Is FCP really non-linear?

Discreet Edit was a true NLE program. Within a time line you could manipulate the speed of a clip, and the rest of the video in the time line would not be messed with. Because when you manipulated that individual clip, it would simply speed up or slow down what material was available in the original source clip.
Final cut, when you manipulate the speed of a clip, every part of the project on the time line just after that clip is thrown out of EVERYTHING.
In future upgrades of FCP I hope that they adopt something that allows us to manipulate clips more freely in a truly NLE environment instead of having to open up a second time line , manipulate the clips there, and then bring them back onto the original time line.

"In digital video editing, non-linear editing is a method that allows you to access any frame in a digital video clip regardless of sequence in the clip"
- http://www.webopedia.com/TERM/N/nonlinearediting.html
"In video, a non-linear editing system (NLE) is a video editing (NLVE) or audio editing (NLAE) system which can perform random access on the source material."
- en.wikipedia.org/wiki/Nonlinearediting
"TRUE" non-linear editing has nothing to do with speed changes. As you can see defined above, it is the allowance of random access to the footage. The speed change capabilities of ONE non-linear application doesn't mean that it is a TRUE non-linear editor. It means that it deals with one aspect of non-linear editing in a way you deem superior. It is fine to think of that as a better way of doing a speed change, but to then use that ONE thing to say that that system is a TRUE non-linear editor, and that everything else PALES in comparison is ludicrous.

Magic Moves not always Magic (non-linear slide orders)

Magic Moves opens the possibility of non-linear slide orders with animated transitions. Previously in keynote (KN '08), as far as I could ascertain, this was impossible. Now a slide with several hyper-linked objects can enjoy an animation of the on screen objects to there new positions, where-ever they may be on the on the linked slides.
Unfortunately, as in some other things Keynote, it seems flakey. While it works most of the time for some reason, even when duplicating the linking slide and repositioning the very same objects, the Move is delayed and instantaneous: decidedly not Magic!
The joy of being able to finally make the fully interactive Keynote presentation that will slide objects the right amount automatically according to there destination slide seems possible. The great thing is I don't have to construct all the different moves linking 26 different pages to each other via various routes (8 links on each page, which happened to be 8x26 possible linking routes = 208 move builds: too much for prescriptive build/move animations).
But if I can't get it too work 100% I can't really show my client. Any know issues with this Magic Move stuff?
I can replicate problem but not predict when it won't work or decode what is triggering the problem. Searching forum only revealed comment the Magic Move is work in progress. Note I am not scaling any objects. Can upload if it helps. Part of the original Presentation with a linear narrative can be seen at:
http://www.vimeo.com/3018559
Essentially I am endeavouring to make all the images 'clickable' so the film strip glides (against the preset order) to become the centre project. Also like to add a left and right button. All this can be theoretically done with invisible rect's with hyperlinks and Magic moves on each slide.
Thanks for reading though all this – hope it's clearer than mud.

Thanks for the response, Kyn.
As it happens writing that long explanation, I thought I'd look from another angle and returned to the file – finding the answer straight away.
Conclusion:
Hyperlinks never use Magic Move transition, even if it is selected transition for the slide. I was getting hoodwinked by the fact that when I had forward and back arrows with hyperlinks to other slides, those slides were before and after the current slide. So they were Magic Moving with a mouse click on the Hyperlink, but only when forward one slide or backward one slide. Any other linking distance failed to Magic Move.
I've already made the feature request but *please second it*, this would be a very powerful feature. Think Non-Linear Presentations and Info Kiosks with seamless transitions. And interaction is an area Powerpoint has decided edge on Keynote so it can and needs to be closed! (PP is such a trial of an interface after KN).

New to Final Cut Pro, but not to Non Linear Editing

Hi my name is Rob and I am going to be a new Final Cut Pro owner here shortly. I have worked with various other Non Linear editing systems like SONY Vegas, AVID and Adobe Premiere Pro. So I am not new to the Non Linear style of editing video.
I got my first glimpse of FCP at my internship and loved it. Now my dream of owning a MAC and FCP are coming true.
I will be purchasing a Mac Pro with...
- One 2.8GHZ Quad-Core Intel Xeon Processor
- 2GB (2x1GB) RAM
- 500GB 7200-rpm Serial ATA 3Gb/s Harddrive
- ATI Radeon HD 2600 XT 256MB Videocard
- Apple Cinema Display (20" flat panel), upgrading later to another 20".
And as you all know I will be getting Final Cut Pro with this purchase as well.
I just thought I would introduce myself to this part of the forum. As I will probably be here all the time. I have purchased the FCP 6 manual to get myself started.

