What changes when you convert MPEG to FLV
This is a full transcode rather than a container swap, because MPEG-1 is not one of the codecs FLV carries. Every frame is decoded and re-encoded as H.264.
Alternate audio tracks are dropped, because FLV carries one audio stream where MPEG allows several.
One practical gain here: FLV is streaming-friendly, so the converted file begins playing while it is still downloading.
Expect the bitrate to move from roughly 5.5 Mbps to about 4.5 Mbps at 1080p, and file size to follow.
FLV dates from 2002 and is not natively supported by modern browsers, so plan on a desktop media player for playback.
About MPEG to FLV Conversion
Converting MPEG to FLV means moving audio out of the MPEG-1/2 Program Stream container, introduced in 1993, and into Flash Video, which arrived in 2002. The two were designed with different priorities, and that is what determines whether this conversion costs you quality, storage, or compatibility.
Developed by MPEG in 1993, MPEG stores audio using MPEG-1, MPEG-2. That codec choice sets the upper bound on what any conversion can preserve.
FLV, from Adobe (Macromedia) and dating to 2002, uses H.264, Sorenson Spark, VP6 and plays natively on 0 of the six platform categories we track. That combination is usually why people convert into it.
After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.
