CS4 exports are 5 times slower then in CS2

System:
Windows 7 (64)
AJA Bord
8 Core System
In CS2 it was possible to make UNCOMPRESSED exports apart from the Adobe Media Encoder. In CS4 all exports seem to run thru the Media Encoder. Most of the exports work faster but I did not find a propper way to export UNCOMPRESSED files.
On the "old" system (4 Core - Windows XP) CS2 exports
AJA Avi v210 1920x1080
...in nearly real time. The same file with the new setup takes about 5x realtime. The weird thing though h264 also needs about the same amount of time then the uncompressed files. And the problem is not the RAID connected (copying is faster the real time)
Any Ideas?

Sadly this seems to have no affect on the exporting time. I changed the set
ting USE MAXIMUM RENDER QUALITY (ON+OFF).
Since my input and output is the same (AJA avi v210) the system should not render anything, right?
Uncompressed 8 Bit 4:2:2 Quicktime files are axported in real time. It seems like the problem is the AJA Codec on this Machine.
Again, this is Windows 7 / CS4 and AJA LHE. Maybe I'll have to contact AJA?

var MyXML:XML = new XML(MyXMLString);//Parse the XML ONCE
I have a function called ConvertXML , and to check the
performance i made it loop every frame by calling the following
RunXML function
quote:
function RunXML(Events:Event){
StartTime = getTimer();
for(var i:Number=0;i<100;i++){
var MyXMLArr:Array = ConvertXML(MyXML, false, false);
EndTime = getTimer();
trace(EndTime - StartTime + " ms");
and here is my code for parsing the variable MyXML in
ActionScript 3.0 (ConvertXML function)
quote:
//Action Script 3.0 ConvertXML
import flash.xml.*;
function ConvertXML(RecvXML:XML, ChildBranch:Boolean,
IsTable:Boolean):Array {
var RowArr:Array = new Array();
for (j=0; j<RecvXML.child("*").length(); j++) {
var TempObject = new Object();
for (k=0; k<RecvXML.child("*")[j].elements("*").length();
k++) {
TempObject[RecvXML.child("*")[j].elements("*")[k].name()] =
RecvXML.child("*")[j].elements("*")[k];
RowArr.push(TempObject);
return RowArr;
addEventListener(Event.ENTER_FRAME, RunXML);
The code above run 5~7 times slower then the following
actionscript 2.0 code
quote:
//Action Script 2.0 ConvertXML
function ConvertXML(RecvXML:XML, ChildBranch:Boolean,
IsTable:Boolean):Array {
var RowArr:Array = new Array();
for (var aNode:XMLNode = RecvXML.firstChild.firstChild;
aNode != null; aNode=aNode.nextSibling) {
var TempRecord:Object = new Object();
for (var bNode:XMLNode = aNode.firstChild; bNode != null;
bNode=bNode.nextSibling) {
TempRecord[bNode.nodeName] = bNode.firstChild.toString();
RowArr.push(TempRecord);
return RowArr;
this.onEnterFrame = RunXML;
they both does exactly the same thing.. and yet the
actionscript 3.0 code run 5~7 TIMES SLOWER . why?
i have tried other benchmark, and it seems that actionscript
3.0 perform 10 to 100 TIMES FASTER then actionscript 2.0 , only for
this one it run slower... why?
I also attach all the code for actionscript 3.0
should you want to try the actionscript 2.0 , just uncomment
the ConvertXML and this.onEnterFrame for actionscript 2.0 and
comment the one for actionscript 3.0
Why? have i done something wrong?
Cheers and God Bless,

Although this doesn't answer your specific question exactly,
it's worth noting that most of the time you do not need to convert
XML into an array or objects like it was helpful to do in AS2, as
XML is a native Object in AS3.
For instance, xml.M would give you an XMLList of logins that
would be treated the same was as your desired Array:
var logins:XMLList = xml.M;
trace(logins[0].Username) // "Test 1"
And that takes 0 milliseconds. ;) You can also declare you
XML directly in AS3, you do not need to declare it as a String and
parse it (see attached.)
Don't know what your trying to accomplish so that might not
help you, but I thought it was worth mentioning. I've been using
E4X extensively for the first time in a project and I have to say
that overall it's made life much easier for me.

Results are in: Leopard slower then Tiger on PowerPC

Xbenched this yesterday. Dual booting on a 12" PowerBook...both Leopard and Tiger boot have Dashboard disabled and are running iStat Menu. Though the back end is slight faster, check out the User Interface and Graphic entries...finally explains why I "felt" that Leopard is slower then Tiger on this machine..it is!

