am constructing video from frames... now i delete a frame... but then also i need to construct video from remaining frames... it can be the first frame i'm deleting or last frame or any other frame... still it must construct video with the remaining frames...
please help me with what modification i need to do here.... please reply...
here's the code i used to construct video when all frames are there..
for frame = 1 : numberOfFrames
outputBaseFileName = sprintf('%d.jpg', frame);
outputFullFileName = fullfile('frame', outputBaseFileName);
% Read the image in from disk.
thisFrame = imread(outputFullFileName);
% Convert the image into a "movie frame" structure.
recalledMovie(frame) = im2frame(thisFrame);
end
% Create new axes for movie.
fontSize=14;
figure;
set(gcf, 'Position',get(0,'Screensize')); % Maximize figure.
axis off;
title('Movie recalled from disk', 'FontSize', fontSize);
% Play the movie in the axes.
movie(recalledMovie);

Just change your for loop to start with the frame you want to begin with:
for frame = beginningFrameNumber : numberOfFrames

outframe = 0;
for frame = 1 : numberOfFrames
outputBaseFileName = sprintf('%d.jpg', frame);
outputFullFileName = fullfile('frame', outputBaseFileName);
% Skip this file if it does not exist.
if ~exist(outputFullFileName, 'file')
continue;
end
% Read the image in from disk.
thisFrame = imread(outputFullFileName);
% Convert the image into a "movie frame" structure.
outframe = outframe + 1;
recalledMovie(outframe) = im2frame(thisFrame);
end
