WEBM to SWF conversion is the process of transforming a video file encoded in the WEBM container (commonly using VP8/VP9 video and Vorbis/Opus audio) into an SWF (Small Web Format) file, which packages multimedia and vector graphics for playback in Flash-based environments. This conversion remuxes and/or re-encodes the video and audio into codecs and structures compatible with SWF so legacy Flash players or authoring tools can use the content.
