Capture Pictures/Images from Video

Hello All,
I am just getting warmed up in these forums here. I wanted to know if you could capture still images from video clips and if they are Kodak clear. I have a couple of family videos that I would like to have pictures taken from and framed. Does anybody know much about this?

<[email protected]> wrote in message news:[email protected].. > Thats interesting. I had talked to a representative from Adobe and I was > told it would be crystal clear of a photograph! That includes after the > image being deinterlaced... It will be "clear." However, the clarity of a picture is a function of the original video and the resolution. Standard definition digital video is 720 x 480 pixels for a total of 345,600 or, roughly, 1/3 of a megabyte. This is very low resolution compared to what a good digital still camera can produce, i.e. 4-8 megabytes. A high-definition frame will contain 1,920 x 1,080 pixels, totaling 2,073,600. A 2 megabyte frame will produce a reasonable 4 x 6 photograph.

Raspberry Pi B+ capture a image from a video cam

Hello,
is there any way to capture a image from the video camera. I didn't find any media class for video. Nor did I find any Runtime.exec to use a native linux command.
Did I overseen something?

Hi Klaus,
There a few ideas in design stage, but nothing solid enough to talk about. And actually it should not have been possible with older ME as it's specifically prohibited by the spec. I mean native methods in Java applications. Of course there may be other means to communicate with native applications, like files, sockets etc. But no direct calls
The date for ME 8.1 GA (General Availability) release is not confirmed yet. But it should happen quite soon, stay tuned

How to capture an image from a clip

Hi,
Is there a way to capture an image from a movie clip using iMovie 06?
I would like to save some frames from the vedio footage as photos.
Any help will be greatly appreciated. Thank you.

Hi iMac User:
Yes-you can save a single frame from iMovie by selecting the File-->Save Frame As option. From there it will ask you where and in what format you want to save it.
Just be aware that the quality won't be perfect because it is taken from a video clip.

How Can I get rid of a download, it won't stop processing? Even after I have deleted image from videos?

How do I delete a download as it won't stop processing? I have even deleted the image from videos but it is still in my download saying processing. Help?

Hi Sanjampet,
Yes, it was a folder from a website. It was a backup of a website (the website was hacked into at one point if that matters). I kept the backups in a folder on my laptop. I was able to delete the other backups, but this one was giving me an issue for some reason. The other day when I was having this issue and you were trying to help me solve it, it was showing that I only had (about) 158 GB of memory left on my computer, but when I was finally able to delete the folder and all of its content it was showing that I had over 250 GB of memory left. I don't understand how a website's backup folder can be that large :S Was that why I was having so much trouble doing anything with it?
I could drag the entire folder into the trash can, but if I tried to empty the trash it would just do what was showing in the picture from my original post
Thank you so much!

How do I capture good stills from video on Photoshop Elements 8?

I'm using Photoshop Elements 8. When I try to capture still photos from video clips, the results are not very satisfactory. Usually the stills are very unclear, not sharp like I want them to be. I have to make many attempts to capture a still before I can get one that's halfway clear.   Does it have to be this way?   What can I do to get consistently clear stills from video? Thank you!

Fair enough, Barbara. Thanks!

Frame from Video is more or less a legacy feature in PSE 8. It was meant to capture a frame or two from a short homemade video at a low resolution. It doesn't do HD video at all, and isn't meant for a clip that's more than a minute or so in length. It's been dropped from the latest version because nobody has those kinds of movies anymore.
So the bottom line is you're better off doing this with some other program than with PSE.

Question about taking Images from video in FCP

I just recently upgraded from pinnacle to FCP 7 and am loving it. My question is when I try to take a still Image from video using Quick Time Conversion, the image comes out blurry or with bars around the edges of people. At first I thought It was because I was trying to capture a moving Image, but then I tried it with someone standing still and I ran into the same problem.
I shoot with a Canon XH-A1

Take the exported file to Photoshop and use Image Size to correct the aspect ratio of the image. Apply the Deinterlace filter in Photoshop to remove the interlacing.

Create still images from video files?

from http://gadgetwise.blogs.nytimes.com/2009/04/16/5-new-photoshop-tips-for-photographers/ , "You can now preview video in Bridge and create still images from video files."
I just installed the 5.4 Camera Raw Update.
I can preview the AVI files from my Nikon D5000, but have not figured out how I might create a still image ( other than stopping the movie, and dragging to copy ) Have tried searching adobe, this forum, have not found more info ion this.

Stop the video at the desired point, press the Shift, Command, and 4 keys, drag the cursor so that the whole picture is highlighted, let go of the button, and open the PNG on the desktop.

How to change the path of sysprep files that were copied to reference computer when i capture the image from reference.

Dears ,,
how to change the path that sysprep were copied to reference computer when i capture the image from reference.
Should i modify some codes in LTIAPPLY.wsf? how to modify it?
Thanks.

Sysprep and capture has *Three* steps.
1. Run sysprep on the local machine (easy).
2. Copy WinPE down to the local machine so we can reboot into winpe for capture.
3. Capture the drive in an *offline* state from within WinPE.
What is most likely happening is that you are having problems with step #2. 100MB is *WAY* too small to copy down WinPE. By default MDT will make this System partition much bigger, 499MB. IF you install Windows 7 from the default media. IT will only create
a 100MB partition.
By default MDT 2012 Update 1 and greater *should* recover to a fallback drive with the OS on it, however if you are running older versions that might not happen correctly.
If you are still having problems, copy your BDD.log file to a public share like OneDrive and copy the link here.

No, AIR has no direct support for video capture. But it can
access the webcam.

Re: Capture the Image from a video file

Thanks a lot. But when I view the program in the thread, it seems that it needs to some program code is to play the video first and then the image can be captured. Is it possible that even I don't write the code for playing the video first and just write the captured code so that can still capture the image by using Java only from the exists video file. Thanks a lot.

Thanks a lot.You can get away without playing the video by seeking to the frame you want using FramePositioningControl ( [example here|http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/solutions/Seek.html] )and then capturing the frame using FrameGrabbingControl (similar to the code I posted). But still you would have to load the video file, create the player using url, realize the player, perhaps prefetch it (all in the link I have given above) then you are ready to seek to particular frame and capture it. But now you don't need to actually start the player so that video/audio is visible/audible.
Thanks!
