Students'are'constantly'haunted'by'many'doubts'during'the' shooting'process.'Am'I'getting'the'shot?'Are'there'breaks'in' continuity?'Is'the'lighting'going'to'hold'up'through'the' inevitable'compression?' ! Did'my'footage'safely'transfer'into'the'P2'store?'Are'there' any'corrupted'shots?'Am'I'sure'I'transferred'all'my'files'off' the'P2?' ! Do'I'really'need'to'digitize'all'this'footage'in'realOtime?'Is'this' tiny'LCD'faithfully'showing'what'I’m'capturing?'

Introduces'a'tapeless/p2Oless'digital'workflow'eliminating'any'dark' spots'in'the'acquisition'process'where'there'is'uncertainty.'' ! By'introducing'the'use'of'powerful'direct'to'disk'recording'and' monitoring'software,'this'project'will'help'students'shoot'better,' smarter,'and'with'more'confidence.' ! This'workflow'has'to'be'applicable'to'any'digital'video'production' whether'HD'or'SD'

  17. DTD'RECORDING'TEST' Experiment'1'

  18. DTD'RECORDING'TEST' Overview' ! Two'HDD’s'were'used'to'test'the'software’s'ability'to'record' faithfully'given'slow'hard'drive'speed'limitations.' ! The'Hitachi'is'meant'to'represent'a'slow'HDD'because'it'is' much'older,'has'slower'access'time,'and'spins'at'a'slower' speed.' ! The'Samsung'is'an'external'HDD'and'is'meant'to'represent'a' modern'faster'HDD'most'commonly'used'today.' ! Both'HDD’s'underwent'the'recording'of'an'HD'stream'from'a' Panasonic'HVX'200A'in'both'a'720p'and'1080i'resolution.'

  23. DTD'RECORDING'TEST' Conclusions' ! Software'will'prioritize'recording'over'smooth'monitoring'and'in'both' 720p'&'1080i'resolutions,'the'HD'video'stream'was'recorded'with'zero' dropped'frames.' ! The'Sony'Vaio'lacked'the'processing'power'to'achieve'recording'and' monitoring'of'the'video'stream'in'realOtime'but'when'the'captured' footage'was'then'taken'to'a'more'powerful'computer,'the'clips'played' back'flawlessly.' ! In'any'event,'faithful'recording'of'the'stream'will'be'guaranteed'even' with'today’s'oldest'laptops'not'to'mention'any'new'laptop'sold'today.'' ! Playback'of'the'stream'while'recording'is'directly'related'to'processing' capabilities'of'the'computer'and'this'processing'power'threshold'is' determined'in'another'experiment.''

This'experiment'was'an'attempt'to'find'the'threshold' processing'power'requirements'that'guarantees'smooth' monitoring'of'the'HD'video'stream'while'recording'to'disk.' ! 7'different'laptops'in'both'platforms'running'Adobe' Onlocation'CS3'&'Cs4'were'used.' ! First'test'was'to'check'if'the'processing'power'of'each'laptop' could'playback'(decode)'a'720p'&'1080i'video'clip.' ! The'second'was'to'verify'smooth'monitoring'while'recording' a'720p'&'1080i'video'stream'to'their'internal'hard'drives.'
