Qtgmc Hybrid

[Claude]

HI
Im trying to deinterlace a DVD lossy using QTGMC hybrid.
Could someone explain what are the best settings.
Im trying to preserve as much quality as possible.
I hope to upscale it and transfer to blu-ray
Is the quality better from doubled framerate or not?
Any help would be greatly appreciated.

I think @ForSerious found that those settings (posted below) are best for him, you might also want to give it a shot.
I am still testing his settings prior to upscaling compared to mines to see who generates the best quality at the end of the upscale for my use cases.

A little stress workflow test with a mix of hybrid and Karl's 4k to FHD script conversions.
BTW I asked Selur - with @Karl 's permission and approval, thanks man! - if he would consider implementing Karl's script. He's probably thinking about it or writing poetry for his beloved one, you never know ,-)

A - The couple examples above are lanczos upscale (hybrid) + karl's downscale. Why I did like this? Just look at the freaking GH3 skin tones and noise pattern/gradients. So I guess that wouldn't be too stupid on my part assuming that (workflow's resulting proRES4444444) would grade better; at least how I grade, basically with a a torch and a hammer :P

B - Then for web content; the x265 codec is - well we all heard h265 HEVC praisings which is in what is based - very good. AFAIK only vimeo's bacteria are digesting x265 stuff, nevertheless any player based in ffmpeg can play it, movist, vlc, mplayerX, etc.

A much simplier free video conversion tool for internet zombies, lazy folks or children with no friends is Adapter. Settings interface vaguely reminds of Episode. It is also very fast, it has x264 but... well just look at the radioactive creature / icon ja ja ja, WTF is that??!!!... never mind is chooo kkiiiuuttt :D

Yo @karl wise ass tweaking wizard :P
from your link: Axolotls are used extensively in scientific research due to their ability to regenerate limbs. Axolotls were also sold as food in Mexican markets and were a staple in the Aztec diet.

Now that I think about it, maybe it's not a bad idea if Selur also prospects for some weird endangered species to iconise his fab little hybrid. Somekind of exoesqueleton soft inside creature with many ramificating arms, both sexes, stereoscopic vision, plenty of midiclorinos and chromatophores, ultrasound and 5600 K light emitting capabilities, mind reading and wormhole fart abilities and a diet consisting of just radioactive algae and politician's toes.

BTW in the last test version of hybrid I'm trying, Selur has fixed the QT recognition of proRES444 =)
And yet another nice thing that I found to be a big PITA in ffmpeg and does not happen in hybrid is to get stuck when the file has data stream aka spok's timecode

Here's a quick and dirty run through:
Before anything, one of hybrid's hyper-helpful features is little cute stickies which make quite easy to understand what the fuck are we doing... I learnt to use the app by myself which brought a bit of frustration at first, nothing major. But let's hit the crowd, shall we?

In the third tab we can do exactly what it reads, crop and resize. You can also change and distort PAR (pixel aspect ratios). If cropping, theres a nice preview button down right. About resize, when I use it, I check the auto option to mod 2 as it is easier to spot a wrong dialled value; bicubic spline for downscale, lanczos for upscale. There's still a misc sub-tab with several crop options and the force 444 downsize option (linked with at least x2 times downscale and karl script), I did wrote about in previous post.

Next, filters. Not all the filters work with all the encoders. With proRES, you can use the filtering sub-tab without problems. All filters work well but make encoding more lengthly. The denoiser it is very nice (and worth tweaking), when you start using it together with gradfun or dither... you won't ever want to use other thing. Last sub-tab of filtering is for tweaking speed. Dropping frames, changing speed read... the stickies explain it fairly well.

Next important stop, audio. You can use audio stream from file source or add a new one. Here you'll select audio format compatible with video format. In the filtering section you can change/add DRC (dynamic range compression), method used it and downmix it in plenty enough ways. Important thing after selecting our audio settings is to click the plus button on the right to submit/add our settings to audio queue.

Next sub tab inside config to set is path, where are wc, kitchen and dinning rooms for hybrid to go do its thing? One can set them to use the same as input path. And still this can be override, more on that later.

Our last config sub-tab stop is at profiles, where one can create, save and set profiles in several ways. Personally I only use and set several global profiles and that's it. If one it trying and testing new settings this is also useful to keep record of the mess, je je

We are almost done, said the epileptic brain surgeon holding the bloody router. Back at the main tab, there's a generate checkbox which overrides general path settings and naming (this is what I use most of the time).
If one wants, can also override but still be able to choose the output and name

here you can keep an eye on what's hybrid doing and at what stage, also in last Log tab, useful is something goes wrong and one wants to try and find what it might have been, I need one like these that work with women.

For adding cut support aka TRIM see my previous post. There's support for avisynth script creation and a ton of other tweaking and sub quantifications magic matrix of intrinsic rubber worlds - honestly, other than some x264 and x265 settings, I haven't properly explore those - but as starting point I reckon this is enough =)

If in these forums there are people using this power program - and I bet there are - chim in, share your settings/findings, help others, participate, give back, ponder donating to selur and that's stuff.

Thanks for all of this. I've been looking at alternatives for conversion software for a while. I've definitely used ffmpeg, but this looks interesting. I'm a PC guy (I know I know) and a lot of people I work with demand ProRes files.

Maybe this application is not for average user, there are lots of software around free, cheap and expensive like that, Hybrid is in development and probably the design is something they will get better with time, I see this amazing project on heavy transcoding use, and pro very specific hands, cheers. Results for me are great.

@heradicattor ja ja ja not a joke buddy, just a photo of a guy carrying an (large) instrument... you know where I'm currently living there's a saying the optimal is enemy of good... go figure. Anyway I feel your pain, too many choices; If you ask me choose the girl with wooden leg, she'll run slower and you'ld always know where (tak tak tak) :P

make Hybrid portable (Windows only):install Hybrid on a systemcopy the Hybrid folder to a separate folderdeinstall Hybridcreate a new subfolder inside the new folder i.e. 'settings'create a misc.ini (if not preset in the folder) and change it's content to[General] settingPath=.\settings

@VK I didn't even know MadVR; fucking hell 1.564 thread pages... it must be really somethin' :-)
I am the guy who goes to the well and carries water for the camels, I really know nothin' bout the intricate delicacies of all this.
Do you think is it possible to implement it in this hybrid cross-platform project?

It's been a while since Joel Hruska's last update, but he's still hard at work upscaling the variable-frame-rate Deep Space Nine to 4K. Here's what he's been working on, along with some of what hasn't worked.

load the files into handbrake
In the video tab:
Set it to mkv, h265 10bit, cbr (constant frame rate), same as source as the frame rate; unless you know it needs to be set to a specific frame rate, set the encode speed to slow. You can use the RF value, or set a specific bit rate.

In the Filters tab:
set detelecine to default, set deinterlace to bob, interlace detection to default.
The denoise is where your time will be eaten if you apply a filter. If you want to clean the source of some film grain set it to NLmeans medium grain and you will retain quality and remove film grain. If you want to retain film grain and details, on the video tab set the encoder tune to grain.

Seeing as you can CLI, maybe look into hybrid, staxrip or other AVI scripted frontends so you will be able to use QTGMC interlace filters etc. Fair warning, you need to understand video to grok these tools.

For Voyager and DS9, you need to encode variable frame rate with 2 constant frame rates: 23.976 for only telecine from the negatives, and 29.97 for early Voyager and some DS9 CG. The credits also run at 59.94i, so you need to discard one field.
