Deep Space Nine Upscale Project Update: ‘Sacrifice of Angels’

It’s been pretty much particularly a thirty day period because I posted my very last Deep Place 9 report, the place I showed how various AI computer software could upscale the display to a thing approaching High definition good quality. Even with the ongoing pandemic, I’ve held the Cascade Lake testbed and RTX 2080 crunching busily away, testing different permutations. Some folks have contacted me to categorical curiosity in doing work jointly, and I’ve discovered some appealing matters together the way.

I have not been capable to come across my DVDs, so I acquired Year 6 brand name-new and began doing work with that resource. I chose Year 6 because it has some of the greatest room-battle scenes, which include the major struggle ever staged in the Star Trek universe in the episode “Sacrifice of Angels.” SoA was the clear episode to operate with and the Defiant image earlier mentioned is from an upscaled encode. Here’s the whole shot.

I experienced hoped that the DVD resource would present a better upscaling option than working with presently-encoded MKVs. I still consider it does, but men, I have to tell you — the baseline DS9 resource sucks.

I watched this display when it was broadcast on cable, on a new 24-inch Television my mother and father experienced just acquired. It’s just one of my all-time favored displays, and viewing it on DVD appears to be nothing at all like viewing it on Television did 25 a long time in the past. Of course the base resolution is lower, but that’s not the difficulty. The video is noisy, it is considerably darker than I don’t forget, there’s a evidently obvious 3:2 pulldown/telecine result, and distant vessels are frequently greatly aliased (meaning they crawl with jagged lines). The credits are specially negative as significantly as image good quality. If the rest of the display looked as negative as the credits, I’d never want to view it. I may perhaps upload a number of video clips just to display how tough they are.

This is what 3:2 pulldown appears to be like. You are practically observing 50 % a frame of details, which is why every single other line is blank. There are a range of these times in any supplied episode, and though they really don’t avoid everyone from making the most of the display, they can be irritating.


Nana Visitor’s reaction to the DVD resource quality… or a extremely blessed pause on my portion. You be the decide.

What I’ve Been Functioning On (and Realized)

Here’s the trustworthy reality: You can get a really great on the lookout video if you just rip the DVD with out deinterlacing or detelecine by using Handbrake (use the H.264 Creation Max preset) and then upscale it. While the 50 %-frame transitions are recognizable and irritating, upscaling this way actually cleans up some places that are or else fairly jagged and “crawly” at specific factors in the display. If you want a just one-and-carried out remedy and you are not bothered by the occasional 50 %-frame, it is a good solution and I advise it. The outcome is 70-80 percent of what I imagine is likely possible, greatest-situation. If you rip the DVD working with Handbrake’s detelecine solution, it will resolve the 50 %-frame flicker, but at the cost of introducing extra aliasing that wasn’t existing ahead of. In my viewpoint, the telecined upscaled DVD appears to be better, on the entire, than the detelecined Handbrake output article-upscale.

My very long-term target with this undertaking is to build a information working with as considerably totally free computer software as is possible (Topaz VEAI is certainly a paid obtain). I’m doing work with a reader who has carried out some remarkable coloration stability improvements, and I’m thrilled about what that may possibly signify for the undertaking.

What I’ve carried out for the earlier thirty day period? About 600GB of renders at 3-8GB each individual. I’ve been examining coloration grading with DaVinci Solve, rescaling in that same application, different AviSynth filters for antialiasing, detelecine, and deinterlacing working with algorithms like QTGMC. The reality is, I could speed up the method if I concentrated on lesser clips, but I favor to upscale the overall episode. That way, I can check any difficulty place or difficulty location in just one location of an encode versus all the prior configurations I’ve tested, to see how that individual location was dealt with.

A further detail I’ve discovered? The greatest version of Deep Place 9 would be made clip by clip, working with optimized video processing configurations for each individual. I have no intention of slicing and dicing episodes up by hand, but if there was an episode you definitely liked, you could reach some definitely extraordinary outcomes that way.

