    color and contrast different from Premiere Pro 2 DVD creation

    kdlla Community Member
      I found after creating DVD's via Premiere Pro 2 are more saturated and more neutral in color vs encoding through Encore.
      I made a si8de by side test, converted them back to AVI and grabbed the same still of each. The Encore still was lower in contrast (flatter) and a slight bit warmer. over all the DVD compression from PP2 gives a richer look. If you are a film maker or photographer this matters a lot, but not for most users.
      the file sizes from premiere are bigger. for example a 8mbs from a 7:30 avi compression on premiere resulted in 544mb while a 9.4 compression via encore 2 resulted in 464 mb. when changing the mbs from 8-9.4 mbs it resulted in exactly the same size file 464mb. even when starting a new project, which means that there might be a bug and encoding on a unknown predetermined mbs, probably 7. This would explain the flatter look of the Encore 2 compression.
      Does anyone know how to find out at what rate a dvd has been encoded after it's done? knowing that there isn't any difference in the file size between 8mbs and 9.4 mbs shows that there must be a problem.
      This test was done with the Encore DVD 2 trial version. I have vs 1.51 as well and will make a test on this one as well. to see if there is the same problem.

          1. Can you detail your exact method, step-by-step, for both Premiere and Encore?

          2. Did you use the exact same source files for all tests, or just files that were the same duration?

          3. Be sure to include project settings and program preferences for both applications.

          The results you posted are unexpected and unusual.

          Thanks,

            How is the quality of encoding in Premiere 2.0 and Encore 2.0 compared to their 1.5 version counterparts?

            Has there been any changes in the encoders in version 2.0?

            Thanks. Roy

              encode encoded in premiere 2 at the highest level 9mbs (didn't chapter for a simple auto disk, this is disabled in pp2 but you can save as an mpg2 and import for chaptering in Encore2)

              2. Did you use the exact same source files for all tests, or just files that were the same duration?
              Exactly the same source file, when importing the mpg2 into premiere i simply imported each file in the timelime and saved exactly the frame of each mpg2. All this started when i first compared 2 encodings from a film directors reel where quality is crucial, and saw it immidiatly when playing the 2 different dvd's of the same reel on a DVD player (JVC) and Sony monitor.

              3. Be sure to include project settings and program preferences for both applications.

              encore 2 encoded at cbr 1x 9mbps (highest)
              Premiere 2 encoded at cbr 1x 8mbps (highest)
              when setting to 9mbps in PP2 I get the3 following warning:
              Total Video and audio bitrate (10.536 Mbs) exceeds maximum allowable bitrate (10.030 Mbps) for DVD type of muxing.
              So i reduced the bitrate to 8 and still got a file of 557mb and better color and contrast than Encore2.
              The final results of encoding in PP2 gives an identical DVD mpg as far as color and contrast to the original AVI.
              When encoding at the max rate of 9 in PP1.5 i never got this warning.

              I just repeated the above test on more time in PP2 and Encore DVD 2
              they must use a different codec for Encore2 than PP2.
              Besides the color and gamma shift the image size horizontally is a slight bit different (larger) than the one done with PP2, but not verically.

              you can also encode in PP2 save it as a multiplexed mpg2 file and than chapter it for the final dvd in encore2 which gives you the higher quality results of PP2.

                as for the difference between pp1.5 and 2 the DVD output quality is the same except for the pop up at 9 mbps where i now have to set it to 8mbps (as mentioned above) , must be a bug. Even though I always had Encore 1.5 i never had to use it since PP1.5 had all the chaptering functions (never needed a menu only autoplay). This funtion has now been disabled in PP2.

                  Klaus,

                  Don't know how this is possible as PPro 2.0 and Encore 2.0 both use the same exact MPEG-2 encoder.

                  Make sure that all MPEG-2 parameters are exactly the same in both applications. Also make sure that you are not somehow losing image quality or colorspace exporting AVI or QuickTime from PPro 2 (assuming you are importing an AVI or MOV file into Encore 2.0 for encoding).
