Shifting aspect ratios for IMAX, can they not?

[Coenskubrick]

You know what I mean, they shoot all the Imax stuff in Imax but then go shoot the rest in 2.35:1. WHY do they do this? It's so irritating. Nolan is the biggest perpetrator. If you want to fill up the vertical space for IMAX stuff why would you not want to for the rest of the film?

IMAX cameras are expensive. The film is also very expensive, and the cameras make a lot of noise. It is considered impractical to shoot an entire movie with an IMAX camera, hence the shifting aspect ratios.

This, plus the whole point of IMAX is to enhance the spectacle of certain sequences by giving them a larger-than-life quality; you lose this effect when the entire film is presented in IMAX aspect ratio rather than just select portions expanding to fill up the entire screen.

While I don't let it bother me too much, I do find the shifting aspect ratios kind of annoying. I'd rather the entire film be in the same aspect ratio, even if only certain scenes are filmed using Imax cameras.

It really doesn't bother me at all. In fact, the first time that I actually noticed it was in Hunger Games: Catching Fire. And it was done brilliantly!



That transition is epic.

All they have to do is not shoot anamorphic. Unless you're watching it in true IMAX (which is taller than a regular screen), a regular 1.78 or 1.85 ratio will make the segments line up to the viewer.

That does look epic, but most of the time it just seems to cut in and out of IMAX footage arbitrarily.

I personally love it, as long as the IMAX sequences are shot in IMAX. The great cinematic experiences were Interstellar, Dark Knight Rises, Skyfall (not shot in IMAX) and Hunger Games 2.

I know the new IMAX is not the same as the 70MM but I still think it is best experience possible outside of the home.

Personally I think it is just a symbolic way of saying "it won't be long before the entire film is filmed that way".

Or it won't be long before 70MM and IMAX technologies merge.

Have no idea about this imax stuff.

I was watching Interstellar 4K up scaled & when ever the imax scene appeared it blew the crap out of any image I've seen on BD period. I went back & then looked at the compression. To my surprise the MB/S didn't jump at all when going from 2.39 to 1.78.

So space ain't an issue..

Why can't they release both a 2.35 & IMAX only version BD?

[Spike M.]

There was a pretty big online uproar when M:I4 wasn't released with shifting ratios. Big enough that it drew Bird's attention on twitter. Can't win.

I can't imagine watching TDK/R or Interstellar entirely in 2.40. After seeing Interstellar in 15/70, I was barely okay with the crop to 16:9. Clearly, that's the frame Nolan intended for home viewing, though.

Long live the intended aspect ratio.

[antennahead]

Not that my opinion matters, but I too hate switching aspect ratios in a film.

[AmishParadise]

I own a 150" 1.78:1 projector screen and use black velvet masking, horizontal masking for aspect ratios north of 1.78:1 and vertical masking for aspect ratios south of 1.78:1. The end result, a black hole surrounding the visible image area.

Not interested in leaving large portions of my projector screen unmasked, because for a few minutes during a scene or two in a scope film the aspect ratio opens up and is taller. It's not worth the trade-off for me.

My solution, using BD Rebuilder I re-author the given Blu-ray creating a version with a fixed aspect ratio, i.e. enabling the "Use AVS Filters during encoding" option adding the command to crop each frame down to the widest of aspect ratios used followed by the command to add the black bars back to the given frame.

It's better just film every movie at 1.78:1 like avitar. 2.35:1 not using all part of the screen both in theaters and TV.

Better for whom?

[JohnCN]

Shifting aspect ratios may be OK on a projection screen or very large screen TV viewed from a close distance. However, those of us with 2.35:1 screens like me are frustrated because we have to view the movie with bars at the top AND sides except during IMAX segments when the image reaches the top and bottom of the screen. It seems the disc production companies care somewhat about us because captions are within the picture frame. So why not offer two versions of the movie on the disc or separate discs. Christopher Nolan films and my latest acquisition, Top Gun Maverick I just found out today, shifts from 2.39:1 to 1.85:1 (approximately).

I just watched the Blu-ray the other day. Well, I re-authored the Blu-ray first using multiAVCHD. Re-encoded the video cropping each frame down to 2.39:1, then adding the black bars back in the process. No more shifting aspect ratios.

Thankfully my latest JVC projector gave me back a cropping feature that I had on my old 3 gun SONY CRT 5 upgrades ago.

Back then, it was useful to crop out Japanese subtitles in the black bars of Laserdiscs (The Phantom Menace). Today, it allows me to completely eliminate the abomination that is shifting aspect ratios. As a guy that individually and perfectly mattes each presentation ( Lens memory and side panels ), this feature is invaluable to me.

I created a short video last night of my physical projector screen masking in action for those interested in checking it out. I started playback of my custom 2.39:1 presentation of "Top Gun: Maverick" advancing to Chapter 3 and pausing the video, then moving the masking into position. I left a few lights on when taking the video so it was easier to tell what was going on.

Screen masking. (1.78:1 to 2.39:1)

(Hit up the link in my forum signature to learn more about my DIY projector screen masking. Nothing beats a true black hole surrounding a given presentation, black bars projected on a white screen need not apply.)

I don't mind shifting aspect ratios. I'd even say I like them. It's recreating the experience of seeing the film in the theater. It adds a certain "wow factor" to those special sequences that are opened up. Especially for 3D. Last week I watched the first two Guardians of the Galaxy films on 3D Blu-ray and I had forgotten about the shifting ratios. It looked awesome! Both films also have frame breaking effects when in the scope ratio. Later Marvel 3D Blu-rays like Infinity War and Endgame do not have the IMAX scenes unfortunately.
