Processing demand varies with the codecs found in the source during this WMV-to-M4V job.
Duration, resolution, and source bitrate affect how quickly WMV is processed.
Inspect the M4V file in the exact player or editor that will receive it.

M4V serves Apple-oriented libraries and players, whereas WMV commonly serves Windows Media players and older presentations.
For WMV-to-M4V delivery, plan for differences from protected store content.
After leaving WMV, the receiving app must support the streams encoded inside M4V, not only its extension.

WMV to M4V taking too long? Close other demanding apps, then test a short sample before the full file.
M4V converted from WMV not opening? Test a compatible player and inspect the output streams.
Match M4V resolution, rate, channels, and codec to the published delivery rules.

When does WMV to M4V conversion make sense?

It is useful when WMV media created for Windows playback must enter a M4V system designed for Apple media workflows.

Where is the WMV source processed?

The browser prepares M4V from WMV on this device instead of sending the source to a remote conversion server.

How can I approve M4V converted from WMV?

Test the M4V file in the receiving app and compare duration, picture, sound and timing with the WMV source.
