| Component | What It Does | Common Choices | |-----------|--------------|----------------| | | Packages video, audio, subtitles, and metadata into one file. | MP4 ( .mp4 ) is default; can also use MOV, M4V. | | Video Codec | Compresses raw frames. | H.264 (AVC) – universal; H.265 (HEVC) – half the bitrate for same quality; AV1 – future‑proof, royalty‑free. | | Audio Codec | Compresses audio stream. | AAC‑LC (most compatible); AAC‑ELD (low‑delay); Opus (high‑efficiency, but not yet universal). | | Pixel Format | Defines chroma subsampling and bit depth. | YUV420p (most compatible), YUV422p (better color detail), YUV444p (lossless). | | Bitrate | Data rate for video/audio. | Measured in kbps; higher → better quality, larger file. | | Resolution & Frame‑Rate | Physical size and temporal smoothness. | 1080p @ 30 fps, 4K @ 60 fps, etc. | | Key‑frame Interval (GOP) | How often full frames are stored. | 2 seconds (e.g., 60 frames @ 30 fps) works for most streaming. | | Moov Atom Placement | Index that lets a player seek. | “Fast‑start” moves the moov atom to the beginning for instant playback. | pppd515mp4 better
