When done rendering a 15 sec vid, it is only 3 sec vid h e l p

[David Mccormick]

By any chance, do you have loop region checked? This image shows the loop region on the timeline (the area in the two yellow triangles): https://www.sonycreativesoftware.com/support/files/LoopRegionScreen.jpg so when you go to render as, if the loop region box is checked, it will only render that part of the video.

Maybe uncheck the “render loop region only” box in the render as window before rendering your video and see if that helps.
