Motion 5: Setting constant speed on position change

Hi there,
Can anyone shed some light on how to get rid of the smooth movement setting when moving an object from A to B. Motion appears to accelerate and decelerate the object to make it look smoother. However, I want to set an object to move at the set speed straight away, not accelerate up to it.
Thanks in advance

This is for Mo4, not Mo5, but I assume the same thing holds. The default keyfame setting is Bezier. If you right click on the position keyframe and select linear, it should do what you want.

Unable to set custom speed to motion path on Camera

This is a followup question to "Controlling speed along motion paths"
(Many thanks to Mark Spencer and specialcase for the their excellent insights getting me this far =)
After experimenting with motion paths and realizing they were indeed what I was looking for, I set up my project so that the camera would follow specific paths along 2d images. Everything worked perfectly until I tried to modify the speed along which the camera travels along those paths.
In the motion path, in the speed drop down menu, I can select Constant, Ease in etc.... all the way to Custom, but they work slightly differently than I expected: while before (ie. applying motion curves to objects as opposed to the camera) I was able to getting a diagonal line in the Keyframe Editor where I could modify keyframes using bezier curves to adjust the speed, now, choosing the various speed options appears to change the "Transform.Position.X" and "Transform.Position.Y" curves directly.
When I select "Custom", "Motion path" and Custom Speed" appear in the keyframe menu above the Camera drop down, but its curve appears only as a dotted, completely horizontal line in the graphing window. The "Transform.Position.X" and "Transform.Position.Y" curves also revert to horizontal dotted lines. If I try to add curves to the custom speed line, the X and Y curves remain horizontal and the camera does not move.
Is there some reason I cannot get custom speeds for cameras without losing my motion path data?
Is there some way to work around this?
Thanks again for all of your help,
Tim

I'm not sure if there is some setting I have wrong:
When I try this, while I am able to set keyframes, the motion path data is reset. (ie. the Transform X and Transform Y curves reset to 0).
In the Keyframe Editor, I can make new curves for the X and Y values and for Timing, but the camera does not follow the motion path, it follows the new x and y curves. Trying to get those curves to match the motion path exactly is a large hassle.
This might help:
If I apply the motion path to an shape rather than to the camera, everything works perfectly (the object moves along the motion path, and I am able to set keyframes for the Custom Speed curve with no problems whatsoever). If I then copy the motion path directly from the shape and paste it to the camera layer, the path appears as a red curve (as it should), but the camera does not move.
Is there some way I can upload the motion file so that you can see what exactly is going on?
Thanks again,
Tim

Slow motion (constant speed) rendering problem. ATTENTION PROs!

I have tried almost everything to try and fix my problem and now I am going insane!
I am editing a short promo featuring constant speed adjustments and video filters. When I render the video seems to drop frames and jutter. Why is this when i have only reduced the speed of the clips by 50% or 75% ? ?
I have put it through compressor several times and printed the video onto DVD to see if the problem lies within any other program, but i believe my problem is with final Cut HD.
The footage is HDV interlaced. I have made sure the frame blending options are checked although this makes no difference and have rendered it I dont know how many time.
Do I need to bring the original rushes out of the bin and adjust the speed again from scratch...essentially start again?
HELP! I am going mad!
Mac Book Pro (2ghz intel / 2gb memory) Mac OS X (10.4.9) Final Cut Studio HD

I have done it!
I firstly made a quicktime movie, using current settings, to create a single HDV clip. I then created a new sequence, titled HDV, and opened up the sequence settings. Going into the video processing tab I changed field dominance to 'upper odd' and motion to 'best'. I then dropped the new HDV clip into the timeline. At this point I sent this new clip to Compressor and chose the 'best quality 90min 16/9', MPEG 2 two pass + Dolby. EXPORT....HAPPY DAYS! The results are great. Perhaps I could make it better by stopping the footage down to SD first?

Buttons set as "free position" change back to default

In iDVD 6, if you move a button to free position and then save it, when you re-open the project the button position changes back to the default position. I am using the iDVD 6 theme "Reflection Black" and positioned the button in the gray pane at the bottom but it moves back up the pane to the default position no matter how I try to save it. Anyone else having this problem?
Thanks

The first six slideshows behave themselves and stay where I position them in the area designed for the listing. The remaining six are off to the side right across the moving drop zones, which makes them hard to read.
I believe all of the menus are defaulted to handle six buttons, while you can add up to twelve on some, maybe this main menu can only "hold" six... I had four on mine.
How about one button on the main menu that says something like "Slideshows" and when you click on that it takes you to a new menu (the chapter menu) and try to put twelve there.

Constant Speed + Timing not working

Hi,
I have two clips that are in the same group. I've created a motion path whereas the clips are pulled from left to right across the canvas. The 2 clips are a panormic still image that has been stiched in PS.
I've set the timing speed to "Constant Speed" but when I replay the clip the speed is not constant and it seems like the motion "fades" in at the start and "fades" out at the end.
Thanks in advance.

hi,
it sounds like there is an amount of easing in and out of the motion path. two things you can do, navigate to the keyframes window, select the keyframes and set the interpolation to linear. Or dont use a motion path and simply apply a Throw behaviour, or set your own keyframes.

