  • Uncompressed 8 bit real time

    Posted by Erik Mickelson on January 20, 2008 at 5:55 am

    Frame Size 1280×720 HDTV, 29.97fps, Uncompressed 8-bit 4:2:2, Pixel aspect(square or NTSC-CCIR 60 doesn’t matter), Field dominance lower.

    The problem (if it is a problem).
    When trying to playback my sequence the render line is red.
    So what you may ask?
    Well, I get “real time” playback as long as my Canvas window crops a portion of the viewable area. 50%, 100%, 200% all try(and succeed) to playback dynamic RT even while the timeline shows a red bar, as long as a crop a portion of the playback canvas.

    Now when I view the canvas with no image cropping(viewing the whole clip size with the grey border around the clip), I get the “Unrendered” blue screen.

    Crop = Real Time
    Un-cropped = Unrendered

    Funny, Huh?

    Sounds like a mismatch between media and timeline settings.

    BTW, shouldn’t setings for HD be upper field dominant?

    It’s not the mismatch I am commenting on, sorry if that was not clear.
    I am commenting on the fact that I get RT performance and not the blue Unrendered screen as long as I make sure that the Canvas window is overlapping the viewable area. I still have the red line over my footage in the timeline, but I get to work as if it is an RT yellow line.

    Just wondering if this is an undocumented “feature”.

    Never heard of it. Interesting.

    Yeah, probably should be upper field. How about setting the fields to “none”? What are your thoughts on doing that?

    Thanks

    [Erik Mickelson] “How about setting the fields to “none”? What are your thoughts on doing that?”

    Erik,

    You must precisely match the timeline settings to the footage, you can’t just select no fields if there are fields or lower if the footage is upper. This is why I initially pointed out to you that you had a mismatch.

    Why do you have Fields turned on? I’ve never seen 720 interlaced footage. Only 720p. You should be set to None. If you did an Easy Setup for 720 8bit uncompressed, it should have preset you to 720/59.94 Progressive.

    It doesn’t matter if fields are turned on or off, it just does not matter. I was just messing around and found this. Like I said before, the issue is not fields but that I can put anything on the timeline and get RT performance as long as the canvas window is cropping the image. I just included whatever I had selected at the time I wrote the post. There is no relevance to the timeline specs except for the 8-bit 4:2:2 codec. It really just shows the independence of FCP, being able to preview even when there is a red line above the timeline. Is this hard to understand/explain? I am wondering of this is normal for FCP?

    Frame Size 1280×720 HDTV, 59.94fps(29.97 doesn’t matter), Uncompressed 8-bit 4:2:2, Pixel aspect(square or NTSC-CCIR 60 doesn’t matter), Field dominance none(upper/lower doesn’t matter). There – I switched it – same outcome as before.
