AppAdvice site has developed some small rapid tests for judging the performance of iMovie on the Mac in iPad and basic tasks. The findings are quite surprising: in most of the tasks of copying and coding, the iPad 2 was the fastest, even faster than the MacBook Pro or Mac Pro five times more expensive.
The first test involved the importation of a two-minute video from an iPod touch, 4G towards iPad (with the Camera Connection Kit) and Mac (with the import feature in iMovie). The iPad 2 performs this task in 25.5 seconds, five fewer than the iPad first name, two times faster than a Mac Pro, more than four times faster than a MacBook Air.
For the second test, it was necessary to create an empty project, place the same two-minute video, and then export it in HD 720p: again, the iPad 2 is the fastest. IOS devices end up in a handkerchief, far ahead of the Mac.
Finally, the last test, a bit closer to real conditions: it is this time a small assembly with the same two-minute clip, a title, a soundtrack, and an image to open and close the all exported to HD 720p. This time, the iPad 2 does not prevail: the Mac Pro or MacBook Pro 17 "five times more expensive ones are faster. We note however that the iPad 2 dominates the head and shoulders iOS other devices, this which was not the case in the previous test.
We wanted to check something with an iPad first generation with the latest version of iMovie to IOS, and a MacBook Air 11 "also features the latest version of iMovie for Mac .... The idea was to try to find the reason for these differences: Software Optimization or hardware or difference in the encoding process?
We used a 720p HD video file (H.264) 3:35, just exported in HD 720p. The output file weighs 285 MB side iPad, 262 MB Mac side, and it is difficult to see any difference: in short, the iPad would "cheat" not on compression. But where the MacBook Air is 1:10 p.m. to encode and export the file, does that iPad 03:03 (and this is a first generation model).
It is quite possible that this difference reflects a subtle blend optimization hardware and software with a version designed iOS closer to the hardware platform of the iPhone, iPod touch and the iPad. iMovie on the Mac operating correctly about multiple cores, but it would not be surprised to learn that the IOS version is a massive use of computing by the graphics chip and some advanced features of the ARM platform dedicated to video - it could explain the differences between the two generations of iPad, the graphics chip of the iPad 2 being much more powerful than the first generation. He can only hope that Apple emissions both bolt around the Mac version...
In the forth coming week you may expect a review is about windows7 phone and iPhone comparison.
