The device processor performs decoding and encoding during the job during this F4V-to-MP4 job.
Available memory can limit very large F4V conversion jobs.
Keep the source until the MP4 result passes a full playback check.

MP4 serves phones, browsers, players, and upload forms, whereas F4V commonly serves older Flash publishing systems.
For F4V-to-MP4 delivery, plan for destination-specific internal codec rules.
After leaving F4V, the receiving app must support the streams encoded inside MP4, not only its extension.

F4V to MP4 taking too long? Try a small source first to separate a performance issue from a format issue.
MP4 converted from F4V not opening? Test a compatible player and inspect the output streams.
A MP4 extension alone may not be enough; verify the required internal codec.

When does F4V to MP4 conversion make sense?

It is useful when F4V media created for legacy web archives must enter a MP4 system designed for general playback and sharing.

Where is the F4V source processed?

The browser prepares MP4 from F4V on this device instead of sending the source to a remote conversion server.

How can I approve MP4 converted from F4V?

Test the MP4 file in the receiving app and compare duration, picture, sound and timing with the F4V source.
