P.S. I'm a guy but I can see how the name confuses people. :) As for my Computer Knowledge, I have a degree in computer science and before that was a Computer Technician for years. Like you said my Mac platform is probably off-the-mark, but that does not mean a Mac is necessary for what he is doing"
That was no disrespect to you "TheMacUser" at all you sound like you have great knowledge and experience in Video Editing and the such...
My Best Friend is a Independent Film maker. I have watched him and his team do all kinds of stuff and they had to make due with what they had, rent barrow what ever it was because of his Budget. In University he used a Mac for all his editing and the such and he loved it. But once he was done University his budget was not big enough for everything so he had to make due with what he had and could get on his budget, I think that is what this guy is trying to do, So for a long time my friend and his team had to use a PC and Adobe for all his Video editing, because that was what he had and could afford at the time.
Anyway like I said I have only 1 Mac and its old, I barely use it except for some basic editing that does not need a lot of power and done fast(Very Rarely), My Knowledge is probably off when it comes to Mac's but $1000 for a macbook used for video editing seemed a bit cheap "price wise"("Even though they are Video editing ready right out of the box)". Mac's are usually very expensive, All I meant was spend 1000 now on a cheap one and 6 months - year down the road you may need to buy a whole new one due to your needs wanting more faster or depending how your your interest in Video and editing comes along.
That is Why I suggested a normal Windows PC because most people have access to them, cheaper if a upgrade is needed and allows for upgrades where some Macs do not really leave room if you are buying the cheapest one. Plus most people know how to use a PC better and way more experience, unless you are going pro have the budget then go grab the Mac but IMO I think the money could be spent better on Camera and other accessories and software needed.
Use a PC and some editing software to see if you even like what you are doing and if this will become a hobby or just dwindle off into nothing once the project is done. In that case Money Could be Wasted on a Mac.
Like said the Camera with HD is one of the most important things with a good audio Mic at that, then comes the computer and editing software. You probably have access to a Windows PC. Do your homework download some trials of what you decide to use. Try them out on some short video's. Like I said in today's day and internet age you can get Video how-to's do anything step by step with any popular Editing Software either way you are gonna have to do your homework. Fast and easy with a Google search. You are going to need research and some sort of training anyway.
But then again a Mac could be your best bet, that will be your choice after you weigh all the factors, & research you do.
There are a lot of enthusiasts and pro's that have very nice and the best of everything Mac's for editing and Pro Camera's which for this project it seems like you do not really need. A enthusiast or Pro sometimes seem to think the normal person need all this stuff also, in most cases you do not. Work with what you have.
Some actually a lot of Enthusiasts and pro's in there field "no dis-respect" including myself, but in any Enthus-hobbyist and job the best is always suggested when it usually not always needed, when you work with the best, you tend to think that is the only option, that is in any field so watch out for people saying buy overpriced stuff or the newest out, which in most cases will not be the best for you.
