I/O Accelerator

Hi all,
I see the following in the Cisco MDS 9000 Family I/O Accelerator Configuration Guide
Limitations and Restrictions:
IOA clustering framework uses IP connectivity for its internal operation. In Cisco NX-OS Release 4.2(1), if an IOA cluster becomes nonoperational due to IP connectivity, IOA flows are brought down to offline state. In this state, the hosts may not be able to see the targets. To accelerate the IOA flows, the IOA cluster must be operational and there must be at least one IOA switch in each site that is online within this IOA cluster.
http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/sw/nx-os/configuration/guides/ioa/ioa_config.pdf
Does this in effect mean that SAN IOA functionality is totally dependent on the reliability of the IP network between the cluster nodes?
thanks ...

I don't know if you already got the answer, but I think you can use IPoFC functionality to maintain unified FC and IP traffic for cluster management. However, I've never used interface vsan strategy, so any input will be still welcome :-)

Media Encoder CC not using GPU acceleration for After Effects CC raytrace comp

I created a simple scene in After Effects that's using the raytracer engine... I also have GPU enabled in the raytracer settings for After Effects.
When I render the scene in After Effects using the built-in Render Queue, it only takes 10 minutes to render the scene.
But when I export the scene to Adobe Media Encoder, it indicates it will take 13 hours to render the same scene.
So clearly After Effects is using GPU accelleration but for some reason Media Encoder is not.
I should also point out that my GeForce GTX 660 Ti card isn't officially supported and I had to manually add it into the list of supported cards in:
C:\Program Files\Adobe\Adobe After Effects CC\Support Files\raytracer_supported_cards.txt
C:\Program Files\Adobe\Adobe Media Encoder CC\cuda_supported_cards.txt
While it's not officially supported, it's weird that After Effects has no problem with it yet Adobe Media Encoder does...
I also updated After Effects to 12.1 and AME to 7.1 as well as set AME settings to use CUDA but it didn't make a difference.
Any ideas?

That is normal behavior.
The "headless" version of After Effects that is called to render frames for Adobe Media Encoder (or for Premiere Pro) using Dynamic Link does not use the GPU for acceleration of the ray-traced 3D renderer.
If you are rendering heavy compositions that require GPU processing and/or the Render Multiple Frames Simultaneously multiprocessing, then the recommended workflow is to render and export a losslessly encoded master file from After Effects and have Adobe Media Encoder pick that up from a watch folder to encode into your various delivery formats.

AME takes a long time to start encoding when using GPU Acceleration (OpenCL)

Have had this issue for a while not (current update as well as at least the previous one).
I switched to using GPU Hardware Acceleration over Software Only rendering. The speed for the actual encoding on my Mac is much faster that software only rendering. However, more often than not, the encoding process seems to stick at 0% waiting to start for a long time, say anywhere from 1 minute to several minutes. Then it will eventually start.
Can't seem to find what is causing this. Doesn't seem related to any particular project, codec, output format or anything else I can see. I'd like to keep using GPU Acceleration but it's pointless if it takes 5 times as long to even start as rendering by software-only would. It doesn't even pass any elapsed time while it's hanging or waiting. Says at 0 until it starts. Like I said, once it starts, it's a much faster render than what the software would take. Any suggestions? Thanks.
using an iMac, 3.4Ghz, 24GB RAM, AMD Radeon HD 6970M 2048 MB

Actually, I just discovered it doesn't seem to have anything to do with OpenCL. I just put the rendering back to software only and it is doing the same thing. hangs for a long time before it starts to run. Activity monitor shows it running 85-95% CPU, 17 threads and about 615 MB of memory. Activity Monitor doesn't say its not responding, it just seems kind of idle. It took almost 7 minutes for it to start rendering.
1- Running version 7.2.2.29 of Media Encoder,
version 7.2.2 (33) of Premiere.
2- Yes, a premiere project of HD 1080 source shot with Canon 60D, output to H.264 YouTube 720, fps 23.976
not sure what you are referring to by native rendering. The rendering setting i tried now is Mercury Playback Engine Software Only if that is what you are referring to. But OpenCL gives me the same issue now.
3- H.264 YouTube 720, 23,976 - seems to happen on multiple output types
4- In Premiere, I have my project timeline window selected. Command-M, selected the output location I wanted and what output codec, selected submit to Queue. Media Encoder comes up, the project loads and I select the run icon. It preps and shows the encoding process setup in the "Encoding" window, then just sits there with no "Elapsed" time occurring until almost 5-6 minutes later, then it kicks in.

