Question about Slow Motion and Running Times

I am using iMovie '08 to help my boss make a video of the pump and suction cup assembly he has created. He asked me if I knew how to slow it down to a frame by frame type of shot. He also asked if there is any way to have a running time on the video both in real time and the slow motion shot. Can anyone help me?
At work I am using a Mac Pro with 4 G of RAM and 2x2.8 GHz Quad-Core Intel processor.

iMovie 08 was primarily designed for SIMPLE editing.
iMovie 06 is a free download to iLife 08 owners. (THEY WANT YOU TO HAVE IT!)
Much has been written about the differences between iMovie 06 and iMovie 08. I have found the below link to be helpful.

Questions about slow motion recording on the iPhone 6 Plus

I took a couple of slo mo videos and they look cool, but there are a few things I don't understand.
The frame rate I took them at is 240 fps.
In an online article, I read the slow down speed is just 1/4th. But if the regular frame rate is 30 fps isn't the slow down 1/8th? I think that is true, because a video in the "recent" album says "8 seconds" but actually plays back at 64 seconds, which is 1/8th speed. And it's 64 seconds long after I upload it to YouTube.
One question is whether there is an easy way to see the actual playback time other than doing the math?
Another question is I understand there is supposed to be some way of editing the videos so you can adjust which parts are slowed down and which parts aren't. I can see how to trim, and I see the narrowly spaced bars (normal speed) and widely spaced bars (slow speed) but I don't see any way of adjusting those.
Any hints about this? Or other slo mo recording any editing hints?
Thanks,
doug

End result after talking with AppleCare.
1. Yes, if you record at 240 fps it is 1/8th speed.
2. There is no way in either Photos or iMovie on the iPhone to see the playback time! Just the time it took to record the video.
Doesn't it seem that people would want to know the playback time of a video?
I have submitted feedback.
I figured out how to edit the spacing of the real-time vs slo-mo portions. So that's no problem. But there is no way of knowing what the playback time is other than editing it on your computer or uploading it to YouTube or some place like that and see the result. Or manually timing it I guess.

Question about video cards and render times

I would like to know if having a REAL video card (not a GeForce with a measly 64 megs of RAM), would help with the rendering times in iDVD? I prefer to use the High Quality settings, so rendering is taking a very long time. Would a card with more video RAM help this along any faster? Thanks in advance.

I would be surprised, if the grafic card (=display) is involved in the process of encoding a videoDVD... (???) this a computational task =>CPU, main system...
factors for encoding speed are:
* CPU (G3/4/5/dual/quad/Intel)
* RAM (… as much as your wallet allows...)
* speed of harddrive..
* other tasks... best practise: let encoding the only main task...
* lots of free space on internal drive (iDVD needs at last 10 - 15GB free); trying to create a videoDVD with letssay 3GB free adds hours of encoding time

Java compile and run time questions

Hello, I have two generic question about java compile and run:
1. When I used javac to compile my project, it complained some classes can't be found. I added the jar file which contains these needed classes to the jre/lib/ext/ directory. The compiler no longer complains. But I'm confused. I thought the jar files in jre/lib/ext/ only used for java run time, not the compile time. Can someone help me to explain this?
2. If I need certain user defined jar file in the classpath to compile my application, does that imply that I have to have that jar file if I want to run my project?
Thanks in advance.

1. lib/ext is used for generally finding classes, it doesn't matter whether you are compiling or running.
2. Yes, you will.

Slow motion and speedup during a single clip

Is there a way to take a single clip, and slow down portions of the clip, while speeding up other portions of the clip.
Is there a way to adjust playback speed using keyframes I guess is my basic question, so the start of the clip is slow motion, then the middle is played back at an accelerated or normal rate, then the end of the clip becomes slow motion again.
-Roger

