Is it better to encode a FLV before uploading to Youtube?

Does Youtube apply additional compression to a FLV even after
it was
obviously encoded in Flash as a FLV? If so, what is the best
format to
start with when uploading to Youtube, or what is the best way
to prepare
a FLV before uploading?
Thanks!

You can actually have both versions installed at the same time. Each version of LabVIEW will be installed in its own directory under the National Instruments directory. This way you can support projects that have not upgraded to the new version.
LabVIEW 8.2 is not technically an "Upgrade" to an older version. It's just a new version.

Sharpen video footage before uploading onto YouTube

Basically I'm wondering whether there is any way to sharpen up the video footage in iMovie '08 before uploading onto YouTube to compensate for the 'softening' of the video by the YouTube rendering.
I've compared the video's I've uploaded to the same ones uploaded by a few other users and it seems to me that my versions seem to be a little bit blurred. I've tried most of the tricks like resizing the video to 640 x 480 so YouTube compression doesn't have to do too much work and the 100MB limit can be consumed in the quality of the video.
For info, the video footage looks sharp enough in iMovie '08 viewer, I can't seem to find any method to tweak the sharpness from within iMovie.
If this cannot be achieved from within iMovie '08, can the sharpness be adjusted in '06 or in Final Cut Express (which I am REALLY struggling with!), or does anyone have any other suggestions. Any idea on when the upgrade is due out?
Any help and assistance as always is much appreciated

I can't see any options from within Streamclip to sharpen the video further.
Since you are in MPEG Streamclip here (and not iMovie '08), you would have to go through the alternative "Export to other formats..." File menu option to access the original QT structure "QuickTime" option window which includes access to the built-in "Filter" options.
PLEASE NOTE: I'm focusing this particular exercise on uploading pinsharp video footage onto YouTube rather than general video editing.
While the use of different settings and compression formats may help reduce the YouTube loss of quality, IMHO there are just too many issues with both the transcoding of files by YouTube and their on-line player to justify the use of this site where quality is your major concern. Use this site when widest distribution to the most people is more important that the final quality. If you must use YouTube, you may wish to review the following Ken Stone article: Encoding for YouTube Using Compressor.

Can you encode an flv in Compressor with letterbox bars?

I am trying to encode a 1280x720 Quicktime movie to a 320x240 flv. I have compressed it 8 times already varying settings each time to get it to not squish the content to fit the 320x240 frame to no avail. Each separate setting squish the video. I believe "Padding" the top and bottom of the frame is the way to go, but the controls are deactivated when encoding an flv. I have read through he pdfs and have found no help. I even relaunched the software thinking it might be glitching up.
Any thoughts?

What version of Compressor are you using? You could transcode to an intermediate format first, i.e. ProRes or Photo JPEG @ 75% quality, and letterbox it that way, before encoding to FLV.
From http://codecs.onerivermedia.com/ - 4:2:2 Compressed Codec Formats
PhotoJPEG at its highest 100% quality setting is actually a 4:4:4 codec. When reduced down to 75%, it switches to 4:2:2 to help with the compression scheme. So why is it included here? The AJA Kona SD and Blackmagic Design DeckLink use this codec at 75% quality for its default offline compressed mode and with good reason. Virtually no banding in the gradients and average mosquito edging on the RGB colors. The compression artifacts are really only noticeable in the NTSC color bars and a little in the color filter test. And look at the x10 generation test... almost a pixel-perfect copy of the first generation! It actually passes through generations better than Kona's own 10-bit Trillions codec. Amazing! And look at that file size! Only 2.7 MB per second! That's better bandwidth (and way better quality) than DV can ever dream of. This codec truly can pass for an online codec with no problem. Best part is this codec is free to any QuickTime user, can be used on any platform and runs great even on PowerBooks.
To automate the process, you can select your job and choose New Job With Target Output from the Job menu, and add your FLV setting there.

What is better sky fire or flv for gaming sites

What is better sky fire or flv for gaming sites

You cannot play flash games on the iPad.
Skyfire only plays back video from some sites.
Any browsers claiming to play flash do so by sending the video to their computer, transcoding it to mp4, then stream it to you.

Encoding a FLV file to MP4

I am relatively new to Adobe and all of its products, and this is my first exposure to Media Encoder CS5.
Quite simply I would like to encode a FLV file to MP4. When I drag the FLV file into AME, it tells me "The source compression type is not supported."
Just curious how to resolve this or whether I am doing something incorrect. I use a Mac Laptop running OS X 5.
Thanks

Colin is right. There's a bit more information about what what kind of FLV files AME CS5 can import here. The main point is that AME CS5 and later can only import FLV files that conatin video encoded with the On2 VP6 codec.

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts Tap on the Account, then on the red button that says Remove Account.

URL encode a string before redirecting it

I want to URL encode a string before I sendRedirect it.
What must I do? I have tried this but it did not work.
response.sendRedirect(response.encodeRedirectURL("showAddAMember?century=" + country + "&stte=" + state + "&city=" + city + "&course=" + course + "&coursename=" + coursename + "&messagename=" + messagename + "&TFM=" + worker + "&admin_type=" + admin_type)); The URLEncoder.encode is deprecated so I can not use it or it is not wise to do so. What must I do to URL encode a string before redirecting it. I have written a simple method which temporarily takes care of this for me, but I want to use the accepted standard. Please somebody tell what I must do.

