15. AVI-Mux GUI
Another simple application that can help you mix audio and video files is AVI-Mux GUI. The application offers a humble user interface, and in order to mix two or more files, you just need to add them to the application.
After doing that, you can add the file title and set the desired resolution. If needed, you can choose not to use audio or to use all audio streams. In addition, you can apply the same options to the subtitles.
You can set a delay for all available tracks, and there’s also support for chapters. If needed, you can choose which tracks you want to use. As a result, you can easily use two or more audio tracks simultaneously. Of course, you can also completely remove the original audio track and replace it with a new one.
AVI-Mux GUI also allows you to configure some output settings and you can choose between AVI and MKV output format. If needed, you can also split output files based on their size. In addition, you can also set the specific configuration for MKV and AVI files.
The application is rather fast and you’ll be able to mix audio and video files in a matter of seconds. AVI-Mux GUI is a simple application and it doesn’t offer any editing features, so you won’t be able to trim videos or audio files.
On the other hand, the application is relatively simple to use, so you should be able to mix audio and video files with ease. This tool is completely free, and it will work on any PC without an installation.
Another useful application that can help you mix audio and video files is FormatFactory. This is a file converter software, and it works with a wide array of formats.
As for the video, it allows you to convert your files to MP4, MKV, AVI, WebM, 3GP, MWV, FLV, SWF, GIF, and several others. If needed, you can also choose to optimize your files for various video devices.
The software can also convert files to MP3, WMA, APE, FLAC, AAC, AC3, WAV, OGG and many other formats. In addition to audio and video files, FormatFactory also works with images, so you can convert images to WebP, JPG, PNG, GIF, ICO, and several other formats.
The application also works with DVD and CD discs allowing you to easily rip both DVD and audio CDs. If needed, you can also convert any DVD or CD to ISO. Even though this is a file converter, it offers some hidden features, such as the ability to join video or audio files.
The application also offers a powerful rename ability as well as the ability to mix audio and video files.
As for video mixing, you can output your file to MP4 or MKV format. Of course, you can customize various parameters for your output file including video encoder, bitrate, FPS, audio stream quality, etc.
After you add the desired audio file, you can disable its audio track or keep it. If needed, you can also view video information or trim the unnecessary segments. Video cropping is also available so you can resize your video with ease. After doing that, you just need to add a desired audio file and you’re good to go.
FormatFactory is a solid media converter, but it also offers video and audio mixing along with other features. If you need a media converter that can also mix audio and video files, we recommend you check out FormatFactory. The application is free to use, so be sure to try it out.
17. MKVToolNix GUI
If you want to mix audio and video files and save the results in MKV format, you might want to consider using this tool. The application has a simple user interface, so you shouldn’t have any problems with it.
To mix audio and video, you just need to add the desired files to the application. After doing that, you’ll see all available chapters, tracks, and tags. Now you can choose which tracks you want to use and save the output as an MKV file.
In addition, you can select any available track and change various options. For example, you can add a delay or choose to stretch the track. If needed, you can also set the desired aspect ratio or crop the file.
As for output settings, you can add global tags or segment info to your files. In addition, you can split your output file using several splitting modes.
As for additional features, the application has a chapter editor and a job queue so you can process multiple files. We have to mention that the application is rather fast, and you’ll create your files in a matter of minutes.
MKVToolNix GUI can only output MKV files, and that’s our only complaint. If you don’t mind this limitation, feel free to try this application out. We also have to mention that this tool is completely free and it can run without installation.
Mixing audio and video is relatively simple as long as you have the proper tool to do that. We covered a wide range of tools for audio and video mixing, so feel free to try any of them.
