Read up on basics of rendering and exporting in the online help. You have to use the render queue.
'Extract'? I don't know what you're referring to. Do you mean 'Export'?
If you're asking, how to render and export your movie, the answer is that you do that using the render queue or Adobe Media Encoder.
To add a composition to the render queue, choose Composition > Add To Render Queue.
Or, to use Adobe Media Encoder, start Adobe Media Encoder and drag the composition from the Project panel into the Adobe Media Encoder queue.
Because you are very new to After Effects, I strongly recommend that you start here to learn After Effects:
Doing so will prevent a lot of frustration.
Yeah Export i mean, Ive added to rendering list, and rendered it, and i went to 'File', 'Export' and there are 4 ways i can export, ive tried all 4 and not one use MPEG or AVi or any format thatt Youtube can Recognise. Also Medi Encoding said it only work in the USA... dont know if it thats wrong but thats what came up. :/[URL=http://s1000.photobucket.com/user/goldyj/media/AdobeExport_zps5c7a846c.jpg.html][IMG]http://i1000.photobucket.com/albums/af121/goldyj/AdobeExport_zps5c7a846c.jpg[/IMG][/URL]
File>Export is basically useless. You Make your Movies by adding the compositions to the Render Cue or by adding an After Effects Project to the Adobe Media Encoder. In my 20 years using AE I've maybe used the export function 4 times. I don't know anybody that uses it for anything except starting a flash project or to start a Premiere Pro project.
its worked, thank you all for helping, but one more thing, i have made a 15 seconds intro, and its 2.6GB big, how to i reduce the memory it is? so its a couple on MegaBytes?
You still have a lot to learn about rendering. Drag your file into the Adobe Media Encoder and render to one of the h.264 presets. I use Vimeo and YouTube presets most of the time.
