What is a FLV file?

FLV was the Flash Player video format behind early YouTube. Flash is gone, so FLV files now need converting before modern devices will play them. It is a lossy format best suited to old recordings from the Flash era. The main drawback is that no modern browser or phone plays FLV.

Frequently asked questions

Will the MP4 lose quality?

Both formats are lossy, so converting re-encodes the data once more. Using a high quality setting keeps the generational loss very small. Avoid converting the same file back and forth repeatedly.

Does converting FLV to MP4 re-encode the video?

Sometimes: it depends on the codec inside your file, and Smart mode checks this automatically. A typical FLV contains H.264 or Sorenson Spark video with AAC or MP3 audio. Otherwise the result is H.264 with AAC audio.
