Convert MP4 to MPEG

MPEG (specifically MPEG-1 or MPEG-2) is an older but widely compatible format that works with many legacy systems and specialized equipment. If you're working with older DVD authoring software, certain broadcast systems, or vintage playback devices, MPEG has better compatibility than MP4. It's also sometimes required for specific professional workflows in television and media production. While MP4 is more modern and efficient, MPEG is useful for compatibility with established systems in certain industries and with older equipment.

MP4 is part of the MPEG-4 standard, while what we commonly call MPEG files typically use the older MPEG-1 or MPEG-2 standards. They're related but designed for different eras with different capabilities. MPEG files typically use different compression methods, have different container structures, and offer different compatibility profiles than MP4, despite the related naming. The converter handles the technical details to ensure proper conversion between these related but distinct formats.

Some quality impact is typically unavoidable because MPEG uses older compression technology that's less efficient than modern MP4 codecs. To maintain the same visual quality, MPEG files are usually larger than their MP4 counterparts. The converter creates MPEG files with standard settings. For advanced customization like quality presets, you may need to use video encoding software before converting.

MPEG-1 is good for maximum compatibility with older systems but limited to SD resolution. MPEG-2 supports higher quality and is the standard for DVDs, making it useful if you're creating content for DVD authoring or broadcast systems. The converter creates MPEG files with standard settings. For advanced customization like MPEG variants or specialized presets, you may need to use video encoding software before converting.

The converter preserves video resolution and aspect ratio when possible. However, standard MPEG-1 has resolution limitations (typically maxing out at 352x240 or similar), while MPEG-2 supports higher resolutions comparable to DVD quality or better. If you're converting high-definition MP4 content to MPEG-1, downscaling may occur. For maintaining HD quality, MPEG-2 supports higher resolutions while maintaining compatibility with DVD authoring tools and more modern playback systems.
