Audio does not fit the video
After exporting my fully edited video it's werid because video is like in slow motion but then audio goes in real time. in a couple of seconds the audio is much further than the video. I have this issue with videos longer than 10 minutes in normal preset for YouTube, (1280x720 and i have to keep my aspect ratio by expanding due to that my sreen is not in 16:9 i keep 60fps as in my raw recordings, aspect ratio is :square pixels 1.0 , profile :main, level:4.0 ,encoding: Variable Bitrate, 1 pass target bitrate and max bitrate are 10 and 15 mbps, audio ACC 192 kbps) or in all videos wth resolution higher than this.I asked my friend using hitfilm to export movie from camera and he has the same problem I'm really new to video editing and I'd appreciate all help that i could get. If anyone knows how to fix it please help.