The Leopard interface is definitely more graphics intensive (and I have heard suggestions that Leopard transfers more work to the graphics card than earlier versions of OSX). I guess at some level of hardware any processing efficiencies will be outweighed by the load on the graphics card. In other words, can you be sure that your results would replicate on a PPC machine with a more powerful graphics card and more VRAM?

Audition CC export nearly 10 times slower?

So same project...same time selection same computer, same hard drives, same everything.
Audition CS6 takes just under 13 minutes.
Audition CC takes just under 90 minutes?
What exactly is it doing? That means the whole feature we are working on would take almost 13 hours(I tested this gave it an hour and it was pretty close)
Settings are the same same drives same files etc...Whats up? I am suposed to be testing DCP's tomorrow morning(yes I know its close in time but hence the term "test" not mission critical but still important)
Right now my only plan is to render everything in CS6 and just work in CC.
Any thoughts?

*BUMP*
This becoming a serious problem for me. We are about to churn out about 100 - 200 different videos with slightly varying soundscapes and the export time from Audition will cripple the workflow.
For anyone reading or planning to reply (which would be hugely appreciated!) I press 'Export' and it shows the little dialog box saying that is exporting, however it stays on 0% for a huge portion of the entire process, and during this time I can see that no file has been created in the destination folder.
Also, I was very keen to queue exports in Media Encoder, so that even if the waiting time was huge at least they could be stacked, however I can't find a way to do this, so the exports must be done one by one. I have obviously searched for a media encoder functionality, asuming I must be missing something, but can't find anything. If anyone at least know how to do this I would appreciate the information SO much.

CS4 apps are VERY slow to open Windows file browser with File Open or File Save As commands

We are running CS4 on Windows 7 with all available updates installed. Photoshop and the other CS4 applications are VERY slow to open a Windows file browsing window to select files when File Open or File Save As menu options are run -- it can take as long as a minute or two for the window to open. Once the window opens and a file is selected, then opening or saving the file is very quick. The location of the default directory, whether it is on a local drive or a network drive, makes no difference. Any suggestions as to what the problem might be?

The link that I posted earlier is off. Read this one
http://support.microsoft.com/kb/2501584. I discovered in my network that the MS Office File Validation Patch made excel crawl when opening over the network though nothing else changed. At the time I was opening Excel on Office 2003.
You can manually turn this off by editing the registry and tunring it off. Going forward I skipped the patch to keep my sanity. Not sure if this is the same as your issue, but the support article will go into detail how to either have Fix it
clear the issue or change the proper registry keys.
Hope this helps

I bougnt my S5 a month ago and I am having two major issues. The screen is very slow to respond. When the screen is dark and I press the home button, it doesn't come on. I have to press the button anywhere from 4-10 times and then it usually flashes on and back off. It is very, very frustrating. The other issue is that the battery drains very quickly. I have called Verizon numerous times regarding these issues. They tell me to do different things that never help. We eventually did a factory reset and it still has the same issues. Help! It is a brand new phone and unfortunately I am in a new two year contract. Ugh. Is there anyone out there who can help me?

I have done that several times. In fact, every time I call Verizon with my phone problems, they have me do the same things repeatedly. I keep telling them I have already done them but they insist they are SURE it will work this time. It never does. After doing the factory reset and it still not working correctly, they act like they are confused, almost like I am lying. I did what you suggested above on the slim chance it would work this time but it did not. I bought two S5's that day and the other one works perfectly fine. I know I got a bad phone. Verizon just does not listen. It is a bad phone. I just want a new phone that works properly. Is that too much to ask? I bought a new phone that has been bad from day one. Why oh why do I have to spend hours of my time on the phone, in the store, on the computer, trying to rectify this? It shouldn't be this difficult! Help please!!!

An old macbook running 10.6.8 was restored using Time Machine then Snow Leopard was reinstalled and updated to 10.6.8. Now the machine is slow and repair disc permissions results in a cancelled by user message.

Our old macbook was getting a gray screen with flashing ? on bootup. Eventually I restored it using Time Machine then decided to reinstall Snow Leopard since it would not boot. Machine now boots but is slow. Ran repair disc and tried to run repair disc permissions but got a message that it was cancelled by user.
This machine is at least 6 years old and I just want to limp it along until I can afford to replace it in the spring.

You may be smelling it because with the new OS the processor is having to work harder causing it to get hotter then it would with the other OS. I can't say there is nothing wrong, but what could be happening is just that, it's getting hotter so the fan is spinning faster and moving more air so you are getting more of the smell then you would before. I would still continue to back it up, and take it to the Apple Store at a Genius Bar and have them look at it to make sure. Was the computer ever in a smoky environment??

I have an iPad 1 64gb with 3G..

