  • Compression Hell

    Hey-

    I finished a client project edited in AVID Media Composer Ver. 5 and am trying to compress the project to a quicktime movie for a DVD but every attempt has bad aliasing. I have tried saving it as a quicktime movie with H.264 compresson, deinterlaced and interlaced, 16 bit 48k stereo audio. I have also sent it to Sorensen squeeze, saving it as an MPEG 2 and MPEG 4, experiencing the same results. Any good links or suggestions?



    Thanks

    Brian

    What is the source material? For SD DVD you use MPEG-2 and AC3 (Dolby Digital) for the audio. Describe the "bad aliasing" and you're judging that on the Trinitron? Why de-interlace? Sounds like you are working in DV/NTSC?

      Compression Hell

      I shot on mini DV NTSC @ 29.97FPS. I tried compressing to MPEG2, but dont have the AC3 option. Im judging the bad alisising based on my computer monitor, client monitor and viewed on a burned DVD

        I don't know what kind of Compression tools you have with Media Composer. What is the version of Squeeze? You need to use a MPEG-2 video elementary stream at an appropriate bit-rate, say 5-6.5 Mbps and the audio SHOULD be AC3 but you can use AIFF, 16 bit, 48 kHz. What are you using to author the DVD?

            Describe your entire workflow. What are you exporting from Media Composer? Can you export out a QT file at "current settings," "self-contained." Bring that into iDVD and iDVD does the compression to MPEG-2 & audio. I'm assuming an older version of iDVD too? Anyway, I haven't used iDVD for a long time but it does that compression under it's own protocols.

              Export it self contained, current settings, and use that movie file for iDVD encoding.

              iDVD encodes itself, so deliver your original source movie codec to it.