Yes, is the short answer. Using the time remapping feature in the "effects" panel (top center of the screen, second tab from the left) you can set certain portions of the clip to play back at normal speed, then slow it down in certain sections, and then speed it back up. You can also cut the clip using the razor tool (in the tools panel at bottom right of the screen) and just reduce the speed of that section of the clip. The downside to using the time remapping (if my memory serves me - don't take my word for it) is that you lose audio, but the transitions from normal to slow-mo and back are much smoother. Using the razor tool, you simply place the timeline indicator where you would like to begin the slow motion segment, then cut the clip with the razor tool, the repeat the process where you want the slow-mo section to end. Then, select the section that you want to play back in slow motion, and reduce the speed. This is the method that was used before the time remapping feature was available. The transitions are not at smooth, but you can keep audio for the sections where the speed isn't modified. Just be sure to select the "ripple edit" check box when you modify the speed/duration setting of the clip (right click the video clip to get the speed/duration setting dialog box).

Big-Oh Notation,algorithm-analysis and running time - aagh headache!

Hey folks,
I was reading about the Big-Oh Notation, algorithm-analysis and running time.
Now, it's all probably very nice - if you get to understand it. Which I don't! Gives me headache! lol
And we're having an exam soon. Hmm. Could someone please help to explain it a bit better please?
Oh and by the way, one of the examples mention something about T(N), which I presume is running time for the size of a problem.
So it said:
"? Running time of a loop =
time taken by the body statement * size of the loop
? Example
for ( i = 1; i <= N; i ++)
c = c + 1;
? body statement takes O(1), the size of the loop is N
? So, this loop has running time T(N) = N * O(1) = O (N).
? More precise ?
? i = 1 takes 1 time unit
? Body statement takes 2 time units
? i <= N takes 1 time unit, i ++ takes 1 time unit
? Totally T (N) = 1 + 1 * (N +1) + 2 * N + 1 * N = 4N + 2 = O(N)
init condition body update
Nested loops
? Nested loops: Analyze them inside out
time take by body statement of innermost loop *
product of the size of all the loops
? Example:
line 1 for ( i = 1; i <= N; i ++)
line 2 for ( j = 1; j <= N; j ++)
line 3 k++;
? line 3 is the body statement in the innermost loop (for-j): takes
O(1).
? size of for-j: N
? size of for-i: N
? So the running time for this nested loops: N*N*O(1) = O(N2 )"
Please help me! I don't understand much of this.
Best Wishes!

Ok. I'll have a look about it - but the question I
had was... like...
what exactly is it that takes N steps? How do I know
what takes O(1) steps
and N steps?Depends on what you're doing. Example: adding an item to a linked list of N elements will always take the same effort: attach it to the end. Whether the list already has 0, 10 or 1000 elements doesn't matter. O(1).
If you want to try and find the maximum value in an array of numbers, you need to look at each number in there. So an array with 1 number takes one look, an array with 100 numbers needs 100 looks and an array with N members needs N looks. O(N).
Does the parametres themselves take a step each? How
many steps does the body (as far as I've understood
it, it's c = c + 1; which is the body) take? And how
long time does it take?That body takes only one step. The question is whether you want to account for the repetition or not. If you don't, it's O(1) . There is no N to take into account. If you count in the repetitions too, you end up with an N - the number of times you call the body. So the effort O to run the body once is O(1), the effort to run it N times using the loop is O(N). It really depends on what the actual action is you want to look at.

A question about item "type and release" of source system creation

Hello expert,
I have a question about item "type and release" of source system creation.
As we know,when we create a web servie source system,there will display a pop-up which includes three items as "logical system","source system"and "type and release".
About the item "type and release",when we push "F4" button,there will be three default selections as below:
"ORA 115     Oracle Applications 11i
TLF 205     Tealeaf 2.05B
XPD 020     SAP xPD".
Who can tell me when and how should I use the three selections.
And also I attempted to input the item by some optional letters except the default three selections and it seems that I can input it freely.
Thank you and Best Regards,
Maggie

