  Converting avi using compressor

  Posted by James Bayliss-smith on December 3, 2010 at 4:06 am

  Hi there I’ve just received some archive footage that I would like to use in my documentary. They are all avi files. I’d like to use compressor to convert them for use in Final Cut Pro. I used an application called VideoSpec to check them out here is the report

  *** General Parameters ***

  – Encoding library: Undefined
  – Additional Parameters: Bits/(Pixel*Frame) ratio: 21.333

  I imported them into FCP and I got the error message: The following media files are not optimised for final cut pro.

  My instinct is to convert them all to ProRes 422 using Compressor. Is this the way forward?

  If I convert them to ProRes422 should I up-res them to HD frmae size (albeit 4:3)?

  Should it be HQ?

  What is the Format: Apple FCP Uncompressed 10-bit 4:2:2?

  My ultimate use for them will be in and HD (HDV) documentary 16:9. I may crop them so they are 16:9 aspect ratio. All my footage was captured as DV but I will ultimately recapture all the tapes at ProRes422 1920×1080 for final post-production. I am also using some archive from a DVD. I have converted the DVD using MPEG Streamclip.

  Again should I up-res thee DVD footage if my ultimate project will be 1920 X 1080?

  I know that FCP can handle different formats in the timeline but I’m a little confused about the whole up-ressing business. I would say 95% of my documentary is HDV so I would like to make an HD version but I don’t understand how to properly use the SD footage, both archive and stuff I shot not in HDV

  Should I up-res the DV footage as well as the archive?

  Any help on any of these points would be much appreciated,

  All the best
