I have no idea what is wrong. I have been working on my movie project for 3 days (naturally a long time since I have school during the daytime) And I stayed up all night on the last night just to finish editing it. I left all the saving for the early morning before the submission, but when the morning came I could not save it. It only said "saving movie... step 1 of 2... 0%" even after 40 minutes have passed, no change. Just 0%. So I (winged) it copying the actual file to my flashdrive to pass it to my teacher. I know it would not play, but I gave him the flasdrive just for the sake of him knowing I did the project but I had last minute technical difficulties.

Tonight, I tried pushing my hopes up by trying to save it again, this time with the help of google and forums. I followed steps yet nothing happened. Still the same dissapointment of words for a thousand tries. 

Just then (2hours later) When I've decided to split my video and removed 3 minutes (my video is a total of 7 minutes) temporarily, It saved. 4 minutes of the video saved. Now I've grown more hope and edited the 3 minutes back in, but then it won't save again. I've tried dfferent options and techniques just to save it but after 3 hours i had no shed of luck again. 

Now, I've shot the video with an iPhone 4, I've added in two pictures from the internet, a 7 second video clip from Messenger, and more or less 10 pictures from picsart. Would it still be an error if they all came from the same application/gadget? There are no small yellow triangles or any error that are notifying me, my video card is updated and I sure as **** have space (btw I also tried saving it in an external storage- didnt work) what the **** is wrong then? If it had an error shouldn't it notify me, not make me guess what is wrong?

I've used wmm before, I even edited a near 30 minute hd video and it saved smoothly. What is wrong this time? Please I need answers. My grades (and my group mates) are in line for this. I need to pass this asap. And by asap I mean tomorrow (please.) Thank you in advance to anyone who would answer.
