How to extract any picture (frame) from the video file

I am writing an application that is going to show the grid of tiles. Each tile should have picture that is frame from some particular video.
Basically something similar to Photos or Videos - standard Windows Phone app.
The question is how can i extract any picture from the video to put it as picture of the tile or button?

I pinged you offline.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined
objects and unknown namespaces.

I have had my old Iphone 5s replaced with a new one but I would like to know how to extract my old contacts from the iTunes backup? Please explain in basic english i am a beginner

Hey,
I think you will find that you have to have a debit/credit card stored on yur account regardless of whether your have iTunes Credit or want to purchase a free App. I don't know why, I assume its for ID verification or is part of the terms and conditions. I occasionally have to re-verify my credit card info even when just trying to run Update on one of my Apps or like I said downloading a free App.
If you need further clarification all you can do is contact iTunes Support:

Hope this helps. Andrew

How can I find a photo from the backup file in my pc?

How can I find a photo from the backup file in my pc?
I have accidentally erased a photo. It happened after the backup.

I am not aware you can extract a single photo or a single app's content from the backup, you can either restore the whole backup to your phone or not restore. If you restore your last backup to your phone then any content that is currently on your phone will be replaced with what was on it at the time that the backup was made - so if you do decide to restore, first copy off any purchases to your computer's iTunes via File > Transfer Purchases, and copy any documents/files that you've udpated on the phone since the backup.

How do i export a single jpeg frame from a video file in final cut x

how do i export a single jpeg frame from a video file in final cut x

You can also use the 3 finger method of COMMAND+SHIFT+4, then drag across what you want to copy from the image. That will show up on your desktop, which then you can edit using Photoshop, if you want too.
You can then change the file format from a PNG to either a .JPG or TIFF or even a Photoshop image.
Make sure, you have stopped the playback, to what you want to save as a still.
Either method works, to make a still image from video.

How to Extract data and reports from the SAP BW warehouse

Hi to All Guru's
I am new to SAP BW. Can any one help me to know, How to Extract data and reports from SAP BW. Do we use any tools. After Extracting the data from SAP BW how can we move all the data to Cognos. It would be kind enough to provide me with any documentation or links. Step by step procedure would be very much helpfull to me.
Thanks
Venu

Hi Voodi
Thanks for the quick response. I think Open hub is to extract the data from SAP BW, but what about sending this data into Cognos. Can you please let me know in detail regarding answer. If possible send me any documentation or links regarding this. Thanks for your concern.

After rotobrush, how to make background picture appear in the video when exporting it to PremierePro

I seem to have problems saving/using it with premiere pro. it's a 10 second video of myself with 3 pics: 2 that I put in front of the video and one as a background. In after effects, in the bottom left corner box, the 2 pics are above the video file and the background picture is below it. Still in after effects, the background pic is there behind me and the 2 other pictures are in front of my video which is where everything should be, great. When i save it, then export it to premiere pro, the 2 pics in front are there but not the background pic, the background is just my full video as if I didn't rotobrush it. Help??
Also, how can i export the project as a file in Avi, mpeg, mp4...?
Thanks in advance

Hello Mylenium, i do apologize about my ambiguous question. I'm starting to learn how to use it and in some way, i didn't even know what i was talking about myself. But thanks to your help, i now got it.
"When you export an After Effects project as an Adobe Premiere Pro project, Adobe Premiere Pro uses the settings from the first composition in the After Effects project for all subsequent sequences. Keyframes, effects, and other properties are converted in the same way as when you paste an After Effects layer into an Adobe Premiere Pro sequence."
so as it says above, it only uses the initial video. What i did was only render using the rotobrush and i didn't "render queue" the whole project afterwards simply because i didn't know i had to do that. I thought rendering it from rotobrushing it and adding the background effects would be enough.
Again, thank you. and i also learned how to save it in different format, since AVI outputs a huge file size.

Hi please tell me how can I remove picture frame from lock screen

?

