site_archiver@lists.apple.com Delivered-To: pro-apps-dev@lists.apple.com The specific error you’re seeing: -12792, is a timeout error. This usually occurs when writing out a frame takes an excessively long time (longer than 2 minutes). Note that this doesn’t mean that rendering the frame takes longer than 2 minutes, just that writing it to disk does. Things that could cause this include the system running low on memory and spending a lot of time swapping, having a really slow disk, and other applications that are also writing to it at the same time, etc. If the disk is mounted over the network and has lost its network connection, that would also do it. So I don’t think that part of your problem has to do with your FxPlug. The second part is saying that your plug-in wasn’t found by PlugInKit, so it could not load it. Was the error in the console printed at the same time as the export error occurred? I ask because the apps don’t generally try to load plug-ins at any time other than startup, so I would have expected to see that message when the application was launched rather than during an export.

I am wondering if anyone here has a list of the Motion Critical Alert error numbers and corresponding message. With my FxPlug, after several hours of rendering it can fail with this message from Motion:

Export Failed The operation could not be completed because an error occurred while exporting (error -12792)

I suspect that this will merely correspond to the following in the Console, but I could always hope that the error code points to some additional/different clue, to what is otherwise probably going to be a very tough bug to track down.
