What to expect
- FLV is obsolete - Adobe Flash Player reached end of life in December 2020 and no modern browser plays
.flvfiles natively. - DRM-protected
.m4vfiles purchased from iTunes or Apple TV cannot be converted by any tool; only non-DRM.m4vfiles can be processed. - Re-encoding from M4V to FLV always causes quality loss - there is no lossless conversion path between these formats.
Frequently asked questions
Can I convert a DRM-protected M4V file to FLV?
No. Apple FairPlay DRM prevents any software from reading the video stream. Only non-DRM
.m4v files - such as those exported from iMovie or Final Cut Pro - can be converted.Will the FLV file play in a web browser?
No. All major browsers removed Flash support after December 2020 and cannot play
.flv natively. If you need web video, convert to .mp4 instead.What codecs does FLV support?
Modern FLV containers accept H.264 video with AAC audio, which gives the best quality. Older FLV used Sorenson Spark (H.263) or On2 VP6, which produce lower quality at the same file size.
Is FLV the same as F4V?
No - F4V is Adobe's newer Flash container that wraps H.264 and AAC more cleanly than FLV, but both formats are obsolete since Flash reached end of life.
