Only previewing one frame ahead instead of the entire project

[Cyan_Galaxies]

every time i press space to preview the preview instead of playing all of my footage it only plays one frame ahead and then freezes

It looks to me like you have created a fairly complex composition without taking any time to figure out how AE works. Ram Preview depends on available resources. If you are not getting a decent preview purge everything, change comp resolution to Auto instead of setting the resolution in the Comp Panel and set the Magnification Factor to 50% or even less.

AE is not an editing app. 90% of my comps are one shot and under 7 seconds. Your comp looks to be several minutes long and it looks like you are trying to edit in AE. Source video format can also have a tremendous effect on AE's ability to preview. I'm guessing that there is nothing wrong except your expectations and lack of experience.

its not like after effects is having a hard time rendering the video in the timeline.. when i scrub through the timeline it shows the frames without any problem but instantly deletes the cached previews and when i press spacebar it only previews the one frame it has cached cause it keeps deleting the other ones i think this is a glitch and needs to be fixed

I've used AE to edit videos for years.  It hasn't been until recently that these issues have occured.  I used to be able to edit 20 minute videos with ease.  Now it's hard to get a few frames to render.

Same here! I tried everything. the comps is only 8 sec, I deleted many layers and still same problem

i have the same problem, did you find the solution yet ?

Someone suggested disabling Cache Frames when Idle and that resolved my issue.  Try that and see if it works.

After trying many things, this worked for me:

Here is how you can reset the preferences:

Press Alt (Windows) or Option (Mac OS) while launching After Effects. You can release the Alt or Option key when the splash screen appears.

To reset preferences and plug-in cache at the same time, hold downControl-Shift-Alt (Windows) or Command-Shift-Option (Mac OS)while the application is starting. Release the keys when the splash screen appears.
