Experimenting with FCP/ Real time rendering question

Hello, I am preparing to purchase a Mac Pro and spent some time at the local mac affiliate store playing with FCP and motion.
In fcp I took two clips and dropped them in the timeline, adding the 3d cube transition, and some filters to both clips.
I was looking at performance of real time rendering on teh base config of the MP I plan on purchasing.
I then added another clip above these two, intending on dropping the opacity to further push the RTR (real time rendering). This clip overlapped the transition of the two other clips in v1 and v2.
When attempting to play the timeline the viewer window now said "Not Rendered"
My question is:
Is there a limit to how many tracks can be run under the RTR? Why did I get this message?
My main reason of the move to a Mac Pro is to get away from constantly pre-rendering.
Thanks everyone in advance!

Sounds like you know what you're doing and what you expect. A factor that has not been mentioned yet, besides RAM, prefs and drive speeds, is your video format.
Also, the new rev of FCP is taking advantage of tons of processing overhead, vastly increasing the amount of stuff you can do in real time. However, real time is largely a preview operation, regardless of the machine or system, unless you are using proprietary codecs, such as Media 100, that might be hardware-assisted. Output is almost always a rendering issue, multiple stacked or processed layers require the creation of new media.
The only way you're going to be able to decide if Macintosh and FCP are right for you is to demo thoroughly and that requires using your own footage.

Synchronise time in array with the real time from computer

i need help in syrnchonising my array and the real time running in my computer
As stated in the text file attached,
12:32:30 AM 0.38 1.14
2nd column is wind speed, 3rd is gust speed.
i would like to display the wind speed in a gauge with the right values. like for example, at 12:32:30 AM OF REAL TIME, NOT BASED ON THE TEXT, i would like to display the 0.38m's of wind speed in the gauge.
how do i sync the time in array with the real-time?

Don't continually post the same question over and over. If you have new information, add it to the original thread. Did you actually click the link under the word "duplicate"?
Chopping up a discussion about the same thing into several threads (like here is this thread, but also here and here) serves no useful purpose. It will not increase the chance of a good answer, in fact most people will simply ignore it.
Imagine if everybody else would post like you! Every discussion would be if three different places and we would have three times more threads.

Real time interview questions

Hi gurus
Can anyone of u pls give answers for the following real time interview questions.
1.How do you implement a new object required by ur Client...and what are all the proccess up to Production Server....?
2.What is the Role played by RFC is SAP Systems
3.. What are all the initial things done to you while u are put in to the team....?
Pls do the needfull
Thanking you
sure i will assign full points

1._How do you implement a new object required by ur Client...and what are all the proccess up to Production Server....?_
- Develop the New Info object
- Test them Info object in Quality(if you got one in your Landscape)
   - To test in Quality,Firstly you need to "TRANSPORT"the obj to Quality(TRANSPORT CONNECTION - OBJ - TRANSPORT(assign to a Transport Request)(truck icon)
   - Once the obj is Tested fine without any bugs.errors,
- Transport the obj from DEV to PROD
- Transport Conn - Obj -Transport(truck icon)
   - SE09 (Release the particular Request)
   - STMS (Import the Request to PROD) (Can be done by BASIS)
2)_What is the Role played by RFC is SAP Systems_
    - RFC(Remote Function Call) used to help establish connection between the BW and the Source system.
    - You setup the RFC in SM59
3)_What are all the initial things done to you while u are put in to the team....?_
    - This literally depends on the Type of Project you are deployed.(Implementation/Support)
Hope this stuff help you out..
cheers

How come you can not use more than 126GB of a 1.5TB diskdrive with LabVIEW Real Time?

