Hello,

I am trying to edit a movie out of .mts files.  MM 2012 can apparently edit the files and can save them as .wmv files.  Also, I can view the files using Windows Media Player, no problem.

However, if I save any file larger than about 5000kb using the "Youtube" setting (ie as an .mp4) I get a corrupt file that I can't open, that G-Spot doesn't recognise, and which MediaInfo doesn't recognise. 

Any solutions?

Thanks