I am using Flash Got to integrate my Download Accelerator Plus into FF7, now, in the Advanced options tab, I have C:\Users\SCARLET\Downloads, so my games can be d/l there, but they are not, they're going into another folder. HELP!

Well, basically, I want my game downloads to go into that folder. When I used DAP with Flash Got the first time, it did. Now, it doesn't want to go there. It only goes into the "My DAP Dowloads" folder. I checked the Flash Got website, but when it explained about the Flash Got options, it didn't give any help about that?

Many thanks.
With those symptoms, I'd try the following document:
Apple software on Windows: May see performance issues and blank iTunes Store
(If there's a SpeedBit LSP showing up in Autoruns, it's usually best to just uninstall your SpeedBit Video Accelerator.)

How do I disable the hardware acceleration in Flash player on a Windows XP machine remotely?

How do I disable the hardware acceleration in Flash player on a Windows XP machine remotely?
I have a few hundred computers running Adobe Flash Player.
The operation system is Windows XP.
They are Compaq 6005 desktop PC’s, with an inbuilt ATI radeon HD 4200 video card.
We have a persistent issue where viewing a flash video (e.g. something on youtube) causes the video card driver to crash. You are left with no video signal to the monitor. Audio continues and the computer still responds to commands. This only happens when watching flash video.
We have tried:
Updating flash plugin (numerous versions)
Updating the video card drivers (we have tried the last three video card driver versions, including the HP drivers and ATI drivers)
Updating the browsers (this problem happens with IE8/9 and Firefox10/11/12)
There seems to be two ways to work round this issue. One is to disable the video acceleration in the ‘troubleshoot’ section in the advanced part of the display settings area in windows. The other way is to start a flash video, right click, go to ‘settings’ and untick the box marked ‘Enable Hardware Acceleration’.
Doing either of these things allows the user to view flash videos with no apparent issues.
Is there a way to disable the hardware acceleration in Flash without visiting the PC? Perhaps an undocumented option in the mms.cfg file? I understand that you can use an option to skip the video card check, and so force hardware acceleration on, can you do the opposite?
Thanks in advance
Daniel.

Hi.
I have had over 200 views, and no suggestions as to how this could be fixed.
I have also posted in the general flash forum, that thread has fewer views.
If I should put this question in a different forum please let me know which one.
If what I am asking is not possible is there a mechanism for escalating this issue or requesting a feature for the next version of flash?
Thanks.

How do I use an SSL Accelerator with iWS 6?

I have an application that uses iWS 6 sp2 and iAS 6 sp4. The web server exposes a https port. I can get this port to work fine with a certificate requested against the internal module. When I use the module supplied by the SSL accelerator (Sun Crypto Accelerator 1) I can install and view a certificate, but I cannot start the web server. I get the following error in my logs:
[18/Mar/2002:15:57:17] failure ( 2820): Invalid configuration: File /usr/local/iplanet/servers/https-www.exsel.org.uk/config/server.xml, line 22, column 390: SEC_ERROR_BAD_DER - Certificate is improperly DER encoded : unable to find certificate Server-Cert
I can see a certificate by this name in the cerfticate database for the additional module. I can view it and it looks good (I'm generating my own certificates at the moment - so I know that the internal and external certificates were generated in the same way).
Has anyone any experience of using this combination of things?

I think you are getting your certificates crossed up some how. "Server-Cert" is normally the name of the internal certificate. See what the name of the one installed on your accelerator is and change the name in server.xml to match that. Be sure to backup up all your files first!

