I am working on an Aliens project preserving the original colour and audio of the theatrical release.

I found the Aliens Special Edition THX PAL DVD at my mum’s house and I own the blu-ray. My goal is to have the DVD video synced to the blu-ray 4.1, fan-made 4ch stereo audio and subtitles.

Problems:

  • DVD video is 25 FPS and the blu-ray is 23.976 FPS
  • DVD audio is higher pitch
  • When converting to 29.97 NTSC via ffmpeg or 23.976 NTSC with Handbrake, the runtime stays the same.

When converting from 25 FPS to 23.97 FPS, the runtime should go from 2hr 28min to 2hr 34min because PAL is sped up 4%.

I am using Mac so any solution for that would be preferable, I can use Windows as a last resort but it’s been 10 years since I used it regularly.

My eventual goal is to try to colour match the DVD to the blu-ray but I’ll settle for this for now. Thanks in advance for any help with making this a reality.
