Encoding speed depends on the processor available to this tab during this H.265-to-FLV job.
Duration, resolution, and source bitrate affect how quickly H.265 is processed.
Review the beginning and end of FLV after the download finishes.

FLV serves archived Flash players and publishing systems, whereas H.265 commonly serves newer devices and storage-conscious delivery.
For H.265-to-FLV delivery, plan for no native playback in current browsers.
After leaving H.265, the receiving app must support the streams encoded inside FLV, not only its extension.

H.265 to FLV taking too long? Close other demanding apps, then test a short sample before the full file.
FLV converted from H.265 not opening? Test a compatible player and inspect the output streams.
Check whether the receiver supports this FLV variant: no native playback in current browsers.

When does H.265 to FLV conversion make sense?

It is useful when H.265 media created for efficient modern encoding must enter a FLV system designed for legacy streaming projects.

Where is the H.265 source processed?

The browser prepares FLV from H.265 on this device instead of sending the source to a remote conversion server.

How can I approve FLV converted from H.265?

Test the FLV file in the receiving app and compare duration, picture, sound and timing with the H.265 source.
