Video Performance On 2009 Mini Before And After Snow Leopard
When I ran Leopard on my 2009 Mac Mini, I could watch full screen video on one of my two monitors while surfing the web on the other. It wasn't flawless, I could see some latency issues, but it was entirely tolerable. With Snow Leopard, the full screen video openly stutters, and frames are being dropped like mad. Unless a future update improves this, I've basically lost the ability to watch video on a second monitor and surf the net at the same time.
If you have not done since upgrading to Snow Leopard, run Disk Utility and use +Repair Disk Permissions+.
As a test, create a new admin user account in System Preferences Accounts pane
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8235.html
Log out and log in to the new account. In the new account, you will be using default Snow Leopard user preference settings, and only standard background processes are running (unless you installed third-party software that runs at the system level). Try doing the video thing that worked before, to see if there is any improvement.
If it works better, there is something in your normal account that is conflicting with how Snow Leopard operates. You can focus your trouble-shooting there to figure out what it is.
If it is the same, the problem is likely to be at the system level. Hopefully, the first update will help. In the mean time, if you happen to have an external drive that you can erase, you might try a fresh installation there and boot from it, to see if that makes a difference. Alternately, you can, of course, back up your data, erase your internal drive, install Snow Leopard, and restore your data.

Video "zooms" before and after transition
My video zooms a little before and after the cross dissolve transition. I tried deleting the render files and re-rendering but the noticeable zoom is still there.
Video is 1920x1080 60i prores @ 17.1mbps. Project is same settings, with field dominance set to none. I export to quicktime self contained. Video looks great except for the sudden zoom before and after the transition.
Any thoughts?danwayfilms wrote:
Always Use Best Quality when rendering movies: unchecked
Not really sure this is the culprit but it should be checked.
Also, what is that field dominance thing? You said it was originally set to "none" but you're dealing with interlaced footage and upper field dominance.

Count before and after to certain occurance.
I am trying to count the amount of units studied before and after a certain Course was taken.
So ID 1 did PREP in 2013 in the first period and has and also had done a unit in 2009 so reult be before prerp count 1
ID 2 did PREP in 2012 first period and also an OTHER course in the same period as well as a OTHER in period 2. So when a PREP course appear in the same period and year as an OTHER course I would like it to count it as AFTER Prep.(see below(so when equal count as after PREP))
ID 3 has done one unit before before PREP which is in 2011 and 2 Units after the first PREP course.
I attepted this with not in and in statments basic I know but to no luck.
Any help is greatly appreciated.
Thanks

New to FCPX on a project this weekend. I have gotten reasonably comfortable with the basic features but one thing that I CANNOT figure out, is how (what used to be) selecting a track in the timeline to activate it to apply a transition. I need to select a video clip which stands alone in the stack which is positioned above the primary track and add a blend transition before and after the clip. I have set the opacity to blend with the images in the primary track below but the beginning and end of the clip in the second stack do not fall at the transition points in the lower track which should not matter anyway. I can’t find it in Help or the third party tutorials that I purchased and completed. Thanks for your help!
Tom gave you the answer. As a follow-on you can then use the Cross Dissolve transition on your newly converted connected clip. This transition will allow it to dissolve smoothly into the video below it. Note that the Fade to Black transition will take both that clip and the video below it to black which would probably be undesirable. Use Cross Dissolve instead. Best wishes.

