Does this video stutter?

I don't if this will violate the Youtube policy as they don't allow uploading the copyright contents onto the site.
But here's a prove:
http://www.youtube.com/watch?v=m-JQbgFo670
Ok, yes, my camera sucks, and only allows 15 seconds of video.
This is on my Rev.A 1.6Ghz MBA.
Yes, it stutter the first few second while buffering, I guess my 8Mbps cable isn't faster enough for it
For this test, I let it buffer runs to full to sort out the bandwidth problem.
And yes, the AC power was attached, because my Coolbook setting for the battery was limited to 800Ghz, I tried to change the limit upto 1600Ghz, it runs smooth, no shutter.
And I checked the CPU usage while running, it's idling at around 20%
I haven't check which version of the flash I'm running, if someone can advice how to check, I'd be glad to check for you.
But I don't remember I've updated flash done, so it's probably old version.
BTW, I will have the Rev.B 1.86Ghz in my hand tomorrow, will let you guys know how it goes.
Let me know if you guys have any comments.

Thanks poky for sharing the expirence and for letting us know that coolbook can ease the process of watching such videos.
I would really love to hear from you regarding your experience with revB. I made this poll in the hope of finding some other people with 100% working revB machines and hopefully you will be one of those.
Please let us know your experience with and without coolbook if you do not mind

Sure did. You tested it at the store, then showed off your 'knowledge' to a store manager, then ran home to write this post.
how about the part where I waited for a "FULL BUFFER"?!?!?
I had to go to the store in order to have revA vs. revB.
No idea. Not sure there are any proxy servers that would allow me that much bandwidth to support HD video streaming.
I don't have a MBA, but what you're saying is exactly opposite to everything I've ever heard or experienced about flash 10 video to flash 9 video. I've heard lots of complaints by everyone on all platforms that flash 10 video has MUCH worse performance than flash 9 video. Perhaps you're thinking of general flash performance, but not flash video? On my ancient 1ghz powerbook hulu video played perfectly, then I updated to flash 10 and hulu's frame rate seriously dropped and it stuttered, then I downgraded to flash 9 again and hulu videos played perfectly again. When I researched the topic I found that lots of other people were experiencing the same thing, even on MS Windows also.
Interesting experiment. However, this is not a case of MBA capabilities.
We would have to test a much larger number of 720p videos to reach a conclusion.
I am on Flash Player 10 on a RevB 1.86GHz SSD and could not watch the movie it was stuttering so frequently.

I do not have any now since I got rid of my revA long time ago and I returned my revB as many of the members here know besides the one that have been hiding on a cave like you. My experience is well documented and 100% true. Surprisingly, the store still has revA on display next to a revB.
I have no experience with PPC Macs and Flash 10 is only optimized for Intel Macs to my knowledge.

The performance is still abysmal, but it is better than Flash 9 at least on Intel Macs.
To the OP:
Why not start a test using Quicktime streaming video instead of Flash? We already know Flash performance eats the computer alive, but what about something native to the OS?
http://www.apple.com/quicktime/guide/hd/running_the_sahara.html is a good example.
My Rev. B and Mac Mini both run it just fine without stuttering.

Again, flash 10 performance in general may be improved, but that does not mean specifically that flash 10 video performance is better or worse. Just look at the poll results here, the MBA is only intel, and so far there are 3 people saying it stutters on flash 9 versus 8 people saying it stutters on flash 10. That isn't even close to the ball park of a scientific poll, but if you google around you'll see tons of people on all platforms saying that flash 10 video is very significantly less smooth than flash 9 video. To reiterate, we're talking specifically about flash's video performance, which can be totally different than its general performance overall. So even if flash video uses less processor in version 10, if the result is less smooth video playback then that's all were interested in.

That is why I did not start a thread about QT, because we already know that it is smooth
You might want to start that thread to praise the MBA
People can complain about anything even if it isn't correct. I look at benchmarks provided from reputable online news sources such as arstechnica.com to see the frames per second and CPU usage statistics. If arstechnica.com posts about a 4x speed increase then I'm inclined to believe them. My experience with CPU usage might not be reflected in their testing, but the improvements certainly are reflected there.

