Converting a .tiff sequence to a .avi video file

Hello everyone,

I collect uint16 arrays from .tiff images.

I want to convert these images uncompressed to an .avi video-file.

Does anyone know how to do this?

Kind regards,Dries

Dries - consider using the VideoWriter object. A couple of very basic examples can be found at the given link or at writeVideo, but you should be able to extend them for your purposes. For example,

 v = VideoWriter('newfile.avi','Uncompressed AVI');
 open(v);
 for k=1:10      % assumes 10 images to write to file
     writeVideo(v,randi(255,100,200,'uint8'));
 end
 close(v);

I tried to use this sort of code myself before.

But I keep getting the following error message:

IMG must be of one of the following classes: double, single, uint8

Try converting to a double. Perhaps something like

 maxUint16Bit = 2^16 - 1;
 v = VideoWriter('newfile.avi','Uncompressed AVI');
 open(v);
 for k=1:10      % assumes 10 images to write to file
     img = randi(maxUint16Bit,100,200,3,'uint16');
     writeVideo(v,double(img)/maxUint16Bit);
 end
 close(v);

im2double() your image before the writeVideo

Right! I thought that was only in the Image Processing Toolbox but it looks like it now is part of the core app. I really should upgrade from r2014a!
