    720x486 vs 640x480 resize for 1080

    Whats the correct resize for 640x480 brought in uprezed and streched to 1080?

    If you do a standard 4x3 resize to 16x9 it looks wierd, to tall.  If we blow up 25 percent vertical vs 33 percent it looks better but don't know if that's technicly right?

     

    Any ideas?

    There's going to be a crop in the picture when you try to properly fit a 4x3 to a wide box (maintaining proportion). You can simply use an effect in Avid and set it properly...i think it's called REFORMAT?

    that's kind of to the point of my question.

     

    Reformat does a 33 percent blow up to 720x486 non square pixle 4x3.

    640x480 is square pixle and reformat does the same 33 percent blow up which makes the image look streched tall.

     

    By using 3d warp 25percent looks right but i'm not sure its the real percentage.

     

    If any of that makes....

    Here's a quick example I made:

    1. First, you must import the 4x3 source to fit format raster. (import setting/image size)

    2. Drop the clip in your edit timeline.

    3. Use the Pan&Scan/Reformat effect.

    2. I need to set just the first two boxes. Notice the projected crop/output on the effect preview. Apply.

    I hope it helps. enjoy!