Hardware Graphics Acceleration

As many users have noticed, there’s a new feature which is introduced in Office 2013 called "Hardware Graphics Acceleration", which sometimes is also called as "GPU rendering". The purpose of course is to improve performance.
As stated in the System Requirements for Office 2013, Graphics hardware acceleration requires a DirectX10 graphics card and a 1024 x 576 or higher resolution monitor.
A graphics processor helps increase the performance of certain features, such as drawing tables in Excel 2013 or transitions, animations, and video integration in PowerPoint 2013. Use of a graphics processor with Office 2013 requires a Microsoft DirectX
10-compliant graphics processor that has 64 MB of video memory. These processors were widely available in 2007. Most computers that are available today include a graphics processor that meets or exceeds this standard. But, if you or your users do not have
a graphics processor, you can still run Office 2013.
(http://technet.microsoft.com/en-us/library/ee624351(v=office.15).aspx)
The option of hardware graphics acceleration can be found in any Office applications from
FILE -> Options -> Advanced ->
Display -> Disable hardware graphics acceleration:
This setting can be controlled by the following registry key:
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure
that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry,
http://support.microsoft.com/kb/322756
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Graphics
DWORD: DisableHardwareAcceleration
Value: 1 to disable, 0 to enable
Administrators can deploy this setting using Group Policy as well. Follow the steps below:
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these
problems can be solved. Modify the registry at your own risk.
1. Add the following files to your domain controller: Office15.admx and
Office15.adml files to your domain controller and then
2. In the Local Group Policy Editor, select the Miscellaneous node of the
Microsoft Office 2013 tree. This setting is shown in the following figure.
For more information about how to use .admx and .adml files for Group Policy administration, go to the following Microsoft TechNet website:
How to manage Group Policy ADMX files
Please note the change is global: Changing this option in a single Office program also applies to other remaining Office programs. So you don't need to follow these steps for all Office programs one by one. If you want to just disable animations in Word
but leave them on in Outlook, no we can’t.
When do we need to disable Hardware Graphics Acceleration?
I’ve seen in some cases users complain that Office Applications are laggy and slow, sometimes even hang/freeze. They have tried many things but couldn’t figure out the root. Actually, the animation sometimes can slow the performance down, once they disable
the Hardware Graphics Acceleration, the problem is gone.
There are also issues like blurred text/font, cursor hangs randomly in Office applications, we can disable this simple option to see if this fixes the problem.
Please note, the Hardware Graphics Acceleration option is not the only option that may cause issues. For example, an user needs to turn off the animation to improve the performance of Excel, but it doesn’t have any effects after disabling Hardware Graphics
Acceleration. Now let’s check this Windows setting:
On the Desktop, right click on This PC(or Computer) icon, select
Properties, then Advanced system settings on the left side, under
Advanced tab, click on the Settings button for
Performance.
Now we see this:
Uncheck the box for Animate controls and elements inside windows, click
OK button.
Now the problem should be gone.
Another case:
If you have blurred text/font issue in Word, you may consider to disable Hardware Graphics Acceleration. If this doesn’t help, what to do next?
Please go to FILE tab -> Options ->
Advanced -> Under Disable hardware graphics acceleration, there’s a checkbox for
Use Subpixel positioning to smooth fonts on screen, uncheck it and click
OK. The blurred text/font should be gone.
Summary
In this article I introduced how to configure Hardware Graphics Acceleration from applications, the registry and Group Policy. There are also some issues it may cause and what we should do to resolve them. If you have any ideas about this topic or any other
comment, please feel free to post in the forum, thank you.

Is there a way to disable mouse acceleration in OSX Yosemite?

i have used my dads iMac and MBP in the past and always noticed how bad the mouse response was in my opinion. Mind you, some people like the way the mouse responds in OSX and will probably have no idea what my issue is. That is mouse acceleration and the lack of option to disable it in the mouse settings panel. Here is a good explanation about what it is, also in the video is a visual example.
"Mouse or cursor acceleration, to put it simply, makes the travel distance of your cursor on the screen reliant of the velocity of your physical mouse movement rather than just the distance that you move your mouse. So making one movement of the same distance at two different speeds will cause two different relative cursor movements, with quick movement causing the cursor to travel a greater distance."
source:
https://www.youtube.com/watch?v=16diwK6HWbI
So the thing i want to accomplish, is making the physical mouse movement one-to-one with the cursor speed on the screen. As an example: moving my mouse 10 cm would always make my mouse on the screen go 1000 pixels, no matter how fast i move my mouse.
I've had my mouse set up like that in windows and linux for quite some time now and i hope there is an easy way to set the mouse response like that in OSX as well.
I want to make clear that this isn't just an issue in games where you want to have great mouse precision. I have become really accustomed to this way of mouse response in any type of application. So the problem lies not in any mouse settings of any game/program. The problem lies in how OSX translates physical mouse movement to cursor movement.
Anyway, i ran into this issue about a year ago when i was using my dad's computer. i've had my own windows computer for some time now. An option to disable mouse acceleration in OSX Yosemite might have been implemented properly in the mean time. I have searched this community and found some old posts of people who had this same problem as me, but never read about any fix for it. The main reason i am asking this is because i am considering buying a Macbook.
I'd rather not use any third party software, but if there is any out that that just works and is easy to use, let me know.

