This wizard takes you step by step by dividing / cutting a .MKV video file into two different files.
Note: The steps and screenshots in this guide are specific to Windows. That being said, if you are using macOS or Linux you will have absolutely no problems with it, these versions are almost identical to the Windows version.
- Start by going to the MKVToolNix download page and download the version for your platform. If you are using Windows and are unsure whether to choose the 32 or 64 bit version, check out this short guide to find out the right one.
- Once the download is complete, install the app (unless you have chosen to use the portable version, which does not require any installation). When done, start the program.
- To start, click the New button in the middle of the window.
- Locate Add source files button at the bottom of the window and click it.
- Navigate to the .mkv file you want to share, select it, and then click the Open button.
- Give MKVToolNix a moment to process the file and then select the Output tab.
- Now you need to find out exactly where you want to cut the file. If you are not sure how long your video file is, just open it in a VLC video player. From there, you should have no trouble finding the length of the video file. As illustrated in the screenshot below, the video file I use as an example is 18 minutes and 48 seconds long. Divide in half, that's 9 minutes and 24 seconds per file.
- Locate the Splitting panel within MKVToolNix and select After expiry period from Split mode: menu. Enter the time you want the video to be shared in the box Duration: which in my example is 9 minutes and 24 seconds. Obviously, you don't need to cut the file exactly in the middle – it can be anytime. Finally, enter 2 in the box Maximum number of files: . This will ensure that the resulting "split" only creates two files. Note: one file may be one second or two longer than the other. MKVToolNix does a fantastic job of cutting files in half, but there are times when it is forced to make one file slightly longer than the other.
- After configuring the options in the Splitting panel, click the Start Multiplexing button located at the bottom of the window.
- When you're done, you can find the two newly created video files in the same folder where the source file is located.
- Open each one to confirm that everything went smoothly. All ready!
