Hi mate - yes I remember you, cause your vid was very emotional for me, very touching the way you put together the real film footage and such...you have talent mate, I can't wait to see more of it.
From the MovieMaker course (link to full course in my OP, under VID TECH HELP bar...
If you have been able to render before, my guess is that #2 is your problem...I used to run into this ALOT. That hidden, un-clipped footage in MM is a killer. So if you have long clips where only a fraction appears on your timeline, split the clip down to only what you are using. If that still doesn't work, you'll have to do what Lewis and I have resorted to a few times, which is divide your vid in manageable pieces, render it in, say 3 sections, and then with those completed .wmv files, put them together and make one big movie. Re-rendering hurts quality a bit, but is sometimes your only option. MM has a hard time with too much info from raw .avi files...that seems to be the heart of the issue.
Also, unless you have a top notch machine, make sure you aren't doing anything else resource intensive on the computer while rendering.
If these don't work, we'll go to plan B...and while you are working on it, I'll figure out what plan B is
cheers mate, let us know if it works!
