Video Encoding Explained: Encoding vs Transcoding vs Codecs

Video encoding compresses raw video frames into network-ready streams by using codecs such as H.264, VP8, VP9, and AV1, balancing visual quality, bitrate, latency, and computing resources; transcoding differs by decoding an existing compressed stream before re-encoding it at another codec, resolution, or bitrate. Codecs determine how video is compressed, while containers such as MP4 and WebM package video, audio, and timing information. Hardware encoders like NVIDIA NVENC, Apple VideoToolbox, and Android MediaCodec reduce CPU use, whereas software encoders such as x264 can provide greater tuning flexibility. Real-time video applications must encode frames as they arrive, generally avoid delay-inducing B-frames, adapt bitrate to network conditions, send keyframes when requested, and often use simulcast to provide several quality layers for different viewers. VideoSDK’s JavaScript SDK supports VP8 by default alongside H.264, VP9, and AV1, with presets controlling resolution, frame rate, bitrate strategy, optimization behavior, and simulcast, while server-side tools handle broadcast, RTMP output, recordings, and file transcoding.
