If you notice a significant amount of crackling

• 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

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

Select Convert, add file then select Convert again
