Great advice, Adrienne! I think every one of us yearns for the chance to shoot on film and should I ever get it I'm going to make use of every tip I can get.
A few other ideas: take a break for a few weeks, work on something else, and come back with fresh eyes. You may see it in a completely different way. That happens often with any kind of project.
Also, has anyone else seen it? Consider showing it to another editor who has not been involved in the project at all. You're almost guaranteed to get a dozen light bulb moments when that person says "have you thought about trying..."
But bottom line, I agree with what everyone else here has said: under no circumstances leave the project unfinished. That's the only scenario here in which you truly fail.
Good luck, and be sure to let us know how it goes!
Another vote for Videocopilot, but also, see if your local community college has a class. Nothing beats learning from an actual human, and classes at community colleges are usually cheap.
YouTube's automated system will almost certainly catch it right away and flag it. The system will tell you a claim has been made by the copyright holder and depending on how that copyright holder has things set up, nothing at all might happen, ads may start being shown over your video, or your video may be taken down altogether.
All three things have happen to me almost every time I upload a video even though I never use unlicensed music, because even stock music is in YouTube's automated system. In my case, I have to dispute the claim, provide licensing information, and wait for YouTube to work out the dispute with the copyright holder.
In one case, YouTube had removed the video and we already had over 100,000 hits - by the time it got worked out we'd lost momentum and couldn't regain it. I've learned the way around this is to upload as a private link, let the system flag it, dispute the claim, resolve it, then release the video.
But having said all that, Matt's point is paramount: find or compose original music. Quality stock music doesn't have to cost a lot. Please try a site like audiojungle.net or pond5.com or spend an afternoon with Garageband.
Brooks is recommending a really great book. Watch this video to hear the authors address the very issue you're asking about. They talk about an entire feature film that was shot inside Disneyworld - and got released. Check it out: https://www.youtube.com/watch?v=64WGwD6VIhI&index=1&list=PLez8jOvskc-Maf...
Totally agree with the above. I'd add - often, when I've done a one-take, I'm not doing a locked off shot. In fact, I'm more often doing something really elaborate, in which case storyboards are essential. Better yet, doing rehearsals with stand-ins and someone's phone camera at a very early stage is a great tool. You can show your best take to the performers and crew, too so everyone's on the same page.
