For me, incorrect playback speed is a deal-breaker, so I’m really frustrated to see the BBC go down this road with global masters for 4K so far. At the right speed, I’d buy dozens of 4K releases from them, but the way they’re doing them now, not a one.

Are you comparing to NTSC DVDs?

The aliasing has always been there even in 576i SD. That's the film effect from before they were shooting in native progressive scan. Resampling to 480i is likely softening that down at the expense of what (little) fine detail it has.

It wasn't done on film. I believe the effect people are talking about is from deinterlacing the original 576i50 tape footage to 576p25

As I said, film effect.

There was some genuine film material however. The slow motion footage of the monks in Tooth and Claw was on film, and you can tell the difference.

Fair enough. All I know is it's not noticeable on the DVDs and is VERY noticeable on the BDs. Flip that and reverse it for compression.

The new Doctor Who series could be visually interesting if they are shooting with 4k in mind this time. They certainly are going with a more cinematic look if anything and using true anamorphic lenses with a wider aspect ratio.

They are shooting with these chaps behind those anamorphic lenses. http://www.arri.com/camera/alexa/cam...n/xt_features/ http://www.arri.com/camera/alexa_min...res_alexamini/

4k, through 3.2k down to 2.8k is the lower end for those combination of cameras, so a very worthy 4K iteration would be possible. Depends what they finish at though. I'd hope, even if effects are rendered in 2K for cost reasons, they master at 4k and upscale the effects. ArriRAW format also allows excellent HDR grading options if they are using that, but I think that's 2.8K max. which is still a great starting point for UHD.

OK, so we haven't really a clue yet exactly what they are doing, but time will tell and at least whatever they do, there's good grounds for 4K HDR even if some or all is upscaled. Twice Upon a Time shot with a different set of cameras still looked great and I think these are superior technically.

StingingVelvet · 10-14-2018, 10:09 PM

If they finish at anything higher than 2k I'd be shocked. Even Game of Thrones finishes at 2k. However UHDs would still look great.

My US S1 blu-rays came today and I just did a comparison between the DVD and blu for the first 3 minutes or so of Rose. Nice clean updated text on the menu and titles on the blu but I see what you're saying about the aliasing. There doesn't seem to be that big of an improvement in the image and even the audio is the same (DIA seems mixed too low on both but that could just be this part of this ep.) At this point which version I watch depends on what packaging I want to deal with: The plastic slip digipak or the amaray with floating tray (the clips that hold the tray were completely broken off when I opened it so I need a new case.

)

Watching both just makes me so grateful they switched to 1080 and are now 4K capable.

StingingVelvet · 10-16-2018, 02:47 AM

For the record I do slightly prefer the BDs because the compression can really be nuts on the DVDs, but I was just trying to be informative for people that it's a much closer race than it should have been.

Also I put the BDs in the DVD packaging. Love them booklets, and the BD packaging looks odd on the shelf next to the Matt Smith boxes.

How is the UHD?

ditcin · 11-08-2018, 02:51 PM

Please, state the running time - it it's a longer version than what aired?
Thanks.

Yes, but only by 4%.

Is it in 24Hz refresh rate? Does the BD come in 1080p or 1080i?

Why "sadly"?
Also, I thought BBC content was 1080i

Sadly because the show was created at 25fps and the BBC chose to slow it down instead of convert to a compatible interpolated frame rate so it can be viewed at the correct speed.

Much of it is, but not all.

So this on Oled will display some major judder, correct?

No, the episode is slowed to proper 24fps and OLEDs play that correctly.

And the HDR looks beautiful on this disc. One of the standout discs in my collection, honestly.

I want to get this, but I think I should first start watching from series 1 just to get familiar with this universe
