I've just been piecing together the clips I shot at a Steam weekend the total time being about 33 mins. I left the PC processing the file as an HD Movie and came back 90 minutes later to find it had failed saying it couldn't find some files, all the clips were loaded so i don't see that as a problem. Is there a limit to the size of file it can handle? This is the longest I have done with it. I could split it into two parts I guess but would prefer just one. Any suggestions welcomed.
