I made a simple video and made two fragments (two seperate .mp3 files) speed up (time > fast > forward > 2x). When I exported the video, the fragments didnt speed up at all, they stayed 1x.

I exported the video with: HD 1080p 60 fps (1920 x 1080)
I heard that the issue wasn't happening in 30fps but I'm not sure whether that is true (the video takes a long time to export, so I haven't got round to testing that)

I hope that this will be fixed soon, my videos rely on the time feature a lot...
Thanks, MineMoebsie
