Convert AIFF to MP4
What is AIFF?
AIFF
AIFF stores pure audio waveform data without visual components. Video requires image frames synchronized with audio. AIFF provides the audio track—creating video also requires visual content. You'd need to combine AIFF audio with an image sequence or video source.
- AIFF contains pure audio data requiring video track addition for video output
What is MP4?
MP4
MP4 containers hold multiplexed video and audio streams, typically AAC-compressed at 128-320 kbps. The audio track synchronizes with video frames at 24-60fps using timestamps. Extracting audio to formats like MP3 or WAV means demultiplexing—isolating the audio stream from the container. This is straightforward stream separation without quality loss if using lossless extraction.
- MP4 combines video and audio streams in a container, allowing audio track extraction
- Contains separate audio track easily extracted to AIFF format
- Video stream discarded—only audio codec and bitrate matter
- Universal browser and device support—no compatibility concerns
