TRANSITION: Research into Audio & Colour Grading

After editing the test shoot, I realised how much I had forgotten or didn't even know about editing over the last 4 months. I knew audio was never my strong point, but for this unit I want the audio to be perfect so I did some research into it, along with research on colour grading. If I learn it now, this will save time during the edit. I picked out specific points to learn depending on what I'll need to use during the edit. 

Audio effects
DeNoiser - gets rid of background noise without using Adobe Audition.

Equaliser - if the audio is base-y, or high frequency / high pitched audio. Go on effect settings and press 'Edit' and it shows a visual example of what the audio is looking like, e.g. in a graph. Can change the effect while watching the clip with the visual audio graph. Bring the base down and the audio can sound like someones talking on a phone.

Reverb - gives an echo to the audio - can change the different types of echo, e.g. small room, church etc. 

Audio should be at -3 and not peaking. 

Get all audio louder - right click - audio gain - normalise peaks to -3 

Compressor (dynamics effect) - gives fullness to the audio. Compress the peaks, and help the quieter audio become louder. Effect settings - 'Edit' - compressor column - 'Ratio' no more than 4.50. 'Makeup' at 12.

Mastering - 'Edit' - subtle clarity (however gives reverb). 

Treble - 7db 

Save these effects as a preset - select audio clip which has effects on - effect settings, group select all effects - right click 'Save preset' - type 'Scale' - rename - adds to effects column.

Reducing noise in audio clips - Effects > Noise Reduction/Restoration > Capture Noise Print.
In the Editor panel, select the range from which you want to remove noise.
Choose Effects > Noise Reduction/Restoration > Noise Reduction



Colour grading
Colour matching effect - Lumetri colour panel (effects control) - 'Colour wheels & match' tab - 'Comparison view' - disable face detection if no faces in shot - 'Apply match'.

Mask tool - draws free-form marks and shape masks. 'Basic colour correction' colour tools (inverse mask selection) - excludes the masked area from colour corrections applied to the rest of the clip. You can add multiple shape masks with different colour adjustments applied to different areas of a clip. 

Save colour presets - Lumetri colour pop-up menu - 'Save Preset' - rename - description - 'Apply'. 

Add a key - Eyedroppers to select / add / exclude target ranges - select eyedropper - move over the colour range you want - click to apply the range - hold down Cmd / Ctrl modifier key while hovering over the programme monitor - set eyedropper to 5x5 pixel selection - select colour range from the colour range presets (C/M/Y/R/G/B).
