Activity Forums Compression Techniques MOV to DVD

  • Posted by Mike Janson on February 9, 2009 at 12:21 am

    Am I wrong or is it a myth that a 720×480 quicktime will transfer cleanly to DVD with proper compression? No matter how much I finesse my compressor’s VBR, the titling always ends up stairsteppy and images are slightly blurry — am I wasting my time trying to recreate the clean look of my original quicktime just so I can hand over a media disc the grunting client can understand, put in machine, and press play?

    “Am I wrong or is it a myth that a 720×480 quicktime will transfer cleanly to DVD with proper compression”

    It’s perfectly possibly to do. You’ll need to give us a lot more information about your source clip and the setting you are using before we could figure out why the titles look bad.

    thnx for getting back paul –

    the clip was created in after effects (just graphic elements in motion, no imported video)
    720×480
    square pixels
    dur 10 secs (when i’m done with the project it’ll be 2-3 minutes long)

    rendered as lossless mov, 72 megs total
    (also rendered as mpeg2-dvd on another try)

    imported into encore
    transcode setting ‘ntsc dv high quality 7mb vbr 2 pass’
    the build results in an 8 meg file

    viewing the output w apple’s dvd player looks fine when viewed in actual size – makes sense – but i need something to look sharp full screen and this isn’t adequately scaling up – am i wrong to start off at 720×480 in after effects?

    thnx again
    mike

    Err, my name isn’t Paul, but anyhow…..

    720×480 is a non-square pixel format. You should be rendering out of AE as 640×480, if the project is 4:3.
