Timecode audio recorded between -20 to -10 dB. (Be sure to properly pad the timecode level!)
Record at a minimum of 128kbps @ 44.1/48kHz CBR (Constant Bit Rate)
CBR (Constant Bit Rate) only! Do NOT use VBR (Variable Bit Rate)
ALC (Automatic Level Control) should be OFF – ALC corrupts both the dialog and timecode recording.
As a contingency – and if circumstances allow – you can include an audible ‘slate’ of the timecode for reference. Slate the timecode count clearly and pedantically into a mic so it is included within the recording. Clearly slate and identify the hour, minute and several seconds.
…we are at hour seven… three minutes… and twenty-one, twenty-two, twenty-three…
What doesn't work:
…we’re at ten… and seventeen… now!
NOTE: You will have to re-slate at each break in the timecode.
