Should we? If the mods here agree, it could be done... I think... (^^,)

Wow, that's great!

About file hosting: mega.co.nz gives you 50GB free, and files *should* stay there as long as you wish, so...

So we can do an Extended Extended Cut! (^^,)

New users must post first in the presentation forum, but I made you Project Maker there right now, so now you must be free to visit any forum/threads!

As I wrote in the first post: "Notes: you need to sign up to see the first post with links." - just sign up, it's free, so you can read the post (and links); plus, I'll make you power user immediately!

Jedit: as per OT rules, I can't post direct download links...

Some server problems, probably... try now!

Your upscale script works very well - also thanks to the fact you use two sources; the comparisons with each sources speak for themselves!

The new script is not that different from the old one (which was good!) but if you look close, yes, the difference is there, not that great, but the new one improves a bit the very good result of the old script!

Sources: Russian DCP, English 1080p

You could find the link on fanres - note: you need to sign up AND BE Power User to see them... so, sign up, and then long time OT members should PM me to be promoted Power Users; newer ones should PM me for the links! (^^,) -> fanres PM: spoRv

Enjoy!

WOW! 56 seconds more... maybe someone could think they are not a great loss if they aren't in the BD, but I think, at the contrary, it's a GREAT discover!!!

Colors: it *seems* the film has too yellow, while the BD has too little yellow... (^^,)

That's a PaNup really enhanced script... good job!!!

I'd prefer a 90% close-to-DVD regrading than perfect color grading with 10% image cropped away...

I'd love to see this ported in Avisynth! Just the artefact grain reducing found in the PDF will improve ColurLike a lot!

Go for it, AntcuFaalb, go for it! (^^,)

I think it will be REALLY hard to align them spatially... but, *in theory* it could work, even if TB quality is quite low in comparison... further tests are needed...

The fact is, it's quite difficult to align spatially a DVD and BD, because 99% of the times crop is different, often from scene to scene or from shot to shot... what if, for example, you have the DVD covering just 90% of the BD image area? You'll leave four borders with BD color?

I must admit I haven't tried myself with this very title, but I'm almost sure it is like I suspect, or the project probably emerged some time ago... said that, it's still possible to color grading the EE BD using EE DVD as reference, but results may vary...

Even using PaNup with PAL and NTSC VHS, quality will be lower than any laserdisc; TB quality is good, but this time laserdisc is better - TPM is one of the best looking non-anamorphic laserdiscs ever made!

I noted the laserdisc is way better than TB...

Curious to know something more about this "patented haroldnipps method"...

hairy_hen, thanks for the explanation, you are always really helpful.

I would like to know what do you think of non-Dolby matrix surround "extraction" (process, decoding) techniques, like Shure Acra Vector, Fosgate 6-axis and so on...

Reading here and there, it seems they are very good, even better than Dolby Pro Logic, apart DTS Neo 6 and CircleSurround, which are not so good - or plainly "wrong"...

Thanks! Link is in the first post.

Even if it has not the "correct" placement, you could always do a listening test... what I need is not (only) the channel placements, but overall quality - e.g. if one (or more) of the encoded ac3 files sounds "right" - equal or better than the stereo wav.

I'd like to get some feedbacks on the difference between the stereo track, listened with a Dolby Pro Logic hardware decoder, and the other encoded tracks, obtained in different manners - 4 are upmixed using Foobar2000 and different plugins, 1 is captured from L, C, R, S outputs of a Pro Logic decoder, then surround is "steroized" using Audacity Pseudo-Stereo plugin, then an LFE is obtained with a low pass of the previous 5 channels, where those are then high passed.

So, a listening test with your setup will be greatly appreciated!

Back to Womble: AFAIK, no software could exactly decode (better, process) a Dolby Surround encoded stereo track, at least not so well as hardware decoder, in particular vintage ones, but this will lead to an entirely new discussion... (^^,) - that I will be happy to partecipate, but with not enough knowledge to start!

EDIT: ...but if you would like to do a conversion using Wooble and the original stereo track, I'm curious to see if the result is similar to the one I reached using hardware!

I'm working on an hardware decoder capture solution about Dolby Surround encoded stereo tracks; I need someone who owns a Dolby Pro Logic compatible amplifiers that would help testing few files; they are the untouched stereo DS encoded track, plus five different surround recreation files - between them, there is my solution.

So, what I need is a comparative test between the original track, decoded by your hardware Dolby Pro Logic (not II) and the others (endoded in Dolby Digital); at the end, I would like to know which (if any) is the most similar to, or even better than, the DPL decoded track.

Original track is from analog laserdisc, and includes DTS and THX logo - 44s

Tracks included: original.wav, 1.ac3, 2.ac3, 3.ac3, 4.ac3, 5.ac3 - avoided to name them after the surround plugin used, to have a blind test.

Thanks in advance for your help!

...so it seems you have updated the project from 720p to 1080p... good choice!!!

I don't know what the laserdisc colours look like, can you post some screencaps Andrea?

...too tired to search between thousand discs to find it, and then capture it... (^^,) I spent the whole day with the hardware pro-logic test...

Maybe it could also be taken in consideration the option of using the laserdisc as reference to color correct the DCP...
