How to convert F4V to MTS
- Add your .F4V file - drop it in the box above or click to browse.
- Convert it to .MTS in a few seconds.
- Download your new .MTS file.
What to expect
- Because both formats use H.264 video, the video stream is typically rewrapped rather than re-encoded, so the picture is preserved.
- Audio may need re-encoding to suit the transport-stream container, which is a lossy step, though usually inaudible.
- MP4-style metadata, tags and chapter markers from the F4V do not survive into the MTS container.
Frequently asked questions
Will the video quality drop when converting F4V to MTS?
F4V already carries H.264 video, and MTS (AVCHD) also uses H.264, so the picture can be carried across without re-encoding and without quality loss. The audio may be re-encoded to a format the transport stream expects, which is a minor lossy step at most.
Why convert F4V to MTS?
MTS is the AVCHD transport-stream format used by camcorders and AVCHD-aware editing software, so converting is mainly about getting old Flash-era footage into that kind of workflow. It also produces a stream-oriented container that some hardware players and editors prefer over the MP4-style F4V.
Where will the resulting MTS file play?
MTS plays in VLC on Windows, macOS and Linux and in editors that support AVCHD. General-purpose apps and phones are less likely to open .mts directly than a plain MP4.
What is lost when moving from F4V to MTS?
F4V's container-level metadata and any MP4-style chapter or tagging structure do not carry into the transport stream. The essential video and audio are preserved, but the file is repackaged as fixed-size MPEG-2 transport packets rather than an ISO-BMFF container.
