- Description
- Smacker Video (.smk) is a video file format developed for use in video games, designed to deliver synchronized audio and video with efficient compression on low-end hardware. It was especially popular in the 1990s and early 2000s for cutscenes and in-game full-motion video. The format supports multiple audio tracks and palette-based video compression optimized for CPU playback without dedicated hardware acceleration.
- RealPlayer created RA for audio streaming. It makes use of various audio codecs from those that deliver high-fidelity sounds to those that record low bitrate audio data. Radio stations mainly used it for online streaming, but current formats have overthrown it.
