On-device encoding can work the processor harder than ordinary playback during this AAC-to-MKA job.
High-resolution AAC footage increases conversion time and memory use.
Review the beginning and end of MKA after the download finishes.

MKA serves multi-track audio archives and flexible containers, whereas AAC commonly serves streaming, mobile playback, and compact delivery.
For AAC-to-MKA delivery, plan for limited support in consumer players.
After leaving AAC, the receiving app must support the streams encoded inside MKA, not only its extension.

AAC to MKA taking too long? Process a shorter section to determine whether file size is the bottleneck.
MKA converted from AAC not opening? Test a compatible player and inspect the output streams.
Match MKA resolution, rate, channels, and codec to the published delivery rules.

When does AAC to MKA conversion make sense?

It is useful when AAC media created for efficient distribution must enter a MKA system designed for advanced audio storage.

Where is the AAC source processed?

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

How can I approve MKA converted from AAC?

Test the MKA file in the receiving app and compare duration, channels and loudness with the AAC source.