How come you can not use more than 126GB of a 1.5TB diskdrive with LabVIEW Real Time?
This is only 8.3% of the available disk drive space!
http://digital.ni.com/public.nsf/allkb/E7E2F5657B6026358625750B007201A6?OpenDocument
National Instrument's solution is either reformat you drive to less than 126GB or replace the drive with one less than that size.
Please NI, tell me you are going to fix your LabVIEW Real Time soon, and that we won't have to wait for LabVIEW RT 9.2.1 in 2011 for this one to be fixed.
http://upload.wikimedia.org/wikipedia/commons/9/90/Hard_drive_capacity_over_time.svg
Drives as large as 126GB or more have been around since about mid 2002. That's about 7 Years now and LabVIEW Real Time STILL can't use drives larger that 126GB! Please NI. Do something.
We deserve fixes to the old versions of LabVIEW RT. How about updates to LabVIEW RT. Such as 7.0.2, 7.1.2, 7.6.2, 8.0.2, 8.2.2, 8.6.2.
We don't need new features or versions of LabVIEW RT such as 9.0 until we have some of bugs fixed in the existing versions.

Coq Rouge (formerly t06afre),
The RealTime OS is an NI Product that is purchased from NI.
NI may or may not outsource design, developement, or manufacturing of the products that it sells under its own Company name.
For this reason I would be concerned if I were a PXI Embedded Controller designer/developer in the United States.
Yes, 126GB is some space. I see that there are now 2TB drives available. 126GB would be 6.3% of a new 2TB drive. Should we all be happy with being able to use 6.3% of the available drive space. Moore's Law seams to be alive and well. Drives larger than 126GB have been readily available for 5 or 6 Years. This should not be a surprise to NI. Why don't they do something about it.
Thanks for the trivia on Bill Gates. I must have missed that one since I don't try to keep up with Microsoft. I believe that he is a wonderful person and he and his family are doing wonders for the world in their "retirement". The world needs more like him.
What I do remember is Steve Jobs telling us that we would never need more that 128MB and that we would never to need to do anymore software development because everything was already in the "ToolBox".

MultiProvider with two real-time InfoCubes?

Hi,
I created a multiprovider with two real-time Infocubes. I need to create a formula in FOX editor where I have to update only one InfoCube. Is it possible? If so, I am looking for syntax with InfoCube name in the formula. The KeyFigures have the same names in both InfoCubes.
Any help would be appreciated.
Thank you,

Hi Pratyush,
I am using IP. I created Aggregation Level, Filter, etc. It created a characteristic "0INFOPROV" and I used that cha. to read data and to write the data. It did not work.
Here is the problem.
- We have one basic cube (history data: HCUBE) and two transactional cubes (actual data: ACUBE and plan data: PCUBE)
- Created a multiprovider (MULTI) for HCUBE, ACUBE, PCUBE
- Also created Agg level and filter
- Note: Three cubes have the same Key Figure (0Amount)
- Created a planning function and tried something like {KF, PCUBE} = {KF, MULTI} (as suggested by Andrey)
- Task is to read data from HCUBE and ACUBE and only write to PCUBE.
- I am able to read data but unable to write data.
Any ideas?
Thank you,
Vidya

Help needed with CVI real time

Hi,
I am new to CVI real time and need help related to this. I will explain my scenario:
1. I have few configuration files (INI). Need to validate the files (range checking..etc) during start of the application.
2. When user clicks "START" in the user interface on the host machine, I need to generate outputs (analogs/discretes...) based on the settings in the config file and read some inputs from other instruments. ( I/O tasks like generating outputs/reading inputs i am planning to perform in RT side)
3. From the user interface, user can also change the config files. if user changes the files, again file validation needs to be performed. After changing the files, if user clicks START, need to take the newly enetered config files to perfom I/O tasks.
4. I am NOT using reflective memory for my application.
I am confused in the following area:
1. File validation during startup , do i have to perform on both host and RT side?????
2. if configuration files are changed in the host side by the user, how i have to send this latest file names to RT??? I think i should not send file names, i need to read from the file and its contents i need to pass to RT....Pls correct me , I am not sure about this....
3. If I have to send file contents to the RT, how I have to do that....means i have to use structures,..???
Please guide me. Any help would be highly appreciated.

haari
Solved!
Go to Solution.