You can only turn it off if you have a passcode on the lock screen - in which case you do it via Settings > General > Passcode Lock > Picture Frame off. If you don't have a passcode lock then you can't disable it

Hi,
I have a jpeg movie file 60 mins long and a text file tell me five time-lines for breaking the movie. For example, break the movie at 10:21, 16:05�
The final output should be five small jpeg movie files. Each file contains a 90 sec (30 sec before the break time and 60 sec after the break time).
Do you know any java library (jar) contain the library that can help me on programming this? Any existing source code? Any SDK for a movie editor can do that?
Please help.
Thanks
Kenny

How do I remove an entry from the "Store Files" drop down list in the "Import Settings" section of Aperture 3.3.2

The dropdown list "Store Files" in the "Import Settings" section of Aperture 3.3.2 displays the history of the entries previously added to the list. Some of the entries are no longer valid and I'm trying to delete them but I can't find a way to do this. This is a screenshot. Does anyone know how to do this?

Once again - the Jive system ate my bullet points and messed up the formatting
Is the MacOS X version in your signature correct? Then you cannot be using Aperture 3.3.2?
You should not be seeing duplicate entries in the "Store Files" pop-up menu. This looks like your Aperture Preferences file is corrupted and needs fixing.
Quit Aperture (and log off and on again, if you are running MacOS X 10.7 or later)
Then reveal your User Library (from the Finder's main menu bar, the "Go" menu. Hold down the options-key until the library apears in the drop-down menu)
In the Library folder select the "Preferences folder and locate the file "~/Library/Preferences/com.apple.Aperture.plist"
Now you can either
remove the com.apple.Aperture.plist file to the Desktop, to force Aperture to create a new one, but you will have to set again your Preferences from the "Preferences" panel,
or make a backup copy of the file and edit it, if you are an experienced programmer and have Xcode installed. To fix the drop-down list you need to edit the item "RecentReferenceFolders" and delete the redundant folder names. Enter "recent" into the search field to find it quickly. If you click an item in the list, plus/minus buttons should appear. But only try this, if you know how to edit property lists, otherwise it will be much safer to delete the faulty list and to set your preferences again from the "Preferences" panel.

Extra a Picture frame from an iPhone Video

I have several videos where I would like to extract a picture frame from each video and to place into a Digital Photo Frame. I am not sure if I am making my request to the correct discussion Group, but I needed to begin somewhere. I am using a G5 iMac desktop with OSX 10.4.11. I am wondering if this can be done and can anyone explain how this can be accomplished?

use iMovie or Quick Time Pro - or other video editor is you have one - that is not a feature of iPhoto

Print Out Still Frames From HD Video

I am importing HD video into iMovie 08. I have made a few still frames from the video for printing. I could not export them to iPhoto or Photoshop Elements 2.
How can I make HD video prints? Do I need new software?

I have made a few still frames from the video for printing. I could not export them to iPhoto or Photoshop Elements 2.
Select the "still frame" sequence and use the "Reveal in Finder" option to take you to the saved "still image" in the named_Project package. If you then double-click the image, it will open in Preview. Using Preview, you can print the image or save it to any of the available image formats in any "visible" location for later access by whatever graphic application you wish to use.

Can I rip the audio from a video file?

I have a video file with a band singing on it. I have an ipod nano, so I can't import the video with the singing onto my ipod. Is there anyway to rip the audio from the video file and put that onto my ipod?
-Thanks

Open the video in Quicktime Player.
Select the Export menu item.
Change the Export type to "Sound to Wave".
Save the WAV file somewhere with the default settings.
Load the WAV file into iTunes and use iTunes to convert it to AAC for the Nano.

I created an album in iPhoto and every time I click on slideshow it plays the pictures backwards from the order in the album. How do I change that?

I created an album in iPhoto and every time I click on slideshow it plays the pictures backwards from the order in the album. How do I change that?

When running a slideshow from an album it will not run properly if the photos are sorted manually. Sort them by any of the other options, title, date, rating, etc. and it will play correctly.
Send a report of the problem to Apple via http://www.apple.com/feedback/iphoto.html.
If you must sort them manually create the slideshow in the slideshow mode in iPhoto, not from an album.
