Overview

WM Splitter is a really easy way to extract or remove portions of audio and video files. With a visual display, and an easy way to include and exclude segments of your media, you'll be slicing and dicing video and audio files in minutes.

WM Splitter supports these popular video and audio formats:

If your media is not in one of these formats, use a conversion tool like WM Converter.

Here's a quick summary of the editing process:

1. Load your media file.
2. Add Markers to split your media into Segments.
3. Include or exclude segments.
4. Output the resulting file.

Hint: Position the mouse arrow over any button to read what the button does.

How to Edit Media

Here are the basic steps for editing audio and video files:

1. You'll need to load a file to edit first. Click the Input button, then pick a file from the dialog:
   
   
   
   
2. Pick a file to edit, and click Open. The file is loaded and your display looks something like this:
   
   
   
   
3. Next, you'll need to mark segments. Click on the timeline where you want to mark a segment boundary, then click the Add Marker button . A new marker appears as shown:
   
   
   
   
4. You now have two segments. To include a segment in the final output file, click it to select, then click the Include button . The segment appears bold.
5. To exclude a segment, select it, then click the Exclude button . Below shows a file with two segments, the first one included, and the second one excluded:
   
   
   
   
6. Once you're done marking segments, click the Output button, and enter a file name for the output file. The newly edited file is built.

Hints:

• WM Splitter makes it easy to navigate to important parts of the file. See the How to Navigate Media section for details.
• You can get a size estimate for the final file by clicking the Size button.
• To invert your selections (change included segments to excluded, and vice versa), click the Inv (invert) button.
• You can delete markers easily: Just click the marker, then click the Delete Marker button .
• Use the Zoom In and Zoom Out buttons to magnify the timeline.

How to Navigate Media

Now that you know how to do basic editing, it's time to learn how to move the selector to important parts of the audio or video file. WM Splitter has a lot of really handy ways to get to the important parts of any media file. Here's everything you need to know about navigating:

• Use the Play button to play the video or audio from the selection point. You can set a marker at the current playback position at any time using the Add Marker button .
• The Navigation menu lets you move forward and back in various handy increments, and also gives you a quick reference to the various keyboard shortcuts:
  
  

About K-Frames

The left and right arrows move to the previous or next K-Frame. K-Frames are significant points of transition in a video file - usually the start of a new scene or camera shot. Moving between K-Frames is an efficient way to locate important segments quickly.

Here's the technical side of K-Frames. Video files are a series of images. When video files are compressed, rather than compressing each image in the video, some images are calculated as a difference from the previous image. If there are several seconds with little movement, for example, rather than saving each frame of the same image, the video compressor just saves the differences between each frame, which may be small. This leads to efficient compression. However, there are times when two adjacent frames are very different, such as a new camera shot. In that situation, an entirely new starting frame - the K-Frame - is brought into the compression process. Ensuing frames are again calculated as differences from the K-Frame.
