Converting FLV to MP4: what to know
FLV is the Flash video format that websites once used to show videos; such files remain in old archives and downloads. Modern players and phones barely open them, while MP4 plays everywhere.
The video is re-encoded to H.264, and the sound is carried over into the MP4. While converting, you can trim the video, change its resolution and remove the sound.
FLV or MP4: which to choose?
FLV (Flash Video)
FLV is the Adobe Flash video format that websites once used to show videos.
Best for old archives of website videos - for watching, convert them to MP4.
MP4 (MPEG-4 Part 14)
MP4 is the most compatible video format: it plays on phones, TVs, browsers and social networks.
Best for publishing and sending videos - maximum compatibility at a reasonable size.
What happens when converting FLV to MP4
If the codecs inside FLV are supported by MP4, the tracks are copied without re-encoding - quickly and without quality loss. Otherwise the video is re-encoded with the codec, bitrate, resolution and frame rate you choose.
You can also trim the video, rotate or flip it and remove the sound.
FLV files up to 2 GB are supported; the actual limit also depends on the free memory of your device.
