Hello everyone and excuse my bad english. In the last few days i've experienced a problem with sony vegas pro 15. When i open a mp4 file, it opens the video, but the video comes with 7 panels of the audio. It sounds robotic and glitched and when i try to delete 1 panel of the mp3, it deletes the whole thing. I've tried to mute some of the audio and it still sounded robotic. At first i though its because of my new headset, (razer kraken) because it has surround sounds and everything... But i've checked tried a few more things and the problem could'nt get fixed. Now i've uninstalled my sony 15, and installed the 13 version. It cant even open the file it displays this error: "Warning: An error occurred while opening one or more files. The file could not be opened. Make sure the file exists and that you have access to the file/folder. Thats everything i could tell about the problem, i will be really happy if you guys try to help me fix it. Everyone have a nice day!
