so how do we fix this? Seems the setting to switch the video rendering tool of is not there anymore, i need to caption 20k images and for two hours i have this theater now...
I doubt that videos are crashing Photo Mechanic. Photo Mechanic runs a sub-process to render videos. If that sub-process were to crash, it wouldn't take Photo Mechanic down.
I expect that you have one or more images that are causing one of the libraries that Photo Mechanic uses to decode images. If they're JPEGs or RAWs, then the crash is likely due to malformed JPEG data.
What format are the images?
