Recently I'm making a music video in where I add an equalizer effect in adobe after effects. But the thing is that after I render the video only a small portion of the video seems to be rendered properly. The other part is just a black screen with audio. Is there a way to prevent this and fully render my video? Here is a gif of a small portion of the video to have a visual idea of the problem.
I'm guessing that your composition and your layers are not the same length. I can't' tell though because you didn't provide a screenshot of the project with the properties of the problematic layer revealed. Please select the layer that is disappearing and then press the U key twice to reveal all properties that have been modified, then take a screenshot, then post it . A shot of your rendered frame tells us nothing about your project.
