Had anyone worked with 23.976 fps video?

It's the new hi def video frame rate that is supported in Logic 8, but I'm having some problems.
I also have a Canopus ADVC110 firewire to analog video out and the video is glitchy and crash prone.
I don't know if the Canopus really supports 23.976. Is there another video box that does support this frame rate?
Any info regarding this would really help me. Thanks
Marty

Some more info on La Wiki:
http://en.wikipedia.org/wiki/Frame_rate
http://en.wikipedia.org/wiki/24p
23.976p
Many 24p productions, especially those that are made only for TV and video distribution, actually have a frame rate of 24 * 29.97 / 30 frame/s, or 23.976frame/s (24/100.1% to be exact). Many use the term "24p" as a shorthand for this frame rate, since "23.976" does not roll off the tongue as easily. This is because the "30frame/s" framerate of NTSC is actually 30/100.1%, also referred to as 29.97frame/s – this framerate is matched when video at 23.976frame/s has a 3:2 pulldown applied. Similarly, 60i is shorthand for 60/100.1% fields per second.
Film productions may be shot at exactly 24.000 frame/s. This can be a source of confusion and technical difficulties if material is treated as normal video, since the slightly differing framerates can be problematic for video and audio sync. However, this is not a problem if the video material is merely treated as a carrier for material which is known by the editing system to be "true" 24frame/s, and audio is recorded separately from moving images, as is normal film practice.
Fun stuff!

Anyone worked with encrypted HLS streams in OSMF?

Hi,
I'm trying to find anyone that might have had experience working with an enrypted HLS stream in OSMF.
I've been using the library at http://code.google.com/p/apple-http-osmf/ and managed to get this working with a non-encrypted stream.
Also if anyone has any in depth knowledge of the HTTPNetStream and HTTPStreamSource classes it would be helpful to get in touch with you also.
Many thanks.
Mat

Hi,
I hate to disappoint you but I spent maybe 4 weeks trying to solve this problem without coming up with an ideal solution. In the end we concluded that this isn't really a viable solution for the product we were trying to develop. If you like I can tell you some of the things that I discovered but I really wouldn't recommend it based on our experiences.

Thwarted attempt to work with many hours of video

I'd like to draw clips from about 25 twenty-minute videos to create a single movie that's about 30 minutes long. Premiere Elements crashes when I try to put all of these videos into a single project. To deal with this, I had the idea of combining and drastically cutting about five videos, then saving them as a single .avi file, and then opening a new project that uses that .avi file and five additional videos from the original set. I would again make drastic cuts and save a second .avi file with all of the material combined. I thought by repeating this process several times--adding three to five files each time--I would eventually incorporate everything and avoid the crashing.
I took the first five videos, cut tons of stuff out of them, and then saved them as an .avi file. I started a new project and imported this .avi file and a new set of original videos. Premiere did not crash, so I thought this was going to work pretty well. However, when I went to save the second project as an .avi file, I was told that I was out of hard drive space--even on my external hard drive. I started investigating and, to my surprise, I found that my first .avi file was four times larger than the combined size of the original video clips! It was eating up tons of space and apparently the new .avi file wanted even more.
So, my brilliant idea is not going to work. Are .avi files always this big even though they are much shorter than the original .vob files? Why? Can I save the final projects in some other format that is more efficient with space and can be imported into later projects? Is there another, better solution to my original problem--too many long video clips for a single project?
Also while investigating the hard-drive space problem, I came across tons of rendered files. Many of them appear to be linked to the same project. Reading online, I learned that I should delete those through PRE and not through Windows. It also appears like it's an all or nothing proposition. I can't just delete the old versions?
In general, how does one do hard drive space efficiently in PRE?
Thanks for any help.

It sounds like your book will be helpful about how to best use space, Steve. I've ordered it. In the meantime, here are the answers to your questions. What is the best way for me to work with lots of long video files at once? Should I even be trying to reduce the original videos into smaller pieces?
Steve asks:
What kind of camcorder is your original video coming from and how did you get it into your computer?
   They were old Hi-8 tapes. I burned them onto DVDs, which created .vob files.
What settings did you select when you started your Premiere Elements project(s)?
   I did not change the original settings. How should I set them?
When you started each project, did you save it in a separate sub-folder on your external drive, as I recommend in my book?
   No. I move projects to the external hard drive as I complete them (after saving as movies to DVDs). I do this because I work on
   a laptop and do not consistently have access to my external hard drive. From your question, I’m guessing this is not a good
   approach. (Your book has been ordered).
Is your original video from a DVD? VOB files from a DVD are generally about 1/5 the size of DV-AVIs. I would also not recommend using them as your source video files if you can avoid it.
   Yes. No good way of getting around this as the original format, given the age of the source material and my limited access to
   conversion equipment.
Is your external drive formatted NTFS or FAT32 (as they come from the factory)? FAT32 drives have a file size limation that can often choke video editing work.
   Just checked and it is FAT32. Bummer. I assume reformatting it now would erase everything on it?
Bill asks:
Can you tell us about your system's entire I/O, i.e. all of your HDD's, and how you have them allocated?
   I use an HP laptop running Windows XP. The processor is P8600 @2.40 GHz. I have 3 GB of RAM (weird, I know). My internal
   hard drive is 150 GB, NTFS formatted. I have one external hard drive. It is 600 GB, FAT32 formatted. I’m not certain of the
   connection format, but I would guess it is USB2 since it is plugged into a USB port with the cord it came with.
Thanks again!

