hi I have noticed that when IPI studio is working of the PC enters to a mode that uses the screensaver, or hibernate, or turns off the video the Rendering hook crashes, it's not really serious but maybe to trap that exception or to reset the video on resume would avoid that problem

however it's not serious since IPI studio records ever frame it decodes.

Thank you

Sorry for that bug. Will be fixed sometime in the future. It's hard to fix quickly for reasons too complex to explain here.

And yes, iPi Studio autosaves processed frames if it has where to autosave (if you saved your project to a file).
