    Hi,

    I have DV footage in a DV sequence nest, and I plan on making a 10 bit uncompressed 4:2:2 Quicktime movie so that my subtitles look sharper. My question is, if I nest the DV sequence including titles and then place it into a 10 bit sequence, does it automatically uprez the titles to 10 bit? Because I tried this and when I zoom into the lettering there is some white aliasing in the yellow subtitle. So I’m wondering whether I should place the titles separately from the picture nest in the 10 bit sequence. Also, should I render the 10 bit sequence before exporting the Quicktime?

    Thanks,
    Alexander

    You need to set “Render all YUV material in High Precision”. Otherwise your DV footage will be rendered in 8b.

    OK, I’ve done some tests. My theory is that I made 2 mistakes:

    A. I made a nest of my DV sequence including titles and dropped that on a 10 bit sequence.
    B. I exported a Quicktime movie without rendering that DV sequence nest.

    So I believe my workflow solution is:
    1. Nest only the picture of my DV sequence.
    2. Drop that nest onto a 10 bit sequence.
    3. Copy and paste FCP text titles from the DV sequence to track V2 of the 10 bit sequence.
    4. Render
    5. Export to Quicktime movie.

    I tried Rafael’s suggestion and could not tell the difference. But despite these improvements, I still notice a bit of white in my titles:

    Is this the best quality I can squeeze out of 10 bit titles?

    Thanks for info.

    Hi Alexander,
    What are you using to make the titles in FC?
    Have you set the canvas at 100%?

    Text generator. I zoomed in on the canvas 800%

    Alexander,
    Please don’t use the FC text generator. Nobody do it. In fact it shouldn’t be in FC.
    Even if you want to do something simple, use Boris 3D. Is really good.
    If you want monitoring properly, you need to set your canvas at 100%. Any other setting will give you a preview with no accuracy.
