I have now tried:
Of course confirmed that the original clip is clean, no issues when playing it back in a normal player.
Both unlinking and keeping the audio linked to the video, no difference.
Exporting the audio as MP3, but this causes the stuttering issue in the exported file.
I tried putting the clip on the timeline, unlinking the audio and opening it from the timeline in Adobe Audition, but when playing it back there, it still has the same stuttering.
The issue happens to all clips downloaded from a particular website, which downloads them as 30fps/22050Hz.
*** How I did get it to work ***
Well time will tell if I’m just lucky or if it actually works. Because I’ve previously tried just being lucky that it worked, simply because I moved the clip a bit on the timeline.
But I downloaded ‘Handbrake’ as you suggested, and loaded my clip in there and basically just exported the clip again with the settings it automatically chose.
Preset: Fast 1080p30
Audio: AAC – Bitrate: 160 – Samplerate: Auto
And by using this exported version of the clip in Premiere Pro, it plays it back normally.
Hopefully this just works it that will have to be my workaround when using clips from this website! 😀
