MPEG4 Modifier

MPEG4 Modifier is a simple, yet reliable application designed to perform modifications on MPE4 videos and save them without performing an encoding process.
The majority of third-party applications that deal with video resizing or stream editing accomplish their purpose by re-encoding the original file. This is quite an expensive process, both resource and time wise. In order to modify video files, but skip the conversion process, you should opt for an application such as MPEG4 Modifier.
This program is made for the average user and carries out its job without taking a toll on system resources. In addition, all the files it needs are bundled in a ZIP file and no installation is required, which brings the advantage of portability.
Its interface is simple, yet well organized and easy to understand. The application is able to process only one video file at a time, supports only AVI formats and outputs the results in the same format.
Getting to understand how it works is not rocket science. Once you provide the source video file, the application makes available a set of options that allow you to change its aspect ratio (the custom mode allows you to set it to whatever values you want), modify its bitstream, edit user data and change the order of interlaced fields.
As soon as you hit the Save button, the video will be exported to a location of your choice with all the modifications you made included in the result. During our tests, the software carried out tasks on large video files in just seconds and subsequently, preserved the quality of the original.
In conclusion, MPEG4 Modifier is an awesome way to personalize AVI files without having to go through a time consuming conversion process. Its only downside is that it can’t process multiple files at a time.