Please don't be obnoxious to people like tbirdvet trying to help; nobody here owes you an answer, or anything else for that matter.
Anyway, Yosemite seems to enable mouse acceleration by default. You can disable it to get a constant pixels pointer moves / meters mouse moved ratio by typing this in terminal:
defaults write .GlobalPreferences com.apple.mouse.scaling -1
you'll need to logout and log back in for changes to take effect. To restore the standard behaviour:
defaults write .GlobalPreferences com.apple.mouse.scaling 2
should do the trick.

How to check whether Java 3d is using hardware acceleration?

Hi
I just started looking into Java3d api. I am going through the tutorial examples. When I run it on Windows with JDK1.4.2, the app runs, but taskmanager shows cpu usage is around 55% of my 3GHz Intel processor.
I am sending the following VM parameters
-Djava.library.path=C:\progra~1\Java\Java3D\bin -Dj3d.rend=ogl -Dj3d.debug=true
I tried Direct3D as well by passing -Dj3d.rend=d3d. I don't see much difference in cpu usage. The sample I am playing is the one where you create a ColorCube and rotate it on a timeline. Pretty straight forward code taken from the tutorial.
I am wondering
a) Why is my cpu at 55% if it is using h/w acceleration?
b) Is there any way to find out whether Java is using software renderer vs h/w renderer.
I used sys internals processexp tool to look at the stack of java thread that is spinning the cube. I don't see any references to opengl or j3d dlls in the call stack.
I appreciate ur help.
Thanks

How can I open a project that has been created with Mercury Playback Engine GPU Acceleration software, on my trial version of Premier Pro CC?

Hi,
I'm working with a colleague who is using Mercury Playback Engine GPU Acceleration software on his PC version of Premier Pro CC. I am using a mac and have a trial version of Premier Pro CC. When I try to open a project file that he has sent me I get an error message-
"Missing renderer: This project was last used with Mercury Playback Engine GPU Acceleration (CUDA), which is either not available or not certified on this system. Mercury Playback Engine Software Only will be used."
When I click OK and locate the files I get a message saying "File format not supported".
Can anyone tell me what to do so that we can share project files?
Many thanks,
Jessie

Shouldn't really be the MPE at fault here ... what is the codec of the footage/sequence/project?
Second, can you create a new project in PrPro, then in the media browser, import that sequence from the other project?

Multiple crashes fixed by turning off hardware and Flash acceleration; very slow now. Takes five seconds to exit and still listed as a running process

A workaround was suggested by a member of the community to turn off both hardware and Flash acceleration. It worked fine (no crashes since), but runs very slowly. In particular, takes five seconds to exit and is often still listed as a running process. Very slow in connecting to Web pages, and very slow loading them because of the graphics. Very slow in loading video. I expected slower responses, but this is REALLY slow. I'm running 64-bit Windows 7 and an Nvidia GE Force 7800 graphics card with all the drivers updated and the plugins for Firefox mostly set on "ask to activate". Should I expect this much reduction in performance when the workaround I mentioned was put into place? If so, it's half a loaf at best. The only thing questionable is that I have two Youtube downloaders that I am trying, but I made the assumption that these were only applied when you downloaded something from Youtube.

In case you are using "Clear history when Firefox closes": do not clear the Cookies
If you clear cookies then Firefox will also try to remove cookies created by plugins and that requires to start plugin-container processes that can slow down closing Firefox.
Instead let the cookies expire when Firefox is closed to make them session cookies.

Playback and Rendering issues when GPU acceleration is enabled

I'm using the new MacPro with dual AMD FirePro D300. When I enable GPU Acceleration (Open CL) I can no longer play through an entire sequence. It specifically has issues playing through any layered graphics or titles, but seems to play with those disabled. I have tried having "Composite In Linear Color" enabled and disabled, and neither seemed to make a difference. It's the same deal when rendering. If I have titles, and use GPU Acceleration it jumbles clips, cuts to black or static, all manner of weirdness. Is there something I'm missing?
An example of what playback looks like if I have titles and GPU Acceleration enabled.

This computer thing seems complicated enough that if your system works better with GPU accel off, that's you best performance. I understand they've been trying to sort out these sorts of issues but there's so many dang variables, and trying to build software that interlinks with other complicated software is something no other NLE or Grading program does. That throws even more kinks into the list.

