  • Sony Vegas Pro 11; Pixel format setting?

    Posted by Rafael Ortiz on January 27, 2013 at 2:41 am

    Hey guys, so I’m having a bit of a dilemma. I’m rendering a video I made shooting with my 5D-MKII. My original pixel format in the project settings has always been set to 8-bit. Which I’ve been using for a long time now with out issues.

    But I just recently read that using 32 bit floating would add some improvements, etc. So I decided to try rendering out a video using 32 bit float(video levels)

    I went ahead and rendered a video under 32 bit floating(video-level) without any transitions or effects. And it seems to look better than the 8-bit.

    BUT when I applied transitions, effects, etc. under 32 bit floating(video level) with 2.222(compositing gamma) and rendered the video. The transitions/fx gets all screwed up, the areas where I added transitions or effects flickers or just goes haywire for some reason.

    Is there any way to fix this issue? Thanks guys!

    To cut a long story short:
    Just continue to do your renders using your 8-bit pixel format.

    [Rafael Ortiz] “But I just recently read that using 32 bit floating would add some improvements, etc. So I decided to try rendering out a video using 32 bit float(video levels)”

    Where did you read that? Because Sony says that 32-bit floating point (video levels) is recommended when working with 10-bit YUV input/output or when using xvYCC/x.v.Color media. Since you are using neither, you should not be using 32-bit unless you are solving a specific problem when using 8-bit input/output, because the 32-bit floating point (video levels) setting can prevent banding from compositing that contains fades, feathered edges, or gradients.

    Video plug-ins and media generators that support floating-point processing are included in the 32-bit floating point folder in the Transitions, Video FX, Media Generators, Compositors, and Plug-In Manager windows. You should not be using any that don’t support 32-bit so that may be your problem.

    Use 8-bit and be happy that everything works like it should. 😉

    I see, what type of footages utilize 10 bit yuv input/output?

    Something captured from a device like the BlackMagic Designs HDLink or DeckLink Quad or AJA KONA other SDI capture device.

    I see, and it also applies to video/cinema cameras that record 10-bit correct? Not just external recorders like the ones you mentioned.

    If the camera shoots 10-bit YUV yes.

    Got it, thanks for the info!

    And is the reason why my footage had problems with transitions/fx is due to having less color information/values than a 10-bit footage? Thanks again

    No. The reason may have been that you were using a transition or FX on a 32-bit project that wasn’t designed for 32-bit processing so it wasn’t expecting the 32-bit information that Vegas was feeding it and it did not perform properly. If you stick to only using 32-bit transitions and FX it should work fine regardless of the footage but using 32-bit pixel format on footage that does not require it has no real benefit and takes longer to process and render.

    I see, but interesting enough since I use Sony Vegas Pro 11. Under the Transitions and Video FX tabs, there’s a folder titled “32-bit floating” which utilizes 32-bit floating effects. And that’s what I used when I changed the property settings to 32-bit.

    So I don’t understand why it still screws up.

    It has had it’s share if bugs which is why I stay away from it and only recommend using it when absolutely needed. You might want to contact Sony and see what they say. if you are using all 32-bit transitions and FX it should work.
