Video File Splitter

advertising

If you are using the wrong tool, video editing can be a very complex task. If you just need to simply add or cut some videos, then you may need a simple program.

MP4Tools does exactly this. It comes with two independent modules: MP4Joiner and MP4Splitter. MP4Joiner can merge (or merge) two or more videos into a single MP4 file. MP4Splitter is the opposite, which splits it into several files.

There is a toolbar at the top of the app that allows you to add or remove videos from the queue. Despite being called MP4Joiner, the program does support some other video formats: MP4, M4V, TS, AVI and MOV.

After adding some videos to be merged, you will see the media information in the large blank pane below the toolbar. This includes the path, duration, size, codec, resolution, and aspect ratio of the video. Use the arrow buttons on the right side of the screen to reorder the videos.

Right-click the video to delete or sort it, but more importantly, it has a "cut video" option. Using it allows you to use the built-in video cutter. The tool is very easy to use, just click OK at the start and end time. The video will not be cut immediately, but the changes will be processed during the merge operation.

The status bar at the bottom of the interface displays the total duration and size of the output video. Looking at the status bar, you will see that I have cut one of the videos, so the output video is shorter and the file size is correspondingly smaller. Click the option button at the top to modify the output settings. You can use it to set audio bitrate, sample rate, video constant rate factor, presets, etc.

Click the "Join" button on the toolbar, and MP4Joiner will open a save dialog box, prompting you to select the name and location of the video. Click Save to start the media merge process.

The selected video file will be re-encoded and saved as a video. The time required for the merging process to complete depends on the resolution and size of the video. When I merged two short 4K videos, it took an hour and a half, merging 720p videos (approximately 768MB) took nearly 10 minutes, and the CPU usage was high. Please note that these operations are performed by multiple applications running in the background. Further tests include standard definition, smaller HD videos, resulting in faster merging speed and lower CPU usage.

The interface is slightly different, but the program is very user-friendly. The "Open Video" button is used to load the video. MP4Splitter supports the following video formats: MP4, AVI, MKV, MOV, MPEG, MPG, MTS, OGG, OGM, WEBM and WMV.

After the video is loaded, the program will display its preview in the left pane. Use the play button to watch the video. Use the slider or timer to select the point from which the video must be split, and then click the "Add Split Point" option. This will split the video into two parts, which will be split when you choose. Of course, you can create more split points to further subdivide it.

Note: The application keeps crashing when using the "Play" button. However, it works well when adding split points, and the splitting process has been successfully completed. I'm not sure why it crashes, especially because the preview panel displays the frame of the split point correctly. Quick search program

Reveals similar issues reported by users. This indicates that it may be a bug in the latest version.

The sidebar on the right lists your split points, and you can delete unnecessary split points. Clicking the "Start Split" button will prompt you to select the folder where you want to save the output video. After selecting the folder, the video splitting process will start, wait for it to complete and prepare to use the video. Even when processing 1080p 60fps video, MP4Splitter is much faster than the joiner tool.

Both programs in the MP4Tools suite use FFMPEG to encode video. MP4Tools is a 32-bit software. It is suitable for Windows and macOS. Linux users will have to compile from source code. It is not a portable application.

For windows

Is this a lossless editing program like LosslessCut, or is it re-encoding, which leads to a decrease in video quality?

From the time it takes, it will be re-encoded.

Any front end of IMO FFMPEG should show whether the final operation will include re-encoding.

Add multiplex

Just use Avidemux to meet all your merge/split needs.

Of course, Avidemux is great, but it cannot merge different videos such as aspect ratio and/or codec.

But I don't even know if MP4Tools can do this, because Ashwin's report here is rather lacking in this kind of testing. It seems OK, but IDK.

Now, I know that Video Combiner can combine various video types into one, but the free trial version sucks because after the trial period ends, the final version of the video has a huge watermark.

Martin reviewed Video Combiner in 2019, but it didn't go well.

That is, I don't fully believe in ghacks anymore, and I now need other trustworthy opinions before trying to use such software.

In addition, I saw some other suggestions in the comments.

Hey, Ashwin, this article looks like you need a tool, googled one, chose the first one, and wrote it after using it.

However, the fact that you wrote means but does not mean that it is superior to other similar tools (they are just the front end of FFPMEG).

