quicktime中的AppleScript剪辑电影

Question

我想每帧数量而不是秒数剪辑视频文件。 到目前为止，我已经尝试了几个选项，这是迄今为止最成功的一个：

set start_trim to 5 
set end_trim to 6 

tell application "QuickTime Player" 
    activate 
    try 
     set movieFile to (the POSIX path of ("PathToMovieFolder")) & "MyMovie.mov" 
    on error errorMsg number errorNum 
     display alert errorMsg & space & errorNum message ¬ 
      "An error occured trying to find the file " & movieFile & "." & return & ¬ 
      "Check the file path exists, and the file spelling." as warning giving up after 60 
    end try 
    try 
     open movieFile with presenting 
     delay (0.25) 
     present document 1 
     delay (0.25) 
     trim document 1 from start_trim to end_trim 
     display alert errorMsg & space & errorNum message ¬ 
      "An error occured trying to open & play the file " & movieFile & "." & return & ¬ 
      "Check the file path exists, and the set delay time" as warning giving up after 60 
    end try 
end tell 

它所做的是，它它修剪到秒，而不是确切的帧。 关于如何解决这个问题的任何想法？

Answer 1

帧不在QuickTime Player字典中。但是，它位于QuickTime Player 7字典中。如果你需要使用框架，而不是秒修剪，我会建议寻找QuickTime播放器7

的副本，或者，也许你可以做这样的事情：

set FPS to 29.97 
set start_trim to 5 
set end_trim to 7 

set startFrame to start_trim/FPS 
set endFrame to end_trim/FPS 

tell application "QuickTime Player" 
    activate 
    trim document 1 from startFrame to endFrame 
end tell
