Tom W., if you really want to know...
Another FCP forum, LACPUG, is suffering from disuse and trolls, and I'm one of the old loyalists sort-of policing it. See for example: http://www.lafcpug.org/phorum/read.php?1,288204,288207 .
The latest troll (or fool) there is this Ballower: http://www.lafcpug.org/phorum/read.php?1,261516,288219#msg-288219 .
Ballower, posting in LACPUG's FCP7 forum, referenced the thread we're here in. When I clicked on Ballower's link all I saw at first was the original question and your original answer, like so:
If those three lines are the Question and those other three lines are the Answer, marked "Solved", then Apple Communities are in a bad way too. I was struck by the sentence:
No video editing application can open a video file.
as a pretty amazing thing for a Level 10 member to say.
I eventually pressed the "View answer in context" button and saw that there was more discussed, but the poor format which had hidden all that and sloppily credited the wrong post as the Answer, led me to reply to that one sentence.
I have learned from this discussion that Apple shifted its concept of "open a video file" sometime between 2010 and 2011, for its video editing program, not for its video player/converter. I don't know if Apple was following other softwares in doing this, or trying to lead them. I find the shift ridiculous, and not so easy to swallow as you do.
