I have an MP4 video file, I play it on windows media player or VLC plyer and it is as recorded, no problems. If I then drag it onto the timeline of Movie Studio Platinum 13 (latest build) the audio has clicks and pops that weren't there before (if rendered the clicks and pops remain). This doesn't happen with other file types. I have tried increasing playback buffer times as suggested by the live chat system, but this had no effect on the problem.
Can anyone suggest anything? Thanks
