Project status: RELEASED - you could find it on myspleen

Captures:

I finally decided to use the DTS NTSC laserdisc for video, as it seems that PAL laserdisc is only a NTSC-to-PAL conversion and has some issues. For audio, I captured the italian soundtrack from the PAL laserdisc, the english DTS soundtrack from the DTS NTSC laserdisc, and the AC3 soundtrack from the AC3 NTSC laserdisc via the RF demodulator.

Video treatment:

whole video is from the DTS NTSC laserdisc; derainbowing, little noise reduction (new script used, less aggressive) and sharpen; no color correction, only levels are adjusted minimally - saturation, brightness and contrast; upconversion from NTSC 720x480 4:3 to 1280x720 16:9.

Video tracks:

  • the original NTSC video format is 720x480@29.97fps 1.85:1 letterbox, telecined, with a video resolution of visible image around 700x346; video is upconverted to 1280x692 1.85:1, inside a 1280x720pixel 16:9 frame, using x264 code, double pass, bitrate used for BD is 16,5MBPS; IVTC applied to obtain the (near) theatrical frame rate of 23.976fps.

 

Audio treatment:

the original soundtracks are: U.S. laserdisc DTS THX 16bit 44.1KHz 1441kbps 5.1 discrete surround in english; U.S. laserdisc AC3 THX 16bit 48KHz 384kbps 5.1 discrete surround in english; PAL laserdiscs for italian and french, PCM 16bit 44.1KHz 1441kbps stereo, Dolby Surround encoded.

All the soundtracks will be converted only when necessary; from PAL 25fps to 23.976fps (pitch corrected); from 44.1KHz to 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.S. NTSC AC3 THX laserdisc, original untouched AC3 5.1 384kbps 48KHz
  • english soundtrack from U.S. NTSC AC3 THX laserdisc, PCM 2.0 Dolby Surround Encoded converted to 1536kbps 48KHz (maybe later)
  • 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:

  • BD folder, 720p/23.976fps with four audio tracks (including DTS) and english subtitles. -> RELEASED!
  • AVCHD folder, 720p/23.976fps with three audio tracks and english subtitles.

 

Jobs to do for the next version:

  • finishing the italian subtitles
  • transcribe the french dialogs to do french literal subtitles
  • adding the eventual german laserdisc soundtracks, if someone will provide them
  • adding the corrisponding subtitles (possibly literal) for the eventual german soundtrack

 

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: This is the companion project of Jurassic Park [ruLes]; altough I have not JP2 captures from BD to make comparisons, I'm pretty sure JP2 is like JP1, so probably its picture is cropped more than the laserdisc, and the colors are different too.
