I had a load of old 8mm cine film converted and put onto DVD and they took up 2 x 4.7Gb discs. I converted them from UDF to AVI and ended up with 2 files just over 1Gb each. The original cine conversion was not done in any particular order so we have imported all the individual clips into Premier Pro and put them into the correct sequence, faded from one to the next and added titles, but no soundtrack. The final file is now a whopping 40Gb and too big to do anything with. Can anyone please tell us why it has saved to such a huge file and how we can reduce it without losing too much quality as we still want to add some background music to the project.
