I watched the video a while ago, and thought is was pretty moronic, and clearly created with an agenda. In other words it is biased as hell. Anyone that can’t distuinguish between altering a sound mix around the time of release, and adding in CGI effects decades after the fact, I’m not going to take too seriously. I personally believe it is actually not that cheap to recreate the OOT. The negative is conformed to the SE, and the original pieces of negative as well as the original elements that were replaced are likely in pretty bad shape. So, I would say restoring the OOT would likely be similar to the Coppola restorations of the Godfather trilogy. It would be a restoration based on many different sources of varying quality and would require a wealth of expertise including the people involved with the creation of the originals to get it right. I also don’t believe releasing the OOT would be hugely profitable. The market for physical releases has shrunk considerably, becoming a niche market for videophiles, and the group of people that grew up on the OOT are going the way of the dodo. So, the main motivation of restoring the OOT is to preserve the original 70s and 80s film experience for posterity. These films in their original form were hugely influential, and it’s a shame, that it can no longer be seen in the best quality warts and all.
