Blender Video Sequence Editor is a simple tool to edit your sequence animation that made with Blender, you don't need to using another video editor like adobe project, sony vegas, etc. Because Blender VSE is more than enough for editing. This feature can use for editing non animation movie. I've made some short movie using Blender Video Sequence Editor.
The problem when using Blender VSE as editor movie film is the video and audio strip not sync when imported into Blender. If you play the video, they are sync. But when you import to Blender, they are not sync. Finally, i know the answer of this problem.
