  • pulling my hair out over pixel aspect

    Hey, I did go into the “read this first” section and I really did try to understand. Now maybe if someone could put this into easier to understand terms or just tell me what to do.
    I filmed some sd DV 16 x 9 footage with my HDR-FX1. I want to import this into After Effects and do a little work.
    So I create a new project in After Effects, then I create a new composition. I use the NTSC DV Widescreen preset with a 720 x 480 dimension. Pixel aspect ratio is D1/DV NTSC Widescreen (1.2) with a frame rate of 29.97 frames per second. Lock aspect ratio to 3:2 is unchecked. This is exactly what the footage I shot is.
    I open the comp and the “comp” doesn’t look 16:9 at all, it looks 4:3 to me, like old school TV size. I pull the footage in and have to incessantly mess with the interpretation to get it to fit without having to resize it manually and then I have to choose and interpretation which is completely incorrect.
    I am sure I am just missing something. Please help me overcome this hurdle!

    At the bottom of the Comp window check Pixel Aspect Ratio Correction. Your monitor displays pixels as square, so when you tell your computer that you have pixels that are wider (1.2 aspect ratio) it appears to shrink because it’s displaying them as 1:1 aspect ratio. Same goes for .9 aspect ratio but they appear wider.

    When you toggle this it’ll appear as it should, but may be a bit rough around the edges. Don’t worry about that, it’ll play like normal.
