My audio is the right speed, but my video is way too fast. As in, the clip is 44 seconds long with it sould be 14 minuets. I am using a less powerful computer, but I don't know how to fix this. I am using Vegas Movie studio version 16.0.
It's likely your video is using a variable frame rate compression system.
To confirm this, open a clip of your original video in the free download MediaInfo. In MediaInfo, set View to Text and then copy the report it generates and paste it to this forum. Once we see the video's specs, we'll better be able to advise you.
