Thread: LW camera aspect help

    LW camera aspect help

    I need advice on setting up a camera for a short animation...most of my work is for print and this new project I've decide to take on has me a wee bit stumped

    LW has ntsc at 720 x 486 at 0.9 aspect ratio and
    nstc widescreen 720 x 486 at 1.2

    however when I view a couple of frames in both formats the images are not in proportion and 1.2 is really tall..if I manually change the aspect ratio to 1.0 then everythign is looks fine

    how do I know if using the default aspect ratio for either will produce a normal looking video?

    thanks in advance for your help

    Because it will? You are looking on the images on your monitor, but if you look at them on a video monitor they will look fine.

    That's something that I would like Lw to do. Show the renders with aspect correction in the image viewer. It does it in the render status window.

    A Video Frame (NTSC or PAL) consists of 2 fields, the odd and the even.
    NTSC frame consists of 60 fields, PAL consists of 50 fields.

    Fields are more visible when there is fast motion on the footage and this causes flickering.

    Deinterlace simply eliminates the one of the two fields (either the odd or the even) or interpolates the result in order to eliminate the visible flicker.

    DONT apply deinterlace on non-videosize footage.

    thanks for the tip..so to be clear..when I render the final sequnce (6 second)
    I'll be using NTSC (widescreeen) I should leave the default settign sin tact correct?

    Once it's rendered I will be sendign over to clients for final complilation onto their project.
