AE too slow for me, help !
Hi everyone,
I’m very new to AE so please bare with me..
I got a pentium 4 desktop, 3.0mhz CPU, 1gig of RAM, plenty of HD space and
a NVIDIA 7600GS 256RAM videocard.I simply load up an .avi file of about 15 secondes duration and anything i try to do with it is very very slow ! I mean just using the keying effect to remove a greenscreen in the background and moving my cursor in the workarea is so slow.. while it’s slow like that i checked the running process, AE takes up about 55% of CPU usage(nothing else running), only 500 out of 1024 RAM in use, my HD isn’t swapping… so why is it that slow?? what am I missing please someone help!!
thank you

well, ae is not a realtime app. everything is rendered. you can preview in realtime by hitting the zero on the #s keypad. this will render a ram preview, which, once rendered, will play in realtime.
you can get better performance by adjusting the preview settings to a smaller scale (50%, 25% etc) and the quality (half, quarter…), generally if you cut he scale to 50%, also set the quality to half… if you set the scale to 25%, set the quality to quarter… also make sure that adaptive resolution is on in the preview prefs.
1gb ram is not a lot of ram for ae, your operating system alone will need some of that, probably around 128-256mb. remember that one frame of standard def video is 1mb, so ae will eat up ram quickly.

I’d add at least another gigabyte of RAM and see if that helps.

I have already tried most of what you said except the adaptive resolution part.. I will try it out tonight and i will also buy more memory as suggested
thanks to all who responded !

adaptive resolution should be on by default…. if your nvidia card is supported by ae’s opengl requirements, you may also want to try turning on opengl accelerated previews. opengl can be enabled in the same preview pref. you can toggle between adaptive and opengl in the preview window, there is a small icon on the bottom-right of the preview window that allows you to switch rendering. if open gl is working for you, you can use it to render your final output as well, by setting it in the render settings (it’s a check box). you can find a list of accelerated features and effects in the help menu (or manual), search opengl.
