MP4Tools is an open source set of utilities for merging or splitting video files

Video modifying may be an awfully difficult job in the event you’re not utilizing the fitting instruments. If all you want is to easily be a part of, or lower some movies, what you could want is a easy program.

MP4Tools is an open source set of utilities for merging or splitting video files

MP4Tools does exactly that. It comes with two unbiased modules: MP4Joiner and MP4Splitter. MP4Joiner can be a part of (or merge) two or extra movies right into a single MP4 file. MP4Splitter does the alternative, i.e. it splits it into a number of files.


The utility has a toolbar on the prime that permits you to add or take away movies from the queue. Despite being known as MP4Joiner, this system does help a number of further video codecs: MP4, M4V, TS, AVI and MOV.

One you add some movies to be merged, you will note the media data within the giant clean pane beneath the toolbar. This contains the video’s path, length, measurement, codec, decision and side ratio. Use the arrow buttons in the direction of the fitting edge of the display to re-order the movies.

MP4Joiner video cutter

Right-click on a video to take away or type it, however extra importantly it has a “Cut Video” possibility. Using it lets you use the built-in video cutter. This instrument is very straightforward to make use of, simply the beginning and finish time positions and click on okay. The video will not be lower instantly, however the change shall be processed throughout the merge operation.

The statusbar on the backside of the interface exhibits you what the whole length and measurement of the output video shall be. Observe the standing bar and you will see that I’ve lower one of the movies, so the output video is shorter and its file measurement is correspondingly smaller. Click the choices button on the prime to switch the output settings. You can use it to set the audio bitrate, pattern price, video fixed price issue, preset, and so forth.

Hit the “Join” button on the toolbar and MP4Joiner will open a save dialog field prompting you to decide on the video’s title and placement. Clicking save begins the media merging course of.

The chosen video files are re-encoded and saved as one video. The time taken for the merging course of to finish is determined by the video’s decision and measurement. When I merged two brief 4K movies it took over a minute and a half, merging 720p movies (about 768MB) took practically 10 minutes and the CPU utilization was fairly excessive. Do notice that these had been carried out with a number of functions working within the background. Further exams which included SD, smaller HD movies resulted in quicker merging speeds and decrease CPU utilization.


The interface is a bit completely different, however this system is fairly user-friendly. The “Open Video” button is used to load a video. MP4Splitter helps the next video codecs: MP4, AVI, MKV, MOV, MPEG, MPG, MTS, OGG, OGM, WEBM and WMV.

MP4 Splitter

When a video is loaded, this system shows a preview of it within the left pane. Use the play button to view the video. Use the slider or the timer to select the purpose from which the video needs to be break up, and click on on the “Add break up level” possibility. This will break up the video into two elements, splitting it on the time you may have chosen. You can of course create extra break up factors to interrupt it down additional.

Note: The utility stored crashing when the play button was used. But it really works simply high-quality when including break up factors, and the break up course of was profitable. I am undecided why it crashed, particularly because the preview panel displayed the frames of the break up factors accurately. A fast search on this system’s SourceForge page revealed an analogous concern reported by a person. This means that it could possibly be a bug within the latest model.

The sidebar on the fitting lists your break up factors, and you could take away those you do not need. Clicking the “Start Splitting” button will immediate you to pick a folder the place the output movies shall be saved in. When you choose the folder, video splitting course of will start, wait till its full and the movies shall be prepared to make use of. MP4Splitter was surprisingly quicker than the joiner instrument, even when working 1080p 60fps movies.

Both applications within the MP4Tools suite use FFMPEG for encoding movies. MP4Tools is a 32-bit software program. It is out there for Windows and macOS. Linux customers should compile it from the source code. It is not a conveyable utility.
