Not realtime RAM preview on Mac Pro 2013

Hi,

RAM Preview should be cached into RAM so it should play realtime, right? I'm working with standard 1080 HD resolution 25 fps project and it's not playing realtime. It plays OK here and there, but there are some stops and lags. Project is 625 frames long and it will fit just fine to my 32GB RAM.

I'm on Mac Pro 2013, 12 core, 32GB RAM, D700 and 512 SSD. Should be good enough for Motion work.

Any idea? Thanks.

If the project is very large, it will Caton。I use 4-CORE,d700.Very smooth

Hello,

My project isn't big at all. But still, when it's cached into RAM, it shouldn't affect anyway, or am I wrong?
When it's reading from RAM, it should be pre-rendered right so it should only play pre-rendered frames from RAM and Mac Pro's RAM and graphics cards should be fast enough to play without any problem.

Use [ command+R ].I used to use Mobject, is still 23 ~ 25 / 25FPS

Hi,

I'm not sure if you get my point here.

RAM Preview can bog down, depending on the complexity and duration of a Motion project. You should get "better" playback with it, not 100% quality playback. It is one of several options that will help improve playback to get an idea of what you need to change before a final output. But it, honestly, has never been the same as exporting a QT movie file and playing that back. That's just the reality of things. At least it is better than what you get with AE.
