Video Editing

Pacing

cutting audio up to make the audio breathe is the video editor's equivalent of punctuation
slowing down/speeding up clips to make it less/more dynamic
use dynamic zoom to add more movement

Transitions

less is more, if a straight cut works

Version Control

duplicate the timeline before making major changes

Edits

backtimed: specify where the shots ends by only adding an out
replace: used for syncing audio to a specific point in the clip (uses position of the timeline and playhead for the edits)

Audio

Any audio levels above 0 dBFS clip and will sound distorted, so you must always keep audio levels below 0 dBFS. There's some guidelines, but ultimately use your ears.

dialog: target -12 dBFS
sfx: between -10 and -30 dBFS
music: between -20 and -30 dBFS (usually sounds louder due to a narrow dynamic range)

Color

Color correction is not something you can do by learning the controls of the color corrector, and it’s not something you can do well just using the scopes. It’s a highly creative skill.

Audio Post-Production

soundtrack spotting: sit down with director and discuss what soundtrack elements are good
dialogue editing: remove clicks, pops, uhms, reducing noise, replacing and potentially recording the audio, volume balancing
sound design & effects: natural sounds, ambience, hard sound effects (usually synced with video), Foley sounds (sounds of actors interacting with environment, such as movement of clothing)
music editing: diegetic music (music heard by characters), non-diegetic music (music only heard for the atmosphere)
"audio correction": volume controls, panning, dynamic controls and EQ
