Random distorsions in mp4 after export

Hi there. I sometimes have 2 problems in videos after export: random audio distorsion for 0.5-1 second or just a complete silence for 1-3 seconds. If I reexport from Screenflow once again it is always fine. Normally it happens once per 15-20 videos so I have to recheck all them by hand because I can't be sure that there is no distorsion there.

My setup:

Mac mini 2018

Catalina 10.15.4

Screenflow 9.0.3

No computer audio recording

Focusrite + Procaster mic


In export I'm choosing Manual -> Web high. No additional configuration

Any idea how to fix it or what can cause it?

  • What is the source of the audio? Is this always the Focusrite or is an imported file involved?
    Do you have a sample problem export you could send us?

    If so, fill out the form and when we email you the case number, send us back a link to the file.
