Is there any other way I can do this? There's nothing apparently wrong with my video file and in fact use it fine (though slow) for editing without the Proxy file. I can even create my own Proxy file using another program, but don't know how to let X5 know it is there and to use it.
What are my options to get SmartProxy to work? Why would it simply stop processing and not create the Proxy file? It is too far into my project to break the video up into smaller chunks, though that would only be a guess because I don't know why SmartProxy should stop processing
