Anyone know what it would be like editing on a decent laptop whilst using a 1080p monitor would be like. I am thinking of doing all the main editing on the laptop and using the monitor as a screen to see the ram previews in fullscreen. Anyone know if this will work? Thanks
Just so you know, "editing" is what you do in Premiere, Avid, or Final Cut. It is the act of cutting shots together to tell a story.
After Effects is used to create shots. Compositing, Animation, Motion Graphics; these are things that After Effects does. Now, you could actually edit with After Effects, but it would be very painful.
I think your plan is a decent one. (Although, you may not be able to get it totally full screen). I would recommend not using a laptop at all though. For AE, you want a lot of processing power and you get a lot more power for your money with a desktop or a workstation.
