I'm using the latest version of compressor (four). I am exporting a movie from my timeline of some 57 minutes to a master .mov file using 'current settings' from the timeline. My compressor settings are that I am creating a standard definition DVD with the default settings, apart from adding a very small  amount of sharpness, as I would normally do.

 

Problem:

 

when I play back the movie on my HD 1080p TV, the video looks interlaced. When I tried to re-encode using deinterlace option, the same problem was worse, showing what looked like interlaced lines on the horizontals. I didn't have this problem with previous versions of compressor when using exactly the same method.

 

Anyone else experiencing similar problems?

    What is the format of your movie source? Best if you take a screen shot of the Inspector summary and post here.

    I wouldn't be surprised if the difference in what you're seeing from v4 compared to v3 has more to do with your material (lighting, background, movementt) than it does with Compressor. However, it would be most interesting for you to make that comparison yourself – doing the job in whatever earlier Compressor version you still have access to.

     

    BTW, whart flavor ProRes did you use?

     

    But a couple of things: Was the footage shot progressive or interlaced? Definitely don't de-interlace if progressive and probably don't even if it were shot interlaced. If you feel you must de-interlace, use Frame Controls and select Motion Compensated; don't use the de-interlace option in the filters tab.

     

    I'm not a fan of the new DVD video quality settings (and I use 3.5 for DVD encodes)…and I recommend changing to two pass VBR – unless your movie is fairly static, like an interview. Furthermore, the new bit rate settings are very aggressive, and I'd lower them so the average is around 7.2 Mbs.

     

    Try encoding a small but representative section with a variety of adjustments and bring them into DVD Studio pro to test…waste a disk or two. If you don't get satisfactory results, break it into two jobs…in the first, do a re-size to SD – while staying in Pro Res – with Frame Controls on and resize filter set to Best. Then take that outut file and make your MPEG-2.

     

    Good luck.

    BTW, when I asked about the flavor of Pro Res, I'm asking you to verify that Proxy wasn't inadvertently used.

    Open the movie (that you used for Compressor's source file) in Quick Time Player and hit command i to bring up the QT Inspector. It will give you the format info.

    Agree.

    So try the steps with small test files that I suggested in my earlier post.

     

    You don't have to use the preset. Use it as a starting point. Experiment with adjusting the quality controls and frame controls. When you find something you like, save it as a custom preset.

     

    Let us know how much improvement you are are able to achieve.

     

    Good luck.
