Hello everyone,

I have a very big problem !
My PC specs are : 64gb RAM , core i7 6850k, GTX 1080 Ti 11gb, 500gb SSD ,Windows 10 pro
I Have After Effect 2017.2
My problem is that when I'm working on a video or something i click on space-bar (to preview my work), But it doesnt start normally it usually tells me that the FPS is 15 fps and it lags too much!
Although i give the adobe applications 50gb RAM and I enabled CUDA for GTX 1080 Ti with 8gb of Texture Memory and Ray Tracing is on GPU and Disk Cache is 100GB
Please Help me!!
Thanks

I think the only big problem you have is lack of AE knowledge.  First, you can NEVER expect to work like a video editing application,  where you just press the space bar and everything plays back in real time. AE IS NOT A VIDEO EDITOR.  It's an effects, compositing and motion graphics application, used for very different purposes than a video editor,  It functions differently than a video editor. Particularly in the way you view your work -- you don't play, you PREVIEW.  tOTALLY DIFFERENT.I enco...

I found a way who are searching for, even when this solution doesn't work,  please unselect the circled option which enables motion controls while previewing, its slows down playback even if full timeline is cached.

I encourage you to go to AE Help and look at the section on Viewing and Previewing.  There are a WHOLE lot of ways to preview that can help.

A good deal of quality time spent here won't hurt, either.....

Exactly which video on this help page is supposed to help?  I have the same problem.  I'm not looking learned everything before I can learn something.  And, I am NOT pressing the space bar.  I push play.  The video sometimes stops and replays the same section but always it says not in real time.  The video was created in CS5.  I am using CC.  I seem to see this when the original video is somewhat sophisticated in its effects and not for simpler videos.  Again, I'm not looking to study everything on the help site.  I am looking for straightforward help with what should be a common and obvious issue with playback.

You set AE to cache frames for preview. You hit the zero key on the numeric keypad.  AE previews as much as memory & cache will allow and as fast as they'll allow.  This ain't a video editor, Sparky.

So Dave, question. Being as it is that AfterEffects is not a video editor designed for real-time editing, than how do motion designers and animators properly test their animations if they can't see them? How do professionals know how to distance key frames so that they play back organically? Is it just experience, lots of exporting and testing, or another specific method? I'm a graphic design student and I'm just learning the ropes here.

If you work on timing, there is no need for a crystal clear image, if you work on imagery, there is no need for realtime playback.

Most of the time, I work with quarter resolution, sometimes I also skip frames. Also, I use the render area a lot. Mostly it is just a few seconds, sometimes even just a few frames. I press 0 on numpad to render this area only and watch the preview of this part, alternate the values and watch again until I'm happy with the result.

Martin, how can you say "there is no need for realtime playback"? How are you the authority on all motion design? These users have all worked very hard to minimize the resolution of their playback just to get a full framerate. How can you "work on timing" - as you say- without previewing at full frame-rate? This is a serious issue for video creators expecting professional-grade workflows, not highly-compromised shots in the dark.

Looks like Dave doesn't care to answer your very legitimate question. He would prefer to berate the creatives who came here for support.

I think there is some miscommunication here. What I think @MRseif123 is suffering from, is that the cached RAM preview doesn't play in realtime. I am suffering from the same problem once in a while, on a 96gB machine with 3,2gHz 16 core Xeon W, Radeon Vega II, 4tB SSD and 16 tB 4 disk Raid. Can't even play quarter resolution RAM previews in realtime, while Full HD youtube and every other video is running smoothly. That's kind of unexpected, isn't it?

Thanks, but I don't think that is a solution. Most of the time people don't want the controls in their previews, so that option is switched off in 99,999% of the cases, at least in my situation. More: I really never used it in 20+ years.

I have been working with After Effects since it was Cosa Effects. Maybe version 2, I can't remember now. However, this is a huge workflow fail on Adobe's part. No designer, animator or editor can justify or rationalize this fail in playback workflow. I haven't worked with After Effects in a while and I'm stunned to see such a downgrade in effeciency. Even if the visuals would fail, there's no reason audio playback should slow or slur. It's seems embarassinly horrible to think a client could hear their audio playback could sound like a dying battery or stalling car engine. It's simply poor programming and design.  It's a lack of regard to time tested and true workflow. Under "no" circumstances should a 12core MacPro be unable able to play audio on time. No software love or ego can make sense of this level of dysfunctionality. I can simulate 3D destruction effect in Houdini, Maya and real time, MoCap characters in MotionBuilder with real Time audio playing in the background yet slur, sluggish audio in After Effects? Where is the "Adobe Blank Face" Feature?  It would be smarter.
