How to convert M4V to F4V
To convert M4V to F4V, upload your M4V file, choose F4V as the output format and press Convert. The finished F4V file is ready to save to your phone or computer in seconds, free, with no watermark and no sign-up. Your file is deleted from our server about 30 minutes after the conversion.
This free online converter turns M4V videos into F4V files in your browser, with no software to install and no watermark. When the video and audio inside your M4V file can be placed in F4V as they are, the streams are copied without re-encoding, which is faster and keeps the original quality. Otherwise the video is re-encoded as H.264 video with AAC audio.
Reasons to switch from M4V to F4V
- H.264 quality inside a Flash-era container
- Plays in many legacy Adobe tools
- Efficient compared with classic FLV
- Plays on: VLC, Adobe tools and many media players
What to expect from this conversion
- Expect a file of similar size to the M4V original.
- Flash is discontinued, so F4V files play in desktop players and legacy tools rather than in browsers.
- Videos bought from iTunes may be copy-protected. DRM-protected files cannot be converted by any tool, but your own M4V recordings work fine.
- F4V is a legacy format. Convert to it only when an older player or device requires it, since M4V is better for everyday use.
- The first audio track is kept. Subtitle tracks, extra audio tracks and chapters are not included in the converted file.
