I have been using the software and all has been fine to start I have uploaded a few videos on you tube at Muffalo Gaming check it out. A problem has occurred in the editing software that whenever I put in a file it goes Black and White and so does text effect.I opened up the clips elsewhere and It was fine so it is not the video clips either .I have tried repair and uninstall but nothing is working what should I do I need help and advice ?
