# Ultra quick'n'hacky AE camera animation importer for Houdini.
# Create a new shelf, create a new tool, paste this into the script box.
#
# In AE, select the Orientation and/or Position keyframes, and Ctrl/Cmd-C them to the clipboard
# Open a new text file (Notepad or Textedit) and paste the clipboard contents in. There's your keyframes.
# Save the text file somewhere and amend the filename line below to suit
# In Houdini, create a camera (it's up to you to set the same zoom / aperture as the AE one).
# ... and run this script (well, press the shelf button you stuck this on)
