AVItem setProxy() method
a pp .p r o j e c t .i te m (i nd e x) .s et Pro x y( fil e)
Description
Sets a file as the proxy of this AVItem. Loads the specified file into a new FileSource object, sets this as the value
of the attribute, and sets
p r o x y S o u r c e
instead using the user preferences. If the file has an unlabeled alpha channel, and the user preference says to
ask the user what to do, the method estimates the alpha interpretation, rather than asking the user.
This differs from setting a FootageItem's main source, but both actions are performed as in the user interface.
