There seems to be a disconnect on the import of FCP XML files. The file begins to import on command, the log initiates and notes the activity, then when the file is displayed on the timeline as clips, the popup window asks: "are you sure you want to cancel your media import" Clicking no just refreshes the message. No media import occurs. There is no way to relink the media because M100 won't respect the codec from FCP. This makes the feature absolutely useless.
Is there a way to fool M100 into seeing the original files from FCP. I hate all the waste when the two systems don't play nice....
the XML import usually transfers over the video and audio material from FCP. Not sure why this is not working for you. I would guess that there is some sort of bug, or something that is not working in your timeline.
I would suggest doing a quick test with a simple FCP timeline, just a couple of clips, to see if there is something wrong with your system in general. If this works, you probably should send the XML to Media100 support with an explanation of what the issue is. If they know about problems, they are usually very good about fixing them.
