My After Effects preview is all black.

[#1]

Is there a way to repair this? Because every time I try to preview my footage the video shown is completely black. Is there an option to tick or something? This problem started after doing some 3D edits.

It sounds an awful lot like you're looking through the wrong camera OR you've added lights that aren't illuminating your layers. (Or both.)

[#4]

The black preview applies even if I start a totally new project. Also the green rendering line doesn't fill anymore.

Then it's time for all of the details you can muster and some comprehensive screenshots.

I am having the same problem. The preview window is completely black.

I am running windows 10, quicktime 7.7.9, gpu Nvidia 860m, 12 gb ram.

Got the Caps Lock key toggled on?

[#8]

Nope. As you can see it shows what it supposed to be showing on the top left. I am very new to After effects and I didn't have quick time when I first installed it so I was hoping that would be the problem, but I guess it wasn't.

You're zoomed way in on your comp viewer. Change it from 400% to "fit up to 100%".

that fixed the issue for me thanks! Whenever i added or change text it turned the screen black..

I've been experiencing this problem for over a month now. One day my video preview just disappeared. Audio played during ram preview but the video was all black. However, today I finally realized the dumb reason why I wasn't seeing any video! I hope this solves your problem as well...

In the preview panel it says "include" and there are a few icons: a speaker icon, an eye, etc. The eye icon wasn't selected! That's why nothing was showing up. I must have accidentally un-clicked it. Make sure it's selected on your end.

Good luck!

Thank you!
had the same "problem" and the Eye icon was it.

I made sure the eye icon was selected, and it didn't work. Any other solutions?

I had the same problem and I realized that it just changed from Active Camera to Front Camera.
I realized that I could see just some elements and that's when I noticed the Camera's changes. It turned black when I was trying to press I-don't-know-what-keys on my keyboard. There must be a shortcut to change cameras....

Try to purge the application. Go to the menu Edit / Purge / All Memory and Disk Cache. In some cases, the previous ones hosted in RAM and Disk Cache usually give problems.

I ran into a similar problem today, a black preview!

Solution: I realized that when I toggle motion blur active to a precomp containg precoms, while the prcomps contains very wigling particles. It doesn't RAM-preview. Removing the motion blur solve it.

Removing motion blur did it for me as well! After Effects 2020 on a 2014 MacBook Pro.
