My fanvid won't save to my pc - it saves about half then stops, any ideas??? Thanks!!!

lol its been 2 years but still i will answer.
Something exactly like that happened to me as well, what i did was buscar for the clip in the project that was creating the problem, for finding that, i saved each clip individually. [ Copy that clip< open new project< paste it< save into my computer ] in my case, the first few clips saved without any problem, then at the middle part, found a clip that was not saving -[thats the clip causing the trouble.] i also found one o two más similar clips. Then open your project, just división, split the clips causing trouble into two o más parts, then try saving it. This worked for me. And if it still doesn't save, borrar some frames(a screencap/ a very small part, less than 1 sec) of that clip and try saving it and even if it doesn't work then borrar that particular clip and put some other clip.
And also, tu shouldn't mover your clips from that particular folder/place from at where tu imported.
I hope it will work cause it worked in my case. :)
