Am I using the right codecs in CS4?

I have been working with PP CS4 for a few weeks and thought it might be good to check with the experts about which codecs I am using. I also just got a new video camera that is an AVCHD type. Here is what I normally use:
Copy video from camera to PC in *.MTS format. I use a USB adapter to copy from the SDHC card.
I start PP CS4 and when I open a new sequence I choose AVCHD 720p30.
Once into PP CS4, I use media browser and open the MTS file into the source monitor.
Next I need to save my work for later use in Encore and I save into Flash for upload to website.
To save for Encore, I export to AVI – video codec DV NTSC
To save for Flash upload, I use Flash F4V – Medium. After saving, I rename the file to a FLV file.
I rename to FLV because my website flash player only recognizes FLV extension.
Once in Encore, I add a menu plus a post roll (scrolling credits), then burn to DVD.
Am I using the right codecs? The one that is most unclear to me is the new sequence one – AVCHD 720p30. My system is an i7 running at 4GHz and with 6 GB of memory. PP CS4 is loaded on one HD and the video from the camera is copied to a second HD.

I don't know if I am filming in 720p. The camera is a Panasonic AG-HMC70 and it has three settings for video quality:
HF = 13 Mbps - Constant Bit Rate
HN = 9 Mbps - Variable Bit Rate
HE = 6 Mbps - Variable Bit Rate
I have been using the HN or middle quality setting. Anybody know if this is 720p or something else?

Need help finding the right codec to play QT files

Like many others who have posted, all the quicktime files on my drive have turned to black. Previously when I opened the file, I saw picture and sound. Now every single file has only audio, but the picture is black.
I am operation on Mac O.S. 10.4.11. I am using Quicktime Pro 7.5. I have been trying to fix this problem for a month now. Many people have suggested I need to find the right codec, but so far I have not found it. I have tried: A52codec.component, AC3codec, MacOS 8.x, 9.1.x, Apple Intermediate Codec.com, Apple MPEG2.codec.component, Avilmporter-r7.component, DivX Decoder.component, DivX Encoder.component, DivX Pro 6.8.0.19 + keymaker, EnsharpEncoderMacOsX.cmg, Fbx 20091quicktime_macemu.pkg.tar, Fbx QT.pkg, Flipsformac, WMV Advanced.component, Flipsformac WMV Advanced Exports.component, Flipsformac WMV Import.component, IMXCodec.component, LAAME Universal Installer.mpkg, LAAMEncoder.component, QSSP_2.1.dmg, QSXEssentials.component, QSXEssentials.dmg, QTFvx.component, Red Quicktime Codec v3.1.pkg, Red Code iedcod.qt.component, Spectrograph.component, TSCC.component xiphqt.component, XviD_codec-r58.component, XviDELEGATE.component
Nothing worked!
I also tried to install Perian. This did not work.
What should I do? Should I re-install my operating system and start over? About a month ago, all the video clips played just fine. Is there any solution?
Thanks

