@althor1138

The 480p stream is definitely problematic.  You encoded it with a soft pulldown, which is understandable for BD, but unnecessary for an MKV release.  (I'm sorry.  I should have made that clearer.)  Moreover, the framerate and DAR of the bitstream don't match those of the container.  When I tried to strip the pulldown, I found that the video had gaps.

If you show me the script that you used and the encoding settings, I can try to help.  This, rather than a problem with your IVTC, is probably why people are seeing combing.

By far, your 480p stream is the best "pure" transfer of the JSC Star Wars I've ever had access to.

I couldn't agree more.

Althor1138, this looks very, very good. Great work!  It's fantastic having 720p and 480p versions.  An MKV version really was the way to go.  Many thanks for doing this!

althor1138 said:  What is the consensus on the denoising used on the 720p stream?  I'm open to suggestions to make it better.

It looks fine to me, but I'm easier to please than most folks when it comes to denoising.  What did you use, by the way?

Thank you to the usenet uploader as well.

FFMPEGSource2 is good only for progressive AVC.  Was your source interlaced?  Putting Assumefps(24000,1001) after FFMS2() in your script can help correct the framerate, but I doubt it helps with dupe frames.  (I've never had it give me dupes though.)

EDIT:  I assume you demuxed to MKV first.  FFMS2() has problems with elementary streams.  This is what I do.

LoadPlugin("C:\Program Files (x86)\Haali\MatroskaSplitter\avss.dll")

FFMS2()

DGAVCDec is no longer supported, but its author is still actively working on DGIndexNV, which I highly recommend.  If you don't have an NVIDIA card, you might look at DGAVCDecDI if you haven't tried it already.

DoomBot said:Must be what Chewtobacca was talking about with the YUV?

No.   I was talking about the fact that it's not necessary to convert the Blu-ray from YUV to RGB and back for the sake of adding a few frames.

A slight color change might be a result of encoding with Rec.601 rather than Rec.709 coefficients, which are required for HD, but I don't use the program you're using, nor would I, so I can't give you any advice about it.

Info: Films re-color timed on video releases
Time

Are you compiling a list or is this thread just for general discussion?

captainsolo said: And yes, I still think Raiders looks off somehow. But that may be just me. ;)

No one's going to convince me that Raiders looked like the BD originally, but we've all been over that one before. :-)

I share your frustration.  Color is the most important aspect of any release for me more important than the presence or absence of DNR, EE, grain, noise, and so on, and far more important than resolution.  That said, revisionist color timing is absolutely fine by me, as long as the original is released too.

I'd say so.

While I am interested in your release, I have no desire to watch a non-anamorphic video with Japanese subtitles.  If you did go down that route, I would have to recompress it before I watched it.  If your concern is that the JSC should be preserved "as is", be aware that it has already been done: one of dark_jedi's early releases had the Japanese subtitles.

CapableMetal said:I think that both AVCHD and Blu-Ray specs only allow for interlaced content at SD resolutions.

Pulldown and the fake-interlaced switch can be used to encode 480p for BD.

The raw capture ends up being around 24gb when compressed to lagarith.  The x264  or mpeg2 encode ends up being around 21-22 gb so it's basically like having a raw capture of the laserdisc that can be popped into the blu-ray player.

I understand that you want to preserve quality, but the numbers are confusing you a bit, I think.  Just because the lossless AVI is 24GB doesn't mean that you need a similar size after encoding to a delivery format to have something that looks like a raw capture on the disc.  After your current encoding is finished, try using a CRF of 16 (which is absolutely sufficient to make something look like the source) and let us know the file-size.  I bet it will be something like 3GB.

I won't be resizing or cropping if at all possible.

Wait, so you're leaving it 4:3?  I'd strongly advise you to make it 16:9 anamorphic.  It won't really hurt the picture, and it will be far nicer for people to play it back without zooming in.
