is it possible to make frames to video

Asked by Elysi Cochin on 26 Feb 2013

i have a video.... and when i convert it to frames i get 1000 frames.... now is it possible to select frames from 500 to 700 and save it in avi format..... so that i can open the video later without running the code as the video we gave for input...... please do reply...

yes only read your matrix from b=a(500,700)\ now save your b variable

Is your video live/streaming, or has it already been captured and saved to a file (from which you wish to extract a subset of frames)?

Accepted answer

ya.........using getsnapshot

FRAME = getsnapshot(v) immediately returns one single image frame, FRAME, from the video input object, v.

sir i got a code from the following link

and i edited it as below but i'm getting error

    for frame = 60 : 100 
        outputBaseFileName = sprintf('%d.jpg', frame);
        outputFullFileName = fullfile('Frames', outputBaseFileName);
        I = imread(outputFullFileName);
        data(:,:,:,i) = getsnapshot(I);   

my error is

    ??? Undefined function or method 'getsnapshot' for input arguments of type 'uint8'.
    Error in ==> VideoMainTrial at 32
        data(:,:,:,i) = getsnapshot(I);

please rectify it for me sir....

Your "I" is not a video input object.
