Looking for a simple way to convert RMVB files to MP4? WALTR PRO offers an intuitive solution for both Windows and Mac users with just a few clicks.
Understanding Video Formats
What is RMVB?
RMVB (RealMedia Variable Bitrate) is an older video format developed by RealNetworks. It was popular in the early 2000s for its ability to maintain reasonable quality at lower file sizes. However, it has limited compatibility with modern devices and software.
What is MP4/M4V?
MP4 (MPEG-4 Part 14) is a digital multimedia container format most commonly used to store video and audio. M4V is essentially the same container format but developed by Apple specifically for iTunes content. Both provide excellent quality while maintaining reasonable file sizes and have widespread compatibility across devices and platforms.

The RMVB to MP4 (Actually M4V) Conversion
When you convert videos using WALTR PRO, the output is technically in M4V format rather than MP4. Don't worry though - M4V is Apple's version of the MP4 container format. The main difference is that M4V files can include DRM protection for iTunes content, but in practical terms, they function nearly identically to MP4 files. Most media players that support MP4 will also play M4V files without any issues.
This conversion to M4V happens because WALTR PRO was designed with Apple device compatibility in mind. The M4V format ensures your converted videos work flawlessly on iPhones, iPads, and other Apple devices.

WALTR PRO handles more than just RMVB files. It supports various conversions including:
- ts to mp4