Compared with similar tools (for example, avidemux and losslesscut), it is more useful.

Martin or Ashwin,

Thanks for your article.

Is it possible to write relevant reviews

?

I increasingly have the impression that even if there is not much material or topic worth writing, the space in the ghacks newsletter must be filled week after week.

This was not so obvious until Martin sold his store. But now it looks like production, production...

Does ghacks have anything to prove or prove to the new owner?

If you are not interested, do not write in vain, please fill in some blanks in the comics.

I am using it, but I am having difficulty reading the guide. Hope Martin will create a guide/code such as reducing mp4 file size without reducing quality

I am new to this developer forum. I want instructions on how to compile the source code of this tool.

@JohnC. I know of lossless editing programs like LosslessCut, which will not re-encode your media files. This is the TunesKit video cutter, which will cause the video quality to drop.

Whether you want to create video content for your YouTube channel or create a movie from any recording, you need some application that can divide the video into multiple parts as needed. When cutting a video file into two parts, the quality and safety of the file are also necessary, so that you can cut the video without losing any material. In this article, we will discuss some of the best video splitter applications on the market. We will briefly discuss the pros and cons of each listed application. Read the full text and decide which one is best for you, or you can download the app from the given link.

Please also keep in mind that depending on your project, video editing, video splitting and merging can be very complicated tasks. Therefore, we have selected some of the most powerful but easy-to-use applications to complete this work. Although there are other such applications on the market, their operations are much more complicated, but due to their advanced utilities, some of them are very useful and powerful. However, for ordinary users, we decided to adopt the options discussed below that are easy to learn.

If you lack the old Windows Movie Maker, but you can’t use it now, please try to use the default Windows 10 video editor software. The software comes with the Windows 10 operating system and can be accessed directly from "Apps". Although it does not provide extensive video editing functions, simple trimming, splitting and basic editing can be done very easily.

:

If you are a Windows 10 user and are looking for a better option due to the shortcomings of the application, then I recommend you to use MiniTool MovieMaker for stable performance and expected results.

As the name suggests, MiniTool MovieMaker is a complete video editing software, but it also contains a powerful tool, Video Splitter. MiniTool MovieMaker is an easy-to-learn and easy-to-use video editing software. MiniTool MovieMaker is a free application that can be used by all users. Unlike many other free MovieMaker applications, MiniTool does not add any watermark to the final product, so in the end you will get a brand new video file. As I said, the video splitting tool is very powerful, because not only can you precisely reduce a part of any video, but you can also merge these reduced videos with other videos using the same application. If you are eager to edit video quickly, then MiniTool may be a very viable option.

We all know VLC because it is the most popular and free to use open source media player application. However, few people know that VLC itself also has many other useful tools. You don't need to download anything else, you only need the VLC player already installed in your PC to have these tools, and it may become your favorite Video Splitter application. Although VLC is not a powerful application for video editing, it can complete the basic work related to video segmentation and recording. The advanced recording tool in VLC player allows you to divide large videos into several parts.

In short, it is not a full-featured video or audio splitting application, but it records the target part and provides the part as a separate file. Although I have included VLC in this list because it is free, it is available to everyone and can do basic work. Therefore, if you just want to cut some video clips to make screensavers, live wallpapers or memes, then VLC is an ideal alternative to exquisite tools.

Among all video formats, MP4 is the most popular video format on all devices and platforms. If you want to split MP4 video files, you can try the open source MP4 video splitter tool. This tool contains two functions, one function is to split video files into multiple segments, and the other is to merge multiple video files into one.

Of course, if there is no Mac-based application, the list will be incomplete, and we all know that in the case of video editing, iMovie is one of the best applications among all applications. Just because everyone doesn't own a Macbook, that's why many of us need to use some other applications for video editing, splitting and merging. If it is used for iMovie, then most of us will not use any other alternative applications. Yes, iMovie is good, and Mac users can easily perform video splitting, merging, and editing tasks using the toolset that comes with the iMovie application. The results are very good, you can also trim the video, add text to the video, add special effects to the video or any specific clip, and even add an external audio track to the video.

