Conversion uses local memory and processor capacity until completion during this H.264-to-WMV job.
Large H.264 inputs may take several minutes on older hardware.
Inspect the WMV file in the exact player or editor that will receive it.

WMV serves Windows Media players and older presentations, whereas H.264 commonly serves encoders and systems requesting an AVC stream.
For H.264-to-WMV delivery, plan for limited support on non-Windows platforms.
After leaving H.264, the receiving app must support the streams encoded inside WMV, not only its extension.

H.264 to WMV taking too long? Check available memory; long, high-resolution sources need substantially more.
WMV converted from H.264 not opening? Test a compatible player and inspect the output streams.
Match WMV resolution, rate, channels, and codec to the published delivery rules.

When does H.264 to WMV conversion make sense?

It is useful when H.264 media created for technical delivery must enter a WMV system designed for Windows playback.

Where is the H.264 source processed?

The browser prepares WMV from H.264 on this device instead of sending the source to a remote conversion server.

How can I approve WMV converted from H.264?

Test the WMV file in the receiving app and compare duration, picture, sound and timing with the H.264 source.
