MP4 is a multimedia container format that can store video, audio, subtitles, and images. It’s the most common format for online video streaming and playback, supporting high compression and broad compatibility. MP4 is often used with H.264 and AAC codecs.
AAC stands for Advanced Audio Coding and is a lossy audio format known for its high sound quality at lower bitrates. It’s commonly used by streaming platforms and devices like iTunes, YouTube, and iPhones. Compared to MP3, AAC offers better audio performance at similar file sizes.