Looks as if it is to do with your iPhone, if it can't find any Wi-Fi networks and they are turned on and set to discoverable, even after restarting the router it's still unable to find it my recommendation is to do a restore through iTunes, the update may not have installed properly, I have an iPhone 4 16GB (Black) running iOS 5.0.1 and it finds my Wi-Fi networks and log's onto them no problem, so clearly the software works, just seems that your iPhone is having a bad time
You've done everything else I'd reccommend, normal re-boot, soft reset, reset network settings.
Think it's time to do a full back up in iTunes and do the restore, then see if that resolves the issue, be sure to let us know how it goes if you do decide to do this.

windows live mail having problem after joining in domain examples incoming is good but sent or outgoing is not there and also send mails are not exporting at the time of live mail exporting time?

This is not usually related to AD issues, but it may be more of a DNS issue. I posted a request in your other thread to post an unedited ipconfig /all of the DC and of the client.
This may help use diagnose this issue and your other thread's printer issues.

Can i export an Imovie project with special effects as a quick time movie then import into final cut express keeping the special effects?

Hi, Can i export an Imovie project with special effects as a quick time movie then import into final cut express keeping the special effects?

Absolutely. Go to File->Export->QuickTime Movie (do NOT use QuickTime Conversion). Make sure you check the Self-Contained box. The export will be an exact copy of your Sequence, complete with any filters or other effects you've added. Import the self-contained movie back into the project (or another project) if needed.

Database export/exports are extremely slow

We run PeopleSoft (PeopleTools version 8.46) applications on Oracle 10g (10.1.0.3). database exports/imports were extremely slow, so when we contact PeopleSoft customer connection, we were advised to modify the init.ora file with the "_optimizer_cost_based_transformation=off". After we set the init.ora file, exports/imports are very fast.
What is optimizercost_based_transformation? will database performance have any effect by setting this parameter? Does anybody has issues with 10g export/import issues?
any help?
Thanks,

Here is the extract from PeopleSoft customer connection -
. Required INIT.ORA Parameters for Oracle 10g
. Change #1 - optimizercost_based_transformation=off
According to Oracle support: "This parameter controls whether query transformations (sub-query unnesting, complex view merging and push join predicate ) are performed using an algorithm that relies only on optimizer cost (new in 10g) or an algorithm that uses a combination of optimizer cost and heuristics (pre-10g). "
Can anbody tell me how extaclty this parameter will affect the performance of the system? Althoght we didn't see any performance issues right now (We are just in the process of implimentaion) Going forward, i am worried to have this im my init.ora file.
Any thoughts/suggestions related to this topic is helpful.
THanks,

Premiere exports and rendering too slow

I’m using Premier Pro CC on a 2012 MacPro (aluminum box) with 16gigs or RAM.
I have to say that being a long time Avid Media Composer editor I am very, very pleased with the UI and overall capability of Premiere. It’s loaded with tiny nuances that Avid should have incorporated a long time ago. I am in love with this software.
Or at least I was until I went to export my files. What a slog! I’m sorry but the exports are out to lunch. A six minute 1080p 23.976fps sequence with a few titles, a basic colour effect and two tracks of audio takes…. 3 hours?!?!?? What the heck? If I was rendering an equivalent sequence in the Avid I’d be done rendering any effects and exporting a source QT by the time I finished this sentence. And if I set that QT up to encode in Sorenson I’d have my MP4 done by the end of this email. And the Avid doesn’t need to use any external hardware to ramp things up. In addition, just typing this email while Media Encoder pushes through the output (even with Premiere closed) is causing my whole system to slow down to a point that I find my computer basically unusable for anything else. 16 gigs of RAM and 2x six core processors and it’s acting like it’s 1996 running OS7.
Now wait, I hear you say, you can do so much more in Premiere. Yes, I can. But the moment I drop, for example, an After Effect link in there…I can feel the system trying to race glaciers - and losing. What I don’t get is if I were to use the the equivalent clips in After Effects doing the equivalent type of effects the render would be way faster than Premiere --- and it’s the same company! And don’t get me started on Speedgrade. I’m better off doing an oil painting of each frame than using that Dynamic Link function. And teh dynamic links are what encouraged me to try all this in the first place.
Pre-rendering everything is not only awkward but appears to have no effect on the export time - or playback for that matter. In fact I find the rendering of effects rather confusing and horribly inaccurate - both in its estimate of time to go and the number of frames to process. And what is a 'video preview’ anyway -is that the number of clips? Effects? Effects and clips? Grains of sand on a beach? And why does it’s number keep going up too? It just keeps climbing for no reason I can see. C’mon Premiere…it’s basic math- you count how many frames and then that’s the total number of frames. Why are you recalculating? And did you borrow your time estimate code from Windows 98’s progress bar? One thing it does tell you accurately is how much time you’ve been waiting. That’s handy (not). Oh and I sooooo love the fact that if I quit the rendering process it keeps NOTHING from what it did before. So i have two choices: quit this seemingly endless render to try something else only to find it didn’t help ... or stay put and watch my life drip away into nothingness. Right now, on a second sequence, it says "ETA - 13 seconds left" for, like the LAST 2 hours.
I can’t help but think Premiere is too caught up on render-free editing and it’s glorious Mercury Engine when they should be making it faster & easier to render effects for smoother playback and much faster exports. In my Media Composer I may not have as much robust real time function as I would like but it doesn't choke on the basics (title, colour crrection, dissolves) and the renders are so fast I don't care that I even have to render.
Maybe I’m doing something wrong but I’ll be damned if I know what. And no one else is talking. As I skip around the Google-sphere I’m amazed how many people are posing about speed issues (very common Google search result) and so many other editors are retorting “seems pretty normal to me”. No it ain’t. This is NOT normal. This is painfully slow and in no way reflects the current state of speed for import & exports in NLEs.
I’ve watched every tutorial I could find, picked over every preference, closed every other application, tried different media types, purged every bit of cache and even restarted with no discernible difference. At this stage I’d be thrilled to find out if I’m doing something wrong. But until then I’m afraid this software will not be a regular part of my tool set. This is very disappointing from Premiere given how everything else seems to work so well. Such a shame. This software could kick some serious butt otherwise.
Maybe Premiere will announce that they have a new render engine at NAB?…crossing fingers? Don’t think so.