Everyone: This time repair your permissions before and after 10.4.8 update
Hello All,
Just a reminder for all those who are updating to OS 10.4.8.
While many people do ignore all the recommendations that we provide and still come through fine, please do consider observing the following to minimize your problems.
To insure the best chance of success, please consider downloading the Combo Updater for your computer instead of using Software update.
For PowerPC Mac's, this would be:
http://www.apple.com/support/downloads/macosx1048comboupdateppc.html
For Intel Macs, this would be:
http://www.apple.com/support/downloads/macosx1048comboupdateintel.html
The benefit of using the Combo Updater, is that it replaces all system files that have been changed since the last major release (in this case since 10.4.0).
So, if you have any system files that have become corrupted, the Combo Updater will very likely over-write those, and spare you the headaches that come from updating an operating system that has problems that just haven't come to the surface yet.
In many cases, you can have problems that have not come to the surface, and the "Delta" or Software update method will bring them out to bite you. The reason for this, is because the Delta / Software Update version only changes files that have changed since 10.4.7. And, it works more in a "patch" fashion. So, if there is a problem in one of the files being patched, then the update will cause you some major headaches.
Going with the larger "Combo" update over-writes almost all the System files with clean versions instead of just making patches. So, it is frequently much more successful.
Now, with that said, before you update, you should make sure your permissions are all set properly. If your permissions are wrong, then your update will likely have trouble.
So, go into "Disk Utility" in the Applications --> Utilities folder and repair your permissions.
Start by selecting your hard drive on the left window of Disk Utility. Then, go down and click on the "Repair Permissions" button. Once it's completed, then exit Disk Utility.
Now, it is also extremely important to make sure all running programs are closed before you install any system update. So, go ahead and restart your computer.
Restarting will make sure that all programs are closed, and that nothing weird is stuck in memory before you install.
If you have anti-virus programs running, then disable or deactivate them first (you don't want them interpreting this as unauthorized modification or it might prevent certain files from being updated).
Now, with your computer freshly restarted, install the Combo updater you downloaded.
When prompted, click on the "Restart" button when prompted.
Now, the computer will startup, but sit at the spinning wheel for several minutes. It will eventually restart again on it's own. And, finally, it will start-up all the way and you'll be back at your desktop.
Now, immediately go back to Disk Utility and repair permissions as you did in the previous step. You will likely see several permissions that have been repaired. In my case, I had dozens of CoreAudio, Widgets, and other permissions that needed repair. Once permissions have been repaired, go ahead and restart one last time. This makes sure that everything is set and then cleaned-up.
Once it reboots, begin using it and enjoy.
Now, this may sound like a lot. But, it really is simple. It just reads like a lot of stuff.
And, of course, you are free to ignore this and just install it however you like. Many people have their own ideas here. And, many people say you don't have to do anything to prepare. But, for those that have had huge problems in the past, these extra steps will usually save you the major headaches that tons of people inevitably have with every new update.
Anyway, I hope this helps to save at least a few of you any problems. If you don't agree with the ideas above, just ignore it and do as you like.
But, if you want a little extra piece-of-mind and a better chance at success, then please consider exercising this extra caution.
And, for the record, I have updated my machines to 10.4.8 (within minutes of the update being available) and it is working perfectly smooth on my systems.
I hope you find this helpful.mhunter, thanks and good that you take the time and effort again to remind everyone that it does take an effort to do a major OS update, to ensure maximum stability.
So far my 10.4.8 Update is a-okay, and I have had many trouble-free updates since installing 10.4
I too practice rigourously and "religiously" before and after an OS or Security Update, but I normally use Software Update, equally successful:
1. Before Startup, UNPLUG all external devices, left only keyboard, mouse and internet connection, unless they are all wireless.
2. Startup, disable NAV if any, Repair Disk Permission. Restart again, Repair Permission again.
3. Do Software Update
4. Restart, Repair Permission
5. Shutdown, plug everything back
6. Startup Mac, use Mac
So far these steps have been keeping all my macs both at home and at work very very stable and healthy.
Maybe, just maybe if everyone here, all mac users were to follow these steps, yes they can be a hassle, yes they can take up some time, but then there will be less less complains and "blasts" at Apple, just because perhaps themselves have been too careless or negligance in performing updates.