Hi Wangerer!
I haven't even heard of half of those! You may have reached overkill on codecs!
Get rid of some of them and read this:
These are the downloads and the settings you need in order to view/hear pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!
It is known to work in the great majority of cases with Safari 3.0.4, 3.1, 3.1.1, QT 7.3, 7.4.x and 7.5 and OS 10.4.11.
Assuming you already run Tiger versions OS 10.4.11 and have Quicktime 7.4 or above, and are using Safari 2 or 3, download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
RealPlayer 11 (which is no longer in beta) for Mac from:
http://www.versiontracker.com/dyn/moreinfo/macosx/15540
Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs.
Adobe FlashPlayer should first be uninstalled using the appropriate uninstaller available here:
http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157&sliceId=2
and then the latest version obtained from here:
http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash
and installed.
(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS, but please see my footnote if you are running Leopard.)
In earlier versions than QT 7.1.3 in Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).
You should also ensure, if you are running Tiger 10.4.11, that you have downloaded and installed all the correct version for your Mac of Security Updates up to and including 2008-004. (N.B. Security Updates require both a restart and a permission repair.)
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them). However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/divx/mac/
Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them) to enable Java.
Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz, and that you have selected 'Built in Audio'.
Important: Now repair permissions and restart.
You should also consider having the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.
There is an additional 'fix' you could try if you are having problems with Flash and Quicktime, depending on which type of Mac you have:
On Intel Macs, make sure that you are not running Safari in Rosetta. You can check this, and change it, in the Get Info window.
On PPC Macs, go to the Hard Disk/Library/Internet Plug-Ins folder, and drag the file 'QuickTime Plugin.webplugin' to the desktop. Quit and restart Safari. If things have improved you can trash that file. If they haven't put it back, as the lack of this plug-in can cause QT content in some widgets to cease functioning.
And now there is an additional kid on the block: SilverLight. Microsoft has created their own version of what a replacement for Flash should be. You can read more about it here:
http://silverlight.net/
So, if you go to any sites that have been designed for this new Silverlight stuff, you can download the plug-in from here (but make certain that you are downloading SilverLight v.1.0 for OS X (10.4.8 upwards):
http://silverlight.net/GetStarted/
FOOTNOTE
If you are running Leopard:
Some users have mentioned that the latest Flash Player (v.9.0.115.0) conflicts with Leopard, and that they have needed to revert to v. 9.0.47. This can be downloaded from here:
http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14266&sliceId=1

