Comparison with other formats

When choosing between 4K MP4, 4K MKV, and 4K WEBM, consider the following:

• — Both can carry 4K video; MP4 is generally more universally supported on devices and editors, while MKV can offer more flexible audio/subtitle options and is popular in desktop playback. File sizes can be similar, depending on codecs chosen..
• — WEBM with VP9/AV1 can offer excellent compression efficiency, but some devices and editors may have limited support for VP9/AV1 in 4K. If broad compatibility is essential, MP4 is the safer choice..
• — If you only need audio, MP3 and AAC are widely compatible. WAV offers high quality but larger file sizes, while Opus can provide efficient, high-quality audio at lower bitrates..