Hello DMK,
Thank you very much for your answer.It is very helpful for me.
Can I ask you further about it?
I got that it is a semantic description item.
You said the default selections are set by our basis people.Would you like to tell me how should we creat a new value except the default ones for item "type and release"?Only by inputing the value in the item directly?But you see we canot see the new value item we created by ourself when we push "F4" button next time ,is that ok?Or do we have to ask basis people to define one new value item just like the default seletions before we use it.
Also if possible would you like to describe detail about "This becomes important when you are troubleshooting certain issues especially when RFC connection problems."
Thank you and Best Regards,
Maggie

How to best achieve slow motion and fast motion

Hi - I am new to the forum and a basic user of Premiere Pro CS5. I am working on a project shot at 24 fps, and would like to do slow and fast motion.
From what i understand there are 2-3 different ways to do this in Premiere - choosing speed/duration of the clip from timeline, or choosing time remapping form effects panel ot using rate stretch tool. Wondering how do these compare and which is better - any pointers for this will be great help. Also is slow motion and fast motion better done in After Effects than Premiere. Or any recommended plugins that would work on cs5 and cs5.5. Thanks.

The main difference between using time-remapping and just using time-stretching is that time-remapping allows you to change the speed quite flexibly at different times in the same clip, whereas stretching just changes the rate for the whole clip.
See this page:
"Change speed and duration for one or more clips"
> Also is slow motion and fast motion better done in After Effects than Premiere.
After Effects has far more control, especially with regard to how new image information is created between the original frames when you change speed and require frame interpolation (frame blending). Pixel Motion and Timewarp use a very advanced motion vector method (based on the Foundry's Kronos software) for doing this.
See "Time-stretching and time-remapping".

Slow motion and Normal speed?

Can I take video shot 720p at 60 fps and use both slow motion and normal speeds in the same video??

Time Stretch is where I would start. If you need to apply that Effect to only part of a Clip, just use the Razor/Scissors Tool, to Cut that Clip, into the segments, where you wish to apply Time Stretch.
Posterize Time can be effective, as well, but from my reading of your needs, I think that Time Stretch (Rt-click the Clip, or Clip segment and apply).
Good luck,
Hunt

MBP 17" Battery Capacity and Run Times : Survey

I've had 2 MBP 17's so far, and I'd like to get a general idea from everyone about their battery capacity and run times they are experiencing.
My first MBP17 had a Full Charge Capacity of ~5900mAh before calibration and PMU reset, and 6800mAh after. This translated to about 3:40 of run time under light load.
My current MBP17 had a Full Charge Capacity of ~5899mAh before calibration and PMU reset, and 6942mAh after (currently). This translates to about 3:48 of runtime....still trying to get some more real-world run time numbers under different loads.
This proves to me that it is quite critical to calibrate your battery and reset your PMU at least once to ensure that your battery is reporting it's correct capacity. I'd be interested to know what everyone else's batteries are reporting.

A few questions about the ka790gx and dka790gx

i have a few questions about the ka790gx and dka790gx , how much better is the dka790gx compaired to the ka790gx ? . how much difference does the ACC function make to overclocking etc , i plan on getting a phenom II 940BE or 720BE . i already have the ka790gx so would it be worth building another system using the dka790gx mobo , or should i keep what i already have and just change the cpu ?

