AppleScripting QuickTime Pro 7 para exportar arquivos .png

0

Como posso usar o AppleScript para salvar arquivos .png no início e no final dos arquivos .mp4 com o QuickTime? Isso é algo que estou fazendo muito e seria bom automatizá-lo. Tenho alguma experiência em scripts, mas não muito.

Estou usando o QuickTime Pro 7 versão 7.6.6. Estou usando o comando export para obter quadros estáticos do mesmo tamanho do meu arquivo de vídeo.

(* INSTRUCTIONS
This droplet is designed to process one or more files, or folders containing files, whose icons are dragged onto the droplet icon.
The droplet processes recursively, and will examine the contents of every dragged-on folder, and every sub-folder within those folders, to find and process any files who kind matches the indicated types.
You can set the droplet to process only files of a specific type, such as images, by adding the appropriate data types, name extensions, and type IDs to the values of the properties listed at the top of this script.
Place your script code for processing the found files, within the process_file() sub-routine at the bottom of this script.

Qual versão do Quicktime? Estou assumindo o 7.x desde que você disse "pro" no título, mas esclareça. Além disso, você está realmente usando o método Arquivo> Exportar, está fazendo uma captura de tela (Command-Option-4) ou está editando> Copiar e colando na Visualização ou em um editor de imagens?
Tubedogg
Eu incluí meu código na postagem. Estou tentando evitar qualquer interação que não seja soltar o arquivo na gota. Acho que estou perto de onde preciso estar, mas, neste momento, ele ainda não está salvando os arquivos png e não sei por que.

Esse script agora funciona e salva o início e o fim de um arquivo .mp4 como .png, com as palavras início e fim anexadas ao nome do arquivo.

Obrigado Vic. Eu estava obtendo quadros de 1 segundo desde o início e o fim, então é definida a posição em segundos para 0 e isso me deu os quadros inicial e final. Eu realmente aprecio sua ajuda. Eu atualizei o script na pergunta para refletir as alterações. Estou tentando cada vez mais o script da apple e seus scripts me ajudaram tremendamente a entender melhor enquanto eu trabalhava nisso. Obrigado novamente.

O Applescript que você está usando para o Quicktime está incorreto e você está solicitando que ele execute comandos provenientes das adições padrão. Eu caminho para

O QuickTime não entenderá isso e falhará. Similarmente:

set frameOne of this_item to track (beginning)
set frameEnd of this_item to track (end)

QT não saberá o início e final são

Você deve ler o dicionário do Quicktime 7 para entender sua sintaxe.

No Editor de scripts, vá para o menu Janela-> Biblioteca

Isso exibirá a janela Biblioteca de dicionário de aplicativos.

Duvido que o QT7 esteja listado, então vá ao localizador e localize o QT7. Normalmente, está na pasta / Aplicativos / Utilitários .

Arraste-o para a janela Biblioteca de dicionário de aplicativos.

Em seguida, clique duas vezes nele.

Um dicionário será aberto. Leia-o para entender o que o QT7 pode entender.

Agora o script.

Não toquei em nenhum de vocês.

O que mudei é o conteúdo do manipulador process_file () . E adicione algum Objective-C para simplificar a obtenção do caminho e do nome do arquivo.

Não se preocupe muito com o material Objective -c. Você ainda pode usar o Applescript convencional que você entende se quiser substituí-lo.

As partes importantes são:

Definir a posição da cabeça de reprodução e exportar o filme. Como estamos usando o BMP, ele exportará apenas o quadro atual.

Observe que eu defino o início como 0 e o final com a duração total do filme - 20.

Pelo que entendi, as medidas estão em milissegundos. Portanto, ter -20 no final não deve fazer muita diferença para o que você captura. Mas faço isso porque um dos meus vídeos de teste teve um problema ao obter o último quadro durante toda a duração. Ocorreu um erro ao dizer quadro inválido. Alterá-lo para um pouco antes de resolver o problema.

Eu também uso um pouco de linha de comando para converter o bmp em um png.

Novamente, para simplificar as coisas (pelo menos para mim), você pode usar seu próprio método aqui, se quiser.

use scripting additions
use framework "Foundation"

Também incorporei esse script porque estou tentando entender os scripts. Por alguma razão, esse script é duas vezes mais lento que o abaixo. Isso ocorre devido às adições de script ou ao objetivo c chamado? Fora isso, funcionou bem e fez o que eu estava tentando fazer. É apreciado.
