Looking for some help with an error message when exporting master file. I'm stuck and would even pay to get this sorted out!

Question

Hey guys, I'm really in a bind here and need some urgent help tonite. I would even be willing to pay for some actual help and not some vague information that i may not be able to understand if we could do something via skype or some other way that would be much quicker than a message board. Of course I have to have the project done by tomorow . so I'm new to fcpx, but have succesfully exported 2 other projects. I've also ran into this predicament before (error message not allowing me complete export) and have been able to solve that by converting the files i imported off my camera (canon g20) to a different file type (prores).
so where I'm at now: i have a 13 min short, all shot on my canon g20, imported and converted to prores422 with the brorsoft video converter with all the shots in a single event in fcpx. i'm using fcpx version 10.0.08. I have one main video track in my timeline that is completely full of very fast edits. (all quick 2-5 second clips, sped up shots in 2x, 4x, or 8x, tons of transitions, titles, and a little fx. theres 2 audio tracks, one is narration/speech and the other is an ongoing music track that constantly ducks everytime the subject speaks (tons of ducks/edits). Have you seen mtv cribs? Well i filmed an EXACT replica. So If you've seen one of those episodes, its literally the same exact same thing. I have all of my work completed, everything has been fully rendered, and i have it exactly as I want it.
I'm including all this information in case it may help. my successful projects ive exported in the past were rather simple, and this one is very complex and full of edits. here is what it looks like in the timeline:
Ive tried exporting the master file using almost all the different ways with no luck. My primary objective is to get it on youtube by any means by tommorow for a showing to a potential buyer (long story) and so I've been told using the h.264 is the best format for that. This, along with the other methods give me the same error message:
It think it gives this error message when i reach 24% everytime during export.
So first of all, what is that error message? Do i need to be concerned about the specifics of it, or is there something major that I'm missing? Like i said, i dont care how, but I need to get this video up on youtube tonite for an important viewing tomorrow. Conceptually, I think if i can figure this one out I shouldnt have any more trouble in the future doing something so basic, yet critical, such as exporting my 40+ hours of work for someone to see.
anyway, I apologize in advance for my lack of knowledge with this software, and for my extremely long winded question which will probably have the opposite effect for me as most wont want to take the time to read all this, BUT i figured if i was as thorough as possible it might help actually getting a concrete answer, instead of a "read the manual, exporting is on page 37." or "use the share button on the right of the timeline then just click export master file and it will work everytime."
Cheers everybody, and thank you. Like i said if someone is up, and willing to talk via skype, phone, messanger or any other method that works for you I would be totally down and will compensate you generously for your time. thanks again.

Answer 1

boom! that advice was correct and worked. i was able to export the full project as a quicktime movie and it can be uploaded to youtube.
NOTE, theres is definately quite a few noticeable audio glitches/lags/pops that werent there before doing this. I believe, and will test to make sure, that having a project such as this one needs to render before exporting. I'm not sure if the advice requires the project to be unrendered before exporting for a specific reason, because if it will export fine after rendering the project that's the way to go. like i said the edited version i have in my timeline plays back perfectly but this exported version has quite a few noticeable audio glitches (a few video glitches too). I'm going to retry doing the first few steps of your advice, but then at the end render, then export and compare the results...
OK, so this leads to a big question, Is this something that is standard for everyone when trying to export? If its not, what causes this error?
is there any way of preemptively avoiding it in future projects?
thanks again, and hopefully this information will help others as exporting seem to be one of the biggest problems in fcpx. any word on a new patch or firmware update?