It's largely irrelevant what other boards had VRM issues other than the KA790GX - the fact is it died at stock settings. Since there is little cost difference between the more robust DKA790GX (or Platinum if you really need 1394) why bother with the proven weakling? There are other examples around of the KA not having a robust power section. There's no way I would use even a 95W TDP CPU in the KA and absolutely not O/C.....!
As for the credentials of Custom PC, I have generally found their reviews accurate and balanced, and echo my own findings where applicable. If a little too infrequent.
The fact that the KA has such a huge VRM heatsink leads me to my other comments on the Forum, particularly regarding the "fudge" aspect:
"""Henry is spot on - the notion that adding a heatsink to the top of the D2PAK or whatever MOSFETS is effective is virtually worthless. The device's die thermal junction is the tab on the device back - which is always against the PCB pad. The majority of heat is therefore dissipated in to the board, and the fact that the epoxy plastic encapsulation gets hot is simply due to the inability of the heat to be conducted away from the device die via the tab. Not sure when Epoxy become an effective conductor of heat.... Good practice is to increase the size of the PCB pad (or "land" in American) such that the enlarged PCB copper area acts as an adequate heatsink. This is still not as effective as clamping a power device tab to an actual piece of ali or copper, but since the devices used are SMD devices, this is not possible. However, the surface area required to provide sufficient PCB copper area to act as a heatsink for several devices isn't available in the current motherboard layouts. Where industrial SBC designs differ in this respect is to place the VRM MOSFETs on the back of the PCB on very enlarged PCB pads - where real estate for components is not an issue.
Gigabyte's UD3 2oz copper mainboards sound like a good idea, on the face of it. However, without knowing how they have connected the device tabs to where and what remains a mystery. I suspect it is more hype than solution, although there will be some positive effect. From an electrical perspective, having lower resistance connecting whatever to whatever (probably just a 0V plane) is no bad thing.
The way the likes of ASUS sort of get round the problem is to increase the sheer number of MOSFET devices and effectively spread the heat dissipation over a larger physical area. This works to a degree, there is the same amount of heat being dissipated, but over several more square inches. The other advantage of this is that each leg of the VRM circuit passes less current and therefore localised heat is reduced. Remember that as well as absolute peak operating temperature causing reduced component life, thermal cycling stresses the mechanical aspects of components (die wire bonds for example) as well as the solder joints on the board. Keeping components at a relatively constant temperature, even if this is high (but within operating temperature limits), is a means of promoting longevity.
For myself, the first thing I do with a seperate VRM heatsink is take it off and use a quiet fan to blow air on to the VRM area of the PCB - this is where the heat is. This has the added benefit of actively cooling the inductors and capacitors too....
Cooling the epoxy component body is a fudge. If the epoxy (and thus any heatsink plonked on top of it) is running at 60C, the component die is way above that.....
It's better than nothing, but only just."""

Question About Color's and Gradients

Hi all,
I have a question about color swatches and gradients.
I am curious to know, if I have 2 color swatches that I make into a gradient color, is it posible to change the tint of each indivdual color in that gradient and have that applied to the gradient without having to adjust the gradients opacity.
The reason that I'm asking this is because in creating a project I found that the colors that I chose for to make my gradient from my swatches were to dark, and while I can adjust each one's tint to my liking (if the object they were applied to was going to be a solid color) but that doesn't seem to apply to the overall gradient.
I hope that makes sense, I know that this was something that was able to be accomplished in quark and was wondering if I can do something similar.

If you double click your gradient swatch (after adding it to the swatches)
Then click a colour stop in the gradient, and then change the drop down menu to CMYK (or rgb)
And you can alter the percentages there. It's not much use for spot colours but it's a start.
But making tint swatches would be a good start anyway.
At least then when you double click the gradient (in the swatches) to edit it you can choose from CMYK, RGB, LAB, or Swatches and adjust each colour stop to your liking.

Question about clear page and reset pagination

Hi,
I have a question about clear pages and the reset pagination in an URL. What is the reason why a clear page doesn't also trigger a reset pagination on the pages which are cleared?
I can't really imagine a business case where it makes sense to clear all data of page items on a page and don't reset the pagination of reports on that page which probably use a page item in there where clause...
The drawback of this behavior is that a developer always has to set the reset pagination checkbox when he clears the target page and the even bigger drawback is that if you specify other pages to clear, you can't reset pagination for them, because reset pagination only works for the target page.
Thanks for your input.

The question about portlet customization and synchronization

I have a question about portlet customization and synchronization.
When I call
NameValuePersonalizationObject data = (NameValuePersonalizationObject) PortletRendererUtil.getEditData(portletRenderRequest);
portletRenderRequest.setPortletTitle(str);
portletRenderRequest.putString(aKey, aValue);
PortletRendererUtil.submitEditData(portletRenderRequest, data);
Should I make any synchronization myself (use "synchronized" blocks or something else) or this procedure is made thread-safe on the level of the Portal API?

HI Dimitry,
I dont think you have to synchronize the block. i guess the code is synchronized internally.