Thanks for the reply SAFEHARBOR11.
I agree, something isn't right. I've watched tutorials where the renders appear to happen in a "reasonable" amount of time and the numbers of frames and videos prviews never increases. So I don't know what is going on with me.
While I have researched into render/don't render workflow with Premiere I can say I tried both ways only out of desperation.
For my system, a MacPro from 2012, we got only one choice for a video card from Apple - ATI Radeon HD 5870. I tried to get a CUDA enabled card (3rd party) installed but despite tremendous research I could not find something that was authorized to work on my system. At the time I wanted the CUDA to accelerate by Sorenson encoding.
One 2011 post suggested that my issue was related to corrupt media. They had suggested that I try and isolate the timeline down by testing one section at a time with exports until the exports went from fast to excruciatingly slow. As I was working on multiple sequences without common media between them I had reasoned that the software may not have liked my Sony F5 native media (although it plays it just fine). So I took the time to transcode all my footage and use that instead— with absolutely no difference. Even if it did make a difference I’d be disappointed because working natively with my media in Premiere was a huge time saver, unlike the Avid which claims to work with native media but really it leaves the system and editing sow & unresponsive so I usually end up transcoding anyway.
My media encoder settings were the template h264 as a Youtube 720p, 23.976 file. Nothing remarkable there. (Although I did try other settings to see if that affected anything - it didn’t).

Very strange : Export from Organizer extremely slow

Today I came something strange while "exporting Files as New File" from the Organizer. I decided to report it, because the observation may point to a potential improvement.
In the Organizer (PSE V7), I went through File--> "Export as New File..." to export approximately 350 Jpeg Photo-Files (around 3 MBeach) to a USB Stick. I was knowing that writing to my USB stick was slow. But the Export Process was much slower than expected. It was ***extremely*** slow and after more than 1/2 hour, only 16% of the Photos had been exported. Also my PC (Windows XP Professional with SP3) was extremely slow in responding.
I therefore diced to kill the PSE Organizer.
Then I decided to 1) export the 350 Jpeg Files first to a Folder on my ***internal*** disk and then 2) to copy with Windows Explorer that Folder to my USB Stick. This was much, much more rapid.
From this experience, I get the impression that the "Export as new File" logic of PSE is doing something very vstrange and very inefficient ...something that could get probably improved.

I may not be having a snow leopard problem at all.
Going back to an old project in 1080i of an 8 minute length. the estimated time to render is about 50 minutes it says @20% of the way thru. Thats about 6x real time.
Maybe thats what I should expect. I was hoping for a significant speed increase in rendering times with the new OS. What is teh factor averaging for other people ?
I am rendering down to 720p multi pass 2320 kbit rate .MP4 in h.264
Maybe I have a settings problem in project properties in my other project.
I also got inspired and moved the render folders to a separate disk from the source files and put the caches on a 3rd drive. my I/O readings now are at 60 reads/sec.
Thanks for helping me work this issue out with you guys. Will keep you posted.

CS4 exports are 5 times slower then in CS2
