So the last few videos I have made I have been having issues with the finished product. The video has been coming out where it seems to get out sync within the last few minutes of each other. The sound and footage. Basically what happens is I have been using the speed up effect and it goes a little bit longer than it should be from where I have originally edited it in the video and then towards the end of the video it will somewhat repeat some part of the footage and gets back how it should be. I have noticed this in the last few I have posted as well and I have changed nothing in my settings and didn't know if this might of have something to do with the recent updates in the last few weeks.
As you can see in this video it is really bad out of sync with each other about the 28:30 mark and I can't figure out why as the other videos I have made have no had the issues at all.