I want to URL encode a string before I sendRedirect
it.

response.sendRedirect(response.encodeRedirectURL

state + "&city=" + city + "&course=" + course +
"&coursename=" + coursename + "&messagename=" +
messagename + "&TFM=" + worker + "&admin_type=" +
admin_type)); response.encodeRedirectURL() and .encodeURL() do not replace unsafe URL characters; I'm assuming that's what you want happening; they're meant to encode the session id in the URL for session tracking.
Quote from http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/http/HttpServletResponse.html#encodeRedirectUrl(java.lang.String):
Encodes the specified URL by including the session ID in it, or, if encoding is not needed, returns the URL unchanged. The implementation of this method includes the logic to determine whether the session ID needs to be encoded in the URL. For example, if the browser supports cookies, or session tracking is turned off, URL encoding is unnecessary.
For robust session tracking, all URLs emitted by a servlet should be run through this method. Otherwise, URL rewriting cannot be used with browsers which do not support cookies.
Like mentioned above, use the URLEncoder.encode() ( with two params ): http://java.sun.com/j2se/1.4.2/docs/api/java/net/URLEncoder.html#encode(java.lang.String,%20java.lang.String)

Can we apply custom validation before uploading data in WebADI in 12.1.3

Hi,
I have requirement of applying custom validation before uploading data from spreadsheet using webADI. How can we do that.
Is there any way in desktop Integration Manager Responsibilty in WebADI.
I have just started exploring webADI
Please Help Me...
Thanks,
Suhani

Why are you posting this in OAF?
Anyway you can by creating a custom PL/SQL wrapper that is called by the WebADI.
Raise an application ERROR in your wrapper and it will show in the WebADI
If you just want to validated VALUES, you are better of creating an LOV on the Column. Then WebADI will do the validation work for you.

Image cropping before uploading an image

Hi all,
I am using webcenter spaces 11.1.1.8.6. I have a requirement where i need an option to crop a image before uploading it. For example before a logged in user uploads his image he should be able to crop only a certain part of the image and upload it. How do i achieve this

Well, I never tried it.But you can use some jquery plugin for this. There is no support out of the box,
try using jcrop
Jcrop: the jQuery Image Cropping Plugin
or see in this list which can work best

Previewing an image before uploading

Hi,
I would like to upload images in my application and save those uploaded images to one folder in my system, i could do that with any problem. But i have to preview the image before uploading.
How to do this in JSP or either in html?
please help me in doing this..
thanks in advance

Write the image to some temporary location in your server machine. Either public or non-public. If non-public, you could use a servlet to display the image. If the end user has somehow confirmed the preview, then just move that image to the desired permanent location.
Working with file paths isn't going to work. IE is the only browser which is so dumb that it sends the complete client side file path along with the file name. In other browsers you won't know from which client side path the image is been uploaded.

How to delete one existing file before uploading a file with same name?

Hello everybody.
I am uploading a file to Tomcat server. But, the problem is:
i want to delete an existing file in the server, if i upload a fresh file with same name. In other words, "First check for the file with the same name in the server. If it exists, then delete existing file in the server and upload fresh one". If such file doesnot exist, then upload the file to server.
I have given deleteonExit()
but, for the first time when user is uploading, i want to check for the file with same name in the server.
i am pasting the code here. please help:

Thank you MartinHilpert,
I have one more doubt,
I am uploading the file to one folder called "uploaded". Before uploading a fresh file, i want to delete all existing files in that folder. IS that possible ?? If yes, can you please tell me how to do that ??

Quicktime Pro VS Sorenson Squeeze which is better for uploading to YouTube?

I'm thinking of buying Quicktime Pro or Sorenson Squeeze - which is better for uploading to YouTube? Which would give my video better quality?
Also, with regard to Sorenson Squeeze: The website says these are its requirements - could someone explain what each of them means in logical terms?
Mac OS X system requires:
Power PC with G5 processor or greater or Intel processor - (I'll be using this program with a MacBook Pro - will this work?)
Mac OS X 10.4 or later - (Again, will this work with a MacBook Pro?)
512 MB of RAM
QuickTime 7.2 or later
DirectX 9.0b or later (What is this and how will I get it? Is it free?)
* Mac users must have the Flip4Mac plugin from Telestream (Is this plugin free?) ** Windows only feature * Plugin sold separately
Please be as specific as possible.
Thank you so much in advance for answering my questions! It is really helpful!

First.
You have no control over the conversion to Flash video (done during the YouTube upload) if you use QuickTime .mov format.
Second.
YouTube does allow H.264 Video for its "high quality" display so you would want a QuickTime .mov container.
Now you are even more confused than when you started.
Flip4Mac allows export from QuickTime (and apps like iMovie that use it) to Windows Media Player (.wmv) formats. They will also be converted to Flash Video by YouTube so you gain nothing by using it.
You don't need Squeeze, QuickTime Pro or the Flip4Mac upgrades. Just use iMovie 7 (part of iLife '08).
