THE DARK KNIGHT RISES: 1.43/ VAR IMAX Edition (10 minute test render available)
Time

So this is a quick little fan project I was inspired to make after watching a fan restoration of The Dark Knight’s IMAX presentation found on the personal spleen site. That project took the 2.39 scenes presented in a 1920 by 1080 video, and cut to the 1.43 scenes from the Ultimate Collector’s Edition Bonus Disc, preserving the original aspect ratio of these shots.

My intent with this project was to go a little further and authentically recreate the effect of watching a 1.43 IMAX showing of the film. The 2.39 widescreen is placed in the center of your view, but for the IMAX shots instead of shrinking the 1.43 down to fit your TV screen, the top and bottom now expand to reveal much more picture, immersing you in the film as originally intended. I’ve found this method looks neat when outputting my laptop to a projector with a square aspect ratio and playing the video through something like VLC. It worked even better when streamed over Plex to my PS4, watching on my PlayStation VR headset and setting my “VR Screen Size” to Large. I wasn’t lucky enough to catch any of these movies in a 1.43 IMAX showing before COVID shut everything down, so this is my at-home remedy for that missed experience.

On the Blu-Ray, the 2.39 scenes end up taking up 1920 pixels wide and 960 pixels height of the 1920 by 1080 video file. On the Ultimate Collector’s Edition Bonus Disc, the 1.43 scenes from the Bonus Disc end up using 1550 pixels wide and 1080 high. I’ve chosen the video dimensions for v1.0 of this project to be 1550 by 1080p, preserving the full resolution of the 1.43 scenes as encoded within the 1920 by 1080 file. This does mean the 2.39 scenes are slightly downscaled to fit within these parameters, as I believe when any dimensions start to exceed 1920 by 1080, the video file would not play properly off a standard Blu-Ray disc.

Unfortunately, there are a couple issues in this otherwise simple edit:

  1. Many shots filmed with IMAX cameras whose aspect ratios open up from 2.39 to 1.78 on the Main Movie Blu-Ray do NOT have 1.43 equivalents included on the Bonus Disc. For the aforementioned “The Dark Knight” fan project, this problem was worked around by upscaling the Full Screen DVD for these shots, since that preserves the 1.43 ratio but at a 480p resolution. “The Dark Knight Rises” only received a Wide Screen DVD release. These shots I left intact at 1.78 for convenience but I am also excusing it by saying that “1.78 is close enough to preserving the alternative 1.90 digital IMAX ratio”. I also haven’t felt that these instances diminish the intended effect.

  2. The shot of Batman walking into Bane’s trap and the gate slamming down behind him starts in 2.39 then changes to 1.43 for a few frames. The effect SHOULD be 2.39 then immediately adding more image on the top and bottom to 1.43 image. However, since the Bonus Disc takes the 1.43 shots and shrinks it down to take up 1550 pixels wide instead of 1920 wide, this 2.39 shot actually gets cropped on the sides to 1.43 in order to appear consistent with how the other 1.43 shots appear on this disc. This creates the only instance where the 1.43 shot on the Bonus Disc is cropping out more image than it is revealing. For the Main Movie disc, the shot simply opens up to 1.78 with no side cropping, so I am using the 1.78 ratio for those very few frames. The gifs below are the cropped “1.43” followed by opened 1.78 ratios, brightened so you can see the difference.

  3. There’s one shot of The Bat flying above a Tumbler where you can tell it should be a 1.43 shot (the bottom definitely shows more image), but the top has been cropped just above where the top of the Bat would be. Perhaps this is to hide any equipment that they just could not digitally remove? I’ve used this “almost 1.43” version from the Bonus Disc, since I think you would hardly notice when watching.

Version 1.0 is just a real quick edit, no color correction, no overlaying parts of the image together. Maybe in the future when I have time (and if I ever learn to convert HDR to SDR), I’ll mess around with upscaling the 1.43 and overlaying the 4K version on it, or outputting at different dimensions so the 2.39 shots aren’t downscaled.

Video Sources:
• The Dark Knight Rises – main film (2.39/1.78), disc 4 from The Dark Knight Trilogy: Special Edition Blu-Ray
• The Dark Knight Rises IMAX Sequences - select scenes (1.43), disc 6 from The Dark Knight Trilogy: Special Edition Blu-Ray
Audio:
• DTS-HD 5.1 – English audio track, disc 4 from The Dark Knight Trilogy: Special Edition Blu-Ray

My current method for encoding is to make MP4 Passthrough videos from the Blu-ray discs, import into Adobe Premiere Pro, and then clicking “Match Sequence Settings” when I Export. Then, I use MKVtoolnixGUI to remux the Blu-Rays unaltered audio, chapters, and subs to this new video file. If you have any other suggestions on better lossless encoding and muxing (or if anyone happens to have the Cinema DTS audio mix), I would appreciate any help!

The Phantom Menace - Theatrical version scanned in 4K (a WIP)

Today is probably the good date to officialy announce that a scan in 4K, based on a 35mm in very good condition, is currently in progress.
And it will be done twice 😃

I received a few days ago from the lab in Paris a first test scan of reel 4 (made with a simple 720p scan), just to analyze the average condition of the reel before scanning it with a brand new 4K scanner. The lab scanned the entire reel… in 25 fps (the French standard) so it is not currently usable (there are ghosting artefacts and interpolated frames). Damn French people, always thinking that the world needs their own standards!

But It looks just gorgeous, even in 25 fps: the reel is in PERFECT condition, it looks like it was never projected before, the colors are perfectly preserved. The lab made NO correction at all (white balance, DNR or something else) and the rough result is astonishingly good.

The 4K scan will be obviously done in 24 fps, can’t wait to get it 😊

Happy birthday to TPM!

Any news about this 4K release ???

Eagerly awaiting news of this!

A 35mm scan is in the works at the moment. I believe ZigZig would be the person to get in touch with about that.

The scanning process is currently locked down in a Parisian lab due to Covid-19…
But I’d be happy to share with emanswfan the rough scan of reel #4 (which was done 2 times with 2 different lenses).

Emanswfan, if you’re interested, please feel free to PM me.

I’d love a copy too actually.

Me three

me four!

Recreating the TV Edits of the 2003 Clone Wars Series (HD) (Released)

I captured these when they originally aired using a Sony Digital-8 camcorder and transferred them via the Firewire to my PC… I believe D8 is 720x480. Not sure if I still have the original transfers, but I think I put them on DVD as individual episodes and my own version of a single movie. Useful for reference?

This is super helpful if you can get this uploaded!

Are you sure? I thought we had cinema DTS tracks for the 97 SE’s and the PT. I know we have TPM and ROTS, I was pretty positive we had AOTC, too.

You’re right, I just checked the usual place and we do have the PT DTS tracks.

That’s my bad, I’ve been out of the loop for a little bit.

Are they on the spleen, I couldn’t find them. Under what name?

I’d love a link to these as well, if they aren’t on the Spleen

Attack of the Clones 35mm - on eBay, bought - and now project thread (a WIP)

I got over the damn prequel poisoning, but then moved house to another city (which was a big move) and had some family crises that put everything else on hold for a while. I’ve only just started setting up my workstations etc again, and hope to have more time available for this in the coming months.

Clones is awaiting scanning, there are a few other movies in the queue, and I’ll need to get HDDs to store the scan (around 20TB for a scan of Clones), but it is on the list, and if there is interest here, it will get done.

Glad to hear you’re doing better!! The interest is certainly strong here, but your family and health comes first. 😃