Ken Burns Effect - Variable vs. Constant Speed

On a test slideshow I worked on in iPhoto, I noticed that the Ken Burns effect uses a "variable" motion. Meaning if I'm utilizing the zoom effect, it'll start out slow, then speed up, then slow down again for each photo. However, I just want a constant speed zoom for each photo.
Is there away to have the Ken Burns effect zoom (and/or pan) with a constant speed?

100 brownie points to Terrabay! LOL
For those that don't know how Terrabay arrived at his solution: iMovie DOES let you dictate how long your transition (for ANY transition) is when you put it into your show. When you press editing and go into transitions drag the transition you want into your time line - you can adjust how long you want it to be and which direction you want it to go before you put it in your show, and if youve already put it in but want to lengthen/shorten it, just click on your transition in the time line, make the change and press UPDATE. Simple.

My motor runs at a constant speed

i have a
PCI 7342 controller.
MID 7654/7652 servo motor drive
motion control software
motion assistant 1.1.
I have setup the hardware connection.
When I try to run the motor using the motion assistant the motor runs at a constant speed irrespective of the velocity that I specify in the motion assistant.My motor velocity is 7 voltage per 1000RPM.The motor keeps running at a constant voltage of 25volts.I donot have a encoder but I have a tachometer.
pls help.

Hello Sumitha,
In order to use servo motors with National Instruments motion controllers, you must have some form of position feedback. This is required due to the PID control loop implemented on the controller. Without some kind of control loop, there is no way to guarantee that the motor will get to the commanded position following the specified trajectory. Servo Tune is a tool used to adjust the PID parameters, which in turn control the stability of your system.
If you do not have any way of adding position feedback (such as a quadrature encoder), you will not be able to make full use of your motion controller. It is possible to simply read a voltage in and output a specified voltage from the motion controller. However, you lose all hardware timed control and all the benefits of a motion controller. If you are interested in that option, a DAQ board might work better for you. Otherwise, I highly recommend looking into adding a quadrature encoder to your system.

DC motor - constant speed

I 'm a light user of Labview and need some assistance.
My objective is to make the dc motor retain constant speed even when a load is applied.
The tools I have to acquire data with are:
NI USB-6211
Labview 8.2
Optical Encoder - 1000 pulses per revolution
My main concern is writing the PWM VI to do this.
My first guess is to set use a DAQ assistance to acquire a signal as a counter input from the encoder.
Not really sure what to do with that because I am kinda lost from there.
How would I use that info to adjust the PWM of the output signal?
All help is appreciated.

Hi jgarcia,
this doesn't work at all. Your application requires closed loop control. This means you need deterministic behavior (= stable timing of the control loop) for single point I/O operations. With your setup this is not possible due to the fact, that both the USB and Windows introduce a lot of jitter (using a PCI DAQ device would make things a bit better, but you still couldn't get reliable control behavior on a Windows operating system). For a control system reliable timing is at least as important as proper tuning of the control parameters.
For motion control tasks it's much better to use a device like the PCI-7342, that runs all control operations in a realtime environment onboard. Other options include using a realtime operating system and PCI or PXI DAQ hardware or a cRIO-System with drive interface modules. For a single-axis system, the PCI-7342 is probably the most cost-efficient solution.
Sorry for the negative answer, but with your current hard- and software setup you will could easily waste a lot of time on a poor solution.
Kind regards,

Position change clarification

we have one derived business update type DBT_E001 and one update type SAM3010 (commission payment) in cash flow IFRS report, but these two are not appeared in "assign update type to position change category", is this correct?
regarding to position change category, pls find attached.
what does "post negative purchase value" 1010 mean? for MM1100+, it is used in borrowing of a fixed term deposit.
in SE2000, it is incoming payment, which is payment inflow, why it is position outflow? what does position inflow mean?
should we assign update type interest payment in position change category?

Dear, Jolin.
I suggest you not to change anything in configuration "Set the effectsof the update types on the position components" as it already configured for all simple and standart processes.
If you want to uderstand how it could help you - play with configuration in sandbox.
In order to know what Position Change Category does - see this table TRLTS_PMCAT. There you can find:
Position change category - which you assign to update type.
Two components - which can be changed by Position change category
Rules - that tell you what components are changed and how.
Discription and other fields.
As concerns update type DBT_E001 ans similar Derived business transactions update types - you won't see any configuration as position change category is predefined - see the table above - position change category E001.
in SE2000, it is incoming payment, which is payment inflow, why it is position outflow? what does position inflow mean?
Incoming payment means - money inflow because you sell your security. Position outflow means - your security is sold
what does "post negative purchase value" 1010 mean? for MM1100+, it is used in borrowing of a fixed term deposit.
negative means you owe somebody. somebody gave you money and you have to return it some day.
positive means you gave somebody money.