I want to display you a short clip from “Sacrifice of Angels.” Initially, the DVD resource and 2nd, the upscaled output with QTGMC utilized. QTGMC is a deinterlacing filter, not a detelecine filter, and it is effective by creating extra frames. The final output does not have the hypersmooth search of interpolated sporting activities video, but I’ve experienced difficulty matching audio to the clip. There’s a whole lot of hands-on discovering associated in this sort of undertaking because ultimately, each individual video rewards from a various established of filters. For greatest good quality, transform both video clips to major accessible playback resource.

This is the unique DVD resource. Take note how the nacelles on the Miranda-class starship (the two ships in the opening frames) shimmer. This is telecined output, which means they search considerably better in this video than they do if I detelecine the resource working with Handbrake. There’s a whole lot of sounds in specific frames and some obvious compression artifacts in other individuals.

This is the upscaled video following I utilized QTGMC deinterlacing to it by using a buggy and challenging-to-parse application named StaxRip. It’s been amazingly beneficial to me in specific respects, but if I’m getting trustworthy, I’m attempting to come across an option because this app is alternatively ornery and challenging to use. It also only appears to be to output H.265. Figuring out how to use programs like AviSynth (present user level: Lousy) is portion of the encounter. A person of our viewers, Shortstick, has contacted me to display off some of his have coloration grading operate on DS9, with extraordinary outcomes:

We are on the lookout into how to incorporate efforts and even more make improvements to the display.

Why I’m Performing This

If you watched Deep Place 9 on Television escalating up as I did, I have news for you: You never actually noticed the operate that VFX designers place into all those struggle scenes. Watching “Sacrifice of Angels” in upscale on a considerably bigger display screen, I was struck by how remarkable the shots were being. The room struggle in Insurrection may perhaps have experienced more highly-priced unique consequences and a number of more a long time of CGI improvements, but it didn’t require 50 % as quite a few ships or as quite a few advanced maneuvers.

Until finally I began doing work on this episode, I never assumed about how room battle evolved from Star Trek: The Future Generation to DS9. On TNG, struggle is pretty much stately, with significant ships firing at each individual other from static positions. The exception to this is stern chases, the place the Organization is pursued by an opponent.

DS9 changed all that. The choice to introduce the Defiant and to make it a compact ship wholly changed the rhythm and flow of room battle. The Defiant wasn’t made for stately, sweeping broadsides — it is an antimatter-driven traveling gun that can absorb important quantities of hurt though it blows your ass into future week. Higher than all, the Defiant is quick, and Jadzia Dax is just one hell of a pilot.

The overall struggle “language” of Star Trek changed substantially amongst TNG and DS9, mostly on the backs of the VFX artists who were being tasked with executing the operate. DS9 didn’t just incorporate more ships it showed all those ships executing more matters, with track record battles frequently as extraordinary as the foreground shots. Correct, some folks disliked the search and favored the plan of a more unfold-out fleet engagement, but I’m not just one of them. I’m viewing a display in which aliens with no principle of time dwell inside a secure wormhole. I really don’t will need the starships to keep significantly away from each individual other to appreciate the struggle scenes.

Talking of wormholes…

Watching this episode in standard DVD good quality is like on the lookout at a da Vinci portray with 500 a long time of grime on it. You can recognize the mastery of the operate, but there’s a whole lot of schmutz amongst you and it. Many thanks to improvements in AI processing, we’re at last observing consumer equipment that can wipe the grime away — and not just for DS9, but for any range of extra displays. The artists that worked on these episodes have earned to have their operate viewed in a thing approaching the way it could have looked.

I’m never likely to be capable to make these aged DVDs search as great as what Paramount could do. Heck, I’m never likely to make improvements to them as considerably as a expert video editor could do. But Paramount has no plans to upgrade DS9 by itself, and that means the only way to restore the Television display to some semblance of how it could search is with a whole lot of elbow grease, filter testing, and just one exhausted RTX 2080. I imagine the operate justifies to be carried out, even if Paramount disagrees.
