Hi all, I've tried asking Apple this question, but its like talking to a wall. I just keep getting the same basic answer. I'll be hopefully traveling/emigrating to Australia to live for a year or maybe two. I want to get a macbook air for the lightness of them. However, I like to do video editing as a serious hobby for my Youtube channel. Therefore, I'm trying to decide whether or not to get the Macbook Air 11inch core i7 1.8ghz model OR the Macbook Air 13inch core i5 1.7ghz model for video editing. Both are similarly priced and on budget for me. I want to get Final Cut Pro X as an upgrade from Power Director 9 that I have been using for a while on Windows. I would use and have used iMovie 11 but the quality of the export was very noisy in the dark areas of the finished product. That plus all my files are 1080p AVCHD from my camera. I simply want something that can do 1080p video editing for 10 minute projects and obviously they need to be smooth. Its definitely one or the other for me. The Macbook Pro as Apple keeps trying to force on me is too heavy and expensive for my needs. 1200 for me is more than enough to be spending on a computer. I currently have the Macbook Air 11inch core i7 and it did do a 10 minute clip in 1080p with plenty of transition effects with iMovie. It ran perfectly without glitches, but again I found the quality and restricts of iMovie to be substandard for me. This did give me confidence that the Air could video edit no problems though. However, I did see a video of a guy with a 13inch MBA core i5 1.7ghz and he only managed 5 minutes of video before it got sluggish. No idea why though and he wont respond to my comments. I have a feeling it could be ram related or maybe his core i5 was very hot and not performing well or maybe he had many programs open. No idea. Tests from independant sources have shown only a 7% difference in the core i7 and i5 on the 13s so its hard to know what to believe. Has anyone tried full hd video editing on the 2011 MBA's with final cut pro? How long of a video did you make? Just to add, the only reason I want to change to the 13 over the 11 is I think as a main computer (which this will become) the 11inch is slightly too small and the battery life is suppose to be 2 hours more than the 11inch. Its also nice to have more screen space when editing. I've only been getting about 3 hours from my current macbook 11ich corei7 so I wonder if theres much of a real difference. Cheers in advance for the helpful comments!!
