniques in detail.

LosslessCut is a powerful, free tool if you need to learn how to crop a video quickly and without quality loss.

Lossless & Fast: It works by directly copying the video data without re-encoding, which means it's incredibly fast and preserves the original quality perfectly.

Core Function: Its main purpose is for lossless trimming and cutting of large video files. It's perfect for quickly extracting the good parts from a long recording and discarding gigabytes of unwanted data.

How to Crop a video: The basic workflow for how to cut a video with LosslessCut is straightforward:

1. Open your video file.

2. Use the timeline and playback controls (or the I and O keys) to mark the start and end of the segment you want to keep.

3. Click the export button to save the new, trimmed video.

Additional Features: It also supports losslessly merging files, extracting audio tracks, and taking snapshots.

It is important to be aware of how to cut a video precisely with LosslessCut: cuts are not always frame-perfect. The start and end points are often "rounded" to the nearest previous keyframe, which can be a fraction of a second or even several seconds away from your selected point. This makes it a tool for "rough-cutting" rather than frame-accurate editing.