You can call me Rob or S70 or heck even S. LOL, I would like Rob, but whatever.
I am a news editor. I edit Packages sometimes, but mainly VO's, SOT's, NATVO's the normal TV stuff. I edit with Adobe Premiere Pro at work and work from DVC PRO, BETA and even from our DVD archives and of course news wires.
I do not shoot. I may do my own shooting of random stuff, with the help of an old Digital MiniDV JVC camcorder.
I'd like to try and get my FCP skills up and maybe start freelancing and maybe even getting into my own production company or something like that.

Asset Lease accounting -non Linear lease payment

We are currently having a business scenario where an asset is acquired on capital lease basis.
Different depreciation area is maintained for leasing to account for interest on leasing.
The payments are made in monthly for lease payment.
The lease payment amount changes every year.
The lease tab in asset calculates Net present value on the basis on lease payment entered in the leasing tab.
Now since the lease payment varies every year the net present value calculation will be different(not as calculated in asset master -leasing tab).
I am not aware if the asset module can take care of any non-linear payment scenario to calculate the NPV and interest accordingly.
Example an asset ABC is acquired as capital/finance lease basis on
monthly lease payment for 4 years as follows:
The said asset is to be capitalized with net present value and we also need to ensure that interest calculation is done accordingly.
1st year 1000/month
2nd year 2000/month
3rd year 1500/month
4th year 1900/month
Since in lease tab only single lease payment can be entered, how the different monthly lease payment can be entered so as to calculate correct NPV.
Next how the correct interest calculation and net present value can be calculated correctly.
If any one has come across such situation, please reply.
Regards,
Manish Garg

Hi ,
SAp 4.7 does not support non linear lease payment. Only the Equal lease instalment can be generated automatically when you will go for opening balance at the leasing tab of the display assets(AS03).
But the ECC6.0 support the change over the lease instalment,

No non-linear under voice-port to reslove hissing on NM-HDV

Hello.
I have a trouble with 2MFT on NM-HDV.
I can hear hissing on call.
So, i had configured no non-linear under voice-port, then i can't hear any hissing.
Instead, I can hear echo on call.
How can i fix it?
Regard,
john.

Hell Venky.
Thnak you for your helping.
I tried to configure based on the web site what did you told me.
But i couldn't success it to resolve echo issue.
The voice gate have 12.4(1a) on Cisco 2851.
So the solution to reslove echo doesn't fit in my case.
As i mentioned, normally i can hear noise each i talk another persion. If i stop the conversation i can't hear noise. but i started to talk again, i can hear noise each time.
Thus i tried to disable "no non-linear" parameter, i can hear echo instead noise.
So i should choice if i can hear noise or echo.
And also, i tried to change input gain and output attenuation from -6 to 14, but the each still can hear.
out voip network toplolog is below.
NEC Digital Phone---NEC PBX---Gateway---(cat6500---MSPP(WAN Area)---cat6500)---Gateway---NEC Digital Phone.
If i make a call using Normal Phone (INot Digital Phone), I can't hear noise. Whenever i can hear noise with NEC Digital Phone.
Here is the option on cisco 2851 with 12.4
2851(config-voiceport)#?
Voice-port configuration commands:
bearer-cap Specify the bear capability
busyout Configure busyout trigger event & procedure
comfort-noise Use fill-silence option
compand-type The companding type for this voice port
connection Specify Trunking Parameters
cptone Configure voice call progress tone locale
default Set a command to its defaults
description Description of what this port is connected to
disc_pi_off close voice path when disconnect with PI received
echo-cancel Echo-cancellation option
exit Exit from voice-port configuration mode
idle-detection Idle code detection for digital voice
input Configure input gain for voice
music-threshold Threshold for Music on Hold
no Negate a command or set its defaults

output Configure output attenuation for voice
playout-delay Configure voice playout delay buffer
shutdown Take voice-port offline
threshold Threshold [noise] for voice port

Non-linear moves in Ken Burns effects

Pans and zooms tend to ramp up in speed. This doesn't happen all the time, but enough that it is a problem. Anyone else dealing with this?

this is not a bug, but a feature of iMHD... ;-))
to be serious, iM Grandmaster Karl Petersen had mention this often in this forum and gave some alert to Apple... because, in many cases, a non-linear movement look much better, in some absolutely not...- so, there should be some check-box.-
only workaround so far: make the movement and the time a little longer; cut off the unwanted exaleration..- :-/

How to implement non linear navigation Date LOV

Hi,
I have a requirement like I need to show non linear combo LOV in my UI which allows the user to navigate to next or previous item in the list.
Any help on this or do we have any inbuilt design pattern for this component.
I am using Jdev 11.1.1.7.0.
Many thanks in advance.
Regards,
Dileep.

