  • Firecoder and Aspect Ratio

    I use Adobe Premiere 1.5.1 for video editing and firecoder PCI-E card.
    The problem consists that at converting video, using premiere plug-in, in a aspect ratio 16:9 turned out video has a format 4:3 (the Premiere project and video source - widescreen)

    Thanks for assistance

    P.S.: Even if to put 1:1 aspect ratio - it is all the same received as a result 4:3, But if to use Ultra coder stand alone application - problems is not present.
    P.P.S: Have been reinstalled: Windows (XP Service Pack 2 and all update pack from Microsoft), Premiere 1.5.1, newest drivers for firecoder and other hardware. These actions have not solved a problem.
    P.P.P.S: Sorry for my bad English 8)

    Is your target MPEG-2 (for DVD authoring)??

    If the resulting footage is 4:3, is it anamorphic, or letterboxed?

      Yes, I convert video from Premiere timeline in MPEG2 PS for the further processing in DVDLab-Pro authoring software. And wide-screen video from Premiere timeline to become usual 4:3. But adjustments of the encoder are established on 16:9.

      I do not know, in adjustments of the encoder (plug-in for Adobe Premiere) there are no such installations.
      DVDLab-pro has function "MPEG header pach" - this options solves a problem... But it is not correct - plug-in should work

      P.S. As you see adjustments of the encoder (plug-in for Adobe Premiere) very poor (click on picture to enlarge (open in new window)):

      P.P.S. The encoder (plug-in for Adobe Premiere) has the name: Canopus Hardware MPEG Engine

        Looks like everything is correct from the encoding side as shown in the images (16:9 PAL video will still have pixel dimensions of 720x576).

        So are you saying that your DVD authoring package is not treating the footage as 16:9 anamorphic material?

          Yes! My authoring software (DVDLab-Pro) and my Player (InterVideo WinDVD and Windows Media Player)

            You mentioned that DVDLab Pro provides an option to alter MPEG headers? Surely this is what you need to do.

            It strikes me that for whatever reason, the headers that tell decoders that the MPEG stream is 16:9 anamorphic, are not being recognised correctly. I unfortunately don't have a FireCoder board on me at the moment to double-check..

              Try ReStream to correct the flags.