IMAC's Top graphics card frustration - Cheap and no support for Adobe Mercury Playpack Engine GPU Acceleration?

If anyone has a solution for getting the Mecury Playpack Engine GPU acceleration to work with Premiere Pro CS6 on an iMAC 2011, please let me know. Like I wonder if you could Thunderbolt an External graphics card somehow? Or is an upgrade possible? Ahh...not worth the risk.
Please, if you have a solution for me, let me know. Otherwise I find it pretty frustrating that I purchased a top-end iMAC, fully maxed-out in every way possible, and that the iMac doesn't support Adobe Premiere's Mercury Playback Engine GPU acceleration. Also, an old USB 2.0 Hub and thus the built-in SD card reader is slow. If you have SD cards with 95MB/s Transfer, Read and Write speeds, the iMAC will only transfer at around 30MB/s if you're lucky. Technically 480Mbs which is around 50MB/s but I haven't seen those speeds.
I figured this could at least be circumvented with a Thunderbolt SD card reader or a Thunderbolt to USB 3.0 adapter but of course no such thing exists.
Well, nothing with a reasonable price tag. This all might seem trivial to some but when you're uploading 24 hours of HD video footage from a 128GB SDXC card, the speed makes a big difference.
And come on, no BluRay support? Ridiculous. I get the politics of why but still, just ridiculous. It would be nice to be able to burn a BluRay to watch in my home theater system. There are other methods but BluRay is convenient and great for backing up large Video Files. Unfortunately BluRay looks like it's not going to make it. Maybe cable distribution companies will increase their Internet upload speeds one day and I can just store everything in the cloud and watch full length movies(that I've created) on Vimeo.
Anyways, I went and took a look at the hardware Apple stuffed inside my fancy (3.4 Ghz i7, 16GB 1333 DDR3, 2GB AMD 6970M, 256 GB SSD Internal and 2TB 7200 Internal) machine and it appears to be pretty middle of the range stuff. It's an iMAC, not a Mac Pro so why am I griping? Because my 2009 PC(which I tricked out over the last two years) is faster and does support the Mercury Playback Engine. I spent $2100 total on this PC which includes all my upgrades. I spent around $3300 on the iMAC. I feel ripped off.
Yes, I do love my iMAC on multiple levels but had I known my dated 2009 PC would render video projects faster, I would have gone with a MAC Pro or just a new PC. It seems that Mac is moving completely away from making high-end computers for niche markets(video editing) and focusing on their tiny laptops, IPADS and IPhones for the masses. Obviously smart from a capitalistic perspective(at present at least) but very frustrating for some.
I was actually told to purchase a MAC for video editing. I've been a PC guy for 15 years. I went with the iMAC because I had read many good things about it(probably just Apple propaganda) and also the MAC PRO was to be discontinued. Also the MAC Pro would have been triple the cost for what didn't seem like a whole lot more.
It's one's thing to prepackage a computer with inferior hardware(the iMAC I have is fast for most things and more than enough for 99% of the population) but to not allow us to pop open the computer and make a quit upgrade to the machine is what really makes me feel like I'm using a computer built for Grannies. I mean there is a reason my mother loves iMacs and Iphones. Amazing that I was able to upgrade my memory from 4 to 16GB but I've heard Apple has even done away with that. I get why they do it. Apple Warranty, Apple Care issues, Profit and World Domination: Apple wants a monopoly on everything.
Was great to see Adobe bounce back after the whole Flash/HTML5 thing and knock Final Cut Pro off the face of the Earth for good. People are still buying it b/c of the brand name but Final Cut is done. David Fincher used Adobe's Workflow for everything when he made The Girl with The Dragon Tattoo. Hollywood is making the shift and the world will follow. The Adobe Workflow has finally come together and there is just no way Apple can compete with Adobe Creative Cloud and an Engine that can just swap from Premiere to After Effects to Prelude to SpeedGrade to Photoshop to Story with speed for $29 bucks a month(or $49 for some). Apple better start supporting Adobe's Mercury Engine or they may have a problem. And if you're using Final Cut X, you're severely handicapping yourself. Problem is that people don't want to take the time to learn Adobe's products(steep learning curve for sure) which is where Apple's Granny software, and perhaps computers, comes in to play. Arnold Schwarzenegger once said "Milk is for babies, Real Men Drink Beer". I'm beginning to think that "Mac's are for Grannies, Real Men Use Adobe and PCs".
The major problem with Apple is you're forced to use Apple. Not sure but history has proven that people don't like to be forced into anything. Autocracies don't work. These systems eventually topple, even in the corporate world.
Amazon.com, now that's the company to emulate. What an amazing machine!
I've read that Apple may even discontinue the iMAC after 2013. Who knows?
If anyone has a solution for getting the Mecury Playpack Engine GPU acceleration to work with Premiere Pro CS6 on an iMAC 2011, please let me know. Like I wonder if you could Thunderbolt an External graphics card somehow? Or is an upgrade possible? Ahh...not worth the risk.
1) Graphcis Card - AMD Radeon HD 6970M 2048 MB (6990 would have been better or something from NVIDIA.
2) USB 2.0 Hub with only 480 Mb/sec
3) Seagate Baracude SATA I 7200 RPM drive with 3GB/s transfer rate and only a 32 GB Cach. It's ok. I would have expected at least a Western Digital Caviar Black 2 TB SATA III 7200 RPM 64 MB or the Velociraptor at 10,000RPM.
4)APPLE SSD TS256C Flash Drive. As you can see, it doesn't stack up so well against other SSD Drive.
Just average. http://www.harddrivebenchmark.net/hdd_lookup.phphdd=APPLE+SSD+TS256C

