[REL] Rapture (1965)

[Night457]

I'm still waiting for that AI subtitle maker that can automate the job of transcribing from an audio track, creating subs, and doing translations. Many hours of tedious work done for you! Maybe someday.

I felt it was time to requote this pipedream post from back in the ancient times of 2021.

Yeah I was also today reading this and thinking how fast AI has moved in just 2 years. Hell, I was a member in one of the earliest deepfake communities, where the original DeepFakes developer discussed his work.

Yeah, omni-lingual dialogue transcribers and translators aren't just pie in the sky now.

That deepfake video of Barack Obama calling Donald Trump a douche bag still cracks me up. In the future there'll be a whole industry around secure video devices, with record once only media that can't be altered. If you can't show unbroken chain of custody between a secure camera and the court AV evidence probably won't be admissible.

It's possible to do a blend of a de-noised version with the original films natural grain. Then play with the percent of the 2 video files to find a good balance. But denoising a 1080p film takes about 30 hours on my graphics card. It was still a 300Euro card at the time! The PC pulls about 350w instead of 150w when doing this - warming my study quite nicely! God knows how Ghost's laptop-based graphics card does this in a third the time of mine, and without melting through his desk!
I just did a test of Artemis DeHalo which gives stunning results on preview - but it says "1 day 17 hours" to complete It's rendering at 1.03 frames per second to give an idea of how slow it is!

Here's a screenshot to show what Topaz's Artemis DeHalo can do (it actually softens it a bit - but that can be corrected in Handbrake by running a medium sharpness filter). Topaz in one view shows the before/after effect. The right hand-side still has a strong grain effect - (level 2.9, grain size 1)

Here's a test of 3x 5 second scenes I encoded to show what the after video would look like... maybe too little grain for some people

In each clip I did a final encode with Handbrake and did apply the medium sharpness filter to remove the softness Topaz's filter added.

Nice!

The full film - DeNoised/degrained in Topaz to look like the above sample image / samples. Same 1080p resolution, conveniently now only 3gb (a lot smaller filesize for same quality when the film has a lot less grain!).
I've included again the same audio tracks (english dialogue + english commentary)

If someone can upload into eMule.

As you can see it's retained all the skin tone detail - but removed the grain.
Note I left a 2.5 grain size Topaz filter on the film so it didn't look like zero grain!

Thanks Sir David!

Thanks, David32441.

But why the Dehalo model? There aren't any halos in the video.

It looks a bit too clean for my taste. I would have added more grain and a smaller grain size. Just my personal taste...

[David32441]

I'm no expert byt from what I've seen DeHalo removes the grain but retains the detail better than medium which we know can make things look plasticy. Medium sometimes removes the grain and leaves a lot if the grain is heavy.
Actually - I did spot contrast halos in some of th outdoor shots. Between a shirt and the sky - and this removed that too. A dehalo and a slight sharpen filter on the Handbrake encode I find cancel each other because DeHalo can have a slight softening effect.
I wanted it to have a remaster 4k look - hence the fine grain. Also, too much grain and the file size gets bigger which is impractical. I wanted only enough grain to cover any smoothing and stop bands in the sky - give it a film texture. I might up it slightly if I redid it - but it took 2+ days to process!

This is after DeHalo - before it looked worse. A strong white line around his dark suit

and at 300% it's a bit more obvious

it's only visible in a few shots of high contrast
I saw you did a great dehalo processing job on a film in the last few weeks. Can't recall the film, but what software did you use Ghost.