Anyone working with eView under JCAPS 5.1.X

Has anyone worked with eView under JCAPS 5.1.X? I am exploring the use of this tool in a project and I would like to talk to someone who has real world experience.

Using eView to uniquely identify the person is a good solution especially when customizing the OTDs to each specific source.
Deployment?
Well, it depends, impossible to make a blanket statement here.
With our case, a dedicated eView (logical host) domain is deployed, another domain is deployed for HL7 messages. JMS queues and topics are the the integration layers between them. Currently, looking into JMS Grid for a logical decoupling and clustering between domains.
Also, going to migrate our eGate SRE messages to JCAPS gradually, the messages which pertain to patient demographic events (ADT) will subscribe to JMS topics wired to eView.
The great thing about JCAPS (J2EE) is to logically partition components wand then deploy as required. For example, going to deploy HL7 message collaborations and eView components to a single domain now because transactions are low.
Designed this without consultants, have many years experience with J2EE software development, my problem is with the limited JCAPS Netbeans IDE functionality - ready for JCAPS 5.2!
Anyway, the eIndex project included with JCAPS, should get you started, forget the "patient" semantics, this is really a person in disguise.

Is anyone working with large datasets ( 200M) in LabVIEW?

I am working with external Bioinformatics databasesa and find the datasets to be quite large (2 files easily come out at 50M or more). Is anyone working with large datasets like these? What is your experience with performance?

Colby, it all depends on how much memory you have in your system. You could be okay doing all that with 1GB of memory, but you still have to take care to not make copies of your data in your program. That said, I would not be surprised if your code could be written so that it would work on a machine with much less ram by using efficient algorithms. I am not a statistician, but I know that the averages & standard deviations can be calculated using a few bytes (even on arbitrary length data sets). Can't the ANOVA be performed using the standard deviations and means (and other information like the degrees of freedom, etc.)? Potentially, you could calculate all the various bits that are necessary and do the F-test with that information, and not need to ever have the entire data set in memory at one time. The tricky part for your application may be getting the desired data at the necessary times from all those different sources. I am usually working with files on disk where I grab x samples at a time, perform the statistics, dump the samples and get the next set, repeat as necessary. I can calculate the average of an arbitrary length data set easily by only loading one sample at a time from disk (it's still more efficient to work in small batches because the disk I/O overhead builds up).
Let me use the calculation of the mean as an example (hopefully the notation makes sense): see the jpg. What this means in plain english is that the mean can be calculated solely as a function of the current data point, the previous mean, and the sample number. For instance, given the data set [1 2 3 4 5], sum it, and divide by 5, you get 3. Or take it a point at a time: the average of [1]=1, [2+1*1]/2=1.5, [3+1.5*2]/3=2, [4+2*3]/4=2.5, [5+2.5*4]/5=3. This second method required far more multiplications and divisions, but it only ever required remembering the previous mean and the sample number, in addition to the new data point. Using this technique, I can find the average of gigs of data without ever needing more than three doubles and an int32 in memory. A similar derivation can be done for the variance, but it's easier to look it up (I can provide it if you have trouble finding it). Also, I think this funtionality is built into the LabVIEW pt by pt statistics functions.
I think you can probably get the data you need from those db's through some carefully crafted queries, but it's hard to say more without knowing a lot more about your application.
Hope this helps!
Chris

What apps will work with the Apple Component Video cables ?????

I plan to order the Apple Component Video cables so I can watch the Netflix apps movies on my TV.
I know this app works with the cables but what else does?
The few apps I know of are:
Netflix
YouTube
included video app
but what else ?

Thanks. I did order it and it arrived yesterday. I have not done a lot but watched a couple things
with the Netflix app and I am very pleased.
The cable is only about 6 feet so I had to extend it but other than that I am pleased. Luckily, I already
had a 10' cable in the basement with connectors so now I can have my iPad where it usually is and
control things more easily.
A few more apps that work with it would be nice though. :>

Anyone working with Ascential and has loading issues

Hi,
Is anyone out there working with Ascential? We are loading data using Ascential to BW ODS. We would get a log that saids "sending 0 rows in package..." from Ascential, but when it gets loaded to BW, it said there is 1 record and the record row has blank field values when I reviewed the PSA.
Why is Ascential doing this? Is there any settings that I would have to set on the BW side? Would I have to add any code to the Update Rule routine to set the RETURNCODE? Please advise.
Thanks,
RT

Hi Rob,
I had faced some problems loading data using Ascential Data stage. Below mentioned are some of them:
Make sure that all the parameters in the transfer structure are mapped correctly in Ascential, according to the specified business rule.
(ii) Make sure that the number of fields in the transfer structure in BW are same as the mapped fields in Ascential.
(iii) Make sure that the size of the all the fields in BW are same as the mapped fields in Ascential.
My assumption for your problem could have been with the mapping of the fields.
Hope the answer was helpful!
Please let us know if you were able to resolve the problem.
Regards,
S.P

How do I get ym video to work with Lion? The video button is greyed out.