Whining and ranting about how iMacs can't do this or iMacs/orMacs can't do that is not going to get you a lot of help here.
Your "I love my MAC" is typical of the ever ubiquitous PC whiner.
If your video work needs were that computer intensive and critical , you should've done some online research and you should have budgeted for a Mac Pro.
Mac Pros are completely expandable and upgradeable unlike the iMac.
Mac Pros have much more faster and more CPU cores than the iMac line.
iMac line is limited to CPUs with 8 cores. The Mac Pros, I believe, are up to 16 core CPUs, now.
The Mac Pros can have their GPU upgraded and you even add/expand to use specialty audio/video cards.
Mac Pros are the defacto standard for real video work.
iMacs, even the high end model, is not really designed to do really heavy and intensive video work.
iMacs do do video creation and editing. Just not on the level that is needed from a more "Pro" computer.
It seems to me you are asking your iMac to do more than it was originally designed for, in terms of professional video editing.
You get a lot more out of a Mac Pro than an iMac for any real serious video, CGI or animation work.
You just didn't want to spend that much cash on one.
iMacs are not user upgradeable or friendly to user upgrades at all!!!
If you purchased a Mac Pro, you could've had that better, faster HD, better faster SSDs.
That said, I can offer no real help to but because of the nature of your post and the fact you just simply annoyed me, I feel some advice and explanations are in order
First off, you picked Adobe video editing software suite as your video creation software on the Mac. It's no secret to long-time video content creators on the Mac that Adobe products, especially those for video creation and editing are very user unfriendly on the Mac. Even though Macs are supported from Adobe, Adobe for a long time has treated the Mac and Mac users as second class citizens.
Before purchasing and installing Adobe Premiere, did you even check Adobe's site for the preferred system hardware and software requirements? Hmmm?
This is why you should KNOW what software you are going to be running on a computer first then research what computer make and model will run said software.
That's why Apple has its own apps like Aoerture, Logic and Final Cut.
Despite your ignorance in this matter, Final Cut Pro X is alive and doing well, thank you, and using this software on your iMac would kick Adobe Premier in the you know whats.
Final Cut Pro X is a complete video solution for and completely designed around the Mac.
Why are you using USB 2.0 connections for video work when you have a perfectly good FireWire 800 connection.
In case you are not aware, FireWire 800 is called so because it has a max throughput of 800 Mbps.
Your 2011 iMac can take up to 32 GBs of RAM. Not just 16 GBs.
This changed when the 2010 model iMacs came out.
Blu-ray? I believe you can buy external Blu-ray writers that work with Mac using said FW800 connection.
So you cite one movie and one videographer using Adobe Premier for your premise that Final Cut is dead in Hollywood?
Your argument that Apple locks you into everything in their world can be countered by saying Windows and Windows PCs lock you into the Windows world. What's your point?
Apple is not discontinuing their computers platforms any time soon.
All you are regurgitating is rumor. Probably from all of the PC crowd.
iMacs and professional desktop Macs are not going anywhere.
Currently, Apple is the only desktop/laptop computer maker that is still making a profit on their Macs and increasing their market share percentages for the last 5 years during which the PC market has continually slumped/dropped in its market share.