Hi Frank,
Thank you so much for your reply. Sorry, I am not able to attach that component image here.
Actually it looks like normal combo box LOV, additionally it has two navigation icons both the sides (both left and right hand side) of combo box and allow the user to navigate to previous or next item in the list of values available in the combo box.
I am not sure whether it is fusion specific custom component or adf component. Any help on this?
Many thanks in advance.

Dileep.

Non-linear animations? (Flash CC)

Hello there!
I am getting crazy since 2 hours ago. Motion Editor is gone (WHY?!?!??!?!) in Flash CC and I don't know how to set a non-linear speed between two keyframes (see attachment) anymore. I don't want the speed constant, but I want to decide its acceleration or deceleration. I just used a preset here to show you
Thanks x(

Hi All,
Flash Pro CC 2014 (v 14.0.0.110) is now available for download via the Creative Cloud App.
We have included an all new Motion Editor along with several other new features with this release of Flash Pro. The new Motion Editor is completely redesigned, intuitive and easy to use while preserving the core functionalities and backward compatibility with Flash CS6
To Invoke the Motion Editor, simply Double-Click on your Motion Tween span on Timeline (or Right-Click and select 'Refine Motion') and the Motion Editor opens up in-context in the Timeline itself. Double-Click again to collapse once you have made your adjustments.
Complete list of New features in Flash Pro CC 2014 is available at these links:

Lens Distortion Non-linear Distortion and Perspective Distortion

Hello everyone, I'm a member of the vision team in the Intelligent Ground Vehicle team in Cal State Northridge, an autonomous robot that uses real time feed and laser data as sensors.
So we need a fully undistorted video feed for us to do image analysis with the lowest processing time.
We have a distortion situation with our current vision system where we have to fix Non-linear Distortion due to the use of a wide lens ( About 144 Deg ) and also Perspective Distortion of the projected image. The camera is mounted on top of our robot with an angle with the ground (about 45 Deg).
I have been using labview for about 6 months, and have been trying to correct this distortion using Vision Assistant program to generate VI's.
First I'll list my attempts here and then I will direct some questions.
First attempt, a picture of a dot grid was taken with our camera and that picture was correct by Vision Assistant's nonlinear image calibration. Then a VI was generated by Vision Assistant, and we changed in the input from images to video.
This method worked but not accurately.
Second attempt, we tried to remap the image pixels using a correction function generated through Excel, this method did not work accurately either. I'm not even sure how to do this again since it was done in the past.
So my questions are here:
1) what's the best approach to correct the distortion in our camera? and how please.
2) what are we doing wrong/right in general?
3) Generally, how would I improve any vision VI to reach faster processing times?
Everyone's help is very much appreciated,
Omar

I'd like to correct the information provided by Bruce. It was correct up til Vision Development Module 2010. You need to update, Bruce ;-)
In Vision Development Module 2011, we improved the accuracy and precision of our grid calibration, by computing a lens distortion model (Division or Polynomial Model), that take into account radial and tangential non-linear distortion of the lens. The new algorithm also allows to compute the internal parameters of the lens (focal length and optical center), that you can use to determine the relationship of the camera to the object under inspection.
The microplane algorithm that Bruce described is still availale, as it can be used to solve applications in which the object you're trying to calibrate is non planar, and can be calibrated by wrapping the grid around the object.
A calibration will be valid for a specific perspective plane, and will need to be recomputed if the camera moves or object is in a different plane.
Typically, the calibration process is an offline process. For performance reasons, you don't necessarily want to correct the entire image (although VDM provides you with that function). As Bruce mentioned, most algorithms, like edge detection, pattern matching etc, return their data both in pixels and real-word data, talking into account the calibration information that you learned. For the few algorithms that only provide pixel results, you can use VIs to convert Pixels to Real-World. This operation is fast.
What type of features are you trying to measure in the image? Can it be solved in 2D, or do you need 3D information? How many cameras do you have on the robot?

Question about DBMS_PREDICTIVE_ANALYTICS and non-linear data

Hi,
I am executing DBMS_PREDICTIVE_ANALYTICS against some data, but it's not giving me good predictions for my null data. Should I be using different data mining techniques ?
The data has the following fields 1) Position, 2) Odds, 3) Selection & 4) Event.
Position and Odds and linear, since the smaller the number the higher the likelihood of winning, but Selection is a lookup based on a Name, so therefore non-linear, but can be used to look at previous form in the same data set. Event is a way to group Selection's into an Event.
What's the best way to tackle this ?

Sorry for delay, been on vacation.
I'm trying to improve odds for predicting winners, given the form, odds, previous history, and form of other runners in the race.
Take a look at data.betfair.com for a list of data elements available to me.
I'm currently using the data where the latest_taken column has the highest value. i.e. the odds and ranking just before the race starts.

