I've just got After Effects and i'm a complete begineer. I'm trying to design an interactive type picture with a wave form underneath etc. Pretty much like this - http://www.youtube.com/watch?v=GznGBOXc6Sk&feature=plcp
Could anyone help me as i'm trying to save myself some money,
Ok i have found out how to add an audio spectrum but the video only plays for 30s and when i render its laggy as ****. Anyone know how to fix this?
You need to look at the basics. The video is probably only 30 seconds because that's what you set your work area to. The video is probably laggy because the default render settings are lossless and that's a production not a playback codec.
Please go through the info on this page. Look in the help files on rendering or type rendering in the search help box at the top right corner of After Effects.