Query don't use the right index when using bind variables

Hi people !
I need some help because I have an issue with a query that don t use the right Indexes as it should
First of all, I have mainly three tables :
ORDER : Table that contains description for each Order (approximately 1 000 000 Records)
ORDER_MVTS : Table that contains the tasks made (called movements) to set up each Orders
with quantity of packages prepared for each product (approximately 10 000 000 Records)
PRODUCT : Tables that contains the products (approximately 50 000 Records)
When I launch the query with hard coded values, it brings back response very fast
because it uses the right index (ORDER_DHR_VALID) which represent the date and hour of the order
(with format 'DD/MM/YYYY HH24:MI:SS'). The selectivity for this index is good.
NB 1: I have to use the trick " >= Trunc(date) and < trunc(date) +1 " to filter on a simple date because
the index contains hour and minutes (I know it wasn't probably a bright idea at conception time).
NB 2: The index on ORDER_MVTS.PRODUCT_CODE is'nt discriminating enough because there is'nt enough different products.
It's the same for index on CUSTOMER_CODE and on MVT_TYPE so only the index on ORDER.DHR_VALID is good.
Here is the correct explain plan when I execute the query with hard coded values :
SELECT SUM(ORDER_MVTS.NB_PACKAGE)
FROM ORDER_MVTS, PRODUCT, ORDER
WHERE ORDER.DHR_VALID >= TRUNC(to_date('14/11/2008 10:04:56','DD/MM/YYYY HH24:MI:SS'))
AND ORDER.DHR_VALID < TRUNC(to_date('14/11/2008 10:04:56','DD/MM/YYYY HH24:MI:SS')) + 1
AND ORDER_MVTS.MVT_TYPE = 'DELIVERY'
AND PRODUCT.CODE = ORDER_MVTS.PRODUCT_CODE
AND ORDER_MVTS.ORDER_CODE = ORDER.CODE
AND ORDER.CUSTOMER_CODE = 'ADIDAS'
AND PRODUCT.CODE = 1234
Rows Row Source Operation
1 SORT AGGREGATE
2 NESTED LOOPS
4 NESTED LOOPS
2 INDEX UNIQUE SCAN (object id 378548) --> PRODUCT_PK
4 TABLE ACCESS BY INDEX ROWID ORDER
777 INDEX RANGE SCAN (object id 378119) --> ORDER_DHR_VALID
2 TABLE ACCESS BY INDEX ROWID ORDER_MVTS
30 INDEX RANGE SCAN (object id 377784) --> ORDER_MVTS_ORDER_FK
Now the problem is when the query is used in a Cursor with bind variables.
It seems like Oracle don't use index on ORDER.DHR_VALID because he can't figure out that he have
to actually filter on a short period of time (only one day).
So Oracle uses the index on ORDER_MVTS.PRODUCT_CODE which is'nt a bright idea (it takes 10 secondes instead of just one)
Here is the bad explain plan :
Rows Row Source Operation
1 SORT AGGREGATE
2 NESTED LOOPS
722 NESTED LOOPS
2 INDEX UNIQUE SCAN (object id 378548) --> PRODUCT_PK
722 TABLE ACCESS BY INDEX ROWID ORDER_MVTS
1790 INDEX RANGE SCAN (object id 377777) --> ORDER_MVTS_PRODUCT_FK
2 TABLE ACCESS BY INDEX ROWID ORDER
1442 INDEX UNIQUE SCAN (object id 378439) --> ORDER_PK
Now I have found two solutions to this problem :
1) using a Hint to force the use of index on ORDER.DHR_VALID (with /*+ INDEX(ORDER ORDER_DHR_VALID) */ )
2) Using Dynamic SQL and keeping the date hard coded (but not the other values except mvt_type)
For example :
QUERY :=
'SELECT SUM(ORDER_MVTS.NB_PACKAGE)
FROM ORDER_MVTS, PRODUCT, ORDER
WHERE ORDER.DHR_VALID >= TRUNC(TO_DATE('''||To_char(P_DTE_VAL,'DD/MM/YYYY')||''',''DD/MM/YYYY'')) '||
AND ORDER.DHR_VALID < TRUNC(TO_DATE('''||To_char(P_DTE_VAL,'DD/MM/YYYY')||''',''DD/MM/YYYY'')) + 1 '||
AND ORDER_MVTS.MVT_TYPE = 'DELIVERY'
AND PRODUCT.CODE = ORDER_MVTS.PRODUCT_CODE
AND ORDER_MVTS.ORDER_CODE = ORDER.CODE
AND ORDER.CUSTOMER_CODE = :CUSTOMER
AND PRODUCT.CODE = :CODE ';
These two solutions work but Number 1 is bad in theory because it uses a Hint
and Number 2 may be difficult to code.
So my question is : Does someone knows another solution to force the use of index ORDER_DHR_VALID that can be simple and reliable.
Thank you very much for support

What version of oracle you have? CBO work is different in 9i and 10g.
Usually cost based optimizer do not want to use index for >< condition with binding variables because optimizer can not use statistic to determine selectivity, and by default selectivity of <> operators is low.
(As I remember '>' selectivity by default is 5%, you have two conditions > and <, therefore resulting selectivity will be 0.05*0.05=0.0025 as two independent events, but selectivity of other conditions
ORDER_MVTS.MVT_TYPE = 'DELIVERY' or ORDER.CUSTOMER_CODE = 'ADIDAS' looks much better for CBO)
The best solution I see is do not use binding variables. Actually your query looks as searching query, which executes not so often, therefore you will not have perfomance win along of skipping execution plan creation.

I was on facebook and deleted an icon by using the right-click menu but then all my pictures and all profile pictures, could no longer be seen. I was able to view them in Explorer so this is something I did in Firefox. How can I unblock a site?'

'''I was on facebook and deleted an icon by using the right-click menu but then all my pictures and all profile pictures, could no longer be seen. I was able to view them in Explorer so this is something I did in Firefox. How can I unblock a site?'''

