MATLAB: Getframe too slow

Slowing down the animation to 10 frames per second should allow you to use "getframe" and have it include all the frames. Then, when using "VideoWriter" to create the video, you can specify the 'FrameRate' property.

For more information, please see the following links:

MATLAB: Movie resolution using getframe

Notice the third option for writeVideo:

writeVideo(writerObj,img) writes data from an image to a video file.

So create an image and then display the hi-res ( not HD because HD is only 1080 lines tall) image, and then call writeVideo(). I haven't tried it but it claims that it will write out the image, which can be any resolution, as opposed to currFrame which can only be as large as your monitor.
