Download and install this smart MKV video splitter. After running it, you can choose 16:9 or 4:3 ratio option to enter into the main interface of this MKV file splitter.

2. Split MKV files

Drag your wanted MKV file from the album to the Timeline. And then you have two methods to split the MKV file after you select it:

  • 1. Drag the slider bar and the top of the red Indicator to move the Indicator to the exact place you want and then click the Scissor button. You'll notice the large MKV file is split into two parts. (Please note: you need to choose the video before moving the Indicator by clicking it.)
  • 2. Directly drag one video clip to the exact position where you want to split the MKV file, and then delete the added one (because when you add a video clip overlapping in the other, the later video will be split automatically). Of course, you can use this way to add a different video clip in the MKV file if needed.

3. Export the single MKV clip

Delete other MKV clips and just leave a single MKV clip. After that, click the "Export" button to pop up the Output window, hit the Format tab, and then select MKV to export the single MKV clip in one file. By default, Filmora will export the video in Better Quality, but you can change the video encder, resolution, frame rate and bit rate if necessary. It is recommended to export the video with the same or similar settings as the original video.

Open the same project to repeat the delete and export job. In this way, you can make each MKV clip in a simple file.

Actually, I must say I do like the free version letting you mess with everything without buying, because I want to do this as well and found I cannot. I don't want to re-encode large stretches of video in order to cut out a few things. However, I realized that because of their watermarking they HAVE to do this or else they have no control and can't make people pay. It's too bad. The product is fundementally flawed simply because of their approach to demoing the software. @Wondershare... is there any change this works the way we want in the paid version when it doesn't have to add your watermark?
Yeah, hi Wondershare team. I don't have beef with y'all making a blog-style site to "review" your own product and demonstrate its features. But when you lie, you're not helping. The question was... "How to split .mkv files without re-encoding ?? I mean the same exact quality as before. "-Pitorasilo EXACT QUALITY = same datarate/bitrate/framerate for video and same bitrate/samples/channels for audio. Your guide says that if you input an mkv, cut it down to the selected portion you want, and then output without touching things, you get an mkv of the *exact same quality*. Yeah... no. No you don't. I just tried this with an mkv file I had that I did not want to go lossy in any way. it had the following rates: Datarate: 20977kbps Bitrate: 23281kbps Frame rate: 23fps Audio Bitrate: 2304kbps Channels: 2 Audio sample rate: 48 kHz Now, I cut the video to the portion I want, do output with your program (which took surprisingly long for a 3 minute selection), and I got something *highly* encoded, which I did not want! Datarate: 0kbps (?) Bitrate: 10,000kbps Frame rate: 30fps Audio Bitrate: 256kbps Channels: 2 Audio sample rate: 44.1 kHz Now, I *get* that I can go into the program and change encoding settings, but that's not at all what your instructional blog says. Your blog *implies* that your software will either do a true "crop" or "trim" to my source file without changing its parameters whatsoever, OR that it will detect the original file's mkv encoding properties and replicate exactly. It does *neither.* It has a default codec that is somewhat lossy on video and HIGHLY lossy on audio. Your program allows for *some* customization in the mkv encoding process, but I cannot for the life of me get it to match that of my source file. So ... thanks for that. Really, really glad I didn't pay up front and dealt with the watermark while testing this...