I thought this was supposed to be an automatic thing but I can't seem to get the video portion of ym to work with ichat. Any suggestions are appreciated. I am using Lion.

I kind of have the opposite problem. I need to know how to turn off my remote on the computer. I am using the remote for my Apple TV and it keeps making the volume on my Computer go up and down (with annoying sounds).
There used to be a way to un-sync the remote with the comp but I cannot remember how and the Apple help is not much help! I have Lion.
Thanks!
Best,

I would like to work with a selection of videos from my aperture library

I recently switched from iPhoto to Aperture. I did this in order to subdivide my iPhoto library, because it is now approaching 200 GB. I have not yet divided it, but I like to make little video vignettes from certain events. I used to be able to import just an event into iMovie, but now it seems to import my entire video library. It takes 20 minutes just to load iMovie. I don't want to see EVERY video in my library, I would like to see just the ones I have selected to work with. How can I do this?

Has anyone Worked with the Essbase Data Mining Module?

I'd appreicate if you could post a message if you have worked with the Predictor and Target Range Expressions, and data mining models in general? I am looking for some insights into what Essbase Data Mining can do...<BR><BR>Thanks.<BR><BR>- Sherwin

Yeah, unfortunately I am coming to the same conclusion.
This is the entire response I received for "instructions"
There are two projects: "fire_text_project" and "fire_text_project_plugin". The first once does not require any plugin because one particle effect is pre-rendred. If you have trapcode particular then you can use the second project and modify it.
Finally you can create a realistic fire text in after effects!
It took me a week to do the 3d fire simulation and render out all the 26 letters on fire. This is a very realistic fire thats simulated using advanced 3d software. The video is 621 x 720 px and it is 7 seconds long. All the letters has the color video and the black and white (alpha) video. You can use the alpha matte to create a tranpsarent background for the colored video. That's is how it is done in the two example comps included in the project. You will have to understand that the letters are video so it is not as easy as typing the letters using text tool to edit the text. Open the "1st text Example comp 1" comp and it has marker that explains in detail on how to edit it.
The two included comps are "Example_comp 1" and "Example_comp 2". These are great examples of what you can do with fire text but the possiblity is endless.You can create many interesting comps with these text on fire. Just to let you know the text that is rendered in 3d app is Arial Black.
Think I am going to have no choice but to simply cancel the sale and look for something else.
Thanks for all the input.

Can iMovie works with Canon HF20 digital video camcorder?

Hi there,
I was wondering if anyone out there have this digital video camcorder (Canon HF20) because I'm looking into buying one. I would like to know if this camcorder is user friendly with Macbook (2.2 ghz). Thanks.

I am not an expert but I believe it does. I have the same camcorder and MacBook Pro. The laptop recognizes the camera and it is a straight forward import from camera to iMovie.

Anyone working with XML in portlets? How?

Do you work with XML/XSL in a JSP Portlet to build your presentation?
We are having trouble with german Umlauts and want to know a way for XML in portlets in general.
Thomas

Hallo Ingo !
We use the Oracle XML Parser and XSL transformer in a JSP Portlet. The XML is referenced throu a URL from our XML server.
The XSL file is in the portlet directory.
Our Problem is:
Even if we use encoding attributes set to UTF-8 we are not able to display Umlauts correctly. They are not encoded to HTML Umlauts (e.g. ü to ü).
We tested our code with Apache Xalan and Xerces and everything works fine.
I think that Oracle XML parser treats things not as they are recommended by W3C.
Finally we gave up parsing XML with oracle Parser and now use Apache XML/XSL Parsers.
Or do you know a better way?
Thomas

Working with WMV Google Earth Video

Howdy. I am attempting to integrate a Google Earth movie I recorded (WMV format) into my project and to put it lightly... it's not going well. Not only is it unable to render the timeline in the project window when it gets to the wmv footage (just gets stuck while audio continues), but it takes an insanely long time to render... six hours for a 30 second clip.
I took a shot at transcoding the clip using handbrake to mp4 but it crashed instantly when added to the premier timeline.
Sorry for the ametuerish question. As you can tell, I'm new at this. Any help is much appreciated.

Good news. AME is a good "converter" too, and is often overlooked. While it might not have the range of some dedicated conversion apps., when it can work with footage, it does a good job.
Thanks for reporting your success!
Good luck,
Hunt

Anyone worked with activex controls within labview

I am working on an new project and the instrument has an activex/Dcom control. Any ideas on how to work with this in my laview (8) environment?

Sounds like you are having a control which can be embedded.
You can create an empty ActiveX container on the front panel (Container palette). Rightclick it and select "Insert ActiveX Object" and browse for your control. If you did not register it, you will have to switch to "Create Object From File" and browse for the ocx/dll-file.
The rest is standard ActiveX interfacing using property/invoke nodes.
hope this helps,