Most users regard Format Factory as a multifunctional audio video converter application. The format factory supports most video and audio formats, and you can also use the format factory tool to restore old video clips from old DVDs. Although it is the main video converter and video extractor, it also has tools that can be used to split video clips. You can also use some of the other tools provided, and the user can merge multiple video clips into one.

format factory

Another wonderful split video application that can be downloaded and used for free without adding a watermark. OpenShot is a very trustworthy and reliable video editing application, suitable for basic to intermediate work. Since it is a full-featured video editing application, it contains several tools that can be used to easily split and merge video material.

Movavi Split Movie is another application for Mac users, it is a basic video editing application that everyone can use. You don't need to be an expert video editor, but it takes some time to understand the UI and its functions. Because this application is powerful, but not so simple in terms of UI. This application is only suitable for basic video segmentation and trimming functions. Especially if you are looking for a video trimmer instead of a splitter, then Movavi Split Movie will be the right choice for you.

I will save this as the last one because Filmora Video Editor is one of the best video editing applications out there. Although like other Filmora apps, Filmora Video Editor is not a free-to-use app, because at the end of this list, I will be talking about a completely professional app here. Yes, when it comes to video editing, Filmora Video Editor is a complete software package, so video splitting, merging, etc. are only functions of this application.

Select the application according to your needs. If you are not a professional, it is not recommended to invest in paid applications, as there are many open source free software devices to choose from. However, if you are a professional, or especially if you are a student, then it is recommended that you start using iMovie and Filmora, because you will need to use these products in your work in the future. However, if you are looking for a dedicated video splitter, then choosing an open source video splitter is sufficient. If you are keen to learn video editing for Facebook posts or YouTube channels, then OpenShot and MiniTool are best for starting and learning, and they are both free.

LosslessCut is a simple cross-platform video editor that can perform lossless trimming/cutting on videos. Very suitable for rough processing of large video files obtained from cameras, GoPros, drones, etc. Allows you to quickly extract the good parts from the video and discard GB of data without loss of quality. It does not perform any decoding/encoding, so it is very fast. It also allows to take a JPEG snapshot of the video at the selected time. Also supports lossless cutting in the most common audio formats.

Since LosslessCut is based on Chromium and uses an HTML5 video player, not all formats supported by ffmpeg will be supported. The following formats/codecs should generally be used: MP4, MOV, WebM, MKV, OGG, WAV, MP3, AAC, H264, Theora, VP8, VP9 For more information on supported formats/codecs, please see https : //Www.chromium.

Unix Dweeb,

The Linux system provides a very easy-to-use command for breaking files into pieces. You may need to do this before uploading the file to a limited file size or emailing it to a storage site as an attachment. To split a file into multiple fragments, just use the split command.

By default, the split command uses a very simple naming scheme. File blocks will be named xaa, xab, xac, etc., and, roughly, if you break up a large enough file, you might even get blocks named xza and xzz.

Unless you request it, the command will not give any feedback at runtime. However, if you want to see them when creating file blocks, you can use the --verbose option.

You can also facilitate file naming by providing a prefix. For example, to name all the contents of the original files bigfile.xaa, bigfile.xab, etc., you can add the prefix to the end of the split command as follows:

Note that a dot has been added to the end of the prefix shown in the above command. Otherwise, the file will have a name like bigfilexaa instead of bigfile.xaa.

Please note that the split command does

Delete the original file and only create the block. If you want to specify the size of the file block, you can use the -b option to add it to the command. E.g:

The file size can be specified in kilobytes, megabytes, or gigabytes, up to yobytes! Just use the appropriate letters from K, M, G, T, P, E, Z and Y.

If you want to split the file based on the number of lines in each block instead of the number of bytes, you can use the -l (line) option. In this example, each file will have 1,000 lines, of course, the last file may have fewer lines.

If you need to reassemble the files on a remote site, you can easily do this using the cat command as shown below:

Splitting and reassembly using the commands shown above should be applicable to binary files and text files. In this example, we split the zip binary file into 50 KB blocks, reassembled them using cat, and then compared the assembled file with the original file. The diff command verifies that the files are the same.

At this point, the only thing I should pay attention to is that if you use split often and use the default naming, you may end up being overwritten by other blocks, and sometimes there may be more blocks than you expected because some of them are left of. Some earlier splits.
