Yes this idea sounds the most practical with a QR frame sequence. Technically cracks or keygens could have their binary data distributed in the video. And if that data were encrypted with AES whose key was a hashed password then it would be secure even. Though it's not stealthy in that it is obvious data is hidden in the video. I was thinking some color channel manipulation to do the QR might be possible. After all, something like gridlines with slightly faded colors would be highly visible to a computer vision algorithm but nearly imperceptible to a human.
QR code sequence with minimum frame holding to ensure lowered frame rates don't cause an issue. Plus using color channels in a clever way instead of black and white. Not to mention some encryption just in case. That's an interesting encoding and decoding tool to have for sure.
