FLASH Video to SNDR conversion is the process of transforming a video encoded in the FLV (Flash Video) container—commonly used for web streaming and containing codecs like Sorenson Spark, H.263, or H.264—into the SNDR format. This conversion repackages or transcodes the media to the SNDR target specification so it can be played or processed by applications that require the SNDR format.
