I wonder if AVC soft-telecine has ever been used for Blu-Rays.
Thanks, but that was just a clip I provided for someone who asked to see an example of telecined AVC content with some horizontal movement. It's hard to tell anything from that clip in terms of judder or sawtooth & moire interlacing artifacts, because the camera isn't panning and there are no angled straight edges in it.

Here are the two scenes I've been using for reference (they are both from the same episode so they are both in a single video clip):

The first scene has a camera pan which is good for watching for judder, because it's easy to see by watching the edges of the picture frame on the wall and the lamp shade. The second scene is the car pulling into a driveway scene that I mentioned before. On my BD player there are prominent sawtooth interlacing artifacts on the car's chrome trim on its hood and top of the door when the car or camera is moving (or in the case of the soft-telecined / fake-interlaced / piped through x264.exe encode I did, the prominent sawtooth effect remained even when both the car and camera were stationary).

I didn't include the scenes which show a lot of moire on one of the actor's shirt collar, because I didn't want the clip to be too long. It's already 50 seconds long as it is.

By the way, this episode, along with all of the newer episodes starting in the late '80s, is 16:9, which annoys to me to no end, because they were originally broadcast in 4:3. At least they left the 1970s episodes (like in my clip from post #15) in the correct 4:3 aspect ratio. In any case, I've been letter-boxing the 16:9 ones (scale=704x360:flags=lanczos,pad=720:480:8:60,setsar=sar=10/11) instead of doing anamorphic 16:9 encodes, because anamorphic 16:9 has no benefit whatsoever over letter-boxed 4:3 on my type of TV, but they end up having a significantly bigger file size because you're encoding 704x480 picture information rather than 704x360 picture information.