Hey haari,
1. File validation during startup , do I have to perform on both host and RT side?????
This depends on the full range of responsibility for the INI files. If they are all needed simply to change what the I/O tasks are for, then you would technically only need to validate the INI file contents on the RT side. You could, however, validate on both sides if you wanted to. However, I would probably set it up such that I send a validation command to the target, have the target run a component of the code that validates the INI contents based on how I instructed it, and then return a message that says whether or not it met the requirements I specified. However, if you are concerned with offloading that process to the user desktop (instead weighing down the RT controller performance), you could FTP the file off of the controller and perform the validation process on the host side.
2. if configuration files are changed in the host side by the user, how i have to send this latest file names to RT??? I think i should not send file names, i need to read from the file and its contents i need to pass to RT....Pls correct me , I am not sure about this....
You can send them to the target over FTP. This can be done programmatically, through MAX, command window, or a Web browser.
3. If I have to send file contents to the RT, how I have to do that....means i have to use structures,..???
This is basically addressed in answer to question two. You would not need another structure in your RT code to handle the FTP receive component as this is handled by the FTP Client/Server communication. However, in the event that you successfully FTP a file to the target, you should likely send a message from the host to the target so that the target can respond accordingly and reload the file, reestablish the I/O values, run an idle procedure, or do whatever you like.
Hope this helps. Have a great day!

Jmx with java real time

Hi David,
my question for now is very general.
can we use jmx with jrts???
Gabi

Hi Gabi,
Some additional information:
- JavaRTS does support the JMX protocol
- JavaRTS supports most of the monitoring & management functionalities provided
by HotSpot MBeans
- some functionalities are disabled by default because they would create jitter (like
getting the stack trace of java threads). Default can be changed through the
realtime.debug MBean)
- JavaRTS comes with a few additional realtime specific monitoring beans.
Note that JMX relies on threads to do its work. These threads are not real-time.
Hence, if the realtime threads (including the RTGC) are consumming all the CPU,
you may not be able to call MBeans to see what is happening and take corrective actions.

SOA real-time design question

Hi All,
We are currently working with SOA Suite 11.1.1.4. I have a SOA application requirement to receive real-time feed for six data tables from an external third party. The implementation consists of five one-way operations in the WSDL to populate the six database tables.
I have a design question. The organization plans to use this data across various departments which requires to replicate or supply the data to other internal databases.
In my understanding there are two options
1) Within the SOA application fork the data hitting the web-service to different databases.
My concern with this approach is what if organizations keep coming with such requests and I keep forking and supplying multiple internal databases with the same data. This feed has to be real-time, too much forking with impact the performance and create unwanted dependencies for this critical link for data supply.2) I could tell other internal projects to get the data from the populated main database.
My concern here is that firstly the data is pushed into this database flat without any constraints and it is difficult to query to get specific data. This design has been purposely put in place to facilitate real-time performance.Also asking every internal projects to get data from main database will affect its performance.
Please suggest which approach should I take (advantage/disadvantage. Apart from the above two solutions, is there any other recommended solution to mitigate the risks. This link between our organization and external party is somewhat like a lifeline for BAU, so certainly don't want to create more dependencies and overhead.
Thanks

I had tried implementing the JMS publisher/subscriber pattern before, unfortunately I experienced performance was not so good compared to the directly writing to the db adapter. I feel the organization SOA infrastructure is not setup correctly to cope with the number of messages coming through from external third party. Our current setup consists of three WebLogic Servers (Admin, SOA, BAM) all running on only 8GB physical RAM on one machine. Is there Oracle guideline for setting up infrastructure for a SOA application receiving roughly 600000 messages a day. I am using SOA 11.1.1.4. JMS publisher/subscriber pattern just does not cope and I see significant performance lag after few hours of running. The JMS server used was WebLogic JMS
Thanks

