Nesses codecs, toda a informa\u00e7\u00e3o relevante de compress\u00e3o fica armazenada em cada quadro (<em>frame<\/em>), em vez de em quadros-chave (<em>keyframes<\/em>) posicionados a cada 30 ou 60 quadros.<\/p>\n<p>Esses arquivos com resolu\u00e7\u00e3o menor costumam ser chamados de &#8216;proxies&#8217; &#8211; termo usado para definir qualquer coisa que sirva como intermedi\u00e1ria, normalmente por um per\u00edodo determinado de tempo, para se chegar a algum fim. No nosso caso, usamos v\u00eddeos em resolu\u00e7\u00e3o pr\u00f3xima \u00e0 SD (ou <a href=\"https:\/\/en.wikipedia.org\/wiki\/Standard-definition_television\" target=\"_blank\">standard definition<\/a>) como intermedi\u00e1rios para deixar o sistema mais leve ao fazer os cortes, que constituem a parte pesada do processo de edi\u00e7\u00e3o. Ao final do projeto, voltamos a apontar para os arquivos em alta resolu\u00e7\u00e3o para tratamento de cor e render final.<\/p>\n<p>O <strong>Velvet Revolver<\/strong> busca automatizar o processo de cria\u00e7\u00e3o dos proxies para que voc\u00ea n\u00e3o tenha de se preocupar com toda a parte t\u00e9cnica. E uma vez que voc\u00ea n\u00e3o vai querer entrar em um projeto complexo de edi\u00e7\u00e3o usando v\u00eddeos em h264, ou com taxa de quadros (FPS) diferentes devido \u00e0 <a href=\"\/pt\/blender\/#blender_limitations\">limita\u00e7\u00e3o do Blender<\/a> em mistur\u00e1-los, o complemento tamb\u00e9m possibilita criar c\u00f3pias do seu material original nos codecs ProRes422 ou MJPEG, que s\u00e3o os melhores formatos para edi\u00e7\u00e3o de v\u00eddeo. A gera\u00e7\u00e3o dos proxies e das c\u00f3pias em alta resolu\u00e7\u00e3o pode ser feita junta ou em separado. Como atalhos, o Velvet Revolver usa o <strong>Ctrl+Shift+P<\/strong> para apontar a linha do tempo para os v\u00eddeos em alta resolu\u00e7\u00e3o e <strong>Ctrl+Alt+P<\/strong> para apont\u00e1-la aos arquivos em baixa resolu\u00e7\u00e3o.<\/p>\n<p>Assim, a descri\u00e7\u00e3o de um processo t\u00edpico de edi\u00e7\u00e3o com proxies seria: capturar os v\u00eddeos; copi\u00e1-los para o computador; usar o Velvet Revolver para fazer o processo de cria\u00e7\u00e3o de proxies e, se quiser, das c\u00f3pias em ProRes ou MJPEG; deixar a m\u00e1quina processando enquanto voc\u00ea vai fazer outra coisa como almo\u00e7ar, descansar ou namorar; usar os proxies para fazer os cortes e estabelecer a linha narrativa; fazer v\u00e1rios renders intermedi\u00e1rios ainda em resolu\u00e7\u00e3o SD para checar como o v\u00eddeo est\u00e1 ficando. Com os cortes prontos e em vers\u00e3o final, o processo \u00e9: usar o Velvet Revolver para apontar o projeto para os v\u00eddeos em alta resolu\u00e7\u00e3o (a 720p, 1080p ou superior); fazer o tratamento de cores e fazer o render final.<\/p>\n<p>A tabela abaixo, fruto de uma <a href=\"http:\/\/florestavermelha.org\/2013\/02\/28\/blender-novas-funcoes-o-video-explicativo\/\" target=\"_blank\">pesquisa feita ao in\u00edcio de 2013<\/a> como parte do <a href=\"http:\/\/florestavermelha.org\/2013\/11\/25\/os-programas-usados-no-floresta-vermelha-quais-como-e-quando\/\" target=\"_blank\">workflow de trabalho<\/a> do projeto <a href=\"http:\/\/florestavermelha.org\" target=\"_blank\">Floresta Vermelha<\/a>, evidencia o porqu\u00ea \u00e9 interessante usar proxies na edi\u00e7\u00e3o.<\/p>\n<p><a href=\"https:\/\/i0.wp.com\/blendervelvets.org\/wp-content\/uploads\/2014\/10\/blender_render_tests2.png\"><img loading=\"lazy\" src=\"https:\/\/i0.wp.com\/blendervelvets.org\/wp-content\/uploads\/2014\/10\/blender_render_tests2.png?resize=628%2C242\" alt=\"blender_render_tests2\" width=\"628\" height=\"242\" class=\"aligncenter size-full wp-image-798\" srcset=\"https:\/\/i0.wp.com\/blendervelvets.org\/wp-content\/uploads\/2014\/10\/blender_render_tests2.png?w=628 628w, https:\/\/i0.wp.com\/blendervelvets.org\/wp-content\/uploads\/2014\/10\/blender_render_tests2.png?resize=300%2C115 300w\" sizes=\"(max-width: 628px) 100vw, 628px\" data-recalc-dims=\"1\" \/><\/a><\/p>\n<p>Um projeto que use v\u00eddeos de proxy em codec MJPEG e \u00e1udio em PCM gerar\u00e1 esses renders intermedi\u00e1rios quase 4x mais r\u00e1pido do que o mesmo projeto em alta resolu\u00e7\u00e3o.
