video - Matlab: using avifile, addframe, getframe; the generated avi is contorted -

i'm training machine learning algorithm, , wanted make avi visualize appearance of weights on time. threw similar to:

aviobj = avifile( 'weights.avi' ); jj = 1:whatever   % training   imagesc( ... ); % '...' stuff reshape weight matrix   aviobj = addframe( aviobj, getframe ); end; aviobj = close( aviobj ); implay( 'weights.avi' ); 

the problem is, frames end looking this:

the numbers shouldn't have orientation. occurs avi generate in matlab.

any suggestions?

finally had time this. problem due axes. when using image or imagesc, tacks on black border line on bottom & left of image. when use getframe, grabs image data plotted, sans black lines. however, frame larger image data.

the following solves it:

aviobj = avifile( 'weights.avi' ); fig = figure; jj = 1:whatever   % training   imagesc( ... ); % '...' stuff reshape weight matrix   axis off;   aviobj = addframe( aviobj, getframe( fig ) ); end; aviobj = close( aviobj ); implay( 'weights.avi' ); 

setting axis off fixes it.