This entire thread was about video on the Macbook Air being choppy and you just posted that you knew even Quicktime HD steaming was smooth.
h.264 HD streaming via Flash is choppy. h.264 steaming via Quicktime is smooth. Conclusion: MBA is a lesser machine because of crap software from Adobe? Heh..
LinMac, I would not blame Adobe for this because they should NOT optimize their software for every machine on the market. Flash works perfectly on the MB, MBP, iMac and MP so why not on the MBA? This makes the obvious conclusion that Apple is the one that screwed up the MBA not Adobe.
As for why it runs on QT while NOT Flash, I guess we have to ask Apple for a better explanation. Mine is, Flash seems rough on the MBAs CPU which means that Apple should engineered a machine to use well optimized components instead of building a machine around the design.
Steve Jobs said that this is the first machine they started building from outside in where they designed it and then though of how to put a computer inside it.
This is simply bad engineering IMO.
I know that some people would say that I am wrong and that Adobe is the one to blame.
At the end, I totally understand that everyone has his opinion

I have owned more than one revA and they all did not satisfy me without using coolbook.
As for revB, I only owned one and returned it due to the screen issue where I couldn't spend more than 30 minutes reading a PDF file due to the fuzziness of he lines.
I discovered this while trying to convince myself that I should be able to handle the lines and Apple should be able to replace my screen in the future when they are fixed. However, in addition to reading, I watch a lot of videos and I cannot deal with a machine that cannot even run a 720p flash based video.
I went to the store to show the manager what I was talking about since they had revA on display and he was surprised that there was no advantage from revB!
To make a long story short, I loved the MBA but the shortcomings are pulling us apart
.Edit: The only Mac I have now is my lovely 3.06 iMac
Kinda off topic here, but has anyone tried using bootcamp, run on a windows xp to see the stutter still happens?
Perhaps I missed a part of this thread or didn't read closely enough, but how are new MacBooks, old MacBooks, the rev. A MBA, and everything else able to play the video without stutter, while the new rev. B MBA with the 9400m not able to?
People have said that its the Adobe drivers, but is the hardware in the rev B MBA really that much different from the Unibody MacBooks? They use the same processor and integrated graphics.
The major differences are the screen, lack of ethernet, and several minor things not related to video (you'd assume)....

It stutters on the Mac Mini too.
Flash uses the CPU inefficiently and the Macbook Air is by far the weakest machine Apple makes with regard to CPU. Think about it this way, the Macbook at 2GHz will be 800mhz faster than the Macbook Air's lower end version.
Also it isn't a matter of optimizing it for all machines. PowerPC Macs and Intel Macs are very very different, but most Intel Macs are basically the same for Flash since it doesn't feature GPU acceleration yet.
Rev A No stutters
Rev A Refurb - No stutters. I am quite impressed!
I didn't vote because Rev A was not an option
I have coolbook, smcfanControl, and Flash 10 installed
I am uploading a quick 2 minute video to youtube.

It keeps stuttering on both revA and revB right from the beginning. It also keeps stuttering after full buffer.
It works like a charm on the base model MB, so for those who are blaming Adobe's Flash, that is a total BS since both machine are running the same Flash version.
BTW, I tested it on Flash 9 NOT 10, so it might work better on 10.
Please let me know since I am interested in finding more about this issue. The store manager couldn't believe it and he was blaming it on the network, but when I showed it to him after full buffer, he was totally

I ran it on my Rev A, and though the temperature was 186ºF and fan running at 5300rpms, it stuttered during the first minute or so, but ran like a champ thereafter...
Ran it on my MBP 2.5 and it ran flawlessly w/o stutter. What an awesome HD video picture on both the MBAir and MBP...

Thanks thanks thanks WOW ... really WOW
Would you mind telling me what kind of drink do you give to your machine every morning?
Seriously, what are your settings? Flash version? and so on please
This is the most impressive example I have seen so far. Let me know if you would sell me that machine.
