What is the difference between Delete and Ignore?
Delete cuts the audio out and closes the gap, so the episode gets shorter. Ignore mutes the audio but leaves the gap, so nothing after it moves. Both are reversible, and both remove the words from captions and exports.
Delete is the right default for speech junk. An ignored filler word leaves a small silent hole that breaks the rhythm of the sentence, which usually sounds worse than the filler did.
Ignore is right when timing must not move — when the audio is cut to video, or a music bed underneath would drift out of place if the voice got shorter.
