Fantasia's 'Fantasound' Manual Recreation (WIP)
Time

You might be confusing playback with recording tracks.

The 7 tracks were used for studio recording only, and then mixed down to 3 on the actual movie.
So you have 3 tracks + control (http://www.widescreenmuseum.com/sound/fantasound1.htm)
“four photocells which scan three program tracks and a pilot control-track”

The control track was there to extend the dynamic range of the audio tracks. Basically it did volume/noise control.
The manual panning was done on top of that, directing each of the 3 audio tracks towards specific speaker(s).

The 3 program tracks are not LRC, they can be any arbitrary channel combination. For example Ls, C, R or Ls, Rs, R

From reading http://www.widescreenmuseum.com/sound/fantasound1.htm I think there where 3 independent sound channels.
Each channel was directed towards a speaker (L C R Ls Rs) according to a control track. Basically they did the mix on playback.

The 3 original channels don’t correspond to any specific speakers. Channel 1 could be directed to L at one point, and later on to R. So you absolutely need the control track to recreate it.

In theory Dolby Surround can reproduce the original mix perfectly.
Modern signal processing gives you quite good separation, even with complex sounds.

'Privateer 2 - The Darkening' upscaled sequences... (Released)
Time

I managed to incorporate those scenes into a full edit, based on a YouTube video of the entire “game movie”.
It’s not bad, but it becomes boring after a few minutes, since you only follow a single character.

As for quality .tgv are the best source. I remastered the VHS footage to match them regarding color and brightness and it looks decent (for what it is).

Anyway, sending you a link to the full edit, check you PMs.

Maybe one or two shots, if any at all, may be used

If you restore the original space battle sequence the extra guys in the Falcon make sense. They do disappear out of the cockpit in the theatrical cut, and Lando gives orders/reacts to repairs being done by someone else on the Falcon 😉

Here’s the second space battle sequence with the extra crew as a proof of concept:

I mentioned this earlier but the scenes between Han and Leia need to be more intimate.

Quick, someone find out if Carrie Fisher has ever done a sex scene in her career! 😉

You don’t need that. Cutting out the love triangle with Luke is a first step.

I know, I was joking. It’s a reference to some of the conversation that was going on in the prequel redux thread recently. Someone was trying to add a sex scene between Anakin and Padme, using footage from another Natalie Portman movie.

That scene works well in the context of Episode III. But on Jedi no.

Star Trek Deep Space Nine - NTSC DVD Restoration &amp; 1080p HD Enhancement (Emissary Released)
Time

Early 1990s NTSC video was generally mastered to different monitors than we have today. So you need to adjust gamma, saturation and hue. In fact the colorspace might even be slightly different, but I don’t think there’s any software to handle that.

So your best bet is to adjust “by hand”. You can use the TNG remasters are reference, since uniforms and some sets will be similar.
Or you can take a look here: http://blog.trekcore.com/2019/05/exclusive-star-trek-deep-space-nine-hd-what-we-left-behind-footage/

On my tests I used something like gamma 1.4; saturation 130% and a -4% hue shift. Also clipped black a bit on levels.

Star Trek Deep Space Nine - NTSC DVD Restoration &amp; 1080p HD Enhancement (Emissary Released)
Time

I’ve analyzed the pilot’s DVD video structure and I have good and bad news.

The good news both the live action and effect shots are at 24 fps, encoded as 3:2 pulldown. So no separate processing is needed. (The initial crawl is at 30 fps but I think it can be disregarded)

The bad news is that the show was edited on video (60/30 fps), so scene changes don’t match 24fps.
That is, scene changes can occur at any frame, and break the 3:2 pulldown pattern.
So we get interlaced frames here and there, until the pulldown filter adapts. I’m using VirtualDub, but the same should apply to other software.
3:2 pulldown only: https://streamable.com/xg8qrs

One option is to run a deinterlacer over the 24fps material. You end up with some duplicate frames and deinterlace artifacts.
3:2 pulldown + deinterlace: https://streamable.com/4i214c

Another option is to simulate what an old CRT would do, and simply deinterlace everything and present it at 60fps. You get duplicate frames and some deinterlace artifacts, but it doesn’t look bad.
Deinterlace to 60p: https://streamable.com/wqrhbi

I decided to try a frame based upscaler on the first 2 versions.
On top you have the result at 960x720. On the bottom row I unsharpened to images to analyze detail.
As expected the 3:2 pulldown only version has better detail.
https://images2.imagebam.com/39/03/7e/a32a6c1349363260.png

So it’s a tricky situation…

PS - all DVD samples had level, gamma and saturation adjusted. I also run a chroma filter to get rid of line artifacts on some frames.

