Best quality for compressing data vide file

Hi,I have a 5minute clip which I have been asked to burn on a normal cd as a data file.Whats the best exporting option I can use.should I use compressor? or should I go directly to the quicktime conversion option in final cut?
thanks

I hope I don't have this worng, but export>quicktime movie will only make a movie based on the currently selected sequence settings. Sure you can make some choices from the drop down menu, but the default is the current sequence setting.
So if this chap were working on a 320x240 video sequence with a horribly lossy compressor, then he'd end up with a pretty rough finished quicktime.
Choosing quicktime conversion does not necessarily compress the footage if you don't select a compression method that will destroy it. You can just as easily not compress it via this method. I would say that using Quicktime Conversion means you really have to know what you are doing so you get all the settings right to match your destination format.

Best Method for Saving Data to File?

Hi,
We're using labVIEW 2009 to acquire data from our instrument. In the past we have used the "write to labview measurement file" express configuration tool to save data to a file. However we had some issues with our VI - occasionally we would lose data or column headers somewhat erratically and were never able to sort out the problem. We would like to rewrite our VI with the best possible solution.
Here's a summary of what we would like to do:
Save 30 variables at a rate of roughly 1 Hz. We would like one set of column headers per file so that the data can be easily imported into labVIEW with the variable names intact. We will be collecting data continuously, so we would like to divide the data into 3-4 files per day. Ideally, the program to start new files at the same times from day to day and the filename could be configured to include the date and time/file number.
I am hoping that users can provide a little feedback about methods that were most successful and reliable. From what I have read there are a few different ways to do this (express VI, tdms, "write to text file"). Any thoughts or relevant examples would be quite useful for us!
Thanks for your help!

Is it correct to say that in your method, the indexing results in building up the data into one large array of data before saving it to the file with the column headers and filenames appended? If we are writing data at 1Hz for 6 hours of time, will we run into an issue being able to store all the data?
Yes the indexing will build up one large array. If this is a problem due to array size and memory, you will have to write more often. You can write every second, that should not be a problem. You should still write the column names to the file first, and have the append input set to False (or nothing wired in since the default is false). This will create a new file with the headers only. Then the data write has a True wired in so that the append takes place. If running for 6 hours and gathering data once per second, your array will contain 36,006 rows of data. I'm not sure if that would cause a memory problem or not.
Meg T wrote:
it also seems difficult to incorporate headers into express VI if you are writing the data continuously as a part of a loop with the "append" option.
If you write the headers before the loop as I have shown, and use append inside the loop, you will not have problems.

Best settings for highest quality for exporting a .mov file to h.264

Hi,
I want to know what the best settings are for the highest quality for exporting a .mov file (720p50) to h.264. I want the same quality as the original.
I want to know the data rate etc.
regards,
Jeroen

There is no way to get the exact same quality when transcoding from an editing source to a highly compressed H.264 QT. However, you can get a real high quality by adjusting the data rate.
However, these things depend on the length of the original. I routinely encode H.264s with good results in the 3000-5000 data rate range. I also make sure that I use multiple pass encoding. Take a short snippet of your project (10 seconds or so), and try various bit rates until you have one you like that doesn't take forever.

Best quality for youtube

I made a video and its 2.01 GB in iMovie. i want to put it on youtube but I want the best possible quality. The limit for youtube is 100MB whats the best way to compress my movie?

Hi F,
I followed your link and found your instructions about exporting from iMovie with best quality for YouTube.
The instructions were pretty clear, although my options didn't line up with them exactly (I'll tell you my explicit settings below). Still, I exported it successfully.
Then I uploaded the resultant .mov file to YouTube. When it was all finished processing, I viewed it. After the first fraction of a second all I saw was garbage -- just junk patterns filling the screen. The sound was excellent. (by the way, I had lots of very short clips in there -- 00:00:03 in length (not sure what the units are).
So I went back to iMovie, opened up my movie project. Played the video. Now it is intermittent garbage, too. Looks just like the uploaded file, but only intermittently.
Here are the exact options and settings I used for export:
File->Share, chose quicktime and expert settings, pressed the "share" button.
in the Export dialog, I selected "movie to quicktime movie" and clicked on the "options" button.
Options:
Video:
Settings...
Set compression to mpeg-4
Set quality to medium
Set frame rate to 30
Let Key frame and Data rate defaulted (unchecked)
Filter...
didn't look at this. Now that I do, it's set to "none"
Size...
Selected the "custom size" radio button and set it to 320 x 240
Sound:
Settings...
format: uncompressed
sample rate: 44.1khz
sample size: 16
channels: 1 (mono)
There was also a check box for "Prepare for internet Streaming"
It was already checked and set to "fast start"
I didn't change it.
If you could give me any further help, I'd really appreciate it. This was my first attempt to put anything on YouTube.
Thanks a lot,
Bruce Delaplain

Best setup for a non-Mac file server?

I have a dual xeon server, with a SATA RAID5 I want to use as a file server in a cross-platform environment.
*What I've tried and the issues...*
At first I considered using Windows 2003 (Win2k3) but Services for Macintosh (SFM) is an older version of AFP and thus only supports 31 character filenames. With all our Macs supporting SMB/Samba/CIFS and Apple touting that "Macs and PCs can co-exist harmoniously on the same network" I figured I would give that a try.
SMB doesn't work.
Sure I can create a connection, but transferring files is a completely different story. I'm trying to backup application and system data, but companies such as Adobe and Apple have named some of their files with special characters that can't be transferred over SMB. I know NTFS doesn't support these characters, but I though a Linux box using SMB would work fine. It doesn't. It's the protocol which keeps me from transferring the data. I end up with the lovely error message of "You cannot copy some of these items to the destination because their names are too long or contain invalid characters for the destination..." (what's sad is, if you google for " because their names are too long or contain invalid characters for the destination" you only get 6 results.)
So I thought I would give NFS a try. Apple says "Viewed from Mac OS X, [connecting via NFS] is just like connecting to an Apple or Windows server." No. It's not. NFS shares don't even show up in the Finder's Network listing. There are also a pile of other hurdles which are only tackled by savvy, command-line using users.
So that leaves me with AFP. Win2k3 doesn't support filenames longer than 31 characters, and Win2k8 is dropping SFM altogether. Off to choose a *nix flavor, but that requires Netatalk. It hasn't been updated in years, it has many bad performance reviews... and most distros have removed it. I can download and install it. Oh, but that requires I get the kernel source files. Then I have to create an RPM an that's not working... now I'm several levels deep in trying to figure out how to get Netatalk working and I'm not even sure it will work.
*What's the best setup for a non-Mac file server?*
FreeNAS seems promising, but it's in alpha/beta and they have all sorts of warnings regarding potential data loss. Sure there's ExtremeZ-IP, but I really don't want to spend $675 do something Apple claims OS X can already do. I can put just about any non-Mac OS on this thing... what's the best way to set it up so it works?
Thanks much.

Rick may be right because although i didnt think of it before i tend to have notoriuosly long classnames for my php classes and i have used samba on occasion (when rsync is out of the question for one reason or another) and never had a problem. I use kubuntu (feisty at the moment )with an ext3 filesystem. if i have a chance this evening ill give it a try and see what happens.
You could also possibly use FUSE to use an ssh filesystem for the shares... i don tknow how that would figure in your back up though.
Also if worse comes to worse you could tar or dmg the the necessary files... just some thoughts.
Ill be interested to know what you end up implementing....
OH one last thought... Compile Darwin from source and use that as your server

Best practice for heirachical data

First off, I have to say that JMX in Java 6 is terrific stuff. Bundling jconsole in with Java has made JMX adoption so much easier for us.
Now, to my question. We have read-only hierarchical data (think a DOM tree) that we would like to publish via JMX. What is the best practice? We see two possibilities:
1. Publish each node of the tree with it's own object name and type. This will allow jconsole to display the information in the tree control.
2. Publish just the root of the tree with an object name and type and then use CompositeType to describe the nodes of the tree. This means you look at the tree in the "Attribute Value" panel of jconsole.
Is there any best practices for such data? We have implemented #2 and it works but we are wondering if long term this might lead to unforeseen consequences.
Thanks in advance.
--Marty

Path,
I did go with #1 and it worked out great. Every node in our tree is an ObjectName node. Works very well for us.

Best practice for sharing data with model window

Hi team,
what would the best practice for sharing data with a modal
window be ? I use a modal window to display record details from a
record list, but i am not quite sure how to access the data from
the components in the main application in the modal window.
Any hints would be welcome
Best
Frank

Pass a reference to the parent into the modal popup. Then you
can reference anything in the parent scope.
I haven't done this i 2.0 yet so I can't give you code. I'll
post if I do.
Oh, also, you can reference the parent using parentDocument.
So in the popup you could do:
parentDocument.myPublicVariable = "whatever";

Can't open MOV files in FCP: "Searching for movie data in file..."

I know this has been posted before, but none of them seem to match up to what I'm all of a sudden dealing with. I have 4 MOV files that I'm converting to WMV. Movie 1 & 2 exported fine. Now, however, any time I try to open another MOV file, I get an error that it's "Searching for movie data in file..." and the file name is ALWAYS the same. The weird thing is, the file it's looking for is none of the 4 movies I'm working with. So how did the first two work and this pop out of nowhere??
I have cleared out the render cache. Dumped all the cache and prefs files I can find, etc. Restarted the machine. Started FCP with the Option key held down.
I've searched everywhere, but people usually seem to come across this error while opening FCP (I'm running 6.0.6). This only happens when I open a MOV file (oddly, I can open WMV files in FCP without issue).
HELP!

So, I open the movies in QT and the EXACT same thing is happening. So it appears the guy who created the videos did something when he was making them (probably made a reference files along the way). I'm having him re-export the MOV files.
So, it's not a FCP issue.....

Best choice for a date column in forms

Hello,
I want to know what is the best choice for a date field that the user have to enter manually. I read on a other post that a calender control is not directly implemented in forms 9i. So what is the best choice to be "user friendly" with a date field in a form?
thanks in advance.

Hi
Don't know if this would be much use to you, but I wrote this function 'Check_Date' a while back to check whether the user had typed something which could be interpreted as a date. You'd make your date field into a Text Item, and include a call to this function (which could be in your form, or in a library) in the WHEN-VALIDATE-ITEM trigger on the item, ie:
IF NOT check_date(:ITEMS.date_item1, NULL, NULL) THEN
    RAISE FORM_TRIGGER_FAILURE;
END IF;This would mean that the user could type 'T' or '*' for today, '+1' for tomorrow, '-7' for one week ago, or the date in a variety of formats. When they leave the field, the function tries to resolve what they've typed into a date, and sets the field to a date in the correct format.
('Display_Alert' is just a function to display a named alert with a message.) It can also be used to check that the date entered doesn't fall outside upper and lower bounds. Code follows:
FUNCTION Check_Date (text_in        IN OUT VARCHAR2,
                     lower_bound_in IN DATE,
                     upper_bound_in IN DATE)
RETURN BOOLEAN IS
first_letter      VARCHAR2(1) := SUBSTR(text_in, 1, 1);
date_ok           BOOLEAN;
this_date         DATE;
date_diff         NUMBER(8);
output_format     VARCHAR2(12) := Get_Application_Property(BUILTIN_DATE_FORMAT);
TYPE date_format_table_type IS TABLE OF VARCHAR2(12)

    date_format_table(5) := 'YYYY-MM-DD';
    date_format_table(6) := 'YYYY-MON-DD';
    --Use of T, or * for today's date...
    IF UPPER(text_in) IN ('T', '*') THEN

IMovie error 'searching for movie data in file "IMG_4365.MOV"'?

my iMovie goes into a loop at startup with the message "searching for movie data in file IMG_4365.MOV"?
I'm on iMovie 09 (version 8.0.6) and it's driving me mad. Help!

I am also seeing this bug and often work on 400mb+ presentations that use larger screen sizes and have lots of video assets for work. On large files I find that autosave is not ideal, and would also like a way to turn it off. The computer that was seeing the issue was running 10.7.5. It was just updated to 10.8.2 so I am keeping my fingers crossed that it works better now. Time will tell.
I also really hope that Apple gives us a real refresh on Keynote on the Mac. As old as it is, it still ahead of Powerpoint. But it wont stay that way forever standing still and nobody else has a better alternative that is as fast and flexible to work with. They are squandering somthing special by letting it gather dust.

Searching for movie data in file Name-FIN-00000001

While starting up FCP (6.0.6) gives an error message "Searching for movie data in file Name-FIN-00000001".
After 10 to 20 min FCP will start up.
How do I get rid of this annoying error message when starting up?
Thanks W.

As Jim says, this is a render file. However, simply rendering it won't fix this. What is causing this error is a QT reference movie in the project. When you export a QT movie, and make don't make it self contained, it is a reference movie that references media files and render files. When a render file is deleted (FCP does this automatically when the render file is no longer needed) then the refrerence movie can no longer function... one file it references is gone. Simply re-rendering won't fix it, because it is referencing that SPECIFIC render file.
You need to find and delete the QT Reference movie from your project.

Searching for movie data in file

Does anyone know how to fix the problem of the "Searching for movie data in file" interruption and annoyance? I can not access my movies to edit - or do anything for that matter - because this thing keeps popping up. Any help would be GREATLY appreciated!
Thanks!

Hi
Did You move or alter any folder named
• iMovie Event's - or -
• iMovie Project's
Don't - If done try movien all back excatly.
Moving Event's and Projects must
• be done within the iMovie Application
• to a Mac OS Extended (hfs) formatted external/secondary Hard Disk
(Never to - NetWork Storage or UNIX/DOS/FAT32/Mac OS Exchange formatted devices)
Free Space on Start-Up (Mac OS) Hard Disk. How Much ?

