How to use compressor

 First of all open a Final Cut Pro project. Then you need to click File, Send to, then clicked Compressor. When the Compressor opens you have to find a file called 'DVD:Best Quality 90 minutes' in Settings, when you find the file you have to click on it and as it expands you will see two other files called 'Dolby Digital Professional 2.0' and 'MPEG-2 6.2Mbps 2-pass'. click on 'Dolby Digital Professional 2.0' and drag it up to Sequence 1.



After you have dragged the file called 'Dolby Digital Professional 2.0 up to Sequence 1,  do exactly the same thing with 'MPEG-2 6.2Mbps 2-pass'.



After you've dragged both files up to Sequence 1 click on the second file in Sequence 1, and go to Inspector. Inspector allows you to change Video Format, Frame Rate,Aspect Ratio and also Field Dominance. 



Next thing  to do is click on Stream Usage to make sure that the Stream usage is SD DVD.



Click on Video Format and change it from NTSC to PAL. Then chang the Video Format to PAL, you will see Frame Rate automatically change from 29.97 to 25. You also have to change the Field Dominance from Bottom First to Top First.



Then click Quality in 'Inspector'. Quality option allows you to change the Mode, Average Bit Rate, Maximum bit Rate, and Motion Estimation.



Finally you have to  choose Mode:Two pass VBR Best, it goes through every field and makes sure the quality is the best when it compresses the file, although the only problem with Two pass VBR Best mode is that it's slow and it takes a long time to compress. After you check that the  Mode is Two pass VBR Best, change the Average Bit Rate from 6.2 to 6.8Mbps and change the Maximum Bit Rate from 7.7 to 8.0Mbps.Motion estimation had to be: Best.
