  Trim Comp to Work Area

  Posted by Nick Leigh on May 9, 2014 at 3:39 am

  I have searched google and this forum and found the following code to trim my comp to the work area:

  
videoComp.workAreaDuration = 0.6;
videoComp.ramPreviewTest("",0.33,"");
videoComp.workAreaDuration = settings.compLength;
app.executeCommand(app.findMenuCommandId("Trim Comp to Work Area"));


  I am using AE CS5

  The problem is that I am getting an error every time I run my script. The error states:

  Unable to execute script at line 103. After Effects error:RAM Preview needs 2 or more frames to playback. Line 103 is the ramPreviewTest line.

  Thanks for the help.

  you would commonly see that error if the cti was at the end of the comp work area and tried a ram preview from current time.

  if that’s the case here, then you may need something in the script to either do a ram preview for the whole work area, or move the cti from the last frame of the comp/work area.

  Ok so I tried your solution and set the current time to 0 and I was still getting the same error. Here is what I am doing:

  
videoComp.time = 0;
videoComp.workAreaDuration = 1;
videoComp.ramPreviewTest("",0.33,"");
videoComp.workAreaDuration = settings.compLength;
app.executeCommand(app.findMenuCommandId("Trim Comp to Work Area"));


  Is there a way to simply set the comp duration of length?