Problem with hardware acceleration on HBO GO

I just got a Zotac ZBOX AD02 (AMD E-350 APU w/ Radeon HD 6310) and in general it's working great. However, I have a problem with Flash video on HBO GO. For the first minute or so of steaming video, everything seems perfect. Video is high quality and smooth, CPU is around 50%. Then after a minute or two there will always be some visible video glitch and CPU utilization will jump up to 90-100% and playback becomes extremely choppy. So I'm guessing Flash hardware acceleration is working initially, then something happens that kills the hardware acceleration, and of course the E-350 CPU is not up the task by itself.
The really strange thing is that it seems to be specific to HBO GO. I can stream HD all day long from Amazon Instant Video and Youtube (at least when Youtube is able to dish it out fast enough). And it's definitely not a bandwidth problem. I have Comcast cable (20Mb down), and a bigger computer I have hooked up to another TV has no problem with HBO GO. I think the same problem happens on the bigger computer, but it's faster CPU can overcome the lack of hardware acceleration.
I've got the latest drivers from AMD and the latest Flash player (even tried the 11 beta) and have tried all the main browsers (FF, IE, Chrome), but it's always the same: 1-2 minutes of perfect playback and moderate CPU utilization, then jacked up CPU and choppy playback.
Unfortunately, there doesn't seem to be any way to contact HBO GO directly about this problem (support links just refer you to your cable provider), so I thought I'd give it a shot here. Is anyone else out there having this problem with HBO GO or any other Flash video sites? Any thoughts on what else I could do to track down the root cause?

Well, my idea with 10.x on IE didn't really work. Results were not nearly as good as in Firefox, and I'm not willing to use 10.x in my main browser.
However, based on your insight on the wmode=transparent issue, I started playing around with a Greasemonkey script to force wmode=direct, and I think it actually works. I haven't been able to try it at home yet on the problem PC, but here on my work PC (don't tell anyone I'm not actually working) it makes a massive difference in CPU utilization. Without the script CPU is around 80-90% during video playback. When I enable the script it drops to around 20%. The only issue is that I usually have to refresh the page once video playback starts to get wmode=direct to take effect (start video playback, then once the video playback page loads, hit refresh in the browser).
My script is just a modified version of this one I found:

Here's my modified Greasemonkey script (hopefully the forum will allow javascript in posts):

Is there any way to get mouse scrollwheel acceleration? Very handy...

What I want to get is a similar effect to this windows autohotkey script:

Details:
What is accelerated scrolling?
Normally, when scrolling using the mouse wheel, the number of lines scrolled per notch or 'tick' of the wheel is constant. With accelerated scrolling, the faster you turn the wheel, the more lines you will scroll per tick. Therefore, if you turn the wheel slowly over 5 ticks, you may scroll 30 lines (default 6 lines per tick on Windows), but flicking the wheel very fast over the same five ticks may scroll 50 or 100 lines, depending on your speed.
How does it work?
Normally, one tick of the scroll wheel sends a single key signal to the application. This script works by sending extra key signals when you scroll quickly.
Why should I try it?
I think most people would benefit from using accelerated scrolling. On a daily basis, I see friends and colleagues attempting to scroll a large web page or a long list using the mouse wheel, and they flick the wheel very quickly, many, many times. Not only is that frustratingly slow, but it may contribute to Repetitive Stain Injury if done often enough.
Accelerated scrolling is very intuitive because it's obvious that slow scrolling means the user is reading line-by-line, while fast scrolling means the user is trying to traverse a long distance.
It's clearly not available on most desktop control panels. Maybe it can be done in X config files?
Thanks!

I am bothering with this for quite some time. I have a cheap Logitech mouse and in firefox i can adjust setting but not globally. In KDE system settings there is this option but it doesn't work due to some bug.
I would also suggest you the same as did tell you thisoldman but i had some issues with imwheel - probably because of my limited knowledge or something. In imwheel i could configure it to scroll, let's say, 6 lines but then i had problem with scrolling unfocused windows. It just didn't worked anymore if i ran imwheel. The second pain in the ass was annoyance in libreoffice where wehen i would scroll the text the blinking cursor would also move with the scrolling and all the highlighted text would "dehighlight".
So, if you are not bothered with this then just use imwheel.