If you select that right-click context menu entry then you block all images from that domain and not one specific image, so do not use that.
* Check the exceptions in Tools > Options > Content: Load Images > Exceptions (e.g. sphotos.ak.fbcdn.net)
You can use these steps to check if images are blocked:
* Open the web page that has the images missing in a browser tab.
* Click the website favicon ([[Site Identity Button]]) on the left end of the location bar.
* Click the "More Information" button to open the "Page Info" window with the Security tab selected (also accessible via "Tools > Page Info").
* Go to the <i>Media</i> tab of the "Tools > Page Info" window.
* Select the first image link and scroll down through the list with the Down arrow key.
* If an image in the list is grayed and there is a check-mark in the box "<i>Block Images from...</i>" then remove that mark to unblock the images from that domain.

After using the right mouseclick safari doesn't respond to any mouseclick

Hi since updating to safari 5.1.1 after using the right mouse click safari doesn't respond to any mouseclick anymore. I can use the keyboard and select menus but that is it. Reinstalled Safari, resetted safari and removed all preferences, caches and disabled all extensions etc. nothing helped. Any suggestions here?
Im using snow leopard, on a dual core mac Intel xeon desktop.

Solved it finally after a long time.. I was triggered that another user on the same system did not have the problem I scanned my user library folder: The problem was an old safari extender plugin in my Contextual Menu Items folder. After removal all is working again :-)

How to always rotate objects around the same point, even using the right-click menu?

I need some of my objects to always rotate around the same point. How can I select a point which will stay that way?
Using the rotate tool resets after deselecting.
Also, I'd like to rotate objects around a certain point even when using the right click > Transform > Rotate.
Is it possible?

Right, so this is where Illustrator falls short with respect you your need, but only in the sense that the reference point can't be made to stick. You can, however, use Smart Guides to make it so the point is easy to set at exactly the same location, (especially since your object has an anchor point there), manually before each rotation.

Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

I cannot use the right colors for a web image.

I cannot use the right colors for a web image. Photoshop CC keeps replacing colors because my colors are "out of color space for print" or something like that (I hope I translated it right - I work with PS Dutch version and this forum is only in English).
I am not interested in printing at all. I do not want any adaption for printing! I only want the right color on screen for a web image.
I changed the color settings many times, I created my image all over again, but Photoshop keeps replacing my vivid red by pale pink because of print colors.
Thanks for your help.

Use SRGB color space. and in the color picker when you see the warning don't click on the warning to have it fix the issue. As that will change the color you want want to use.

I suggest you buy your memory from OWC or DataMem. Both guarantee the memory works or will replace it if it does not, no questions asked, within their 30 day return period. I've used both for over 20 years, and no complaints.

(made a mistkae on the stats of index B)

I assume the execution path is a nested loop driving of the table with the constant inputs.
The key difference in the stats is that the second index has a blevel of 2. I'd guess that the cost of using the first index is 1, and the cost of using the second index is three.
The basic cost of accessing a table through an index is:
blevel +
index selectivity (ix_sel) * leaf blocks +
table selectivity (ix_sel_with_filtering) * clustering_factor.
However, if the blevel is 1, then Oracle ignores it.
Your index and table selectivities in both cases are 1/distinct_keys (since this is 10.2)
The numbers involved with the leaf block and clustering factor calculations are so small (and similar) that the difference of 2 in the add-on for the blevel is the deciding factor.
According to the statistics, though, the choice of index shouldn't make much difference to the performance, since the number of rows (and blocks) visited is likely to be the same. However, if you have an uneven distribution of values for individual columns, you may need a histogram on that column so that the optimizer can see the effect it has on the expected work.

MacBook denying pw acces when starting up, by definitely using the right passwort.

Hey guy's I got a problem since yesterday. After my MacBook have been on stand by and went down causing low battery, the acces by using the right pw is denied.
Nothing works to get into it. The MacBook is still on stand by.
Someone out there having the same problem? Or am I the first one? ;-)

Dreained it to the state of sleep nd then waited for the sleep light to go off.
A couple of hours passed after that when I returned to my desk and plugged in the adapter.
