• That can be from:
• Poorly seated microphone &/or connector to video camera
• Interference from adjacent computer &/or large monitors
• Interference from plugs (if plugged in, make sure all in same wall assembly)
• Interference from overhead neon lights
• Solar wind (seriously, magnetic field upsets when northern lights reported)
• Like anything electrical, may be intermittent &/or hard to repeat
• Can almost be cleared with free & easy-to-use video editing software

9. Settings are effectively a filter
• Select ‘Enable’ and ‘2 Pass’ and mimic settings in previous slide
• Play with the settings that eliminate most of the crackling
• You’ll never eliminate it, best you can get is a low level humming
• But that’ll allow video to be heard with no perceptible interference
• You succeeded if reviewer comments on the video not the audio

10. Select Convert, add file then select Convert again
