ok my orignal raw video was 20 seconds and after i rendered it in vlab it was 14 seconds. what went wrong because i had sound and when i went to add the sound to the render video in movie maker , it didnt match up. Does it has something to do with framerates per second and/or the pixels or something.please help me

Obviously the framerate will affect the total length of the video, yes. If you have 100 total frames, whether you play them back at 1 frame per second or 30 frames per second will significantly impact the final length.
The scan method can also affect the final length, so make sure you know what the framerate of the original footage is, determine for certain whether it is progressive or interlaced, and use those settings when you create your VisionLab project. The easiest way to get this info is probably to start a VisionLab project using the "Select video clip" option, and it will automatically set up the project to match the footage. Then, when the Project Settings window appears, make a note of those settings for future reference.
