downloading video: audio broken

[yreew]

I was trying to download this video: [url]https://www.vidio.com/watch/26822-para-pencari-tuhan-jilid-1-episode-01[/url] using this [url]https://9xbuddy.com/process?url=https%3A%2F%2Fwww.vidio.com%2Fwatch%2F26822-para-pencari-tuhan-jilid-1-episode-01[/url] and vlc. so what i did was Open Media > Network > Convert. the settings i used was keep the original audio and video and the encapsulation is mp4. i chose the them as i dont know anything what those all mean.
the result was the audio doesnt sync but the video is fine i think.
i tried other encapsulation options but none worked either.
what should i do to make it right?

i am using linux (arch) and current latest version.
