This suggests that it could be a bug in the latest version. A quick search on the program's SourceForge page revealed a similar issue reported by a user. I'm not sure why it crashed, especially since the preview panel displayed the frames of the split points correctly. But it works just fine when adding split points, and the split process was successful. Note: The application kept crashing when the play button was used. You can of course create more split points to break it down further. This will split the video into two parts, splitting it at the time you have selected. Use the slider or the timer to pick the point from which the video has to be split, and click on the "Add split point" option. When a video is loaded, the program displays a preview of it in the left pane. MP4Splitter supports the following video formats: MP4, AVI, MKV, MOV, MPEG, MPG, MTS, OGG, OGM, WEBM and WMV. The "Open Video" button is used to load a video. The interface is a bit different, but the program is quite user-friendly. Further tests which included SD, smaller HD videos resulted in faster merging speeds and lower CPU usage. Do note that these were done with multiple applications running in the background.

When I merged two short 4K videos it took over a minute and a half, merging 720p videos (about 768MB) took nearly 10 minutes and the CPU usage was quite high. The time taken for the merging process to complete depends on the video's resolution and size. The selected video files are re-encoded and saved as one video.

Clicking save begins the media merging process. Hit the "Join" button on the toolbar and MP4Joiner will open a save dialog box prompting you to choose the video's name and location. You can use it to set the audio bitrate, sample rate, video constant rate factor, preset, etc. Click the options button at the top to modify the output settings. Observe the status bar and you'll see that I have cut one of the videos, so the output video is shorter and its file size is correspondingly smaller. The statusbar at the bottom of the interface shows you what the total duration and size of the output video will be. The video won't be cut immediately, but the change will be processed during the merge operation. This tool is very easy to use, just the start and end time positions and click ok. Using it allows you to use the built-in video cutter. Right-click on a video to remove or sort it, but more importantly it has a "Cut Video" option. Use the arrow buttons towards the right edge of the screen to re-order the videos.

This includes the video's path, duration, size, codec, resolution and aspect ratio. One you add some videos to be merged, you will see the media information in the large blank pane below the toolbar. Despite being called MP4Joiner, the program does support a few additional video formats: MP4, M4V, TS, AVI and MOV. The application has a toolbar at the top that lets you add or remove videos from the queue.

MP4Joiner can join (or merge) two or more videos into a single MP4 file.

It comes with two independent modules: MP4Joiner and MP4Splitter.
