Hi all,
I am trying to make a movie from a set of sequential images using the code below.
However I am getting an error message:
"Error using im2frame
Indexed movie frame must have a non-empty colormap"
"Error in movie (line 13)
writeVideo(writerObj,im2frame(Frame));"
Please is there some words i forgot to add to the line13?
Thanks for your help in advance
ImageFolder = ('C:\Work\2015 CA\Contour\Von Mises');
TiffFiles = dir(strcat(ImageFolder,'\*.tiff'));
S = [TiffFiles(:).datenum]
[S,S] = sort(S);
TiffFilesS = TiffFiles(S)
VideoFile = strcat(ImageFolder,'\Video');
writerObj = VideoWriter(VideoFile);
writerObj.FrameRate = 10;
open(writerObj);
for t= 1:length(TiffFilesS)
Frame = imread(strcat(ImageFolder,'\',TiffFilesS(t).name));
writeVideo(writerObj,im2frame(Frame));
end
close(writerObj);

Thanks all for your inputs. i was able to solve the issue by replacing the 'FOR' loop with the lines below:
for t= 1:length(TiffFilesS)
[Frame,map] = imread(strcat(ImageFolder,'\',TiffFilesS(t).name));
if ~isempty(map)
FramedImage = ind2rgb(Frame,map);
end
writeVideo(writerObj,im2frame(FramedImage));
end

Hi,
Reading the error message there is an error when you are using the function im2frame, which is called on line 13.
What are you passing to the function in2frame?

This is all demonstrated in well commented detail in my attached demo. Pay particular attention in the latter half of the demo where I create frame and colormaps.