Plastic Surgery Before and Afters... best program?
Hi guys,
I am brand new to graphic designing or anything related to it!
I'm currently looking to do side by side before and after pictures for my office. Sometimes the pictures differ in color or contrast or need to be cropped. Sometimes a patient requests that their eyes or a tattoo be hidden (with black bars).
What program(s) would you guys suggest? Photoshop? Illustrator? Other programs??
I just got a brand new Mac so please help me!
PS. PSdesigner= plastic surgery designerBe aware that a there is a difference between a video that consists of a slideshow, and what DVDs consider a slideshow.
If you want a DVD slideshow, then I suggest taking a look at one of the Lord of the Rings Extended Release DVDs. On the two extra discs with each movie there are plenty of DVD slideshows. With a DVD slideshow you can go forward or back through the slideshow. You can stay on any slide as long as you like. A slide can contain audio. Audio cannot carry over from one slide to another. There is no transitions from one slide to another.
What I suspect is that you want a video that acts like a slideshow. In that case, do not use the slideshows in DVD SP at all. Create your video outside of DVD SP, then just place it in a Track and treat it as any other video.
That being said, do you want a lot of control over how the video slideshow is created, or do you want a program that will do most of the work for you at the expense of not having absolute control over how things are put together? If you want full control then create your video slideshow in FCP/Motion. If you want a program that will do a lot of the work for you, then you should look into iPhoto. It can create some pretty spectacular slideshows very easily, but you will not have the full control you have with FCP. -
I am finding when I bring up images that were previously in LR2 that in the bottom right hand corner there is an (!). When I click on it it asks if I want to update my image. Then come up a before and after image. I cannot for the life of me get back to just having a single image. Thanks anyone.
Adobe has a Lightroom video titled "What's New in Lightroom 3" at http://tv.adobe.com/watch/getting-started-with-adobe-photoshop-lightroom-3/whats-new-in-li ghtroom-3/
If you watch it you will see a detailed explanation of the ! symbol at about 6:27. I went ahead and converted all of my images so they could all take advantage of the new Develop features.

Triggers before and after update
Hi
I would like to add triggers before and after update for the following code. I would be thankful if someone give some guidance
update per_all_people_f a
set start_date = (select min(effective_start_date)
from per_all_people_f a1
where a1.person_id = a.person_id)
where person_id in (1114,115);Thanks
annaHi
I was unable to answer you. I agree with Peter . Also i want to add
that in HRMS you should check what triggers are already on that table and be carefull with creating your own one. With your own trigger you can influence on some application logic you know.
( And i hope that is a table first of all :) - but as i know _F at the end of table name means table )

PSC 1210 page feed before and after printing
My PSC 1210 has been working fine for years but it has just recently started feeding a blank page before and after printing. That wouldn't be a problem except that the blank pages are not fully ejected, this means that I have to grab the first blank page, as it comes through the printer, and pull it out, otherwise it gets drawn back in causing a paper jam when the actual print job starts. Once this blank page has been removed the print job continues perfectly.
This occurs when printing documents, copying using the scanner, and printing a test page.
I have removed and reinstalled the printer driver/software and performed a partial reset on the printer, neither fixed the problem.I see you mention that the issue also happens when you are copying, that means that this issue is not related to your printer software. So that's good to know!
Now, since this is not a software issue, this must then be related to your hardware. Is this printer plugged into a wall outlet directly or is it plugged into a surge protector? To be sure that the printer gets all the power it needs make sure that it is plugged directly into a wall outlet.
First things first, I would recommend unplugging the printer for about 30 seconds from both the back of the unit and from the wall outlet, and then plugging it back in. Try making a copy or print and see if the issue persists.
You can also try cleaning the paper feed rollers in the printer, here is a document that can show you where all of those are located and how to clean them.