Correcting non-linear colour distortions

Hi,
I'm wondering if it's possible to automatically correct non-linear colour distortions using the standard Photoshop tools (preferably CS2 or earlier)?
The standard grey-point in the "levels" dialog box only works with uniform casts, such as you'd get if you took a photo with a coloured filter over the lens. This doesn't work if the distortion is non-linear (e.g. shadows are bluish and highlights neutral or yellowish).
What I'd *like* to be able to do is select an object I know to be grey in real life- such as a statue- with as wide a range of tones/brightness levels as possible, and have it automatically alter the curves for the whole image such that this statue's highlights, midpoints and shadows are all roughly grey.
Using "Match Color" doesn't work here becaue it alters saturation levels to match as well- so if I use a desaturated version of my image as a guide (with only the grey statue selected), the original image is entirely desaturated to match. I don't want this- I simply want the curves adjusted so that things that are meant to be grey *are* grey (regardless of brightness) and other objects are their natural colour and saturation.
While I can theoretically play around with the curves manually, this is tedious and fiddly and is like trying to wrestle a snake(!) as fixing one part often upsets another, and it's very difficult to get things to look natural.
Is this doable? Any ideas would be appreciated- thank you,
- AN

Thank you, but that's pretty much what I've been doing already when I mentioned adjusting the curves by hand.
To show what I mean here's a "good" image:-
Note that the dark bumpers and the light silver body are both neutral grey. Now, take a look at this version I've modified to illustrate the problem by altering the shape of the red channel's curve:-
Note that while the dark bumper has a reddish hue to it, the silver car body has a cyan tint. Now, load this into Photoshop and try removing the cast(s) by using the grey-point tool.
If you set it by choosing the reddish-cast bumper as the target, the light areas become even more cyan. If we click on the cyan-cast car body, the bumper goes even more red. Now you see the problem, I hope :-/
As I said before- yes, I know it's theoretically possible to fix this by playing with the curves for each channel. But that's nowhere near as easy as it sounds, particularly if you don't know what the distortion to the response curves were in the first place.
Ideally what we want to do is either to either (a) be able to set *multiple* grey points for objects at different levels, or (b) select areas that are supposed to be approximately grey. Then let Photoshop figure out the adjustments necessary.
Or is there another way to do it?

Keynote non-linear scale in line graph

I'm trying to teach kids how to do line graphs and it doesn't help that Keynote treats the horizontal axis like it's a bar graph... even when you want a line graph. It takes the data points and spaces them evenly which can give you a non-linear scale. This is one of the classic mistakes kids make. Grapher can do it correctly but that's one more step.
Any way to make it behave properly?
aedan
iMac G4 800, PowerBook G4 12, loads of older ones. Mac OS X (10.4.5) The SE/30 is the king of compacts.

Keynote's graphing capabilities are relatively rudimentary, especially with regards to more technical needs. As far as I know, Keynote always treats X-axis labels categorically (it doesn't understand numeric values), and thus will always evenly space the datapoints.

Universe.applyOverload Method Run non-linearly slower and slower

Universe.applyOverload Method Run non-linearly slower and slower, that is, for the 10th user and restriction we add, this method runs 1 second, however, for the 80th user and restriction we add, this method runs 8 seconds.
Customers think it's a bug for our BOE Java SDK method, could I know why this method is non-linear, and any way to improve its running speed.
The following is the code, for interator 80 times.
while (iter.hasNext())
                    user = (rpt_users_t) iter.next();
                    IOverload overload = (IOverload) newObjs.add("Overload");
                    overload.setTitle(user.getBoezh().trim());
                    overload.setUniverse(universe.getID());
                    overload.setConnection(connectionID);
                    overload.getRestrictedRows().clear();
                    overload.getRestrictedRows().add("HZB0101_T","HZB0101_T.BRANCH_COMPANY_CODE='3090100' AND HZB0101_T.DEPARTMENT_CODE='"+ user.getBmdm() + "'");
                    overload.getRestrictedRows().add("BM_T","BM_T.DEPARTMENT_GROUP_CODE='" + user.getBmzdm().trim()+ "'");
                    infoStore.commit(newObjs);
                    // Commit to User
                    IInfoObject everyone = (IInfoObject) infoStore.query(
                              "Select TOP 1 SI_ID " + " From CI_SYSTEMOBJECTS "+ " Where SI_KIND='User' " + " And SI_NAME='"+ user.getBoezh().trim() + "'").get(0);
                    int everyoneID = everyone.getID();
                    universe.applyOverload(overload, everyoneID, true);
                    //infoStore.commit(objs);
                    System.out.println(user.getBoezh() + " loading...");

When invoking applyOverload multiple times, it's O(N^2) if you're granting rights to a User or UserGroup.
When granting, the applyOverload method retrieves all Overloads applied to the Universe and walks across each one, granting the identified ones and removing rights from others.
Sincerely,
Ted Ueda
