Sorry I'm late catching up on this post/thread.

Are this captures 1080/HD? The 30fps then must be interlaced. You should be able to de-interlace it and have it look great. The 24fps is full frame-by-frame (not interlaced) but probably doesn't have it's internal flag(s) set to 23.97fps. There should be software which can run through the file and update just the flag(s).

(If it can be conveniently done, would you post a 5-consecutive-frame strip (full-sized & starting from the same frame) from each capture? I'd like to check out the captured differences, especially the odd color change.)

Sorry to burst your bubble guys but Netflix is only doing FOTR in 480p.

No, it is available on Netflix in full 1080p. But you're right that under certain scenarios, you'll only see it in 480p. Google Chrome, for example, is limited to 480p on certain titles. But if you watch it in Edge, or on a Roku or Apple TV, then it will be full 1080p. We've already talked about this earlier in this thread.

Anyway, as an update, I've been attempting to capture it again now that it just returned to Netflix, but I'm still having the same problems. My capture device is capable of recording the native 23.976fps, but it's my Roku that outputs the incorrect framerates. My Roku 3 can only output 30fps, and my Ultra can output 24fps, but for some reason the image is super dark. Does anyone know of any streaming boxes that output true 23.976fps, or can do 24fps without color shifts?

To be more specific about the framerates I'm able to capture with my Roku boxes, here's what I'm able to do: 1080p60i and 1080p30p on my Roku 3, and 1080p24 on my Roku Ultra (but the colors are super dark on the Ultra). I don't think any of these are ideal for a preservation. I need a streaming box that won't produce a color shift, and can record at 1080p23.976. Any leads?

A few thoughts:

- Have you checked whether you actually get duplicate frames when recording at 24p? It's thinkable that it does record 23.976 frame-by-frame and merely writes it down as 24p in the metadata, in which case you could just change the framerate and have the stream in good condition.

- If you record at 24p, you should, in theory, only get duplicate frames every now and then. To be more precise, I think you would get 1 duplicate frame roughly every 40 seconds. You shouldn't have any frame drops, since the source would be "playing slower" than the capturing device. *At least*, that is what my brain is concluding at this moment, feel free to point out errors in that reasoning. But if that is correct, then, with enough patience (or a good AviSynth script) you should be able to eliminate those duplicate frames and end up with a good recording.

- You could always get one of those professional capture things they use for recording camera output in the field. They take a HDMI/SDI stream as-is and just encode it in DNxHD/ProRes/something and save it.

I'm looking into it. The main issue with the 24fps recording is just that it's really dark for some reason. I haven't figured out why the Roku Ultra outputs so dark. I wouldn't want to capture something and then have to regrade the whole thing. I'd rather capture it without a color shift. The 30fps and 60fps recordings at least have the correct color, I just think the framerates will be an issue. But I'm looking into it to see what I can do.

If anyone knows of any streaming boxes that output Netflix at 23.976fps (or even 24fps, I guess) that doesn't produce an ugly color shift, I'd love to know.

And I actually have a professional capture device and have been capturing in ProRes. The capture device isn't the problem, it's the streaming box that's the issue.

Also, here is a link to some short sample clips of each recording, if anyone wants to look at them. I've included one for all three settings: 1080p24, 1080p30, and 1080i60 https://goo.gl/GYKGzp

Quick update: It's looking like both the 1080p30 and 1080i60 footage will convert cleanly to 1080p23.976. The 1080p24 footage is super wonky though, and doesn't convert well for me. The frames don't line up with the official Blu-ray. So I think tonight I'll try capturing the entire film in 1080p30 and see how it works.

Ok guys, I completed the capture and synced it to the Blu-ray. It isn't perfect, but overall I think it's still an improvement on the Blu-ray. Feel free to PM me if you want it!

A few things take note of:
-It has more detail than the official Blu-ray because of the lack of DNR
-BUT, it still suffers from some minor compression artifacting due to the fact that it's recorded from Netflix. I've hidden a little bit of the artifacting by layering a subtle amount of grain (it basically replaces the compressed-looking grain from the stream).
-The 60i to 24p conversion wasn't perfect, and for some reason the converted video had a little flicker on the very top and very bottom of the frame, so to compensate for that I cropped the top and bottom by 2 pixels each.

If someone has the hardware to do a true 23.976fps capture, please still do it! Otherwise, I think mine is pretty good for the meantime. (Again, feel free to PM me if you want it).

Could you post some BD/Netflix comparison shots from later in the movie? Say, for example, the Council of Elrond.

I'm asking because I've compared the BD to the HDTV capture (which appears to be the same as the Netflix rip) and I can only see a difference in the above scene with Gandalf and Bilbo as well as the scene where Gandalf and Saruman try to out-Wiz each other. As far as I can tell, for all other scenes in the movie, the BD has equal or more visible grain to the capture. I don't know why they would DNR just those two scenes for the BD but that seems to be the case.

mmmmmm
