  • PCM digital audio from Laserdisc to PC via S/PDIF bit-perfect 16bit 44,1KHz stereo
  • DTS digital audio from Laserdisc to PC via S/PDIF bit-perfect 16bit 44,1KHz stereo


Project status: VIDEO PROCESSING IN PROGRESS.

Captures:

I decided to use mainly the Pioneer DVL-909 as its video quality (resolution, noise, drop outs) is better than the others; the connection used is S-Video, as the laserdisc player comb filter seems slightly better than the capture card's; I also used the Pioneer CLD-D925 to make a third capture of one of the PAL italian laserdisc due to median process.

 

Video treatment:

main video parts are from two italian PAL laserdisc copies, one of them captured by two different laserdisc players; these captures are time and space aligned, then with AviSynth median scripts are overlaid to eliminate some noise and drop-outs; the english PAL laserdisc single capture is used when italian subtitles are on pictures, to use english subtitles or no subtitles at all, while the NTSC DTS laserdisc single capture is used where the italian and english PAL laserdiscs fades off at the end of a side, and fade on in the other side (italian) or disc (english); derainbowing, little noise reduction (new scrip used, less aggressive) and sharpen; no color correction, only levels are adjusted minimally to let the three sources match in saturation, brightness and contrast; upconversion from PAL 720x576 4:3 and NTSC 720x480 to 1280x720 16:9 - no frames are lost in the process, at the contrary, there are few frames in some laserdiscs and not in the others, so at the end the final video will show some frames more than the single capture.

 

Video tracks:

  • the original PAL video format is 720x576@25fps 1.85:1 letterbox, with a video resolution of visible image around 700x412; the original NTSC video format is 720x480@29.97fps 1.85:1 letterbox, with a video resolution of visible image around 700x346; captured using the Lagarith lossless codec; video is upconverted to 1280x692 1.85:1, inside a 1280x720pixel 16:9 frame, using x264 code; frame rate changed from 25fps to 23.976fps with TSmuxeR.

 

Audio treatment:

the original soundtracks are: english, italian and french laserdisc PCM 16bit 44.1KHz 1441kbps stereo, Dolby Surround encoded, and U.S. laserdisc DTS THX 16bit 44.1KHz 1441kbps 5.1 discrete surround.

All the soundtracks will be converted only when necessary; from PAL 25fps to 23.976fps (pitch corrected); from 44.1KHz to 48KHz; from PCM 2.0 to AC3 2.0; from DTS 5.1 to AC3 5.1.

 

AVCHD Audio tracks:

  • english soundtrack from U.K. PAL laserdisc, PCM 2.0 Dolby Surround Encoded converted to AC3 2.0 384kbps 48KHz
  • italian soundtrack from italian PAL laserdisc, PCM 2.0  Dolby Surround Encoded converted to AC3 2.0 384kbps 48KHz
  • french soundtrack from french PAL laserdisc, PCM 2.0  Dolby Surround Encoded converted to AC3 2.0 384kbps 48KHz

 

BD Audio tracks:

  • english soundtrack from U.S. NTSC DTS THX laserdisc, DTS 5.1 Digital Surround converted to 1536kbps 48KHz
  • english soundtrack from U.K. PAL laserdisc, PCM 2.0 Dolby Surround Encoded converted to 1536kbps 48KHz
  • italian soundtrack from italian PAL laserdisc, PCM 2.0 Dolby Surround Encoded converted to 1536kbps 48KHz
  • french soundtrack from french PAL laserdisc, PCM 2.0  Dolby Surround Encoded converted to 1536kbps 48KHz

 

Subtitles: based on the commercial Blu-Ray; SRT format, english full, italian (literal, transcripted from dialogs) and french full and forced.

 

Final formats:

  • AVCHD folder, 720p/23.976fps with three audio tracks and five subtitles (english full, italian and french full and forced)
  • BD folder, 720p/23.976fps with seven audio tracks (including DTS) and five subtitles (english full, italian and french full and forced)
  • other formats will maybe available in the future

 

Jobs to do for the next version:

  • try a non-Pioneer laserdisc player to avoid some edge halos
  • transcribe the french dialogs to do french literal subtitles
  • adding the eventual german and spanish laserdisc soundtracks, if someone will provide them
  • adding the corrisponding subtitles (possibly literal) for the eventual added soundtracks

 

To do later (maybe):

  • author AVCHD and Blu-Ray discs properly (menus, audio and sub tracks etc.)

 

Credits:

  • ilovewaterslides for the french laserdisc PCM soundtrack!

 

Self comments: Altought there are several BD original releases, they have some problems (IMHO): the 2011 BD has a lot of edge enhancement, and the 2013 3D BD shows different colors in comparison to the laserdisc and 2011 BD, some details in dark scenes are lost, and it could not be seen in 2D, as the companion 2D disc is merely a 2011 BD version; finally, the BD are more cropped than the laserdisc, and some small details, albeit not fundamental, are lost forever in BD, but still could be seen in this project.

As I like a lot the movie - it's the first laserdisc I've bought in 1995 brand new! - I remembered it was a really good laserdisc, with powerful colors and good resolution. This is my personal homage to one of my preferred movies!