Searching for movie data in file "Untitled.mov"

Ok I have already searched in the forums and none of the solutions have worked. Can anyone help me with this problem?
When I open Final Cut Pro, before the full program opens this error pops up:
Searching for movie data in file "Untitled.mov".
Screenshot - (http://imgs.hnation.org/uploads/714c01ba72.png)
After like 10 seconds this error then pops up:
The movie file "Untitled.mov" cannot be found. Without this file, the movie cannot play properly.
Screenshot - (http://imgs.hnation.org/uploads/8c5564c42f.png)
I have tried pressing the "Search" button and have tried every Untitled.mov file I could find, but none of them worked. If I press "Cancel" then the same thing happens 5 more times until Final Cut Pro actually opens.
Help Please. Thanks!

what if I am unable to get a hold of the footage again to re-import? Is there an alternative way?
There is no alternative. The movie file is missing information. Either you captured footage and it broke it up into smaller segments (-av-0, -av-1, -av-2) and one or more of those files are missing, or you exported a Quicktime REFERENCE movie, and reimported that into FCP...and have since deleted some media that the reference file....references.
Either you have it or you don't. If you don't have it...and cannot reimport it, then you are SOL. The only way to get rid of the message will be to delete the clip in the project that is causing the error.
I have already tried reinstalling 3 times. The same error still pops-up.
This is not an error with the software. You have a clip in the project that is missing something.

'Searching for movie data in file' glut

I had to move QuickTime (QT) files to another hard drive. Now, when I run iDVD to work on the DVD project, I am constantly bombarded with "Searching for movie data in file..." prompts. Even when burning a Disk Image. Eventually, it finds them (I haven't deleted anything). All the files under "Project Info" are checked off. It eventually stops and the iDVD Project behaves normally. But when I make another change in iDVD, it starts again.
Most of the QT movies used in the DVD are QT Reference Files, with their own links (also on the same drive). So when it's "searching" it's looking for those individual sub-movies in the QT Reference file.
Is there a way to fix this? This didn't happen before I installed the new drive and moved the files.

Hi
Most probably it looks for the parts on the absent drive and has to search to
find them on the new on.
I don't think You can alter this in iDVD.
I think I would ease out by going back to original Mac and now either:
• Re-set scratch disk to the new one (all 4-5 places in FCE/P) - or
• Make new QT.mov files - but tjis time "Self-containing"
(THIS IS MY Guessing - and may be not working)
else (bonus)
*When not knowing what to do.*
• Free space on internal (start-up) hard disk if it is less than 10Gb should rather have 25Gb
• Hard disk is untidy: Repair Permissions, Repair Hard disk (Apple Disc Util tool)
• Delete iDVD pref file - *or rather start a new user/account* - log into this and re-try
• Program miss-match: iDVD 5.0.2, Mac OS X.4.11 AND QuickTime 7.4.1 - is OK - DON’T work under Leopard
• Program miss-match: iDVD 6.0.4, Mac OS X.4.11 AND QuickTime 7.4.1 - is OK (might work under Leopard)
• Program miss-match: iDVD’08 v. 7.0.1, Mac OS X.4.11 AND QuickTime 7.4.1 - is OK (might work under Leopard)
• iDVD (08) v7 Locate theme folder. Move out iDVD1, iDVD 2 and eventually iDVD4 folders to desktop - re-try
iDVD 6.0.4 and iDVD 7.0.1 are compatible with Mac OS X 10.5 Leopard
iDVD pref file resides: Mac Hard Disk (start-up HD)/Users/"Your account"/Library/Preferences
and is named: com.apple.iDVD.plist
While iDVD is NOT RUNNING - move this file out to desk-top.
Now restart iDVD.
Yours Bengt W

Searching for movie data in file "******.mov"

The last couple of weeks I've been getting dailog boxes that freeze up Keynote with the following message:
Searching for movie data in file "******.mov"
It runs through all the different MOV or MP4 video files I have in that particular Keynote and doesn't allow me to do anything but wait. I've tried moving the file to another HD but this didnt't change anything. Also changing the save settings didn't help.
It happens a couple of times an hour and is getting annoying. Anyone have any clue how to solve this?

I am also seeing this bug and often work on 400mb+ presentations that use larger screen sizes and have lots of video assets for work. On large files I find that autosave is not ideal, and would also like a way to turn it off. The computer that was seeing the issue was running 10.7.5.
