  1. Hi all

    I got some really shitty footage from an AVCHD camera in 720i, upper field.
    They want me to cut the material and produce a DVD.

    Ok, i cut it in Premiere, export as YUV AVI with all the same properties. (so far, so good)
    Then use virtual dub with YADIF for deinterlacing (keep upper field) and export as YUV again.

    Problem: in the last step, i loose my aspect ratio.
    when i import into encore, the video source seems to be 4:3.
    when i import the file i exported from premiere, everything is fine.

    do you guys have suggestions ?
    is there a easyer way to deinterlace?

    cheers

    There isn't really such a thing as 720i, so first let's figure out what you've actually got. Can you post a mediainfo report on your source files or at least tell us what camera it came from? Is your footage 1280x720?

    Second, Premiere -> Encore requires no intermediate encoding and that is usually the cleanest way to get there.

  4. When you import an asset just override what the program thinks of its aspect ratio.

    In encore, you would just right click the video in the clip bin and interpret to change the AR

    But you should answer the other questions , because it looks like there are serious issues with your workflow

  6. thanks for your quick replies!
    (yes.. not 720i, i meant 576i)

    the footage came on a sony memory stick, but it seems to be standard MPEG2 material.
    the wierd thing is, that its "upper field first". I thought MPEG standard was "lower field first"?

    2745 Kbps, 720*576 @ 25fps, MPEG PAL Version2, AC3 Audio

    would a DVD with MPEG2 50i upper field first run on every DVD standalone player?
    then i would use a dynamic link out of premiere and directly encode the material with encore.

    i tought DVD had to be lower field first, thats the reason why i tried to deinterlace.

    Interlaced MPEG video, DVD or otherwise, can be lower field first or upper field first. Just make sure it's flagged correctly. The field order flag just tells the player which of the two fields is supposed to be displayed first (you're supposed to see the fields one at a time).

    Edit your project in Premiere and send it to Encore via Adobe Dynamic link. If you need to reencode first it will tell you. There is no need for deinterlacing, there is no need for colorspace conversion, there is no need to change aspect ratio. If your current mpeg files fall within DVD specs, Encore may even be able to Smart Render parts of it.
