Flash MP4 Video
Source formatF4V is an Adobe Flash-compatible video container based on the ISO base media file format (similar to MP4). It was used by Flash Player to deliver H.264 video content on websites before HTML5 video became the standard.
Flash Video
Target formatFLV was the dominant web video format during the Flash era. While Flash is now deprecated, many legacy video files still exist in FLV format and need conversion to modern formats.
Why convert F4V to FLV
La conversión de F4V a FLV es habitual en producción de vídeo para adaptar el material a las especificaciones de entrega de cada plataforma.

Frequently Asked Questions
Frequently Asked Questions
Only when it has to. If the codecs inside F4V (usually H.264 or H.265 for video, AAC for audio) are accepted by FLV, we stream-copy — the bytes are repackaged into the new container with zero re-encoding and no quality loss. When the source uses a codec the target does not support, we transcode at a matching bitrate to keep the visual quality close to the original.
With stream copy, expect the job to finish in seconds to tens of seconds regardless of video length — the work is mostly rewriting the container. Transcoding is slower (roughly real-time: a ten-minute clip takes about ten minutes) because every frame must be decoded and re-encoded. The progress bar shows which mode applies.
Yes. Resolution, frame rate, colour space and bit depth are preserved by default; stream copy is literally bit-identical on these parameters. If you explicitly pick a lower bitrate or a different codec in Advanced, the output is rebuilt to those settings, but the default is always "match the source".