Bug: Front Panel objects relative position change when placing merge VI onto Block Diagram

Hi Jim,
After my previous post, I also saw this behavior, so I decided to do another test. If there are no decorations in the VI set to “Merge VI” (“Place VI Contents” for LabVIEW 8.5 and later) the controls and indicators are still not selected when dropping the VI from the Functions palette. I checked this behavior back to LabVIEW 7.1 and it is consistent throughout that controls and indicators are not selected. (Consequently, so is the fact that when decorations are present they don’t maintain the relative position).
I am not sure if this would be better suited as a CAR or product suggestion since it has been this way that long, but it does not appear to be related to the fact that decorations are present in the Merge VI. It does seem strange that the decorations are selected though. Looks like the best way to work around this is to drop the VI from the Controls palette. Hopefully, it’s not too much of a hassle.
Hi Donovan,
Thanks for checking in.

This just means that not many people use this feature. However, now that VIPM Professional makes it so easy to edit the palettes, I'm sure that others will start complaining that this doesn't work as they expect.
> I am not sure if this would be better suited as a CAR or product suggestion
since it has been this way that long, but it does not appear to be
related to the fact that decorations are present in the Merge VI.
Just look up the functional specifications for this feature and see if all objects are supposed to be selected.
But seriously, is there a reason that only the FP decorations are selected? Surely this would be documented somewhere, if there was a good reason for this current (IMO, buggy) behavior.
> It

the best way to work around this is to drop the VI from the Controls
palette. Hopefully, it’s not too much of a hassle.
That's not a reasonably work-around, IMO. It doesn't make sense to drop Block Diagram components onto the Front Panel. For example, this bug affects the JKI State Machine. It doesn't make sense to drop a State Machine onto the Front Panel.
So, I'd file it as a CAR/bug, and then wait to see how LV R&D feels about it. If they can find some valid reason for why Controls and Indicators shouldn't be selected, then that's fine (and hopefully someone will explain it to me).
Thanks,

Is limiting network speed by setting adapter speed good? [SOLVED: yes]

i have an arch NAT router PC which has 3 network adapters present; "external" for my cable modem interface, "internal" for an internal subnet 172.16.0.0/16, and "wifi" which is a separate internal subnet 192.168.192.0/24 open wifi that I recently setup for guests and the like. the open wifi is explicitly barred access to the 172 network with iptables. i currently have a 50mbps down/10mbps up comcast internet connection. i have been limiting the open wifi's speed by setting the NIC designated for it to 10 mbps, just so that all of my bandwidth isn't completely eaten up. this appears to work completely fine; realistic speed is measured to around 8mbps throughput, which I consider fine for basic internet access.
i'm just curious whether this is an appropriate method to restrict bandwidth speed? i've read about something called "qdisc" which could limit speeds within iptables, is this a better way to accomplish this?

Luckily you are in the position of having a whole link that you want a hard limit on.
tc is more for traffic control between source and destination of packets going over the same link, or dynamic stuff. However, it will never be as trusted as a link set to a slower bit rate, and can be a pain to manage/T-Shoot.
Over the WAN traffic control is normally done with switching protocols like ATM and MPLS. However, even on large networks clients may be rate limited by the network admin simply setting the speed of their link slower in the configuration then what it can really handle.

Fix bug FM-206: Visual position changes between subclips. This isn't a subclip bug, but the nature of subclips make it more noticeable. The problem is we set the Video's dimensions to 320x240 by default, then set them again when the metadata is loaded. This results in a flicker for slow-to-load media (like a subclip). The fix is to set the dimensions to zero until the metadata has loaded.

When ever employee position changed, an alert should send an email

we have one requirement...
when ever any employee position changed, it should send an email ..how to do this one? any idea?
employee positions are recorded in PER_ALL_ASSIGNMENTS_F table, so if we create event alert on this table ( update ). event alert fires if there is any update to the table...but i want, only alert should send mail, when position column got updated in that table...
is it possible????

Oracle provides standard API’s to harness the databases SMTP server capabilities in sending emails. All email services are wrapped under package: UTL_SMTP. The protocol consists of a set of commands for an email client to dispatch emails to a SMTP server. The UTL_SMTP package provides interfaces to the SMTP commands. For many of the commands, the package provides both a procedural and a functional interface. The functional form returns the reply from the server for processing by the client. The procedural form checks the reply and will raise an exception if the reply indicates a transient (400-range reply code) or permanent error (500-range reply code). Otherwise, it discards the reply.
c := UTL_SMTP.OPEN_CONNECTION('<server>.unix.us.ups.com');
UTL_SMTP.HELO(c, '<server>.unix.us.ups.com');
UTL_SMTP.MAIL(c, l_recepient);
UTL_SMTP.RCPT(c, l_recepient);
UTL_SMTP.OPEN_DATA(c);

Tonaw,
If you import your still images using iPhoto, then the time you set for each still, using FCPX Perferences works.
You can set the durantion from 1 frame to as long as you want them view.
If you do not use iPhoto to import your stills, the default is 10 sec's.
FYI: This issue was brought up within a month after FCPX was released. They found out by using iPhoto, you had better control of the amount of time your still was viewed.