Counting values before and after an interval
I posted this awhile back but I'm back to trying to solve the problem (didn't solve it), so apologies if that is bad etiquette! This forum has been so helpful though I thought I would try again:
design/methodology question
The short of it is I have a table with calls that happened, all have a start and end time.
I want to take 1 min intervals over a given hour (say, 12-1pm) and (the part I need help with) count all calls that happened before and after that interval.
That is to say, all calls that were 'active' during that interval (consider if I call started at 11:59 am and ended at 12:05) would need to be counted for the 12:00, 12:01, 12:02, 12:03, 12:04, and 12:05 intervals.
So what I'm trying to construct is an SQL query that uses a 'variable' in this case (I think).
That is, so I can saw 'where start_time < min_interval' and where 'end_time is > min_interval' and count those records to my total.
But I'm at a loss on how to pull this off!
Thoughts?If a call began at 15:01:01 and ended at 15:01:59, was it active at 15:01? Was it active at 15:02? Both? Neither?Is only active at 15:01.
Do you need 4 separate numbers, or do you need 1 number, which is the total of these 4?I need 1 number which is the math formula (using the number above)
1 + 2 - 3 + 4

Something like this:

to_char(new_time(trunc(end_time, 'hh24') + (trunc(to_char(end_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi') > minute_interval

How to make an before and after effects?
So, I want to make a video that show the audience this is before and after the edit. And i want to make it look like this YouTube Rewind 2014: Behind the Scenes - YouTube
How to make it?
Thanks:)Really? You take footage of you shooting the video with another camera then you edit it together with shots of the finished project. If you want to show before and after shots of an effect you just put the original footage on top and animate a mask or opacity to reveal the rendered effect below.
If you can't figure out how to make a before and after then you will have a very difficult time doing any effects using AE because there is absolutely nothing in this before and after but very basic editing and masking. -
How much is iPhone before and after taxes?
how much is iPhone before and after taxes? I am from the Philippines and I am just wondering buying it online with my credit card. i know that it costs $399 for 8GB and $499 for 16GB.
I bought mine day one, so the pricing isn't the same anymore.
As for the one your Aunt buys, she will pay either $399 or $499, depending on model, plus applicable CA sales tax, which I do not know.
Keep in mind that you will not be able to activate your phone in the Philippines in its virgin state. Keep in mind as well that currently there isn't a good way to "devirginize" a 1.1.3 iphone. -
Why there is implicit commit before and after executing DDL Statements
Hi Guys,
Please let me know why there is implicit commit before and after executing DDL Statements ?

