Before you start rolling this into a video codec, please consult the sources of UT Codec, which has been state of the art in this space for many years. Or, at least, use UT Codec as a direct basis for comparison, to see if you are beating it in terms of compression/decompression speed. Modern lossless video codecs don't care that much about saving space, since you're burning gigabytes per minute anyway; the key is that the compression and decompression are as transparent as possible, to reduce the bandwidth to/from the storage medium. A good lossless codec can be used to scrub through and edit on a video editor's timeline, so decomp performance is what's most important. Also, any such lossless video codec is going to need more than 8 bits per component; most real-world footage coming off of phones and cameras is 10-bit Rec.2020. If it is too difficult to position QOI for real-world sources, you can certainly keep it 8-bit and market it as an animation codec or similar; just keep it in mind.
