I wouldn't call myself a veteran of movies but I've seen more than a couple. I like a variety of film of varying age. I guess I've seen a whole lot of 70's and 80's movies more than anything else. I actually don't watch as many movies as I used to, what with having adult responsibilities I use my spare time for things like Skating and Video Games more than movies. I still like to relax with a good film while I eat dinner and unwind.
Anyway, I'm mostly posting because I figure it may unlock a restriction so I can PM someone for a movie cut that I would like to get. I'm unsure if I'll stick around but just know I appreciate those of you who also have a love for movies, and especially restoration to it's original release. I've watched those, now quite famous, De-specialized versions of Star Wars IV, V, and V. I do think that, nostalgia aside, the historical and artistic importance of having a film in it's original theatrical release is a very important and worthwhile endeavor and I applaud all of those here working toward that. You have my utmost respect and I am humbled by the dedication and I feel as though the work being done here shows one to have a true and pure love for film which also commands great respect from me.
Anyway, sorry for my long winded introduction. Nice to meet you all and have a lovely day.

Ok so the new BD and 4K discs have new remixed sound and effects in the Atmos soundtrack.
But word is the lossy 5.1 is a downmix of the new track.
What options do we have? The JP LD sounded better to me than the US one, anyone know any more?

The Hitcher Regrade and Video Fix
Project Info
Been hoping for an HD version of The Hitcher for awhile. I knew it wouldn't happen in the USA as the rights to it and all the HBO films are in legal limbo. I was hopefully expecting it to appear in the UK since there was an excellent SE DVD which I had upscaled previously. So I was happy to hear about a German release. When I got a copy I was surprised to see that it was clearly a scan of a lower order print, maybe even a release print. And since it's not an OCN or IP scan then it comes with a whole host of issues. This project's goal is to either fix those problems or at least minimize them while tweaking other concerns.
1. Black Levels - Given the scan's probable origins, the master has had its brightness/black level boosted to counteract the look of black crush or loss of details. I separated the movie into 15 "scene section" and pinned the black level to 0 for the darkest areas for each section and then used curves on the shadows and mids to make sure as much detail is preserved. Even after that the shadows are not balanced correctly resulting in blacks that drift off into red or occasionally blue. I readjusted the shadows via curves to make them black as much as possible.

![[Image: ssngljx.jpg]](https://i.imgur.com/ssngljx.jpg)
Even with these adjustments my personal goal is to keep the colors as close to the original bd as possible.
2. Light leak - The scan has a lot of light leak on the sides. It increases towards the end and is more noticeable in dark scenes. I did what I could trying to minimize this but there is no way to get rid of it all.
3. Blown Highlights - I ran an effect to bring down the highs a bit but there is no information to be recovered in the highlights. They are blown. So, the highlights are what they are.
4. Compression Artifacts - Coming from a lower print there is a lot of grain and the encoder was unable to deal with it. I tried to separate the compression artifacts from the grain and ran a de-blocking filter. I think I was able to minimize the worst of it.
5. Logos/Credits - This is technically not wrong but still something I wanted to change. This scan has a tacked on Cannon logo at the beginning. That is correct since Cannon released the movie in European territories. In the US, HBO films had a deal with Tri-Star to release their films, whose logo you can see on the UK and US DVDs. So I took a vintage HD Tri-Star logo and put it in the beginning.
(notice the red in the shadows of the Canon logo)
![[Image: v54Po67.jpg]](https://i.imgur.com/v54Po67.jpg)
The print is clearly an English language print, most likely a US one given the credits. The exception is the one shot with the title card in it, whereas the title is the German Hitcher der Highway Killer with the Hauer's and Howell's name in the wrong font.

I upscaled this 19 second section from the UK DVD and will color correct it to match

As for the audio. There is nothing wrong with the English soundtrack on the German BD. It just sounds weak. So went about comparing every English soundtrack to find the best possible. There is no PCM track on a LD but Buster D was nice enough to cap the analog for Doombot and me. Comparing that, the German BD tracks, the UK DVD track and the US DVD track, I found that the 2 channel Dolby Digital track from the US DVD was, by far, the most dynamic. I converted this to PCM (for editing) and included it as the main track.

Audio:

BitPerfect: PCM Bit-Perfect Tester |

When archiving laserdiscs, we want to make sure we're copying exactly what is on the disc and not modifying it in any way. This cross-platform app is meant to help verify that your capture chain is setup correctly for "bit perfect" digital audio captures.
A bin/cue is included to burn to a CD, which is recorded through your capture setup. BitPerfect is then used to compare your recording to the reference and see if the samples in the stream are the same. There is also a noise generator included if you'd like a longer or shorter reference WAV, or you can just rip one of your music CDs and use a song. Just replace the reference.wav in the root directory with what you'd like to check against and you're ready to go.
Features:
- Easily test whether a digital recording is Bit Perfect or if 2 audio files are the same
- Snapshot feature analyzes WAV, FLAC, or RF64 (1.0 to 7.1 channels) for RMS, EBU R128 Loudness and Dynamic Range, Dual Mono, and 24-bit padding
- Noise Generator

Step 1: Burn the bin/cue to a CD-R (ImgBurn recommended)
Step 2: Play the CD-R on your LD player and record it through your capture setup. Leave a couple seconds of silence on either side of the recording when you export to ensure nothing is cut off (extra data before and after will not affect the test).
Step 3: Use the Tester to compare your recording with the reference WAV.

| "glue" HDR luma to SDR2HDR chroma |

Working on Mad Max, I thought if it's feasible to "glue" HDR luma from UHD to chroma from the regraded UHD HDR2SDR (using DVD as color reference), converted back to HDR.
Now, I could do everything with AviSynth, and finally convert to HEVC, what I'd like to know is how to preserve the HDR data of the UHD... is there any way to let the new encoded HEVC file retains original UHD HDR metadata?
