Are there any lossless codecs for video that OpenCV support on Windows? If there are any such codecs, what are their 4 character codes like in CV_FOURCC('M','J','P','G')?

Are there any lossless video codes except RAW format? I'm not en expert, but I've never heard of such codecs... BTW, do you know that you can provide -1 as an argument, and OpenCV will show you a window to choose the codec.

@Kirill When you pass -1, it does not list all of the available codecs.

There are lossless (VfW) codecs for Windows that you can install, but I am not sure OpenCV will accept their FourCC. They may also be a bit finicky about the input image format and size.

Alternatively, you might consider saving PNGs (or GIFs for gray images) instead of videos.
