Okay, so I recorded some gameplay on my Wii U and some audio separately. The files on there own are fine, but after bringing them into the Roxio editing software and cutting out some bits, it picks a particular second and the video will black out, the audio will continue playing, and the program will crash. If I export the file, the program will stop exporting at the same particular second.
I tried re-doing it all, only for it to pause around a very similar minute and second, and I've also tried restarting the program and my computer. Could anyone lend a hand? If I need to provide some kind of crash report or computer info, please also tell me how to retrieve that for you.
