Harmy's STAR WARS Despecialized Edition HD - V2.7 - MKV (Released)
Time

The red drives report any read or write errors back to the controller very quickly instead of stalling and going into the recovery mode where the drive automatically tries to remap the sector by reading over and over.  If you only have one disk, then this is the only chance to get your data from that sector back and, if successful, I don't believe the error is ever reported to the controller (but it should be visible in the SMART data).

In a multi-disk array this interruption will cause the array to degrade due to the lengthy timeout and the disk will be marked bad.  This is undesirable for an array since it has redundancy built in above the physical disk layer.

When an array of red drives detects the error, the sector is marked as bad immediately, the sector is remapped and the data is recovered using the parity stored in the array itself (RAID 5 for example).  This saves having to recover an entire degraded array due to one error (of which there can be many before the disk is truly bad).

Other than that, I'm not sure what the other differences between the drives are, but I believe this is the biggest one.  So the extra cost is probably unnecessary.

Why MPEG2 is not as bad as you may think...
Time

As you can see, images are really close in quality, right? But, according to PSNR, the first has only 3/4th quality of the second, while using only our eyes, we should disagree, as we think quality is really close...

I don't know...  When I first looked at these two images (without reading any of the text), the second one definitely looked off.  Inspecting closer the quality was certainly worse by an obvious amount (at least to my eyes).

I don't really know much about PSNR vs. SSIM, but I would venture a guess that if these images were in motion, it would be much more difficult to tell the difference between the two compression levels?

The Hobbit (2014) - Resource and idea thread
Time

Sounds great!  I have a couple of comments.

I wouldn't necessarily limit yourself to 200 minutes, it just seems arbitrary.  Better to have great scene flow and nice clean edits and let the time fall where it may.  In other words, don't cut something purely for time reasons, cut it because it doesn't belong, or because is doesn't fit properly.

My one suggestion for DoS is to try and get rid of the fact that they basically reveal exactly how the dragon is going to be killed very early on.  My recollection from the book was that there was much more tension about this point and it doesn't all come together until Smaug is attacking Laketown.  I could be remembering wrong though... it's been a while.  Basically, when I was watching the movie, I felt that Smaug didn't really pose a threat since we knew who was going to kill him, where and with exactly what weapon.

Restoration tips: Slice Technique™
Time

_,,,^..^,,,_ said:

see the missing piece at the bottom right? Unless there is some method to "invent" the missing piece using surrounding images... and I'm afraid, there is not (yet)!

Photoshop has a function that replaces a section of an image with estimated data from the region around it.  I'm not sure if there is an open source implementation of this out there, but I believe you could get decent automated results in this case since you are operating in the very corner of every frame.

A similar technique could also be used to aid with logo removal, but more noticeable artifacts would probably occur when compared to the above example since the logo can intrude quite far into the frame.

The Hobbit (2014) - Resource and idea thread

Even before the first of this three-film disaster was released, I knew that the only way to undo the damage would be to massively re-edit them all down into one film, cutting out everything that isn't actually in the book and restoring a proper pace and momentum to the story.

As it stands, the whole thing is just an exercise in how to pad something out for length far beyond the point where it even makes sense anymore, as well as a blatant money-making grab by the studio.  I consider it a shameful mistreatment of Tolkien's story.

Since there is some good stuff in there, nearly buried under the weight of Jackson's foolishness but nonetheless apparent, pruning it down to the essentials would certainly result in one film's worth of watchable material.  I'm glad to see I'm not the only one who had this idea, and once all the movies have been released I'd love to see a project like this happen.

I do have to admit that Benedict Cumberbatch as the dragon's voice is an inspired choice.  ;)

 ^ This!  We should all be thankful Jackson did in fact make three films.  All the more material to pull from for a Hobbit book version.

If anyone else had made the movie and it wasn't up to par, we would just be stuck with that.  This gives me great hope.

Info Wanted: 'LOTR - FELLOWSHIP OF THE RING': Green tint removed?
Time

You_Too said:

I know kk650 showed that there was a green tint even in The Hobbit.

I checked it out and he was right, all the way from the MGM logo until the credits start there is a green tint. Even the hardcoded english subs aren't white!

This made me interested in seeing whether or not the theatrical trailer looked like that. Here's the same shot (different takes though, obviously) taken from the trailer vs the blu-ray.

Seems Peter Jackson has started to love cyan skies and green clouds.

The bottom one looks like a badly done HDR image to me.  The shadows look way over-brightened.  Is this really what the blu-rays look like?

OK, if someone can tell me how to save images from that eBay auction, I'll post them up here.

I seem to be able to right-click and Save As all images on eBay in the current Firefox. A month or two back I had to resort to tricks like Inspect Element or searching the source for the JPG URLs... so try that.

There are browser addons that enable this functionality.  I'm currently using one called "ebay - item description - save enlarged pix" for Firefox, but there are probably others out there.

The main thing I like about this one is that it enables drag and drop saving which is much faster for me.

It would kinda suck if Disney took this away from Harmy to release officially but even though it is official and all it is Harmy's work so they would have to get his permission to do that.

Does anyone believe that Disney would do a better or more complete job than what was accomplished here?  Sorry, but I don't see it no matter who is or isn't involved with this franchise at this point.

I will grant that they probably have access to more resources, better source media and all that, but look at all the garbage HD releases out there that claim to be the cats pajamas.  Far too many if you ask me.

More thanks that I have go to Harmy for saving this piece of cinematic history.

I'm definitely still interested in making a documentary of sorts about the various audio tracks; it's simply a matter of finding the time to actually do it.  There's a lot to talk about, and I would certainly try to present as much information as possible (both about the tracks themselves and what was done to optimize them), but without going into so much obscure detail that it would confuse people.

Hey, some of us like obscure details!  You could always make an extras feature for the extras :D

Robocop - Director's Cut 1080p restoration (Released)

I don't want added grain. *sigh* That's just added noise because it isn't real.

We need a proper Blu-Ray. If they screw that one up, well then we have to do what we can. 

bigrob, I hope that's true and that next year we will see just such a release.

Personally, I would disagree with the first statement (just my opinion).  If I have a choice between two clips, one DNR'd to hell and the other with suitable grain added back in, I will always choose the later.

There was a document floating around here a while ago taking about the effects of grain on the perceived image which was really interesting.

I also totally agree that there needs to be a proper release of this movie.  I'm watching the Criterion DVD right now as a matter of fact :D  A nice coincidence!
