Thanks for the support, and for the clip!

These situations always unsettle and sadden me a bit because, even just from a philosophical and philological point of view, it is bad that so much (gay) porn content keeps being "lost" - or at least forgotten.

This seems to be more true for legacy media, which is a shame because e.g. the scene I am looking for had a captivating voyeuristic feel to it and really cool ambient music, too. Truly in stark contrast to todays super-polished fetish video content...

Hi All,

so I remember at some point downloading this old (as in, the video was likely originally shot on VHS) fetish scene that consists mostly of sounding. One guy is dressed in scrubs and process to use a number of different tools on his cock head and urethra.

I know for sure I downloaded this torrent, but due to changing drive I have lost the footage, and now I think the torrent itself has been deleted from GTRU.

Is there any way I can recover at least a list of all the torrents I have downloaded, including possibly deleted ones? Alternatively, can anyone help ID the specific video I am mentioning?

Sorry for posing such a broad question, but I really thought the video was neat!

uTorrent and likely these other apps too are all 32bit applications, for which macOS Catalina removed support.

To put in simply, Mac apps (but really, virtually all modern computer applications) usually come in 2 "flavours": 32bit or the more modern 64bit. The difference is pretty technical, but in practice this means the at the OS level, 32bit Mac apps are not at all compatible with Catalina - they simply will not run.

Seeing how macOS is closed course, the problem will likely not be solvable by users anytime soon…

Bet advice I can give: for torrents, switch to Transmission, and for Zip/Rar extraction use The Unarchiver

@gouryuu:

Upscaling a SD video and adding frames to make it 60 fps interpolated, (sorry is someone feels ofended) that's bullshit.

It has no sense, you won't get better quality by doing that, you will just get a bigger file size.

The reason why there are old films restored to HD/4K versions and they look really good, it's because those films (of big studios, with big budget generally) were recorded in 35mm, 65mm and 70mm films stock, the way image was saved in those films stock was completally different from actual digital cameras.

But if you don't have those original films stocks, you won't get better quality from an DVD image.

The best you can do, as eobox91103 says, is to let televisions use their own system to adjust the image, if the video you're playing has good quality (for example a well encoded SD video from a DVD source) it will look better than those upscaled videos, even if it's not HD.

(Hey AOS, good to see you here too)

I don't see how much the discussion relates to film restoration and digital film stock scanning… I agree and it is true that upscaling high-quality SD content and adding interpolation frames to make it "high-frame rate" is definitely not going to make a meaningful difference, but will likely just make the picture more muddy and janky.

However, this needs not be completely true for all types of old, lossy-encoded digital content.

Just think about all the MPEG2 encoded videos that were then re-encoded in mid-quality h264/AVC - in these cases, there often is a significant degradation in quality due to encoding artefacts (blocky frames, smeared uniform colour areas, uneven gradients and so forth), chroma subsampling and interlaced-to-progressive adaptation. Newer, smarter super-resolution algorithms are known to perform really good in ironing out these artefacts and in proving a much better perceptual quality - and one certainly does not need to go from 480p to 4K at all. In fact, some algorithms work like a charm even when targeting the same resolution of the input for the output!

And yes, in the process we add some pixels that where not there before… yet that happens anyway when you watch a DVD on an HD television, just you don't know how it is done. I think it is better when the users have control over how upscaling/super-resolution is done.

Once it is done, we can still re-encode it in h264/h265/AV1 and have a small file with nicer visual quality than before. Doesn't sound so bad to me!

Hi there was someone who uploaded videos like this torrent
https://www.gaytorrent.ru/details.php?id=c1c9a8207cbc1ef06ca7cba6aabba0fef7ed87e9409ab563

where they upscaled dvd to this blu ray ish hq format. I was wondering if anyone knew who the uploader was or knew their process to achieve this. They left a snippet of what they did but without instructions.
"Yes, All the "upscaled from DVD" videos are converted from original DVD.
This is how I do:

1. Deinterlacing
Avisynth script QTGMC

2.Upscaling
VirtualDub External filter SUPER RESOLUTION and internal filter WARP SHARP

3.Interpolationg
After Effects external plugin TWIXTOR "

Honestly, I don't believe in those things. There is very little improvement that can be made from an "upscaled" DVD. Same is true when someone thinks that can take an audio recording from MONO and make it HD. All you're really doing is just making it stereo! The only thing other you can probably do is adjust the equalizer to make the sound more pleasing. But it's still an analog recording.

The only reason why people do this is their crazy beliefs, or they just want a larger file to bet a bigger ratio return.

The biggest issue at play here is - more generally - most "off the shelf" algorithms for video upscaling ( i..e DVD to HD, for example ), are really not very sophisticated and most of the time actually worsen the overall perception of quality of a video.

The best consumer available stuff that does upscaling/super-resolution quite well is mostly found in high-end TVs (Sony is really good at this, for example). But then again, that stuff if proprietary so you can't really use it on your computer anyway…

If you really really really want to upscale something well, the you might as well look at more modern "deep learning" super-resolution approaches. There are now a lot of them, and the quality keeps steadily improving: https://github.com/ChaofWang/Awesome-Super-Resolution, https://github.com/thangvubk/video-super-resolution.

However, deep-learning super-resolution - while really much better than anything else - is extremely expensive, complex and taxing to implement: this stuff usually runs on what a normal person can already consider a "supercomputer" ($15k computer equipment, most of the time). If you are a prosumer gamer type, then you might be able to upscale a few videos and get cool results, but for the average joe, this approach is simply impractically (and probably, shall I say, unnecessary).
