How do I convert MP4 to F4V?

Upload your MP4 file to the MP4-to-F4V converter, select F4V as the output format, and click Convert. If the MP4 uses H.264/AAC, the conversion is a lossless remux and completes instantly; otherwise, the tool re-encodes to H.264/AAC. Download the resulting .f4v file for use in Flash-compatible environments.

How does the MP4 to F4V conversion affect video resolution, audio bitrate, and metadata?

When the source MP4 contains H.264 video and AAC audio, the streams are copied bit-for-bit into the F4V container, preserving resolution, frame rate, audio bitrate, and color profile. Metadata is remapped to F4V's structure; unsupported fields are dropped. If re-encoding is necessary (non-H.264 input), the tool aims to match the original resolution and bitrate, which may introduce minor quality loss.