They look a little on the soft side (probably due to noise and grain reduction). Let’s wait and see.

The general softness can mean that they are free from edge enhancement.
But I agree that on gradients and low contrast areas there’s almost no detail. Compression is really hard here.
On the other hand DVDs usually have macroblocks on such areas…

I’m not sure if these will be a better source or not, but worth a look.

Looking at the JPGs these upscales might have less compression artifacts than the DVDs. In terms of visual detail, it’s in line with a good 640x480 master tape. Again, might be slightly better than the DVDs.

I too would like a sample of the unaltered capture. I just want to run some filters on VirtualDub. We have a tricky situation here with 60i » 24p / 30p content…
This will not interfere with Animaxx’s work, just experimenting other possible solutions.

This is an interesting project, but looking at your first 3 steps:

  1. Copy the original DVD-Stream (VOB-Files) from the NTSC-DVD (SD-Resolution at 720x480p in 4:3 at VFR between 23,976 and 29,970 FPS)
  2. Recode the episode to conform to a constant Framerate of 23,976 FPS
  3. Deinterlace the episode to go from interlaced to progressive

I spot some problems there. I strongly doubt there’s any variable frame rate on those DVDs *
What you should have is a standard NTSC 3:2 pull-down for the 24fps film segments, and standard 60fps video for the effect composites.

So your first step would be to get rid of the pull-down, and that would also remove any interlace artifacts on the film segments. You get 24fps non interlaced video.
The effect sequences require a separate treatment. There a normal deinterlace filter would do, coupled with frame rate conversion (60 » 24fps).

  • Your SD sample from the DVD is very strange. It’s a 60fps video with doubled frames. Did you run a deinterlacer on it ? There’s some residual interlaced frames when it switches to the battle scene (frame 2212).
    Can you share the original sequence in unchanged VOB/MP2 format ?

As you are doing, you are running a line doubling deinterlacer (step 3). I seem to see some deinterlace artifacts on your SD-Quality (NTSC DVD) link images. And why are those images in 768x576 ?

I not saying this to put you down, just to prevent you from spending more time with something that has problems from the start. PM me to further discuss this, perhaps I can help!

(of course I might be wrong, but from the images you posted I seem to stop these problems)

Not just on that scene.

Your added colors and effects are great!

But the untouched elements from the new masters just look grey and dull to me. It looks like gamma is off or something.
I wonder if they mastered this to something other than BT.709…

You improved it a bit but it’s still too dark in general.
It’s perfect on the Admiral Ackbar scene. So go for that look.
But it’s awful on the first Luke image. He’s brown over a gray background…

Enter the Dragon (a WIP)
Time

I played a bit with this movie and it can be improved by some scene reordering and trimming of Roper and Williams.
Basically:

  • Open with Roper and Williams flashbacks
  • Tighten pacing on Lee’s fight, abbot scene, recruitment.
  • Tighten boat sequence to get them all to the island quick.
  • Add deleted scenes to show Lee as a master (show his book)
  • On the island, tighten dinner scene around Lee
  • Only one night passes (condense all action to one night)
  • All tournament sequences happen the following morning/day, trim Roper and Williams fights.

Just putting this here because it works reasonably well and fits the existing footage.

I agree that ROTJ needs visual intensity. So anything done in that regard is good.
May I suggest adding some fog elements ?
There’s some decent green screen fog/dust footage that you could use for Endor. Perhaps alternate between sunlight and fog to show different places ?
As it is we get the impression that it was all filmed in the same small stretch of forest…

Not sure Added Lucrehulk, Hammerhead and U-wing to a couple of shots during the battle. They are from YouTube’s green screen, so I’ll keep them if they are at least bearable.

In the background and slightly blurred the should look fine. Try the fan film “Battle of the Dreadnoughts” for some extra battle footage…

Not sure Added a couple of shots from deleted scenes (probably the rebels firing from the Falcon’s turrets).

Yes, because those guys are seen behind Lando and then disappear. And if I’m not mistaken one of the dudes is seen on TROS firing the turret 😉

(I’d also recommend you add some of the bunker action, to make up for the trimmed Ewok action)