Real Time kernel questions

I decided to compile myself a new kernel using a PKGBUILD from AUR, which contains Ingo Molnar's real time patch. I know that there are some entries int the wiki about this (Kernel Compilation with ABS, Custom Kernel Compilation with ABS, Kernel Patches and Patchsets), but they don't answer all of my doubts.
The major question is related to my graphic card's drivers. I'm a happy Radeon user using fglrx proprietary drivers. At the moment they are working fine on a vanilla kernel form [core], the problem is whether I would have to do some voodoo to make them work on a rt-kernel? Now I know what is written in wiki about installing Catalyst drivers on a custom kernel, but when on Mandriva I tried to install 8.1 on my rt-kernel, I had to do some tricks and recompile fglrx to make it work. Does anyone tried installing Catalyst drivers ver. 8.2 on a real-time kernel from AUR?
Another thing: I have a .config file from the previous rt-kernel. Would it be suitable for 2.6.24?
Finally, I recently read about grsecurity patchset. Did anyone tried it on Arch, especially on a real time kernel? Any problems?
Waiting for suggestions

broch wrote:first I hope that you understand that RT kernels on desktops are slower than preempt default or vanilla kernel?
I'm using one on my Mandriva 2008.0 and didn't notice any slowdown.
broch wrote:second: I use grsec (or RSBAC) kernels.
grsec will not work with anything messing up with memory (even Kolivas patches in past had issues with grsec). This can be fixed but then what is the point of enabling hardened kernel with disabled features?
I simply patch vanilla with grsec.
Remember that some pax options are incompatible with X (all explained when option is selected, so no way to make mistake)
finally it works well lowest overhead, best speed and easies to manage among kernel hardening patches (I do not count Apparmor, as this is rather limited tool)
If I understood you, then it's a choice between real time and more security, right?

FCP Real Time Playback

I want to do real time playback of a FCP project from my MacBook Pro, and it appears my new Matrox MX02 Mini box will allow an HDMI output of my 720p60 project from the MacBook Pro. Pretty cool. What are your best suggestions for encoding a reliable playback product? Compress to an MPG2 program stream? Make an HD Quicktime? Or....? Bye bye 480 DVD's!

David, if I could ask your setup for a QT playback out of the DVI port on the MacBook Pro:
1) You take the DVI output into a DVI monitor, or do you use a DVI-to-HDMI cable?
2) Audio is from the quarter-inch jack on the MacBook Pro?
3) Can you achieve good 720p?

Can you use event case with labview real time?

I have a real time application I am putting together and until recentally have concentrated on getting the data acquisition working as expected.
I am using a PXI-8183 in a 1031 chassis.
I am now trying to add the functionality for setting up the system in the form of a GUI remote front panel that I connect to with a host laptop. I am connecting with the host as expected and it seems to be working well in that respect.
My problem is with event cases, operating in a while loop on the target. They just dont seem to want to trigger when i click on a button I have set an event for.
I have looked through the documentation and cant see any reference to issues with event cases on rt, but I feel I am missing something fundamental. Can anyone help?

Barry

Bhalout

Hi Bhalout
We can say every project is a challenging one .... But one of the case i can explain is .........
We are getting monthly data from source , but we need maintain that data in ODS according to Weeks.
Example:
CompanyCode| Month | Key Figure
1000 | 200703| 100
I have split the monthly records in to Weekly record when loading the data in to BW. This is done by selecting Return Table option in the update rules of a Key figure and a writing a start routine..........
Example:
ODS/Cube Data
CompanyCode | CalMonth | Week | KeyFigure
1000 | 200703 | 200709 |25
1000 | 200703 | 200710 |25
1000 | 200703 | 200711 |25
1000 | 200703 | 200712 |25
Hope this example works..........
Some other challanges you can explain about are
Query Performance issues when go live and you can explain about maintaining aggregates, data load issues such as failing of delta in a process chain .........and how you resolved those issues.
One example is you can say Users want to see some special characters in the report and I used RSKC transaction to allow those special characters.........
Mostly this question is a general question and I hope you can get more real time scenarios from sdn.......
Assign Points If useful.......
