My video in AE is laggy and choppy

Whenever I press the space bar and playback my video it turns out all choppy and laggy. I use After Effects CC 2018, on a Mac Book Pro. I know it is not trying to render the effects because from the moment I import it into a composition it's laggy. I edit for fun so I don't know much about my computer and about my settings on AE. I've looked up many videos and forums but none of them showed my problem.

If someone could just help me that'd be awesome.

Thanks.

As Dave said, AE is not like an editing application - previews take time to build. Once the preview is built, it should play smoothly, but will be dependent on your Preview settings. It's possible, for example, to intentionally be skipping frames, previewing at lower resolutions, etc. Open up your Preview panel and take a look at the settings. You can alter the preview settings per hotkey.You can learn more about these settings here: Preview without rendering in After Effects It sounds like you ...

Hit zero on the numeric keypad.  Wait a bit.  The preview will come.  This ain't a video editing application like Premiere Pro, and it doesn't work like one, either.

It worked but still when I press the spacebar it's laggy.