The reason is that it makes no sense to update the structure of the database whilst there is outstanding data updates that have not been committed.
Imagine having a column that is VARCHAR2(50) that currently only has data that is up to 20 characters in size.
Someone (person A) decides that it would make sense to alter the table and reduce the size of the column to varchar2(20) instead.
Before they do that, someone else (person B) has inserted data that is 30 characters in size, but not yet committed it.
As far as person B is concerned that insert statement has been successful as they received no error, and they are continuing on with their process until they reach a suitable point to commit.
Person A then attempts to alter the database to make it varchar2(20).
If the database allowed that to happen then the column would be varchar2(20) and the uncommitted data would no longer fit, even though the insert was successful. When is Person B going to find out about this? It would be wrong to tell them when they try and commit, because all their transactions were successful, so why should a commit fail.
In this case, because it's two different people, then the database will recognise there is uncommitted transactions on that table and not let person B alter it.
If it was just one person doing both things in the same session, then the data would be automatically committed, the alter statement executed and the person informed that they can't alter the database because there is (now) data exceeding the size they want to set it to.
It makes perfect sense to have the database in a data consistent state before any alterations are made to it, hence why a commit is issued beforehand.
Here's something I wrote the other day on the subject...
DDL's issue a commit before carrying out the actual action
As long as the DDL is syntactically ok (i.e. the parser is happy with it) then the commit is issued, even if the actual DDL cannot be executed for another reason.
Example...
We have a table with some data in it...
SQL> create table xtest as select rownum rn from dual;
Table created.
SQL> select * from xtest;
RN
1We then delete the data but don't commit (demonstrated by the fact we can roll it back)
SQL> delete from xtest;
1 row deleted.
SQL> select * from xtest;
no rows selected
SQL> rollback;
Rollback complete.
SQL> select * from xtest;
RN
1
SQL> delete from xtest;
1 row deleted.
SQL> select * from xtest;
no rows selectedSo now our data is deleted, but not committed, what if we issue a DDL that is syntactically incorrect...
SQL> alter tab xtest blah;
alter tab xtest blah
ERROR at line 1:
ORA-00940: invalid ALTER command
SQL> rollback;
Rollback complete.
SQL> select * from xtest;
RN
1... the data can still be rolled back. This is because the parser was not happy with the syntax of the DDL statement.
So let's delete the data again, without committing it, and issue a DDL that is syntactically correct, but cannot execute for another reason (i.e. the database object it refers to doesn't exist)...
SQL> delete from xtest;
1 row deleted.
SQL> select * from xtest;
no rows selected
SQL> truncate table bob;
truncate table bob
ERROR at line 1:
ORA-00942: table or view does not exist
SQL> rollback;
Rollback complete.
SQL> select * from xtest;
no rows selectedSo, there we have it. Just because the statement was syntactically correct, the deletion of the data was committed, even though the DDL couldn't be performed.
This makes sense really, because if we are planning on altering the definition of the database where the data is stored, it can only really take place if the database is in a state where the data is where it should be rather than being in limbo. For example, imagine the confusion if you updated some data on a column and then altered that columns datatype to be a different size e.g. reducing a varchar2 column from 50 character down to 20 characters. If you had data that you'd just updated to larger than 20 characters whereas previously there wasn't, then the alter table command would not know about it, would alter the column size and then the data wouldn't be valid to fit whereas the update statement at the time didn't fail.
Example...
We have a table that only allows 20 characters in a column. If we try and insert more into that column we get an error for our insert statement as expected...
SQL> create table xtest (x varchar2(20));
Table created.
SQL> insert into xtest values ('012345678901234567890123456789');
insert into xtest values ('012345678901234567890123456789')
ERROR at line 1:
ORA-12899: value too large for column "SCOTT"."XTEST"."X" (actual: 30, maximum: 20)Now if our table allowed more characters our insert statement is successful. As far as our "application" goes we believe, nay, we have been told by the database, we have successfully inserted our data...
SQL> alter table xtest modify (x varchar2(50));
Table altered.
SQL> insert into xtest values ('012345678901234567890123456789');
1 row created.Now if we tried to alter our database column back to 20 characters and it didn't automatically commit the data beforehand then it would be happy to alter the column, but then when the data was committed it wouldn't fit. However the database has already told us that the data was inserted, so it can't go back on that now.
Instead we can see that the data is committed first because the alter command returns an error telling us that the data in the table is too big, and also we cannot rollback the insert after the attempted alter statement...
SQL> alter table xtest modify (x varchar2(20));
alter table xtest modify (x varchar2(20))
ERROR at line 1:
ORA-01441: cannot decrease column length because some value is too big
SQL> rollback;
Rollback complete.
SQL> select * from xtest;
X
012345678901234567890123456789
SQL>Obviously, because a commit statement is for the existing session, if we had tried to alter the table column from another session we would have got
SQL> alter table xtest modify (x varchar2(20));
alter table xtest modify (x varchar2(20))
ERROR at line 1:
ORA-00054: resource busy and acquire with NOWAIT specified
SQL>... which is basically saying that we can't alter the table because someone else is using it and they haven't committed their data yet.
Once the other session has committed the data we get the expected error...
ORA-01441: cannot decrease column length because some value is too bigHope that explains it -
I am trying to delete pages I have crated in numbers, but can only see them in print preview. Without print preview I do not see them. How can I delete these pages, but keep others before and after?
Hi Crushed,
Numbers doesn't have pages. It has a canvas that holds objects such as tables and charts.
Drag the objects from the bottom of the canvas onto the white space above. That will reduce the number of "pages" (sheets of paper) that will print.
Regards,
Ian.
