    Hey everyone,
    ive got a very urgent problem with apple`s compressor:

    i have an assignment to export several final cut projects as mpeg2 (transport stream).
    Since i was unable to export those files with final cut, i exported it to compressor and tried to export it there.
    After exporting, i noticed that the interlace looks really horrible with the preset of the mpeg2 transport stream, so i created a custom mpeg2 transport stream - resulting in not having any sound.

    my question is:
    how can i get the best results (audio + video + good de-interlacing) with mpeg in compressor?

    requirements are:

    -mpeg 2 transport stream
    -PAL (720x576)
    - audio & video in same export-file

    i would be very thankful for any help and its very urgent so i`d appreciate fast answers :)
    thanks !

    Have your deinterlace problems to do with wrongly chosen field-dominance (odd/even). Try the other one.

    Export with quicktime conversion should be possible (from fcp)
    Else if you need quick resolution, try exporting a quicktime and then conversion to mpeg2 (for instance with compressor or mpeg streamclip, or...)

    No time to look into things, but regarding your hurry some quick ideas

    Good luck

    Do the requirements call for deinterlacing? How is the final product going to be used (view on computers, viewed on TVs, going out for broadcast, etc.,)? I ask because if you deinterlace when you shouldn't all you are doing is damaging the quality of the video for no reason.

    first of all: thanks for the answers. appreciated :)

    @ Lethalwolfe:
    i cant tell you how the final product is gonna be used since we dont get the information from our customer.
    De-interlacing is not explicitely wanted, but the material really looks horrible without interlacing and im quite sure thats not the result we are suposed to deliver.

    mpeg2 with quicktime conversion is not possible in fcp, im afraid. i tried it.
    i might try the quicktime export and convert it to mpeg2 afterwards - idea from you, Richardthe4th, thanks

    that is necessary information before you ever agree to a video job (or any job really).

    are you viewing it on a proper broadcast monitor? you probably aren't... and unfortunately that is the only way you can actually judge whether your video has a problem or not. The FCP canvas is not representative of quality at all.

    I can't believe how many folks on here seem to only be viewing their editing (sometimes for profit!) on their iMac monitor rather than having it play through a broadcast monitor. I used a simple color TV for that purpose a couple years back, just hooked up through my camcorder while allowing play-through.

    iMovie and FCP playback on a computer screen will not look the same as it will/does on a TV. If this video is destined for TV screen playback, it's imperative to be able to view it on an external video monitor.

    And yes...not knowing how this will be used/displayed??? That's very odd. I can't see how you can do a job properly without knowing the final format/customer need. :confused:
