How to Convert M2TS to MP4 in 2025
Struggling with M2TS files that won't play on your iPhone? This guide shows you how to quickly convert them to a compatible format using WALTR PRO, making your HD videos watchable on any Apple device.
What is M2TS?
M2TS (MPEG-2 Transport Stream) is a container format primarily used for Blu-ray discs and AVCHD cameras. While it delivers excellent high-definition video quality, it has limited compatibility with many devices—particularly iPhones and iPads.
When you rip a Blu-ray disc, you'll typically find videos with the M2TS extension. These files play fine on computer media players like VLC, Windows Media Player, and others, though some might require specific codecs.
The problem? iOS devices don't support M2TS files at all. Apple's mobile operating system only works with MOV, MP4, and M4V formats. This limitation means you'll need to convert M2TS to MP4 before watching them on your iPhone.

Why MP4 Works Better
MP4 stands as one of the most universally accepted video formats today. It works across virtually all devices, including all Apple products. Converting M2TS to MP4 solves compatibility issues while maintaining video quality.
The good news is that you don't need complicated software or technical knowledge to make this conversion happen.
Understanding the Formats: M2TS, MP4, and M4V
Before diving into the conversion process, let's understand the key differences between these formats:
M2TS Format
M2TS is primarily designed for high-definition video on Blu-ray discs. It supports multiple audio tracks, subtitles, and maintains excellent quality, but has limited device compatibility.
MP4 Format
MP4 (MPEG-4 Part 14) is a highly versatile container format that supports various media types including video, audio, and subtitles. It's widely compatible with most devices and platforms.
M4V Format
M4V is essentially Apple's variant of MP4. When WALTR PRO converts your M2TS files, it actually creates M4V files - which is technically what Apple devices prefer. Despite the different extension, M4V functions identically to MP4 on Apple devices with the added benefit of being optimized for the iOS ecosystem.
Apple developed M4V specifically for its devices, allowing for better integration with Apple's software. WALTR PRO is actually creating M4V files for optimal compatibility with your Apple devices.
Format Comparison Table

iOS Compatibility | Not compatible | Fully compatible |
File Size | Larger | Moderate |
Quality | High (raw Blu-ray quality) | High with efficient compression |
Playback Support | Limited devices | Nearly universal (MP4) / All Apple devices (M4V) |

How Does WALTR PRO Work?
Since Apple supports very limited formats on its devices, you cannot play just any file format that you downloaded from the internet. An M2TS video, for example, is useless on your iOS device until you convert M2TS to MP4. WALTR PRO, with a standalone converter and transfer tool, will convert M2TS to MP4 (actually M4V) while moving the video to your iOS device. The output format will be compatible with any iOS device.
WALTR PRO handles batch processing efficiently too, saving you time when converting multiple files. Just select all your M2TS videos and drop them into the app together.
Converting to M4V provides:
- Complete compatibility with all Apple devices
- Seamless playback on iPhone, iPad, and Mac
- High-quality video preservation
- Direct transfer without iTunes or an iTunes alternative
