Starting point: FLV - FLV is Adobe's Flash-video container carrying Sorenson Spark or H.264 streams. Flash-era players are gone, so convert for current browsers. Interlaced sources may need deinterlacing for clean playback. Encode MPEG (MPEG-2 / MP2) from FLV at a bitrate near the source, and confirm the audio track before converting.
