I've been using VSDC Free Video Editor for a year or more and frankly don't find it very intuitive. However, I have studied as much as I can find online and do pretty well editing videos for an oral history project I'm doing. I recently tried to master the zoom function following some instructional videos on YouTube. I got the zoom to work, but as the picture zooms in the audio becomes garbled and the zoom is very jerky. Anyone have any similar experience or thoughts on a fix. Thanks.
