Audio (mp3) extraction problems from mp4

Jason_Zhang

I started using Prism a long time ago. I still remember the days when I used version 5.0.

I recently updated to v11.15, and was about to extract some audio from mp4 files, but I'm running into this problem. See in the clips:

Prism Always loading when extracting mp3 from mp4

Just so I thought the problem was solved after hearing the conversion was completed,

The length of the mp3 is 12 HOURS

Can someone help? Thanks a bunch

What's the size of the mp4 source file? Is it too large to be uploaded a free file sharing server?

If not, link the file here for testing.

The mp4 source file is 8.99MB, I don't think that's something that can be called "too large." I certainly hope I'm not wrong.

But here's the Google Drive link to the file:

Though it plays in a viewer, the file appears to be Dash streaming encoded, which doesn't sit well with Videopad - no audio, or another editor - no video.

Re-encoding it with this free utility solved those issues, and it should work in Prism as well.

There are numerous ways to extract the audio.

Thanks a bunch, didn't know these hidden encoded stuff would mess with Prism, will use the free utility from now on.
