Starting point: YUV - YUV holds raw planar pixels with no container or compression. Dimensions must be set by hand since headers carry no size. Only the embedded video track converts; scripts and buttons are dropped. Encode SWF (Sorenson Spark / MP3) from YUV at a bitrate near the source, and confirm the audio track before converting.
