Hi, I am trying play a bunch of frames as a video and for which I plan to use the exr format for the frames. For doing the same I am using ImageMagick to convert a set of dpx images to B44 compressed exr images. The problem is that the dpx images do get converted to exr format, but the compression does not happen in spite of specifying it with the appropriate command and the size of the image remains massive( DPX - 8.1 MB to EXR - 21.7 MB ). Even after performing only the conversion and without compression option specified, the size of the image is still 21.7 MB so I figured that the compression is not taking place even when its specified and after its error free execution.
My question is why are the images not getting compressed even when the compression scheme is specified? And is it normal and correct for the images to expand this much in size when the conversion of format takes place from dpx to exr. The image quality also seems to be very poor for the converted exr's. Below are the commands that I am using to convert and compress: mogrify -format exr *.dpx -compress B44 Any help on this will be appreciated and if its in terms of literal commands it will be even better.
